SECTION 1: INTRODUCTION / JANUARY 2019

1.1 GENERAL USER WARNINGS (CONTINUED)

A FlashShield™ Flexible Gas Piping system offers advantages over other gas delivery systems because of its corrugated
design. In contrast to rigid steel pipe, FlashShield™ does not require intermediate joints in most installations because the
tubing is capable of being installed in one continuous run, reducing not only the total number of joints, but also the
potential for leaks at joints. FlashShield’s flexibility also affords more installation options because an installer can avoid
existing obstacles, and it eliminates the repetitive measuring, cutting, threading and joint assembly that is common with
installation of rigid steel piping systems. FlashShield™ flexibility offers even further safety advantages in geographic areas
that are prone to seismic activity because the tubing is able to move as the ground or the structure shifts.

While FlashShield™ provides significant advantages over more rigid gas delivery systems, its flexible design may make it
more likely than steel pipe to be punctured by a nail or other sharp objects, or damaged by other extraordinary forces such
as lightning strike, depending on the circumstances.

Corrosive substances: Steel piping, brass fittings and valves can be corroded by various chemical substances which may be
present on a jobsite or in a structure. Chlorinated compounds can cause pitting and crevice corrosion of stainless steel.
Ammonia and other nitrogenous compounds can cause stress corrosion cracking of brass. FlashShield's jacket system
provides protection from many harmful substances and should remain intact over the lengths of stainless steel tubing to
maintain this protection.

While not exhaustive, the list below provides guidance of substances which should not come into contact with stainless
steel or brass. If there is a question about the suitability of a certain substance in the environment, the user should refer to
the ingredient list or contact the manufacturer.

Chlorinated compounds (chloride, chlorite, chloric, chlorous, chloro, chlorate):

• Some household soaps*

• Masonry cleaner (Muriatic acid)

• Soldering flux

• Bleach

• Pool chemicals

• Ice melt

• Soils, soil water, concrete

Amonia and ammonium containing compounds:

• Household cleaners

• Fertilizers

Nitrogenous compounds, such as amines:

• Herbicides, pesticides, fungicides, insecticides

* Some household soaps that contactors have used to make leak check solution may contain chlorides which can cause

corrosion to metallic components. Only use leak test solution which are labeled as non-corrosive, for gas piping systems.

Caution: Tube ends are sharp, use care when handling.

d) e corrugated stainless steel tubing system has a number of essential hardware and design differences from conventional

gas piping using rigid steel pipe and copper tubing. ese differences are described as follows:

• In many applications, the tubing is sized for individual gas appliance loads and is, therefore, usually small in diameter.
e tubing may also be installed in a parallel fashion from a central distribution manifold rather than a series layout
commonly used for rigid pipe systems.

• Corrugated Stainless Steel Tubing is pulled through the structure similar in fashion to electrical wiring and therefore
requires different handling and installation techniques than rigid pipe.

• Rigid termination of the tube ends is required.

• Flexibility and strike plates protect the CSST allowing it to be run in concealed spaces.

SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019

SECTION 3.0 SYSTEM CONFIGURATION

3.1 CONFIGURATION

3.1.1 INTRODUCTION

is section is intended to help in the design and sizing of FlashShield™ CSST fuel gas piping systems. e form -printed
on the previous page is to aid in keeping track of the system requirements as well as organizing the system configuration
and sizing numbers. Refer to the Gastite website (www.gastite.com) for additional sizing tools.

e FlashShield™ gas piping system is required to be tested, listed, and installed in accordance with the Standard For Fuel
Gas Piping Systems Using Corrugated Stainless Steel Tubing, ANSI LC1. is standard, among other things, requires the
manufacturer to provide installation instructions including the necessary pipe sizing tables and methods of sizing.

3.1.2 SYSTEM REQUIREMENTS

• Determine the local piping restrictions prior to installing the flexible gas piping. Confirm that the local administrative
authority has accepted the use of flexible gas piping. Corrugated Stainless Steel Tubing has been accepted by all major
code bodies, but local or state adoption of these codes often lags behind. Check with the local administrative authority or
an authorized FlashShield™ distributor for approval in your area.

