CHAPTER 2

DESCRIPTION of SYSTEM and COMPONENTS

SECTION 2.0 — TracPipe FLEXIBLE GAS PIPING MATERIAL DESCRIPTION

1. TUBING

The TracPipe fuel gas piping system con- sists of corrugated, semi-rigid stainless steel tubing with brass mechanical attachment fittings terminating in NPT pipe fittings for easy attachment to traditional black iron pipe systems and direct connections to gas appliances. Tubing is available in sizes 3/8 inch, 1/2 inch 3/4 inch, 1 inch, 1-1/4 inch, 1-1/2 inch,and 2 inch. The 300 series stainless steel tubing is jacketed, with a non-metallic cover which provides ease of running through joists, studs, and other building components. The jacket is marked at one foot intervals with the amount of tubing left on the reel, for quick measurement.

2. FITTINGS

Straight NPT pipe fittings are standard and are available in sizes shown above to fit all tubing. Additional fittings include termination mount and flange-mount straight and 90 degree elbow fittings for termination of gas lines near movable appliances; and meter termination accessories for support of TracPipe at utility meter sets on building exteriors and roof penetrations. Tee fittings are available for addition of branch lines into tubing runs; reducer tees are available in popular sizes and pipe outlet tees terminate in pipe threads on the outlet leg for size changes utilizing available black iron reducer fittings.

3. ACCESSORIES

Accessories are available for expansion of the flexible piping material and additions to existing fuel gas piping systems. These accessories include:

A. Manifolds — allow parallel installations

with “home runs” to each appliance. 1/2 inch female NPT outlets and 3/4 inch

and 1/2 inch female NPT inlets. Large size manifolds are also available for use with commercial size TracPipe.

B. Pressure Regulators: pounds to inches -

for use in elevated pressure system installations (over 14 inches water column

- one half psi) to reduce pressure to standard low pressure for appliances. Available regulators include 1/2 and 3/4 inch sizes for natural and propane use and 1-1/4 inch size for natural gas. Regulators include approved vent limiters except 1-1/4" size.

C. Protection Devices-for use where flexible

piping passes through studs, joists and other building materials and is restricted from moving to avoid nails, screws and other puncture threats.

There are four striker plate configurations made from stamped steel and specially hardened to resist penetration from screws and pneumatic nail guns. These are quarter-striker, half striker fullstriker and 6" X 17" flat plate striker. Spiral wound galvanized steel “floppy” conduit is available for use as additional protection.

Some of the special usage features of TracPipe gas piping are outlined below:

1. Flexible gas piping is used to provide safe, efficient, timely installation of fuel gas piping within buildings, residential, commercial, and industrial, or for outdoor connections to appliances that are attached or in close proximity to the building.

D. Shut-off Valves-for use in elevated pres-

sure installations: 2 psi up to 5 psi. (Standard gas-cocks should be used at appliance stub outs and other low pressure areas of the piping system.) Brass lever-handle ball valves supplied by OmegaFlex are rated for 5 psi use and are available in 1/2 inch and 3/4 inch sizes.

SECTION 2.1 — MATERIAL USE AND LIMITATIONS

This Design and Installation Guide has been written in accordance with the most current edition of ANSI LC 1 CSA 6.26,

FUEL GAS PIPING SYSTEMS USING CORRUGATED STAINLESS STEEL TUBING (CSST).

This Design Guide is intended to aid the professional gas pipe installer in the design, installation and testing of flexible fuel gas piping systems for residential, commercial and industrial buildings. It is not possible for this guide to anticipate every variation in construction style, building configuration, appliance requirement, or local restriction. This document will not therefore cover every application. The user should either exercise his own engineering judgment on system design and installation, or seek technical input from other qualified sources. Additional information pertaining to gas piping systems is available from your local gas utility or propane supplier.

2. Flexible gas piping can be routed in most locations where traditional gas piping materials are installed: inside hollow wall cavities, along or through floor joists in basements, on top of the joists in attics, on roof tops or along soffits or in chases outside of buildings. TracPipe gas piping has been tested and is listed by CSA International for both outdoor and indoor use.

3. TracPipe is listed by CSA International

for fuel gas use in the USA and Canada for pressures up to 25 psi. For local gas utility approved use only, TracPipe has been tested for use up to 125 PSI for sizes 3/8" up to 1-1/4", and for use up to 25 psi for sizes 1-1/2" and 2".

4. In North America, the most common pressure for Natural Gas is 6-7 inches water column, standard low pressure. Elevated pressures of either 2 psi or one half psi are also available from utilities in most areas for new residential construction. 5 PSI systems are commonly installed in commercial or industrial buildings. Elevated pressures allow the use of smaller diameter piping, while providing for increased loads and longer length runs.

5. Flexible gas piping can be used for Natural gas and propane (Liquefied Petroleum gas) and other fuel gases recognized in NFPA 54 National Fuel Gas Code.

6. TracPipe CSST with the yellow polyethyl-

ene jacket has been tested by Underwriters Laboratory to UL723 (ASTM E84) Surface Burning Characteristics with flame spread and smoke density ratings meeting the

requirements of ANSI/CSA LC-1 for use in air ducts and plenums. It is mandatory, however, to follow fire and building code requirements in all installations. CounterStrike with black jacket requires removal of the jacket for use in air ducts or plenums.

7. For underground or under slab burial the flexible gas piping run must be encased in a sleeve of polyethylene, or other approved water resistant material. See Section 4.9, Underground Installations. Sleeved runs under concrete slabs beneath buildings must be installed as required by local codes. Most codes require venting of the sleeves under buildings to the outdoors. This can be accomplished using Pre-sleeved TracPipe PS or PS-II with available accessories.

this use when the appliance is free to move for cleaning, etc.

11. TracPipe AutoFlare

fittings have been tested by CSA International (formerly the American Gas Association Laboratories ) and are listed for use in concealed locations as defined in NFPA 54 National Fuel Gas Code, The Uniform Plumbing Code, and The International Fuel Gas Code. This facilitates installation of the key valves required for gas fireplaces in many jurisdictions. Concealed fittings are also desirable when adding tees for branch runs in series configurations and in other installation situations where locating a TracPipe fitting in an accessible location is not practical.

8. Flexible gas piping can be used in conjunction with steel pipe (black iron or galvanized) in either new construction or renovation and replacement piping installations. All TracPipe fittings terminate in standard NPT male or female pipe threads to interface with appliances, valves, unions and couplings.

9. For retrofit installations, TracPipe can be snaked through hollow wall cavities without major restoration as is typical when running rigid pipe through existing construction. The replacement or addition of gas appliances, fireplaces, and gas logs is greatly facilitated with flexible piping on reels requiring no special tooling or oily threading equipment.

10.TracPipe gas piping can be run directly

to the shut off valves of most fixed appliances without installing an appliance connector. For moveable appliances such as ranges or dryers, the use of an approved flexible appliance connector is required in most jurisdictions. TracPipe cannot be substituted as a connector for

SYSTEM CONFIGURATIONS AND SIZING

SECTION 3.1 — SYSTEM CONFIGURATIONS

There are several piping system options available to the installer using TracPipe gas piping material. This flexibility of design is one of the major benefits of CSST.

3.1A — LOW PRESSURE SYSTEMS

1. SERIES: A series layout is the most common arrangement utilized for black iron pipe. This consists of a main run with tees branching off to each appliance.

3.1B — DUAL PRESSURE SYSTEMS

Elevated pressure systems (2 psi for residential and up to 5 psi for commercial installations) are usually piped with one or more house line regulators (pounds-to-inches) followed by a manifold and runs to each of the appliances. It is possible that these runs to appliances may contain tees branching off to an additional appliance where gas loads permit.

2. PARALLEL: A parallel system consists of a central distribution manifold with branch runs to the appliances. This is usually accomplished by providing a main supply line to a manifold and installing “home runs” to each appliance location. In the parallel system shown below the pressure is not elevated above 1/2 pound and no regulator is required.

NOTE: HYBRID SYSTEMS – FLEXIBLE GAS PIPE and RIGID BLACK PIPE COMBINATIONS.

In low or medium pressure systems, it is often advantageous to use both corrugated stainless steel tubing and rigid pipe in the same system. This is the case when a larger diameter main branch is required to provide for the total appliance load in a paral-

lel system. TracPipe is certified for use in

combination with black iron pipe and copper tube gas piping systems. For additional information on Hybrid Systems see examples showing the method for sizing hybrid systems

using both TracPipe and black iron pipe

These are included in the SIZING EXAMPLES section of this manual. Refer to Section 3.2C

SECTION 3.1C — SYSTEM DESIGN

1. Prepare a sketch or layout of the gas piping system you are about to install. The information you will need is the location of each appliance, the point of delivery (location of utility meter or second stage LP regulator), appliance load demands, and possible pipe routing locations. The load demand data is usually available on the appliance manufacturer’s nameplate, or can be provided by the builder.

2. Determine local piping restrictions prior to installing flexible gas piping. The major code bodies in North America have written Corrugated Stainless Steel Tubing into the latest revisions of their mechanical codes, but local and state adoption of these codes often lags behind. CONFIRM THA THE LOCAL CODE AUTHORITY HAS ACCEPTED THE USE OF FLEXIBLE GAS PIPING. Your TracPipe distributor should be able to provide that information but confirmation by the installer should be made where there is a question.

SECTION 3.1D — SYSTEM PRESSURE CHOICES

1. NATURAL GAS-Determine the delivery pressure provided by the Local Distribution Utility where the piping will be installed.

ances manufactured for use in the US

and Canada are designed to operate up to a maximum of 14 inches water column.

c. ELEVATED PRESSURE-2 PSI -Is the

highest natural gas pressure usually supplied within residential buildings in North America. This pressure always requires the installation of a poundsto-inches house line regulator between the utility meter set and the appliances.

2. PROPANE (LP GAS)-Is typically supplied within residential buildings at 11 inches water column, set at the second stage reg-

ulator mounted outside the building. Propane can also be utilized at mediumpressure, with the use of a 13-14 inch setting. For 2 PSI Propane elevated pressure the Maxitrol regulator used is FGP-REG3P.(which is factory set at 11 inches water column.) A second stage regulator which reduces 10 psi from the tank to 2 psi must be used. (e.g. Fisher model R312E).

