PREINSTALLATION

2. Required Combustion Air Volume: The total required volume of indoor air is to be the sum of the required volumes for all appliances located within the space. Rooms communicating directly with the space in which the appliances are installed and through combustion air openings sized as indicated in Subsection 3 are considered part of the required volume. The required volume of indoor air is to be determined by one of two methods.

a. Standard Method: The minimum required

volume of indoor air (room volume) shall be 50 cubic feet per 1000 BTU/Hr (4.8 m

/kW). This method is to be used if the air infiltration rate is unknown or if the rate of air infiltration is known to be greater than 0.6 air changes per hour. As an option, this method may be used if the air infiltration rate is known to be between 0.6 and

0.4 air changes per hour. If the air infiltration rate is known to be below 0.4 then the Known Air Infiltration Rate Method must be used. If the building in which this appliance is to be installed is unusually tight, PB Heat recommends that the air infiltration rate be determined.

b. Known Air Infiltration Rate Method:

Where the air infiltration rate of a structure is known, the minimum required volume of indoor air for appliances other than fan assisted and for the Series 211A Boiler shall be determined as follows:

where:

other

= Input of appliances other than fan

assisted in Btu/hr

ACH = air change per hour (percent of the

volume of the space exchanged per hour, expressed as a decimal)

For fan assisted appliances, calculate the required volume of air using the following equation:

fan

= Input of the fan assisted appliances in

Btu/hr

Note: These calculations are not to be used for infiltration rates greater than 0.60 ACH.

3. Indoor Air Opening Size and Location:

(645 cm2). One opening is to begin within 12 inches (305 mm) from the top of the space and the other is to begin within 12 inches (305 mm) from the floor. The minimum dimension of either of these openings shall be 3 inches (76 mm). See Figure

1.2 for an illustration of this arrangement.

b. Combining spaces on different floors:

Provide one or more permanent openings communicating with additional spaces that have a total minimum free area of 2 in

per 1000

Btu/hr (44 cm

per 1000 W) of total input rating of all equipment. See Figure 1.3 for an illustration of this arrangement.

4. Outdoor Combustion Air:

Outdoor combustion air is to be provided through one or two permanent openings. The minimum dimension of these air openings is 3 inches (76 mm).

a. Two Permanent Opening Method: Provide

two permanent openings. One opening is to begin within 12 inches (305 mm) of the top of the space and the other is to begin within 12 inches (305 mm) of the floor. The openings are to communicate directly or by ducts with the outdoors or with spaces that freely communicate with the outdoors. The size of the openings shall be determined as follows:

d. In buildings where the combustion air is provided

by the mechanical ventilation system, the system shall provide the specified combustion air rate in addition to the required ventilation air.

8. Louvers & Grills:

a. The required size of openings for combustion,

ventilation, and dilution air shall be based on the net free area of each opening.

i. Where the free area through a louver or grille

is known, it shall be used in calculating the opening size required to provide the free area specified.

ii. Where the free area through a louver or grille

is not known, it shall be assumed that wooden louvers will have 25% free area and metal louvers and grilles will have 75% free area.

iii. Nonmotorized dampers shall be fixed in the

open position.

b. Motorized dampers shall be interlocked with the

equipment so that they are proven in the full open position prior to ignition and during operation of the main burner.

i. The interlock shall prevent the main burner

from igniting if the damper fails to open during burner startup.

ii. The interlock shall shut down the burner if

the damper closes during burner operation.

9. Combustion Air Ducts

a. Ducts shall be constructed of galvanized steel or

an equivalent corrosion- resistant material.

b. Ducts shall terminate in an unobstructed space,

allowing free movement of combustion air to the appliances.

PREINSTALLATION

3. Chimney/Vent Operation: The vent system must be sized and installed to provide the draft needed to remove all combustion products. If the vent system does not provide enough draft, combustion products will spill into the building from the draft hood relief opening. If spillage of combustion products occurs, check the vent system, the combustion and ventilation openings and make sure the boiler room is never under negative pressure.

4. Exterior Vents

a. If the vent is outside, make sure it is insulated

sufficiently to ensure adequate draft.

5. Vent Sizing:

a. Individual vents: Use vent piping the same

diameter as the boiler vent connection. The minimum height is 10 feet (305 cm) above the bottom of the draft hood (relief opening). The vent must also extend above the roof or any obstructions as outlined in the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CGA B149, Installation Codes or as required by local codes.

b. Combined vent breeching:

• The recommended sizing in Section 14, Boiler Ratings & Dimensions, in this Manual is based on a minimum chimney or vent height of 20 feet (610 cm) and a maximum horizontal run of 6 feet (183 cm) to the chimney with no more than one 90-degree standard elbow.

• The minimum area of the chimney serving two or more appliances must be at least the area of the largest chimney connector plus 50% of the total area of all other appliance connectors.

• The vent connector must be single wall steel or Type B double wall vent pipe. The vent connector must be Type B double wall if it is located in or passes through cold areas. The vent connector must extend into, but not beyond, the inside wall of the chimney.

6. Vent Connection to Boiler (Figure 1.8): a. Provide at least a 3 foot (91 cm) rise in the vent

connection on the boiler.

b. The vent system should provide a draft of at least

0.02" w.c. (5 Pa) measured at the vent connections.

c. Support the weight of the vent system

independently of the boiler draft hood. The draft hood is not designed to carry structural loading.

d. Provide support of the vent connector

(breeching) at maximum 12 foot (366 cm) intervals to prevent sagging and to provide a minimum upward slope of 1/4" per foot (21 mm per meter).

e. Do not connect the vent for this boiler into any

vent system which operates with positive pressure.

f. Use Type B double-wall pipe for vents which run

through unheated spaces.