• Determine metered (supply) pressure. A gauge can be used to measure the supply pressure or the utility will provide a
supply pressure rating.

• Determine appliance demand. Every appliance will have a manufacture’s nameplate containing BTUH or CFH
requirements as well as minimum and maximum operating pressures.

• Refer to building plans or prepare a sketch showing the location of each appliance. When preparing this sketch keep in
mind the safest, easiest, and shortest distance locations to run the piping. Label the pipe segments and the corresponding
lengths. Take note of fittings needed e.g. tees, manifolds, reducers.

3.1.3 REFERENCE DATA FOR PROPER SYSTEM SIZING

• Determine the total capacity needed for all appliances. CFH or BTUH equivalents for natural gas or propane can be
obtained from the local gas utility or propane supplier. e capacity tables within this guide or other approved CSST
tables should be used to determine pipe sizing for FlashShield™ needed to meet BTUH input load requirements.

TABLE 3-1 REFERENCE DATA FOR PROPER SYSTEM SIZING

PRESSURE CONVERSION FACTORS FUEL GAS INFORMATION

1/4 PSI = 6.921"WC = (approx. 7"WC) Natural Gas Propane

1/2 PSI = 13.842"WC = (approx. 14"WC) BTU per Cubic Foot = 1000 2516

1 PSI = 27.684"WC = (approx. 28"WC) Specific Gravity = 0.6 1.52

2 PSI = 55.368"WC = (approx. 56"WC)

5 PSI = 138.42"WC = (approx. 140"WC)

Note: “Pressure Drop Curves are expressed in terms of Cubic Feet per Hour
(CFH). To determine the CFH for Natural Gas, divide the BTU load by 1000.
To determine the CFH for Propane, divide the BTU load by 2516.

Refer to Section 7.0 for gases with a specific gravity other than 0.60.

SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019

3.1.4 DETERMINING SYSTEM LAYOUT

A) SERIES SYSTEMS

A series layout (Fig 3-1) is the most common
arrangement utilized for rigid pipe systems for low
pressure. ese usually consist of a main run (header)
with tees branching off to each appliance. In a
traditional series system, the service pressure down
stream of the meter is typically less than 1/2 PSI.

B) PARALLEL SYSTEMS

In a parallel system (Fig. 3-2) a main run from the
meter supplies a central distribution manifold. e
appliances are serviced by individual runs from the
manifold. e manifold station is best located close
to the greatest load, typically the boiler or furnace.

C) DUAL PRESSURE SYSTEM

A dual pressure system (Fig. 3-3, 3-4) incorporates
two operating pressures downstream from the meter.
e first pressure, set by the service regulator at the
meter, is usually 2 PSI but can be higher or lower
depending on code restrictions and gas company
policy. is part of the system is sized separately and
ends at the pounds-to-inches regulator inlet. Tables
4-7, 4-8 and 4-9 show maximum loads vs. inlet
pressures to the regulator.

Fi g. 3 -1

Fig . 3-2

Fig. 3-3

e second pressure, at the outlet of the pounds-to­inches regulator, is under 1/2 PSI; usually 8"WC
for natural gas and 11"WC for propane regulators
supplied by Gastite®. Generally, a parallel system
requires a higher total footage of smaller diameter
tubing and fewer fittings compared to a series layout.

SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019

D) MULTIPLE MANIFOLD SYSTEMS

For those installations in which the energy load demand
is large or the appliances are installed throughout the
structure with long distances from the meter, a multiple
manifold system may be used (Fig. 3-5, 3-6). Elevated
pressure systems are a safe, efficient method of providing
for larger BTUH load demands while maintaining
smaller pipe diameters.