NOTE: TracPipe has been tested by CSA

International (formerly AGA Laboratories) for a working pressure of 125 PSI for sizes 3/8" through 1-1/4" and 25 PSI for sizes 1-1/2 & 2".

a. LOW PRESSURE-6 to 7 inches water

column-equivalent to 4 ounces or 1/4 pound is the standard pressure supplied by natural gas utilities in the USA and Canada.

b. MEDIUM PRESSURE-1/2 POUND-12

to 14 inches water column-Is available from many natural gas utilities as an enhanced pressure supply. The increase in pressure provides for reductions in

pipe size and does not require a pressure regulator. Most natural gas appli-

SECTION 3.2A — USE OF SIZING TABLES

This Chapter includes flexible gas piping sizing procedures for both low pressur e and elevated pressure systems. Every piping system introduces pressure loss to the fluid flowing within. The amount of loss depends on the piping size and the gas flow, expressed in cubic feet per hour (and converted to BTU’s). The object of the sizing exercise is to determine the smallest size piping which will introduce the allowed pressure loss or drop within the length of piping required. Sizing Tables (Capacity Charts) provide the maximum flow capacity for a given length of run for each pipe size. A different sizing table is used for each system pressure and pressure drop combination.

1. The low pressure series system (standard arrangement) is sized in the same way as a conventional low pressure black iron pipe system using TracPipe sizing tables or tables found in National Fuel Gas Code NFPA 54. This method is known as the “Branch Length Method”. Pressure drop in a low pressure system is usually limited to 1/2 inch water column over the system.

This part of the system is sized the same as a low pressure system, except that a special table N-3 is used allowing 3 inches of water column drop. These lines are typically sized for only one appliance load installed as a “home run” from the manifold.

SECTION 3.2B — SIZING EXAMPLES BRANCH LENGTH METHOD

To size each of the following systems, determine the required size for each section and outlet. To size each section of the system, determine both the total gas load for all appliances and the maximum distance (longest length) in which a particular section delivers gas.

EXAMPLE 1 LOW PRESSURE SYSTEM SERIES ARRANGEMENT

2. Elevated pressure systems incorporate two

operating pressures downstream of the utility meter set. The first pressure, set by the service regulator at the meter, is usually 2 PSI. This part of the system is sized separately and ends at the pounds-to-inches regulator. The allowable pressure loss for this part of the system must be added to the effect of the regulator to determine the available pressure at the regulator outlet. The chart in Section 4.8B shows pressure losses for maximum loads through the regulator.

3. For a 2 PSI system, the proper drop is usu-

ally 1 PSI for this part of the system; this allows for the approximate 3/4 PSI regulator drop downstream and provides the 1/4 PSI (6-7 inches w.c.) necessary for appliances. The regulator reduces the pressure from pounds to 8 inches water column.

Supply pressure 6 inches w.c. Allowable drop 0.5 inches w.c.

1. The system presented in figure 3-1 is typical of a single family installation in which there are a limited number of appliances located in one general area. The supply pressure is 6 inches water column and the allowable drop is 1/2 inch.

2. To size section A, determine the longest run from the meter that includes section A and the total gas load it must deliver:

• Meter to Furnace is 20 ft. (A+B)

parallel. The MEDIUM PRESSURE SYSTEM (1/2 PSI ) allows a higher pressure drop (6 inches Water column) than is available with low pressure systems.

• Meter to Water Heater is 25 ft. (A+C). This is the longest run.

• Determine the maximum load transported by Section A

• Furnace plus Water Heater = 100 cfh (100,000 BTU)

• Select Table N-1 “Low Pressure 6 inches- 1/2 inch w.c. drop"

• Using the longest run method, select the column showing the measured length, or the next longest length if the table does not give the exact length. Referring to table N-1 the column for 25 feet of piping shows that sizes 3/8 and 1/2 are too small and the next available size is 3/4 supplying 132 cfh.

• The correct size is 3/4".

3. To size Section B, determine the length of run from the meter to the Furnace and the load delivered:

• Length is 20 ft (A+B) and load is 65 cfh (65,000 BTU)

• Table N-1 shows that size 1/2" supplies 67 cfh

• The correct size is 1/2".

4. To size Section C, determine the length of run from the meter to the Water Heater and the load delivered:

• Length is 25 ft (A+C) and load is 35 cfh (35,000 BTU)

• Table N-1 shows that size 1/2" is required, because size 3/8" only supplies 27 cfh (27,000 BTU)

• The correct size is 1/2"

• Select table N-4 “Medium Pressure 1/2 PSI with 6 inch drop“. Table N-4 shows that 1/2" size is too small for 205 cfh at 50 ft. but 3/4" can handle 315 cfh.

• The correct size is 3/4"

3. To size SECTION B, the distance from the meter to the range is 30 ft (10+20) A+B

• Load is 55 cfh ( 55,000 BTU )

• Table N-4 shows that 3/8" size can handle 90cfh

• The correct size for section B is 3/8"

4. To size SECTION C, the distance from the meter to the water heater is 20 ft (10+10) A+C

• Load is 40 cfh ( 40,000 BTU )

• Table N-4 shows that that 3/8" size

can handle 112cfh

• The correct size for section C is 3/8"

5. To size SECTION D, the distance from the meter to the dryer is 50 ft (10+40) A+D

• Load is 30 cfh ( 30,000 BTU )

• Table N-4 shows that that 3/8" size can handle 69cfh at 50 feet

• The correct size for section D is 3/8"

6. To size SECTION E, the distance from the meter to the furnace is 20 ft (10+10) A+E

• Load is 80 cfh ( 80,000 BTU )

• Table N-4 shows that that 3/8" size can handle 112cfh at 20 feet

• The correct size for section E is 3/8"

2. To size the steel pipe trunk line, determine the longest run from the meter to any appliance and the total load. The longest run is to the fireplace.

• Meter to fireplace is 50 ft (A + D)

• Total load is 195 CFH (75 + 35 + 30 + 55) Using steel pipe Table SP-1 (page 77) following the 50 ft column down, the correct size for the steel pipe is 1".

3. To determine the size of the TracPipe run “C” to the furnace use the load through that branch (75 CFH) and calculate the length from the meter to the furnace.

• Meter to furnace is 30 ft (A + B)

• Furnace load is 75 CFH Using Table N-2A the 1.0-inch w.c. pressure drop chart for TracPipe. Follow the 30 ft column down, the correct size for the furnace branch line “C” is 1/2".

4. To determine the size of the TracPipe run “B” to the water heater use the load through that branch (35 CFH) and calculate the length from the meter to the water heater.

• Meter to water heater is 30 ft (A + C)

• Water heater load is 35 CFH Using Table N-2A the 1.0-inch w.c. pressure drop chart for TracPipe. Follow the 30 ft column down, the correct size for the water heater branch line “B” is 1/2".

5. To determine the size of the TracPipe run “D” to the fireplace use the load through that branch (30 CFH) and calculate the length from the meter to the fireplace.

• Meter to fireplace is 50 ft (A + D)

• Fireplace load is 30 CFH Using Table N-2A the 1.0-inch w.c. pressure drop chart for TracPipe. Follow the 50 ft column down, the correct size for the fireplace branch line “D” is 1/2".

6. To determine the size of the TracPipe run “E” to the range use the load through that branch (30 CFH) and calculate the length from the meter to the range.

• Meter to range is 45 ft (A + E)

• Range load is 55 CFH Using Table N-2A the 1.0-inch w.c. pressure drop chart for TracPipe. Follow the 50 ft column down, the correct size for the range branch line “D” is 1/2".

SECTION 3.2D — ALTERNATE SIZING METHOD: SUM OF PRESSURE LOSS CALCULATIONS

1. In addition to the longest run sizing method, there is another approach to pipe sizing, which yields results closer to the actual friction loss results (obtained from testing) for each section of an installed gas piping system. This engineered approach “Sum of Pressure Loss Calculations” avoids the simplified, conservative approximations of the longest run method. Mechanical engineers who design piping systems understand that placing a building’s entire load (theoretically) at the farthest equipment outlet is not only inaccurate but will often yield pipe sizes which are larger than necessary . The longest run method was devised at a time when gas utilities could not always guarantee a constant pressure at every meter during times of high demands; it is a conservative approach and, although it is the customary sizing approach in North America, other engineered calculations are permitted by most codes.

2. Pressure Loss Calculations which sum up friction losses in each section of a gas piping system can provide a system design with more accurate and possibly smaller piping diameters than the traditional longest run method. These calculations utilize pressure loss charts for each size of CSST, which have been developed from actual test results. The maximum flow capacity is predicted with more precision than with the longest run method. The Sum of Pressure Loss method is described below with tables providing pressure loss per foot based upon the total load supplied by that length of pipe with all appliances operating.

3. The system designer has simply to determine the load and the length for each run. A tentative size is chosen and pressure loss in that leg is determined by multiplying the loss per foot (inches w.c. from the chart) by the length. Starting at the meter and working outward the pressure loss for each leg is then summed up until the farthest appliance is reached. The total calculated loss is then compared with the allowable loss, which must not be exceeded from the meter to the farthest appliance. The allowable pressure loss for each system is the responsibility of the system designer, based on model codes and on the available pressure at the meter set (or second stage regulator) and the pressure required for each appliance (usually found on the manufacturer's data plate.) Current language in many model codes states: The allowable loss under maximum probable flow conditions, from the point of delivery to the inlet connection of the appliance, shall be such that the supply pressure at the appliance is greater that the "minimum inlet pressure" as stated on the appliance manufacturers data plate. If the initial proposed design calculation yields a total pressure loss, which is higher than allowed, simply go back and calculate again with larger sizes, starting from the meter.

1. The system presented in figur e 3-8 is similar to that in 3-1, a single-family installation with the addition of one more appliance, a dryer. The supply pressure is 6 inches water column and the allowable pressure drop is 1/2 inch.

2. To size section A, calculate the load carried by that section:

•Furnace plus Water Heater plus Dryer = 135 CFH (135,000 BTU) Using Table PD-1 find pressure loss at 135 MBTU load through 3/4"TracPipe Average of .019 and .022 is .021. Drop per foot is

0.021; multiply by length 10 feet = 0.21 drop

3. To size section B find the drop per foot for the load carried by that section: 65 CFH (MBTU)

Using Table PD-1 find pressure loss at 65 MBTU through 1/2" TracPipe Use the average of loss between 60 and 70 MBTU: Average of .019 and .027 is .023 ; Drop per foot is 0.023 Multiply by length 10 feet = 0.23 drop Sum pressure loss meter to Furnace 0.21 + 0.23 = .44 inches w.c This leg is sized properly at 1/2" because sum of loss is less than .5 in. w.c.