E) COMBINATION STEEL / CSST SYSTEM (HYBRID)

In a hybrid system (Fig. 3-7), corrugated stainless steel
tubing is used in combination with rigid pipe or copper
tubing. In lower pressure systems it is often advantageous
to use both CSST and rigid pipe to help minimize
pressure drops typically encountered on systems with
high loads and/or long runs. FlashShield™ flexible Gas
Piping is approved for use in combination with all
approved fuel gas-piping materials by using approved
pipe threads at the interface.

F) ELEVATED PRESSURE SYSTEM

In a complete elevated pressure system (Fig. 3-8),
corrugated stainless steel tubing is used to deliver
pressures in excess of 1/2 PSI to a pounds-to-inches
regulator positioned directly in front of each appliance.
is is an alternate method of installation used to
minimize pipe size on systems with high loads and/or
long runs. Regulators shall be sized per the largest single
appliance, see Table 4-10.

SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019

3.1.5 ALLOWABLE PRESSURE DROP

With respect to gas pipe sizing, the intent of all model codes is to ensure that there is sufficient gas volume and pressure
supplied to the appliance for proper operation. Language from the International Fuel Gas Code clearly illustrates this point.

“Allowable Pressure Drop: e design pressure loss on any piping system under maximum probable flow
conditions, from point of delivery to the inlet connection of the equipment, shall be such that the supply
pressure at the equipment is greater than the minimum pressure required for proper equipment operation.”

e FlashShield™ low-pressure tables are intended for use at a system pressure of 1/2 PSI or less, which encompasses the range
of commonly delivered utility pressures and equipment requirements. To determine which table to use determine the system’s
allowable pressure drop. e appropriate pressure drop can be calculated by subtracting the appliance inlet pressure (typically
5"WC for NG, 10.5"WC for LPG) from the gas source pressure (gas meter for NG, secondary regulator for LPG). Use the
FlashShield™ capacity table labeled with the appropriate allowable pressure drop and gas type. Increasing the available pressure
drop will increase the available BTUHs, thus decreasing pipe sizes. It is advantageous to allow for a larger pressure drop.

e Summation Method of pipe sizing calculates the actual pressure loss through each section of pipe. e sum of all the
losses is subtracted from the starting supply pressure to determine the inlet pressure to each appliance. e appliance inlet
pressure must fall within the manufacturer’s range for proper operation.

Note: Regardless of sizing method employed, the typical NG system should be sized for a minimum appliance inlet
pressure of 5"WC and 10.5"WC for LPG system. Pressures less than the typical minimums may be sufficient for proper
appliance operation but should be reviewed with the manufacturers’ input rating and the local administering authority.
Conversely, some modern higher performance appliances require an inlet pressure greater than the typical minimums.
Check the manufacturers’ input rating before sizing.

3.1.6 SIZING METHODS

Capacity Tables from this Guide (Section 7) or appropriate code approved tables must be used when sizing FlashShield™
CSST. e sizing tables used in this manual include losses for four 90-degree bends, and two end fittings. Tubing runs with
larger numbers of bends and/or fittings should be increased by an equivalent length of tubing to the following equation: L
= 1.3 (N): where “L” is additional length of tubing, and “N” is the number of additional fittings, or 90 degree bends.

FlashShield™’s Longest Run tables and Summation tables are produced from the same fluid flow equations. As such, they
will provide the same results taking into account any rounding of distance or capacity. ese fluid equations come from
data produced by a third party laboratory. e testing was performed on actual FlashShield™ CSST while tables in the code
reflect the most restrictive CSST.

THE LONGEST RUN METHOD:

A modified version of the longest run (commonly used in conventional rigid pipe systems) is presented here and used in
Examples 1, 2 & 3. is method may be used for any pressure as listed in the appropriate Capacity Table.

For sizing each length of pipe, determine the total gas load for all appliances serviced by that section and the maximum
distance over which that particular section delivers gas. e maximum distance includes overall length from the meter to
the furthest appliance serviced by that run. Refer to Section 7 Capacity Tables for the maximum flow capacity of CSST at
the required piping length.