4. To size section C1 find the drop per foot for the load carried by that section:

70 CFH (MBTU) Using Table PD-1 find pressure loss at 70 MBTU load through 1/2"

TracPipe

Drop per foot is .027; length is 5 ft; 5 X .027 is .135

6. To size section D find the drop per foot for the load carried by that section: 35 CFH (MBTU)

Using Table PD-1 find pressure loss at 35 MBTU through 1/2" TracPipe Drop per foot is .006 (see number 4 above); Multiply by length 15 feet = .09 Sum pressure loss to dryer 0.21 + 0.135 + .09 = .435 inches w.c. This leg is sized properly at 1/2" because sum of loss is less than .5 in. w.c.

The sum of pressure loss method allows the addition of an appliance without increasing trunk line size.

EXAMPLE 9 LOW PRESSURE HYBRID SYSTEM (Steel Pipe and TracPipe Combination) SERIES ARRANGEMENT USING SUM OF PRESSURE LOSS METHOD

2. Begin by using pipe sizes determined in Example 6 and determine if these are correct with this method. It is possible that smaller pipe sizes may be sufficient; this will be determined by calculating the sum of pressure losses from the meter to each appliance. To use this method a tentative size will be assigned to each run and this size will be confirmed or revised by the calculation. The sum total loss of a run from the meter to the appliance cannot exceed the allowable pressure loss.

3. To determine pressure loss through section A (steel pipe trunk), use the load through that section (230 CFH) and find pressure loss per foot from the steel pipe Schedule 40 Pressure Drop Curves Graph Table SP-1. The 11/4 inch pipe diameter line intersects the 230 CFH line at a pressure drop of .18 inches w.c. per 100 feet of length. Multiply the length: 40 feet by the loss per foot: 0.0018. The pressure loss for this section is 0.072.

4. To determine pressure loss through section B we use the load through that section (175 CFH). Find pressure loss for 1" size from the steel pipe graph in Table SP-1

- 0.6 per 100 feet. Multiply the length: 20 feet by the loss per foot: 0.006. The pressure loss for this section is 0.12.

5. To determine pressure loss through section C1 we use the load through that section (105 CFH). Find pressure loss for 1" size from the steel pipe graph - 0.2 per 100 feet. Multiply the length: 5 feet by the loss per foot: 0.002. The pressure loss for this section is 0.01.

6. To determine pressure loss through section C2 we use the load through that section (70 CFH). Find pressure loss for 3/4" size from the steel pipe graph - 0.38 per 100 feet. Multiply the length: 5 feet by the loss per foot: 0.0038. The pressure loss for this section is 0.019.

7. To determine pressure loss through section D we use the load through that section (30 CFH). Find pressure loss for 1/2" size from the steel pipe graph - 0.31 per 100 feet. Multiply the length: 10 feet by the loss per foot: 0.0031. The pressure loss for this section is 0.031.

8. To determine pressure loss through section E (TracPipe drop to the range), use the load through that section (55 CFH) and find pressure loss from Table PD-1 Pressure Drop per Foot for TracPipe. Trying the 3/4 inch column we find .004 inches per foot length (there is no 55 CFH load listed, so we use 60 CFH). Multiply the length: 30 feet by the loss per foot .004. The pressure loss for this section is

0.12. Add the loss of section A to the loss of section E for total loss from the meter to range. 0.072 + 0.12 = 0.192. Since this is less than the 0.5 allowable drop the correct size for section E is 3/4".

9. To determine pressure loss through section F (TracPipe drop to the furnace), use the load (70 CFH) and find pressure loss from Table PD-1. In the 3/4" column we find 0.005. Multiply the length: 30 feet by 0.005. The pressure loss for this section is 0.15.

Add the loss of sections A + B to the loss of section F for total loss from meter to furnace. 0.072 + 0.12 + 0.15 = 0.342. The correct size for section F is 3/4".

10. To determine pressure loss through section G (TracPipe drop to the water heater), use the load (40 CFH) and find pressure loss from Table PD-1. In the 1/2" column we find 0.008. Multiply the length: 25 feet by 0.008. The pressure loss for this section is 0.20. Add the loss of sections A + B + C1 + C2 to the loss of section G for total loss from meter to furnace. 0.072 +

0.12 + 0.01 + 0.019 + 0.20 = 0.421. The correct size for section G is 1/2".

11. To determine pressure loss through section H (TracPipe drop to the fireplace), use the load (30 CFH) and find pressure loss from Table PD-1. In the 1/2" column we find 0.004. Multiply the length: 40 feet by 0.004. The pressure loss for this section is 0.16. Add the loss of sections A + B + C1 + C2 + D to the loss of section H for total loss from meter to furnace. 0.072 +

0.12 + 0.01 + 0.019 + 0.031 + 0.16 =

0.412. The correct size for section H is 1/2".

2. To determine pressure loss through section I (TracPipe drop to the dryer), use the load (35 CFH) and find pressure loss from Table PD-1. In the

0.006. Multiply the length: 30 feet by

0.006. The pressure loss for this section is

0.18. Add the loss of sections A + B + C1 to the loss of section I for total loss from meter to dryer. 0.072 + 0.12 + 0.01 + 0.18 = 0.382. The correct size for section I is 1/2"

. Using the Sum of Pressure Loss Method we calculate that three of the five TracPipe sections (when compared with the longest length method) can utilize reduced sizes to deliver the necessary load with a pressure loss equal to or less than the allowable 0.5 inches water column. This enables the installer to use TracPipe on all but the furnace and range drops, which remain

SECTION 3.3 — GASBREAKER

EXCESS FLOW DEVICES FOR CSST AND STEEL PIPE GAS SYSTEMS

GasBreaker excess flow devices protect against residential and commercial gas line breaks. GasBreakers work in conjunction with TracPipe and other brands of CSST at the gas meter as well as at the appliance manifold. GasBreakers should be connected directly to the manifold at the point between the manifold and the appliance gas lines, which will offer increased safety for the building occupants. The charts used to size CSST systems below are for use with TracPipe flexible gas piping only. (For other CSST brands, size the piping by assuming that the load for that section of pipe is the maximum load of the excess flow device chosen).

1. GASBREAKER LOW PRESSURE

EXCESS FLOW DEVICES FOR PROPANE AND NATURAL GAS SERVICE. An excess flow device is a pro-

tective device to help control the discharge of fuel gas in the event of a complete breakage of pipe lines or flex connector rupture. Excess Flow Devices have been of help in limiting gas loss in many incidents involving breakage of piping. Thus, they do provide a useful safety function in gas systems. This section explains

what protection Excess Flow Devices can offer, points out conditions which can interfere with that protection, and offers suggestions for effective Excess Flow Device installation.

2. INSTALLATION OF GASBREAKER DEVICES ON GAS METERS. The GasBreaker device can be installed downstream of the gas company meter and bypass tee outlet using standard pipe fittings and procedures. GasBreaker Meter Devices must be installed within 5 degrees of the vertical position with the flow arrow pointing upwar

d in the direction of flow.

3. INSTALLATION OF GASBREAKER APPLIANCE DEVICES. GasBreaker devices should be connected directly to the manifold at the point between the manifold and the gas appliance lines. If there is no manifold, the devices could be located at the tee or fitting where the appliance drop attaches to the trunk line. All GasBreaker devices except series 120 appliance device must be installed in the vertical position (within 5 degrees) with the flow arrow pointing upward in the direction of flow. The series 120 appliance device can be installed in a vertical or horizontal position with the flow arrow pointing in the direction of flow.

SECTION 3.4 — SIZING INSTRUCTIONS FOR GASBREAKER DEVICES USED WITH CSST/TRACPIPE SYSTEMS

SECTION 3.4A — METER DEVICES (SERIES FGP-GB300, FGP-GB400, FGP-GB600)

1. Choose the GasBreaker Meter Device from Table 3.1 based on the total capacity of the gas piping system served by that meter.

2. Using the appropriate GasBr eaker Capacity Chart “Table N-1GB GasBreaker Low Pressure” or “Table N-5GB GasBreaker (2psi system)” based upon system pressure; determine the size of CSST, which will supply the necessary total capacity of that meter. This size of CSST is designed to allow the GasBreaker device to act as a safety shut-off device in the event of a complete breakage of the main downstream trunk line piping. Note: GasBreakers installed at the meter are not designed to protect against breakage of piping downstream that has been reduced from the initial size or appliance branch piping.

SECTION 3.4B — APPLIANCE DEVICES (SERIES FGP-GB090, FGP-GB120, FGP-GB150)

2. Series System Low Pressure a. When there is no manifold, the devices

should be located at the tee or fitting where the appliance drop attaches to the trunk line. If this is a concealed location, follow local codes.

b. Choose the appropriate size device

(“Max. Load Capacity (BTU/hr)” column) for each appliance from Table 3.1. Select a device with sufficient capacity to supply the appliance(s) connected to that drop.

c. Using GasBreaker Capacity Chart “Table

N-1GB GasBreaker Low Pressure” determine size of TracPipe CSST which will carry the required load for the distance from the meter to the appliance(s). This size of CSST is designed to allow the GasBreaker device to act as a safety shut-off device in the event of a complete downstream breakage of pipe lines or flex connector rupture.

SECTION 3.4C — SIZING INSTRUCTIONS FOR GASBREAKER DEVICES WITH STEEL PIPE SYSTEMS

1. Choose the GasBreaker Device (Appliance

or Meter) from Table 3.1, based upon either the capacity of the appliance or the total capacity of the gas piping system served by the meter.

N-3GB GasBreaker Dual Pressure System” determine size of TracPipe CSST which will carry the required load for the distance from the manifold to the appliance(s). This size of CSST is designed to allow the GasBreaker device to act as a safety shut-off device in the event of a complete breakage of downstream pipe lines or flex connector rupture.

2. Using GasBreaker Capacity Chart “Table SP-1GB GasBreaker Steel Pipe Low Pressure” determine the size of CSST, which will supply the necessary capacity of that appliance or meter. This size of CSST will allow the GasBreaker device to act as a safety shut-off device in the event of a complete downstream breakage of pipe lines or flex connector rupture.

Gas Breaker’s published limitations, based upon black pipe sizing (Pipe break open to atmosphere) are:

Series 300: For up to 60' of 3/4" and 190'

of 1" pipe.

INSTALLATION PRACTICES

SECTION 4.1 — GENERAL INSTALLATION PRACTICES

Precautions must be taken to ensure that any exposed flexible piping is not damaged or abused during building construction. All system hardware should be stored in a secure, dry location prior to installation.

1. The piping system is for use with fuel gas at operating pressures up to 25 PSI (USA and Canada restriction). TracPipe gas piping (3/8" up to 1-1/4" sizes) has been tested and is approved for pressures up to 125 PSI, and may ONLY be used at this pressure with the consent of the local gas utility and code authority. 1-1/2" & 2" size TracPipe gas piping has been tested and are approved for pressures up to 25 PSI. Pressure tests up to 125 PSI are permitted on sizes up to 1-1/4".

2. Only components provided by OMEGA FLEX or specified as part of the TracPipe piping system are to be used in the installation.

DO NOT USE TRACPIPE TUBING OR FITTINGS WITH TUBING OR FITTINGS OF ANY OTHER MANUFACTURER. INTERMIXING OF CSST TUBING OR FITTING COMPONENTS BETWEEN CSST MANUFACTURERS IS PROHIBITED. CONNECTIONS BETWEEN TWO DIFFERENT BRANDS OF CSST MAY

BE ACCOMPLISHED USING STANDARD MALLEABLE IRON FITTINGS.

3. Ends of the piping are to be temporarily capped, plugged or taped closed prior to installation and pulling through structure to prevent entrance of dirt, or other debris.

4. Contact with sharp objects or harmful substances is to be avoided. Contact with

any chemicals containing chlorides or ammonia must be followed by thorough rinse and wipe dry.Typical chloride based

chemicals include fluxes used for soldering copper tubes and acid based cleaners such as muriatic acid used for cleaning brickwork. Use only non-cor

detection fluids.

5. BENDING TRACPIPE

Undue stress or strain on the tubing or fittings is to be avoided. Bending flexible gas piping is one feature which contributes to the speed of installation. The recommended bend radius for general routing of tubing is listed in Table 4-1. Multiple tight bends can restrict the gas flow and increase pressure drop. The tightest bend allowed for each size of TracPipe is shown in the chart below. Typical locations

requiring tight bends are termination mount installations in hollow stud walls.

6. SUPPORTING TRACPIPE Piping shall be supported in a workmanlike manner with pipe straps, bands, brackets or hangers suitable for the size and weight of the piping. TracPipe which passes over or through a structural member is considered to be supported by that member.

6A. VERTICAL RUNS

Spacing of supports is not to exceed 10 feet, requiring hangers only where the height of each floor is greater than 10 feet.

It is acceptable to use standard pipe straps or tubing clips available in metal or plastic materials, OMEGAFLEX has found that the use of two-attachment point plastic clips or metal EMT pipe straps is advisable. Some plastic clips, especially the “Jclips” designed to support plastic tubing are susceptible to breakage upon subsequent handling by other trades.

SECTION 4.2

HOW TO ASSEMBLE TracPipe AUTO-FLARE FITTINGS

INSTRUCTIONS for making Fitting Connections to Flexible Gas Piping

1. CUT-TO-LENGTH: Determine proper length. Cut through plastic jacket and stainless tube using a tube cutter with a sharp wheel. Cut must be centered between two corrugations. Use full circular strokes in one direction and tighten roller pressure slightly (a quarter turn) after each revolution. DO NOT OVERTIGHTEN ROLLER, which may flatten tube.

NOTE: Due to the large diameter and depth of corrugation on sizes over 1", tubing must be cut with a standard tubing cutter RIDGID

using a TracPipe cutting wheel no. FGP-E-5272

(P/N E-5272 or equal). CAUTION: Use of a small cutting wheel may flatten the first corrugation and make cutting and/or sealing of fittings difficult.

152 or equal

2. STRIP JACKET: Using a utility knife, strip back the jacket approximately one inch to allow assembly of fittings. Caution: For your

personnal safety--Knife blade and cut tube ends are both sharp. Use care when cutting the jacket and handling the tube.

INSTRUCTIONS for making Fitting Connections to Flexible Gas Piping

(Continued)

3. INSTALL FITTING NUT: Slide nut over cut end: place two split-rings into the first corrugation next to the tube cut. Slide nut forward to trap the rings.

4. WRENCH FITTING: Place the adapter into the nut and engage threads. Note that the AutoFlare leak tight seat on the stainless tubing as you tighten the fitting. (The piloting feature of the adapter will not always enter the bore of the tubing before the tightening operation, but will center the fitting when tightened). Using appropriate wrenches, tighten the fitting until adapter bottoms and the resistance to wrenching increases greatly. The flare has now been created on the tubing end.

CAUTION- DO NOT USE ANY THREAD SEALANTS FOR THIS CONNECTION. SEALANTS ARE TO BE USED ON THE PIPE THREAD ONLY.

5. FINAL TORQUE: Tighten nut and adapter to the torque values shown in Table 4-3. For field installations use the following method: Tighten nut and adaptor as though you were making up a flared tubing joint. Note relation between hex flats at this point and continue to tighten for two additional hex flats (one-third turn) to obtain required torque and final leak-tight seal.

AutoFlare® (Patented) – The Fitting is the Flaring Tool

SECTION 4.2A — TROUBLE SHOOTING FITTING CONNECTIONS

1. The tubing cut is the critical step in the fitup procedure. Always cut in a straight section of piping, rather than an area you have bent. Use light roller pressure applied on every revolution to cut tube evenly around its surface. Remember that this tube has a thinner wall than the copper tube you are accustomed to cutting. A sharp blade is very important, and it will be helpful to reserve one cutter for stainless steel only.

2. If the fitting connection cannot be made to seal upon applying torque per the instructions in Section 4.2, continue to tighten an additional quarter to a half turn. If leakage continues, do not continue to apply torque. Disassemble the fitting and inspect the sealing surfaces. The most likely cause of leakage is foreign material on the sealing surfaces. Wipe both fitting and tubing flare with a clean cloth. Inspect the formed flare on the tubing end, which should appear round when compared with the split ring washers and the nut in place. If any deformation is

noted, the tubing can be recut and the fitting re-attached. The patented Autoflare fitting has an insert which is self piloting and does not require special tooling to make a

leak proof fitting.

3. REASSEMBLY - When reattaching the AutoFlare fitting, it is only necessary to reinsert the split rings into the space between the first two corrugations and to pull the nut back over the rings into position. The adapter can then be conveniently re-threaded into the nut and torqued as before. If the nut cannot be pulled into place, examine the split-rings, which may have been “coined” by the first torque operation. If this is the case, simply reverse the split-rings positioning to align with the nut and continue the assembly pr

ocess.

three times, or if the nut cannot be pulled over the rings in any position, then the split-rings

must be replaced. Packets of spare split-

rings are available (P/N FGP-RING-SIZE) and the remaining fitting parts can be reused.

If the fitting is reattached more than

SECTION 4.3 — ROUTING

Depending on local building codes and construction practice, Flexible gas piping can be routed:

1. Beneath floor joists, thr ing joists, along side of floor and ceiling joists. This is the typical location for residences and commercial buildings with basements and for multi-floor systems.

2. Inside hollow interior wall cavities. the preferred location for vertical sections of piping, rather than horizontal sections.

3. Thr

4. Clearance holes for routing the piping

ough approved conduit under ground or under building slabs. When piping runs are located below grade or under a concrete slab, the TracPipe shall be routed within a non-metallic water-tight conduit. No tubing joints are permitted within the conduit. Gas piping runs beneath building slabs must be both sleeved and vented to the atmosphere. See Underground Installations Section 4.9 for underground use of TracPipe PS and TracPipePS-II. TracPipe PS and TracPipePS-II meet code requirements for underground and under building slab installation.

through studs, joists, plates etc. shall have a diameter at least 1/2 inch larger than the outside diameter of the piping. When a structural member must be drilled, conformance to building codes must be followed. No structural member shall be seriously weakened or impaired by cutting, notching or otherwise altering the member. Minimum drill hole sizes are listed in Table 4-4.

5. METAL STUDS For installations involving horizontal runs through galvanized steel studs, the use of plastic grommets supplied by the stud manufacturer is recommended. The use of these grommets will reduce the likelihood of damage to the tubing non-metallic jacket.

SECTION 4.3A — CONCEALED LOCATIONS FOR FITTINGS — GENERAL PROVISIONS

The AutoFlare®mechanical attachment fittings have been tested and are listed per the requirements of ANSI LC1 and CSA 6.26 Standard (USA and CANADA) This specification provides test requirements which certify fittings for concealed installations and connections to appliances where concealing the fittings is the only practical alternative.

These guidelines address some of the known situations which may require the use of a concealed fitting. While accessibility of fittings may be desirable there are often situations where concealing the fittings is the only practical option. This guide cannot address all applications of concealed fittings but provides instead typical instructions to demonstrate the principles which apply to fittings listed for installation in concealed locations (Ref National Fuel Gas Code NFPA54 Chapter 6).

EXCLUSIONS:

1. Manifold Stations (for 2 PSI systems) which include the multiport manifold, shut off valve, and pressure regulator shall not be installed in concealed locations regardless of the qualifications of tubing fittings.

NEW INSTALLATIONS:

1. CSST may be connected to steel piping

systems through threaded pipe connections. This can be a stub-out to an appliance connection or outdoors to a meter, etc.

2. Flexible piping connections to fireplace “key valves” can be located in a concealed location, when accessibility is not readily

provided. See Illustrations 1 & 2 for typical key valve mountings.

Flexible piping fittings originally installed in accessible ceiling locations can be concealed at a later date in the event that a ceiling is installed. Precautions shall be taken to ensure that the newly concealed piping and fittings are adequately protected from accidental puncture in accordance with the instructions in this guideline.

2. Extensions to existing tubing runs-A tubing run can be modified to permit an extension to another appliance location provided there is sufficient capacity to supply both appliances at the same time. If an accessible location for the modification is not available, the existing tubing run can be modified with a tee fitting, resulting in a concealed fitting.

3. Repairs to existing tubing runs-Damaged tubing

runs shall be repaired in accordance with instructions in this guide (Section 5.2). The repair can result in a line splice which may ultimately be located in a concealed location.

SECTION 4.3B — OUTDOOR INSTALLATION ISSUES

The following section provides instructions for the use of TracPipe in systems in which portions of the piping are exposed to the outdoors as required to make connections to gas meters or appliances which are attached to, mounted on, or located in close proximity to the building structure. ANSI/IAS LCICSA 6-26-1997 contains test requirements determining suitability for exposure of CSST piping systems to outdoor environments. T racPipe is certified to this standard and is fully qualified for outdoor installations. The TracPipe yellow jacket contains UV inhibiters to retard jacket degradation when exposed to long periods of sunlight.