For sizing dual-pressure systems, the piping from the meter to the pounds-to-inches regulator is sized separately from the
piping downstream of the regulator outlet. is procedure is shown in Examples 4 & 5.

SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019

Sizing for a Hybrid System (one that includes both rigid pipe and CSST) is accomplished by using the longest run method
to determine the appropriate pipe size for a given load and run length. Each segment of the piping system uses the appro­priate sizing table for that particular piping material. is procedure is shown in Examples 6 & 7.

SUMMATION METHOD:

An alternative sizing method is the Summation Method which considers a summation of the pressure losses through
each section of piping. is procedure is utilized for the designer whose requirements are not satisfied by the previously
described methods. e summation method can be used for system pressures and pressure drops other than indicated in
the sizing tables for longest run. is method allows full use of the maximum flow capacity of CSST. In this fashion, a
designer can minimize piping size (or maximize flow capacity) with greater accuracy in more complicated arrangements.
e summation method is shown in Examples 8 & 9.

3.1.7 MODIFYING AN EXISTING SYSTEM

XR3-series fittings transition from CSST to pipe thread (NPT) and may be run in conjunction with all other approved
fuel gas piping (iron pipe, polyethylene tubing, copper tubing, etc.). When adding appliances to an existing system the
installer must verify whether the existing system, upstream of the lines to be added, can support the additional load.

A retrofitted line, even when properly sized, added to a system that can’t support the additional load, can adversely effect
all the other appliances in the system.

When the existing system will not support the additional load several installation options exist. A new trunk line(s) can be
run replacing the under-sized system upstream of the retrofitted appliances. A dedicated trunk line can be run from the gas
source to the new appliance. e system pressure may be elevated, thus increasing the allowable pressure drop, after which
the existing trunk lines may afford sufficiently higher flow capacity to handle the existing and new appliances.

If the piping is visible or the existing run lengths are known, the entire system can be resized using either aforementioned
sizing method (Longest Run or Summation). e system shall be resized with an appropriate sizing table based on the
affordable pressure drop. When the piping is not visible or accessible for measurement, approximated lengths should be
rounded up.

3.2 SIZING PROCEDURES AND EXERCISES

3.2.1 SIZING EXAMPLES

While the following examples show typical applications of the sizing methods they do not address all of the system
configurations in which they can be used. In general, Longest Run and Summation can be used with any pressure or
system configuration (series, parallel, dual-pressure, hybrid, etc.).

e following exercises illustrate various design layouts, pressure drops and sizing methods. To further highlight the
differences in methods and designs, examples 1-8 use the same appliance layout and load.

3.2.2 EXAMPLE 1: SERIES SYSTEM – 6"WC

Figure 3-9 below shows a typical single-family house installation with five (5) appliances. e piping is arranged in series
with a main run branching at the appliances. e utility company’s supply pressure (downstream of the meter) is 6"WC.
e utility company advises that the specific gravity of the gas delivered will be 0.60 and the energy content is 1 CFH =
1000 BTUH. e allowable pressure drop across the system has been determined to be 1.0"WC (supply pressure 6"WC –
appliance requirement 5"WC).

SECTION 3: SYSTEM CONFIGURATION / JANUARY 2019

3.2.4 EXAMPLE 3: PARALLEL SYSTEM – 12-14"WC

Figure 3-11 below shows the same house and piping system as Example 2. e piping is arranged in parallel fashion,
with individual CSST appliance runs supplied by a main distribution manifold. e utility company’s supply pressure
(downstream of the meter) is 12-14"WC. e utility company advises that the specific gravity of the gas delivered will be

0.60 and the energy content is 1 CFH = 1000 BTUH. e allowable pressure drop across the system has been determined

to be 7"WC (supply pressure 12"WC - appliance requirement 5"WC). As there is no 7"WC pressure drop chart available
we must use the next lowest chart: in this case the 6"WC pressure drop chart (Table 7-8).