1. When installed outdoors, the plastic jacketing shall remain intact as much as practical for the given installation. Any portions of exposed stainless steel shall be wrapped with self bonding silicone tape sealing the fitting connection to prevent later corrosive attack by acid wash or chloride based compounds. (See Figures 4-3A & 4-3B)

2. When TracPipe is installed in a swimming pool mechanical room or exposed to a corrosive environment which may be harmful to the tubing, all exposed portions of the stainless steel tubing shall be wrapped with selfbonding tape. (See Figures 4-3A & 4-3B)

3. When installed along the side of a structure (between the ground and a height of 6 feet) in an exposed condition, the TracPipe shall be installed in a location which will not subject the piping to mechanical damage or be protected inside a conduit.

NOTE: For support and protection, OmegaFlex recommends that outside runs along the side of a building be clipped securely to the wall or other structural component.

4. TracPipe shall not be buried directly in the ground or embedded in concrete unless it is sleeved inside of a non-metallic (PVC or TracPipe PS or PS-II Polyethylene) water tight conduit. The conduit shall be sealed at any exposed end to prevent water from entering. See instructions for underground installations Section 4.9.

5. When installed underneath mobile homes or in crawl spaces, TracPipe shall be installed in accordance with these standard outdoor instructions.

SECTION 4.4 — PROTECTION

The flexible gas piping must be adequately protected from puncture, shear, crush or other physical damage threats. The tubing shall be protected at points of support and when passing through structural members such as studs, joists and plates in accordance with this section. PROTECTION IS REQUIRED WHENEVER THE TUBING IS CONCEALED, RESTRAINED, AND WITHIN 3 INCHES OF A POTENTIAL THREAT. If the tubing requires protection, the following measures should be taken.

SECTION 4.4A — STRIKER PLATE REQUIREMENTS

1. Install shielding devices i.e. striker plates to protect the tubing from penetration by drill bits, nails, screws, etc. in those areas where the tubing will be concealed and will not be free to move to avoid such puncture threats.

NOTE: Only CSA approved hardened striker plates listed for CSST systems may be used.

a. At support points and points of penetra-

tion less than 2 inches away from any edge of a stud, joist, plate, etc. shielding is required at the area of support and within 5 inches of each side (if appropriate). Use a half striker or a full striker plate in these locations. (Figure 4-4)

d. When tubing is routed horizontally

between studs, install quarter striker plates at each stud and floppy galvanized steel conduit (spiral metal hose) along the entire length.

e. Schedule 40 steel pipe has been tested by

CSA International and found acceptable for puncture protection. Steel pipe can be used where standard striker plates cannot reasonably be installed. Examples of this type of use

2. The best protection is to install the tubing in those out of the way areas where testing has shown no protection is necessary, for example:

a. Where the tubing is supported more

than 3 inches from any outside edge of a stud, joist, plate, etc. or wall surface. (Figure 4-6)

b. Where any non-restrained tubing can be

displaced from the direction of potential penetration at least 3 inches.

Figure 4-6

No Shielding Requirement at Support Area when Points of

Penetration are greater than 3 inches from any Edge of a Stud,

Joist, Plate, etc.

c. When tubing is supported under the

joists in basements or crawl spaces and is not concealed by wallboard or ceilings.

3. TracPipe with its specially formulated yel- low polyethylene jacket has been tested to the flame spread and smoke density requirements of ASTM E84 and meets ANSI LC-1 limits imposed for this criteria.

NOTE: For TracPipe tubing version with Black

outer jacket, the installer shall meet local building codes with respect to flame spread and smoke density regulations for non-metallic materials. Omegaflex recommends either removing the black jacket or transitioning to the standard yellow jacketed product when passing through areas such as drop ceiling return plenums.

4. For through-penetration fire stop instructions refer to the UL classification requirements shown in appendix A. When passing through a fire stop (2hr. wall) the YELLOW jacket does not have to be r

emoved. Seal between building and TracPipe with an approved 3M type CP-25 or equivalent caulk. The BLACK jacket shall be removed for 2 ft. on each side of the penetration when passing through a fire stop.

5. TracPipe has thru-penetration UL Classifications for 1,2,3 and 4 hour requirements depending on materials and type of construction. See Appendix A.

SECTION 4.5 — METER CONNECTIONS

1. Meters which depend on the service and

house piping for support shall not be directly connected to the flexible piping. Instead, use a meter termination fitting or termination mount fitting with steel pipe for the outdoor portion of the connection. For mounting of meters, all fastener locations should be used when installing the flange or mounting plate. (Figure 4-8)

2. Meters which are independently supported

with a bracket can be directly connected outdoors with TracPipe. If practical, direct con- nections shall include a 3 to 6 inch additional length of tubing to accommodate differential settling and meter movement. No mechanical protection of the tubing is required for outdoor connections. PRIOR TO INSTALLING TracPipe DIRECTLY TO A METER, ENSURE THAT THE LOCAL UTILITY ALLOWS THIS PRACTICE as some utilities have regulations specifying meter attachments. Any exposed sections of stainless steel piping must be wrapped with a silicone self-bonding tape.This is especially important with masonry construction. (Figure 4-9) A PVC Sleeve is recommended for TracPipe penetration of both masonry and wood frame construction.

SECTION 4.6 — APPLIANCE CONNECTIONS

A listed termination outlet (termination mount or flange fitting) shall be installed and secured to the structure at all floor & hollow wall piping outlets used for moveable appliances and quick disconnect devices. The termination outlets are designed to simplify the installation of gas connections for movable appliances and minimize the need for concealed fittings. The flange fitting or plate shall be securely fastened in place during rough-in. It may be attached to a brace spanning between studs for a wall location, or directly to the floor. (Figure 4-11) The flange may also be mounted with a flange L- bracket, which is nailed or screwed to the stud. When a moveable appliance is in a location where a termination outlet cannot be readily installed through the structure, the TracPipe can be tran- sitioned to black pipe at a suitable location and

the black iron pipe fastened to the block walls or concrete. Another option is to use termination mounting bracket fastened to the block wall and make the drop with TracPipe. Final connection is with a flexible appliance connector.

1. MOVABLE APPLIANCE CONNECTIONS

(SUCH AS RANGES AND DRYERS) SHALL BE MADE USING APPROVED FLEXIBLE APPLIANCE CONNECTORS. (Figure 4-12) See also recessed wall box

2. FIXED APPLIANCE CONNECTIONS MAY BE DIRECTLY CONNECTED TO THE FLEXIBLE GAS PIPING SYSTEMS (in most jurisdictions). When the fixed appliance is located in a secure, dedicated space, such as a basement, attic, garage or utility closet, the flexible piping may be directly connected to the appliance shut-off valve without installation of a flange fitting or flexible appliance connector.

Table 4-2, and raised above the roof a distance determined by local code/practice.

1. Gas appliances mounted on concrete pads or blocks, such as gas air conditioners heat pumps, pool heaters and NGV refueling stations, shall be connected to the TracPipe system at a termination fit- ting using either rigid pipe or an approved outdoor appliance connector. Direct connection of TracPipe to pad mounted equipment is permitted when the CSST is securely supported and located where it will be protected from physical damage. Follow local and state codes.

3. TracPipe may be supported with strut/channel running from block to block beneath the flexible gas pipe. Galvanized shallow channel (13/16") with splice plates at joints and bends provides a secure, damage resistant “track”. With metallic strut support, blocks can be reduced to every 8 feet. The TracPipe should be firm- ly attached to each block with metallic clamps designed for the strut or appropriate fastening mechanism. (See Figure 4-

Section 4.6C — FIREPLACE INSTALLATIONS

1. TracPipe may be used to deliver gas directly to the valve for a gas fireplace. This is approved for decorative and heat generating fireplaces and for gas logs used in masonry and pre-fabricated fireplaces. DO NOT use TracPipe to con- nect gas log lighters or gas wands for use in all-fuel (woodburning) fireplaces.

2. Most gas fireplaces and gas logs (Refer to ANSI Z24.60) fall into the definition of fixed appliances which can be directly connected to TracPipe without the use of a flange mount fitting. The attachment is generally to the shut-off valve which may be located in the control area beneath the burner unit or at the side of the log set. TracPipe can be run into the lower control area for attachment without removal of the polyethylene jacket. In vented fireplaces, attachment to gas logs is best accomplished by removal of the jacket inside the fire box. This precludes direct flame contact with the polyethylene jacket. Stainless Steel melting temperatures

(2000

F) are consistent with black iron.

4. When it is necessary to install TracPipe through sheet metal enclosures, such as those commonly used in decorative gas fireplaces, the manufacturer’s recommendation is to leave the protective yellow polyethylene jacket in place through the sheet metal penetration. The TracPipe should be clipped to the building structure at a suitable location outside the fireplace to limit the amount of motion after installation. If additional protection is required, such as an installation with a source of vibration (fan, etc.) which may cause abrasion, then a short piece of floppy conduit or PVC pipe may be used between the jacket and the enclosure.

5. In masonry fireplace installations of decorative gas appliances (log sets) it is recommended to leave the polyethylene jacket in place throughout the masonry penetration providing a non-metallic sleeve for the flexible stainless steel. Caulking can then take place between the jacket and the penetration at interior and/or exterior locations. Remove the jacket inside the firebox. If additional protection is required, the TracPipe may be sleeved using PVC pipe in addition to the included jacket.

3. For gas log lighter installations in all-fuel fireplaces, the TracPipe run MUST be terminated at the key valve or another location outside the fireplace. The final attachment should be made using black iron pipe.

SECTION 4.7 — MANIFOLD & REGULATOR STATION

The use of a central manifold and regulator station is recommended for elevated pressure systems which are typically installed in a parallel arrangement to take advantage of the capacity of the regulator, which is sufficient for several appliances. Manifolds are available with the TracPipe system, or the use of black iron pipe and tee fabricated manifolds is permitted with this system. The manifold/regulator station should be located nearby the largest gas consuming appliances, typically the furnace or boiler and the water heater in order to allow short runs to these units.

manifold

The manifold station MUST be located in an accessible location because of the shut-off valve(s) and regulator it contains. The manifold station may be contained in an enclosure box called a gas load center. Optional gas shut-off valves may be mounted on the manifold for each appliance run.

Gas Load Center

SECTION 4.8— REGULATORS AND ELEVATED PRESSURE SYSTEMS

A tubing system used at gas pressures exceeding 1/2 PSI but serving appliances rated for 1/2 PSI maximum, shall contain a pounds-to-inches regulator to limit the downstream pressure to no more than 1/2 PSI. The regulator must incorporate a lock-up feature limiting downstream pressure to 1/2 PSI under no flow conditions. The regulator shall comply with the applicable provisions of ANSI Z21.18 or CAN 1-6.3-M82.-ANSI Z21.80

Regulators used to reduce elevated system pressures for use by appliances must also conform to the following:

1. Must be sized to supply the required appliance load.(see chart below)

2. Must be equipped with an acceptable vent limiting device, supplied by the manufacturer, or be capable of being vented to the outdoors. The vent-limiting device can be used when the regulator is installed in a ventilated area. OMEGAFLEX ships all REG-3 & REG-5A regulators with vent-limiters installed. Vent-limiters are not available for REG-7 series regulators.

TIONS. WHEN A VENT-LIMITER IS USED THE REGULATOR MUST BE MOUNTED IN AN UPRIGHT POSITION. INSTALL THE REGULATOR PROPERLY WITH GAS FLOWING AS INDICATED BY THE ARROW ON THE CASTING.

4. Must be installed in a fully accessible area with an approved shut off valve ahead of regulator. An optional union will enable removal of the regulator if the location does not otherwise permit removal for servicing. The ability of the autoflare fitting to allow dissasembly and reattachment provides for regulator removal in most instances.

5. Line regulators do not vent gas under normal

operating conditions. Any regulator found to be venting gas should be replaced immediately. Vent-limiters are required to limit venting in the event of a diaphram failure, within the regulator, to limits identical to those imposed on a gas appliance control valve.

6. An area is considered to be ventilated if the

combustion, ventilation or dilution air is obtained from the occupied areas of the building, or from outside, or from both, into the common areas of the appliance locations. Reference applicable codebook for details.

7. For outdoor installations remove the vent limiter and mount regulator with the vent outlet pointing down to prevent the entrance of water. A plastic cap FGP-CAP-3 is available for outdoor installations permitting regulator to be mounted in an upright position.

NOTE: For outdoor venting, the line must be at least the same size as the regulator vent connection, and cannot exceed a length of 30 feet. The vent shall be designed to prevent entry of water, insects or other foreign materials that could cause blockage of the line. DO NOT VENT TO APPLIANCE FLUE OR BUILDING EXHAUST SYSTEM. DO NOT VENT TO PILOT LIGHT.

3. MUST BE INSTALLED IN ACCORDANCE WITH MANUFACTURERS INSTRUC-

SECTION 4.8A REGULATOR ADJUSTMENTS

1. Regulators can be adjusted to deliver different outlet pressures within a limited range. The range is determined by the spring installed.

2. Adjustment can be accomplished by first

removing the regulator seal cap to expose the adjusting screw . Turning the screw clock-

wise will increase outlet pressure, turning it counter-clockwise will decrease pressure.

3. If spring adjustment will not produce desired outlet pressure, check to make sure supply pressure is at least equal to desired outlet pressure plus pressure drop of the regulator. If supply pressure is ade-

quate, consult factory if adjustment still can not be made. Do not continue to turn regulator adjusting screw clockwise if outlet pressure readings do not continue to increase. THIS MAY RESUL T IN OVER-FIRING DUE TO LOSS OF PRESSURE CONTROL, SHOULD THERE BE A SUBSEQUENT INCREASE IN INLET PRESSURE.

CAUTION: RECENT CODE CHANGES REQUIRE the use of 5 PSI LABELED REGULATORS IN 5 PSI SYSTEMS. REGULATORS LABELED 2 PSI ARE NOT

APPROVED FOR 5 PSI USE.

NOTE: At supply pressures in excess of 2 PSI, the new ANSI Z21.80 Line Regulator Standard requires a means

(an Over-Pressure protection Device / OPD) - approved and tested with 5-PSI or 2-5 PSI Labeled regulator - to limit the downstream pressure to 2-PSI maximum, in the event of regulator failure.

CONSULT THE FACTORY OR THE REGULATOR MANUFACTURER FOR THE CAP ACITIES & PRESSURE DROP FOR A COMBINATION OF 5-PSI REGULATOR & OPD.

SECTION 4.9 — UNDERGROUND INSTALLATIONS

1. CODE REQUIREMENTS When gas piping runs are located below grade in contact with earth or other material that could corrode the piping, codes require that the gas piping shall be protected against corrosion. When piping is installed underground beneath buildings, codes require that the piping shall be encased in a conduit sealed inside of the building and vented above grade to the outside. The conduit shall be designed to withstand the superimposed loads. NO FITTINGS OR COUPLINGS ARE PERMITTED BENEATH BUILDINGS.

SECTION 4.9B — TracPipe PS FITTING ATTACHMENT INSTRUCTIONS

1. TracPipe PS uses standard AutoFlare

fittings. To assemble fittings follow instructions found in the TracPipe Design Guide and Installation Instructions Section 4.2.

2. To install TracPipe PS for underground

service, cut the black polyethylene sleeve in the same manner you would cut the 1-1/4" thru 2" size TracPipe product , with a stan- dard tubing cutter Ridgid™ 152 or equal,

and a cutting wheel Ridgid™ catalog no. 33195 (Poly Wheel) (P/N E:5272). Note: For the 1-1/4" thru 2" size black polyethylene sleeving, the larger tubing cutter Ridgid™ no. 152 must be used due to the diameter of the sleeving. CAUTION: Do NOT

use a hacksaw or other sawing device to cut the black polyethylene sleeving as it may damage the inner TracPipe gas piping.

3. Cut the TracPipe gas piping using the same tubing cutter per standard instructions in the Design and Installation Guide.

4. Slip the required heat shrink polyolefin cuff over the TracPipe gas piping to each end of the black polyethylene sleeving and heat shrink the polyolefin cuff to the gas piping and the black polyethylene using a heat gun or other suitable heat source.

NOTE: Omegaflex

, Inc. recommends the use of a heat gun. Extreme care should be taken when applying heat to the polyolefin cuff as not to damage the TracPipe gas piping yellow jacket.

5. Where local codes require venting, slide plastic tee (P/N: FGP-VT-SIZE) over end of TracPipe and insert into end of the black polyethylene sleeve on the end of the run which is nearest to the outside wall of the building. Heat shrink the polyolefin tubing to the vent tee and to the TracPipe gas pipe.

SECTION 4.9C — UNDERGROUND PS WITH FLEXIBLE POLY TUBING

Product Description: Flexible, corrugated polyethylene tubing in sizes to fit T racPipe PS (patented) underground gas piping. Poly tubing is easy to bend, providing flexibility at the ends of a length of TracPipe PS to facilitate transition to above ground. Use with available heat shrink cuffs and couplings to provide a completely sleeved underground gas piping system that can be easily vented when required by codes.

Installation Instructions

1. Determine the location where the smooth black sleeve will make the transition to flexible poly tubing. This is typically the transition point from below ground to above ground but can also occur above or

below ground wherever a tight bend of up to 90 degrees is required.

3. Insert a barbed coupling by sliding it over the exposed length of TracPipe and pushing firmly into the smooth black sleeve until all barbs are covered up to the coupling’s center.

2. Cut through the smooth black sleeve using a Ridgid™

151 or similar tube cutter of the

appropriate size for the tubing.

6.Position a section of heat shrink cuff material to cover the coupled smooth sleeve and corrugated sleeve. This cuff should be centered over the plastic barbed coupling and cover roughly two (2) inches of each black sleeve. NOTE: This cuff is internally treated with a thermal adhesive and cannot be removed without damage after the heat shrink operation.

7. Carefully shrink the cuff using a heat gun. As cuff is heated it will conform to the diameters of the sleeves and the thermal adhesive will set to lock the combined materials.

8. Above Ground, follow the preceding steps to install a plastic barbed tee for vented systems, or shrink a cuff directly onto the exposed TracPipe for non-vented instal- lations. (Most codes require underground sleeving to be vented for under building slab installations such as island ranges).

3. Using the appropriate tubing cutter with TracPipe #FGP-E-5272 cutting wheel, score the black sleeve approximately half of the way through. Use extreme care not to cut or score the stainless corrugated pipe! Typically, no more than two turns in on the cutter is sufficient.

4. Finish cutting through the sleeve down to the stainless corrugated pipe using a sharp utility knife.

7. Remove adapter and split rings from fitting. Attach adapter to equipment. Slip coupling and nut over end of pipe all the way to expose first corrugations of pipe. Insert split rings into first corrugation as shown.

8. Holding the black coupling, slide fitting up to capture split rings into nut. Be sure split rings slip all the way to the base of the internal threads. Assembly is now ready to be attached to the adapter on the equipment.

5. Using a twisting motion, remove the black sleeve and yellow jacket from the pipe. It may be necessary to cut sleeve longitudinally and peel off for larger sizes.

Inspect stainless pipe for scoring fr the tubing cutter.

6. Using the tubing cutter, trim corrugated pipe to strip length specified on chart. Cut slowly in the root of the corrugation in the same manner you would cut copper tubing. Inspect end of pipe for a clean cut without tears in corrugation.

9. Thread nut onto adapter previously installed on the equipment. Using appropriate wrenches, hold adapter and tighten nut to proper torque specified. Do not over tighten or use any pipe dope or thread sealants on this connection. This is a metal-to-metal seat and will not seal if pipe dope or thread sealants are used. Sealants are to be used on the NPT connection to the equipment only!

NOTE: When installing coupling FGP-UGCSIZE the same instructions apply, except metallic parts of the fitting must be wrapped in a code approved manner (e.g. mastic used for wrapping metallic pipe).

SECTION 4.10 — ELECTRICAL BONDING/GROUNDING

1. The piping system is not to be used as a grounding conductor or electrode for an electrical system. In accordance with The National Fuel Gas Code NFPA 54/ANSI Z223, “each above ground portion of a gas piping system upstream from the equipment shutoff valve shall be electrically continuous and bonded to any grounding electrode, as defined by the National Electrical Code, ANSI/NFPA 70 1999 Edition.”

2. For bonding of the TracPipe system, a bonding clamp must be attached to the brass AutoFlare fitting adapter (adjacent to the pipe thread area — see Figure 4-21) or to a black pipe component connected to an AutoFlare fitting. The corrugated stainless steel portion of the gas piping system SHALL NOT be used as the bonding attachment point under any circumstances. Bonding electrode conductor sizing shall be in accordance with Article 250 (Table 250-66) of ANSI/NFPA 70 1999 Edition. The bonding is a requirement of the National Electrical Code.

b. Bonding: The process of making an

electrical connection between the grounding electrode and any equipment, appliance, or metal conductor: pipes, plumbing, flues, etc. Equipment bonding serves to protect people and equipment in the event of an electrical fault.

c. Equipotential Bonding: The process

of making an electrical connection between the grounding electrode and any metal conductor: pipes, plumbing, flues, etc., which may be exposed to a lightning strike and can be a conductive path for lightning energy towards or away from the grounding electrode.

4. Lightning strike density varies considerably around the United States. The highest density is experienced in the Gulf Coast and Florida. The lowest lightning strike density is the Pacific Coast states. See map of the United States (Figure

4.22) for the average number of thunderstorm days per year for a specific region or state.

Section 4.10A — CounterStrike

Installation Instructions

1. Equipotential Bonding of the gas piping system is recommended using shortest distance possible.

2. An equipotential bonding/grounding connection shall be made between the fuel gas piping system and the electrical service grounding electrode. The bonding jumper should be sized in accordance with NEC Table 250.66 (based on the main service conductor size), or in accordance with NFPA 780 Paragraphs 4.14.1.2 thru

4.14.1.4 (main-size lightning conductors) Tables 4.1.1.1(A) and (B): Class I and Class II wire size. Bonding and grounding connections are to be made by a qualified technician.

If the building to be piped is in a high lightning flash density area or a region with a high number of thunderstorm days per year, consideration should be given to uti-

lizing the Lightning Risk Assessment method given in Annex L of NFPA 780 for a determination of the need for a lightning protection system.

Notes:

a. If possible, avoid running the bonding

jumper a long distance through the building. The connection should be as

t as possible. Gas meter should be

shor near the electrical service if possible. If not, the bond can be connected at any point in the system per (Figure 4-21).

b. Lightning induced voltages seeking

ground are subject to impedance; utilize a braided or stranded bonding jumper for greater surface area, rather than solid wire.

c. Upon completion of the TracPipe

CounterStrike Gas Piping System installation and prior to gas service initiation, check to see if the bonding has been completed.

3. Routing of gas piping should be as low in the structure as reasonably possible for best performance.

4. TracPipe CSST runs, including CounterStrike, should be installed with a bend radius of 8 inches or more whenever possible; this will reduce the possibility that energy will jump from the piping to other conductive surfaces.

5. For CounterStrike with BLACK outer jacket installations, the installer shall meet local building codes with respect to flame spread and smoke density regulations for non-metallic materials. If run through return air plenums, black jacket shall be removed.

6. For through penetration fire stop systems per UL classification requirements, remove the BLACK outer jacket when

passing through a fire stop.

7. The instructions for cutting the tubing and for making fitting connections to CounterStrike are identical to those for the standard yellow-jacketed TracPipe.

8. The use of TracPipe PS-II should be considered for use as the trunk line under the building slab from the meter set to the manifold station. This practice routes the elevated pressure portion of a 2 PSI system completely away from any potential contact with other building metallic systems which can become energized in the event of a nearby lightning strike.

9. Optional: Install GasBreaker excess flow devices at the meter and appliance locations. See TracPipe design and Installation Guide Section 3.3. (Mandatory where required by code.)

SECTION 5.2 — REPAIR OF DAMAGED PIPING

If the tubing is damaged, refer to the following sections to determine the severity of damage and, if necessary, the method of repair.

1. No repairs or replacement of the tubing is necessary if the tubing is only slightly dented due to impact or crushing as indicated in Figure 5-1.

2. The tubing must be replaced under the following circumstances:

a. The tubing has been significantly

crushed or dented (Figure 5-2)

b. The tubing has been damaged by

puncture of any kind, i.e., nails, screws, drill bits, etc.

c. The tubing has been bent beyond its

minimum bend radius so that a crease or kink remains. (Figure 5-3)

Figure 5-1 – Repair Unnecessary.

No Significant Damage to the Tubing

Due to Impact or Crushing

METHOD OF REPAIR

A line splice can be made using an autoflare coupling, but if the tubing run is short and easily accessible, the preferred repair method is to replace the entire length. Tubing run can often be replaced faster than repairing the damaged section with a splice and this does not add any additional fitting joints to the system. The Auto Flare fittings can be re-attached to the new tubing run

1. Where repairs or replacements involve Corrugated Stainless Steel Tubing systems of different manufacturers, the systems can be joined again through standard pipe couplings and the appropriate CSST fittings.

CHAPTER 6

PRESSURE/LEAKAGE TESTING

SECTION 6.0 — PRESSURE TEST PROCEDURE

The final installation must be inspected and tested for leaks at 1 1/2 times the maximum working pressure, but not less than 3 PSI, using the procedures specified in Part 4 “Inspection, Testing and Purging” of the National Fuel Gas Code*, NFPA 54/ANSI Z223. 1-1996* or subsequent editions of this code in effect at the time of the test. Pressure test according to these guidelines or to local codes. When local codes are more stringent, local codes must be followed. If no local codes apply , test according to the National Fuel Gas Code. The installer should never pressure test above 10 PSI with the pounds-to-inches regulator installed. This may damage the regulator.

1. Pressure testing should be performed during rough construction of the facility before interior walls are finished. This will permit a more complete inspection of the piping system during the pressure testing, and save costly rework in the event of leaks or other problems. TracPipe is not responsi- ble for repairs necessary to correct defects discovered after interior walls are finished.

2. Do not connect appliances or pressurize the system with fuel gas until after the pressure test is completed.

3. All gas outlets for appliance connections should be capped during pressure testing.

4. USE ONLY NON-CORROSIVE LEAK CHECK SOLUTIONS. Rinse with water and dry the tubing thoroughly after leak detection.

5. Most utilities perform a leak test after setting the gas meter and prior to turning on the gas. This test is performed after the final construction is complete and finished interior walls are in place. This test is performed to assure no damage was done to the tubing during the closing-in construction process.

6. NOTE: When pressure testing TracPipe

PS-II, it is necessary to remove at least one fitting vent plug to insure proper test results on the stainless steel tubing.

SECTION 6.1 — Pressure Test for

Elevated Pressure Systems

NOTE: DO NOT SUBJECT TracPipe SIZES 1-1/2" OR 2 INCH TO EXCESSIVE PRESSURE. Pressure Test 1-1/2" and 2" sizes to local code requirements but not to exceed 40 psi. In the absence of code rquirements, test to 1-1/2 times actual working pressure, not to exceed 40 psi

The 2-5 PSI system requires a two-part pressure test. (See Figure 6-1) The first part is performed on the elevated pressure section, between the meter connection and the pounds-to inches house line regulator.

The second part is performed on the low pressure section, between the pounds-to-inches house line regulator and the gas appliance outlet. If a steel pipe “jumper” is inserted in place of the house line regulator the entire system can be pressure tested in one step.

SECTION 6.1A — APPLIANCE CONNECTION LEAKAGE CHECK PROCEDURE

1. After the final pressure test, inspection and final construction is complete (finished interior walls) connect the appliances to the tubing system.

2. This final connection can be accomplished by a stainless steel flexible connector, direct connection with CSST tubing or with rigid black pipe. See section 4.6 for installation details and guidelines.

3. T urn the gas on at the meter and inspect for leakage before operating the appliances.

This will insure adequate pressure to each appliance under full-load conditions.To accomplish this, measure the line pressure at the appliance connection while operating the appliance.

2. The inlet pressure for typical natural gas appliances should measure between 4 and 6 inches water column under full-load conditions. If this pressure can not be obtained a slight adjustment to the pounds-to-inches regulator may be necessary to increase the line pressure. Do not set any system regulator over the system design pressure (2 PSI).

B. Spring Adjustment

4. Connections made at the appliances should be leak checked with a bubble solution. Before placing the appliances in operation the tubing system should be purged. This displaces the air in the system with fuel gas. Be sure to bleed tubing system into a well ventilated area.

NOTE: Leak test solutions may cause corrosion to some types of material in the gas tubing system. Be sure to water rinse after the test and thoroughly dry all contacted material. Also, the vent limiter should not be leak tested with a liquid test solution. This will contaminate the internal ball check mechanism or plug the breathing hole, resulting in erratic regulator operation.

SECTION 6.1B — REGULATOR PERFORMANCE

A. Load Response

1. A performance test should be conducted while operating all appliances at full load.

1. The 2 PSI system pounds-to-inches house line regulator can be adjusted with an outlet pressure ranging between 7 and 11 inches of water column. The regulator must be adjusted according to the manufacturer’s recommended procedure. A pressure gauge mounted just downstream of the regulator can monitor the set pressure under various loads.

2. The regulator is typically set when the system is operating at approximately 75 percent of maximum load.

3. The average natural gas appliance is designed to operate at 3 to 4 inches water column manifold pressure, and a pressure difference of 1 to 2 inches of water column across the appliance regulator which will prevent slow regulator response. Thus, the appliance regulator will operate best at 5 to 6 inches water column inlet pressure. In this case, the 2 PSI house line regulator should be reset to deliver approximately 8 to 10 inches of water column outlet pressure under load to allow for 3 inches of water column pressure drop in the tubing. Some appliances may have different inlet pressure requirements.

CHAPTER 8

DEFINITION OF TERMINOLOGY

A.G.A. – American Gas Association ANSI Z223.1 1988 – 1988 edition of the National Fuel

Gas Code published by American National Standard Institute. Also known as NFPA 54 (National Fire Protection Association).

Appliance (Equipment) – Any device which utilizes natural gas or propane as a fuel or raw material to produce light, heat, power, refrigeration or air conditioning.

Approved – Acceptable to the authorities having jurisdiction.

Authority Having Jurisdiction – The organization, office or individual responsible for “approving” equipment, an installation or a procedure.

Btu – Abbreviation for British Thermal Unit, which is the quantity of heat required to raise the temperature of one pound of water one degree Fahrenheit .

more than a certain upper limit pressure above the set point.

Header (manifold) – A pipe or fitting to which a number of branch lines are connected.

ID – Inside diameter of pipe or tubing. Inches (") W.C. – Method of stating pressure mea-

sured in inches of water column by a manometer or pressure gauge. Commonly used in the gas industry when the pressure is less than one (1) PSI.

1 PSI = 28 in. W.C. approximately 1/2 PSI = 14 in. W.C.

1/4 PSI = 7 in. W.C. Load – The amount of gas in Cfh required by an

appliance, or group of appliances, per their rating plate.

Cfh – Gas flow rate stated in cubic feet per hour. Clothes Dryer – A device used to dry wet laundry

by means of heat derived from the combustion of natural gases.

Design Pressure – The maximum operating pressure permitted by this document, as determined by the design procedures applicable to the materials involved.

Drip Leg – The container (dirt trap pocket) placed at a low point in a system of piping to collect foreign material or condensate and from which it may be removed.

EHD (Effective Hydraulic Diameter) – A relative measure of Flow Capacity; This number is used to compare individual sizes between different manufacturers. The higher the EHD number the greater flow capacity of the piping.

Full Lockup – The capability of totally stopping the flow of gas if the load goes to zero, thus preventing the downstream pressure from increasing

L. P. Gas – Fuel gas that is stored and transported in a liquid state, i.e., propane, butane, and mixtures of these and other heavier hydrocarbons.

Meter – An instrument installed to measure the volume of gas delivered through a piping system.

Manometer – A “U” shaped tube filled with water, or mercury where the pressure applied to one leg of the “U” will push the liquid column a measurable distance. Also known as a “U” gauge.

OD – Outside Diameter of pipe or tubing. 1/2 PSI – A shortened way of stating 1/2 pounds

per square inch gauge. Also the name of a low pressure piping system supplying gas from the meter at 1/2 PSI to each appliance pressure regulator.

Piping – As used in this document, either pipe or tubing, or both.

a. pipe – Rigid conduit of iron, steel, copper,

brass or aluminum.

b. tubing – Semi rigid conduit of corrugated

stainless steel.

Pressure – Unless otherwise stated, is

expressed in pounds per square inch above atmospheric pressure, i.e. gage pressure (PSI).

Pressure Drop

– The loss in static pressure of

gas due to friction or obstruction in tubing, valves, fittings, regulators and burners.

Pressure Regulator

– A valve which reduces

and controls pressure. It automatically opens and closes in response to changing pressure conditions in the downstream piping.

Regulator, Service (PSI

– PSI or inches w.c.) – A

device installed by the serving gas supplier to reduce and limit the service line gas pressure. This valve reduces the service pressure to the metering pressure. It is located upstream of the gas meter.

Regulator Vent

– The opening in the atmos-

pheric side of the regulator housing permitting the in and out movement of air to compensate for the movement of the regulator diaphragm.

– Pounds per square inch gauge. The

PSI

pressure, as read from a measurement gage or device. Gauge pressure is pressure above atmospheric pressure.

Purge

– To displace the original air, or gas, or

a mixture of gas and air in a gas conduit with a new air/gas mixture.

Regulator, Appliance (inches w.c.

– inches w.c.) – A

device for controlling and maintaining a uniform pressure to the manifold of gas burning equipment. This valve is typically part of the appliance. It reduces the pressure from 5.5" w.c. to the manifold pressure in the appliance. (approximately 3.5" w.c.).

Regulator, House Line (PSI

– inches w.c.) – A device

placed in a gas line between the service regulator and the appliance regulator for controlling, maintaining or reducing the pressure in that portion of the piping system downstream of the device. This valve reduces the house line pressure (Typically 2 PSI) to the regulator manifold pressure (Typically 8-10" w.c.).

Specific Gravity

– As applied to gas, the ratio of

the weight of a given volume to that of the same volume of air, both measured under the same conditions.

– A shortened way of stating 2 pounds

2 PSI

per square inch gauge pressure. Also the name of a piping system supplying gas at 2 PSI to a house line regulator which then reduces the pressure to inches W.C. upstream of the appliance regulator.

Valve, Manual Shut-off

– A valve (located in the

piping system and readily accessible and operable by the consumer) used to shut off individual equipment.

Vent Limiter Device

– Restriction/orifice type

device in the vent outlet of a pressure regulator that controls or limits leakage, in the event of a diaphragm leak. It also allows the diaphragm to move freely to control pressur e.

APPENDIX B

MANUFACTURED HOUSING GUIDELINES

A. CODE AND ADMINISTRATIVE REQUIREMENTS

1. Manufactured homes and mobile homes bearing an insignia or required to bear an insignia must comply with Title VI 24 Code of Federal Regulations, The National Manufactured Housing Act of 1974 Part 3280. In most jurisdictions this requirement remains in force when the structural, electrical plumbing or mechanical systems are

altered. The Code of Federal Regulations, Housing and Urban Development, Part 3280 Manufactured Home Construction and Safety Standards is applicable throughout the

USA for manufactured housing construction (also known as “HUD code” housing).

2. There are other types of factory-built housing that do not fall directly under the classification “HUD code” which must also be reviewed for special installation considerations when designing a CSST gas piping system or appliance retrofit. Some examples of this type of housing are Assembly Buildings, Panelized, Modular, and Production Build. TracPipe should not be considered for RVs, which are subject to over the road use and not just initial placement or repositioning.

3. Part 3280 Manufactured Home Construction and Safety Standards 1994 has not been revised or updated for several years. There has been an effort by both NFPA and CABO (now a part of the ICC) to have the US Congress adopt a new Manufactured Housing Code. The latest version of the CABO Code ICC/ANSI 2.0 Manufactured Housing Construction Safety Standards is available but has not been adopted by Congress.

4. Omegaflex has obtained a written opinion from the U.S. Department of Housing and Urban Development regarding the use of TracPipe CSST. This HUD decision states “CSST, such as TracPipe, is allowed to be used in HUD manufactured homes (based upon incorporation of NFPA 54-1992 ANSI 223.1 The National Fuel Gas Code into Section 3280.703 Minimum Standards).” This opinion shall be confirmed with State authorities responsible for inspections of HUD Code buildings prior to installing TracPipe after the home has left the factory. For factory installations, approval by the DAPIA (Manufacturer’s Design Approval Primary Inspection Agency) is normally required for the piping system design. Contact Omegaflex for specification data and a copy of the HUD decision letter.

B. PIPING SYSTEM DESIGN REQUIREMENTS

1. The primary information for any TracPipe installation is contained in the TracPipe Design Guide and Installation Instructions (latest edition). This guide provides manufacturer’s instructions that are a requirement of the ANSI/CSA LC-1 Standard governing certification and test requirements for Corrugated Stainless Steel Tubing. Manufactur

er’s instructions must be followed.

2. Sizing for gas piping systems in HUD Code homes must be performed in accordance with Part 3280 (Natural Gas piping system acceptable for LP-gas). System sizing is to be done with Low Pressure Capacity Charts utilizing 0.5-inch water column drop. (see Chart N-1 in the TracPipe Design Guide)

3. The natural gas supply connections shall not be less than the size of the gas piping but shall not be smaller than 3/4-inch nominal pipe size. Gas supply connection shall

be beneath an exit door. Gas supply connection shall be rigidly anchored to a

not structural member within 6 inches of supply connection. All exterior openings around piping shall be sealed to resist the entrance of rodents.

4. Where fuel gas piping is to be installed in more than one section of an expandable or multiple-unit home, crossover connections between sections of the home shall be constructed by one of the following methods:

A. Listed quick disconnect device, designed to provide a positive seal of the supply

side of the gas piping system when such device is separated.

B. Flexible connectors listed for exterior use and a shutoff valve of the non-dis-

placeable rotor type conforming to ANSI Z21.15, installed on supply side.

C. Direct plumbing (CSST) sized in accordance with Natural Gas Low Pressure

Capacity Chart N-1 (see above).

5. The flexible connector, direct plumbing pipe or “quick-disconnect” device shall be provided with protection from mechanical and impact damage and located to minimize the possibility of tampering. For gas line crossover connections made with CSST or flexible connectors, the crossover points shall be capped on the supply side to provide a positive seal and covered on the other side with a suitable protective covering.

6. All points of crossover shall be accessible from the exterior of the home.

C. INSTALLATION REQUIREMENTS

1. The preferred location for CSST flexible gas piping is beneath the floor and inside or above the I-beam flange. This location will provide the best protection from transit damage. Appliance stub-outs are easily made utilizing termination mounts or flange mounts rigidly attached to the floor. Final connections can be made with approved flexible appliance connectors downstream from the appliance shut-off valve. All floor penetrations shall be sealed to resist the entrance of rodents. All CSST should be within the envelope or rigidly attached to the I-beam flange.

2. Where CSST must cross an I-beam flange, the piping shall be secur house flange to protect the CSST. Angle iron, C-channel or a wooden block are recommended means of attachment. It is preferred to drill through a wooden structural member if possible to avoid crossing the flange.

3. In open joist construction, routing should be within the open web portion of the fabricated joist wherever possible. This location provides necessary support points at each joist location.

4. In all locations, CSST must be supported in accordance with the manufacturer’s instructions (every 4 feet-3/8 size, 6 feet-1/2 size, 8 feet-3/4 size and 1 inch size) Support should be with metal EMT conduit straps or two-point attachment plastic clips suitable for the size of the tubing.

ely attached to the

5. If a manifold is used, it shall be rigidly mounted to the I-beam flange. This applies to parallel system layouts. Gas pressure in HUD Code homes is limited to 14 inches water column maximum. Line pressure regulators are not necessary for this pressure and should not be used.

6. The gas piping shall be bonded to the frame of the home by the use of: a. Solderless type grounding terminal with a star washer bolted to the chassis;

b. Grounding clamp attached to a gas piping fitting. (For attachment of clamp to

TracPipe fitting, refer to Section 4.10 – Electrical Bonding/Grounding. Do not clamp to the stainless steel portion under any circumstances.); and

c. A bonding conductor of #8 copper wire.

7. Concealed tubing: CSST shall not be run inside walls, partitions or roofs. Where tubing passes through walls, floors, partitions, roofs, or similar installations, such tubing shall be protected by the use of weather resistant grommets that shall snugly fit both the tubing and the hole through which the tubing passes. DO NOT remove the yellow polyethylene jacket in any penetrations.

8. All CSST tubing joints shall have any exposed sections of stainless steel piping wrapped with silicone self-bonding tape. The under-floor portion of the manufactured home is considered an outdoor location. Pr under the floor.

9. Retrofit of appliances:

oper support (per item 4 above) is required

a. The gas supply connection shall be rigidly anchor

6 inches of supply connection.

b. CSST shall be supported and protected per manufacturer’s instructions. (See items

4 and 7 above.)

c. Pressure test gas piping per Item D 1 below before operating appliance.

D. INSPECTION AND TEST REQUIREMENTS

1. Pressure test in accordance with Part 3280.705k (8) testing for leakage (8 i) before appliances are connected and (8 ii) after appliances are connected.