7. Removing an existing boiler from a common vent:

At the time for removal of an existing boiler, the following steps shall be followed with each appliance connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.

a. Seal any unused openings in the common

venting system.

b. Visually inspect the venting system for proper size

and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.

c. Insofar as is practical, close all building doors

and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

d. Place in operation the appliance being inspected.

Follow the lighting instructions. Adjust the thermostat so appliance will operate continuously.

e. Test for spillage at the draft hood relief opening

after 5 minutes of main burner operation. Use the flame of a match or candle, or smoke from a cigarette, cigar or pipe.

Failure to provide adequate venting can result in severe property damage, personal injury or death.

WARNING

Figure 1.8: Vent Connection

PREINSTALLATION

f. After it has been determined that each appliance

remaining connected to the common venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas-burning appliance to their previous condition of use.

g. Any improper operation of the common venting

system should be corrected so the installation conforms with the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CGA B149, Installation Codes. When resizing any portion of the common venting system, the common venting system should be resized to approach the minimum size as determined using the appropriate tables located in the chapter Sizing of Category I Venting Systems in the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CGA B149, Installation Codes.

E. BOILER SETTING

1. Provide a good, level foundation for the boiler with the minimum dimensions given in Figure 1.9 and Table 1.1. The flooring and structural support system must be suitable for the operating weight of the boiler and any connected piping.

2. Do not operate the boiler until the foundation, if new concrete, has thoroughly cured. The high temperature under the burners could cause major damage to the concrete if it still contains moisture.

3. If the boiler is installed in a penthouse or if wiring of any sort is run underneath the boiler foundation, construct the foundation with provision for airflow underneath between the main floor and the top of the boiler foundation.

a. Concrete block aligned with the openings

connected continuously would serve this purpose, for example.

b. If the foundation must be a concrete slab, use an

air cell high temperature insulating board, at least 1/2 inch (13 mm) thick, with aluminum backing, aluminum side up. One-half inch (13 mm) Hi Temp millboard with aluminum backing would be acceptable as well. Place the insulating board on the slab inside the base.

F. WATER QUALITY AND MAKE-UP

1. Check the system to make sure there are no leaks or overfilling problems which might cause excessive make-up water to be added. Make-up water causes liming in the boiler and brings in oxygen. Oxygen can cause severe damage to the boiler through oxygen corrosion pitting.

2. Clean the boiler as described in this manual. Poor water quality will cause foaming, priming and overfilling of the system. Too much sediment in the water will cause build-up in the boiler and could result in cracked sections due to overheating.

3. If the condensate return time lag is too long, this boiler may not work correctly with gravity return or with a condensate return unit. Long time lags will cause make-up water to be added to the boiler, resulting in flooding of the boiler, carryover to the system and excessive make-up water addition. You will need to install a boiler feed system to prevent problems in such cases.

4. Do not use chemicals or substances in the

boiler or system which contain petroleum or its derivatives. This will damage the boiler seals.

G. INSTALLATION SURVEY

For new and existing installations, a Steam Installation Survey is available from PB Heat. The survey will provide information on how a steam boiler works with your specific system and will provide an overview of steam system operation in general.

You can also use this survey to locate system problems which will have to be corrected. To obtain copies of the Steam Installation Survey, contact your PB Heat representative or download from PeerlessBoilers.com.

PLACE THE BOILER SECTIONS

A. PREPARATION

1. Check the level of the Boiler Base using a spirit level. Make sure the base is level and that the base panels are aligned within plus or minus 1/16" (2 mm).

2. Check the area around the Flow Ports (Figure 3.1). Use solvent and a clean cloth to thoroughly clean the flat surfaces and recesses. All foreign matter must be removed to assure a proper seal when the sections are drawn together.

B. PLACING THE SECTIONS

1. Begin by placing the Left Hand End Section on the left end of the base. The upper flow port goes toward the front of the boiler as shown in Figure 3.2.

2. Slide the section to the back of the base until the cast lug on the bottom of the section under the lower flow port is against the base back panel. Keep the section upright by a supporting prop or other means.

3. Align the parting line of the section with the seam between the Base End panel and the Base Front Panel as shown in Figure 3.3.

4. Apply Hi-Temp rope seal by spreading a thin coat of spray adhesive in the grooves on each end of the section. Place the rope in the grooves. Do not stretch the rope. The longer rope goes in the front groove. NOTE: The ends of each rope must extend 1/2" (13 mm) beyond the top and bottom.

5. Place the Flow Port Gaskets in the recesses provided (see Figure 3.1). Do not use adhesive.

6. The following steps must be followed to insure that no damage is done to the tie rod lugs. A 0-100 ft.-lbs. (0-136 N

m) torque wrench is required.

a. Place an Intermediate Section on the base and

slide it carefully against the Left Hand End Section.

b. Align the flow ports from front to back, as close

as possible.

c. Insert a tie rod into each of the lugs on each

section and apply a nut and washer to each end of the tie rod.

d. Before tightening, check the vertical alignment of

the sections using a spirit level (see Figure 3.4). Make sure they are square with the Base.

3. PLACE THE BOILER SECTIONS

Gaskets will be damaged by petroleum or its derivatives. Completely remove all solvent residue before placing gaskets.

Do not use petroleum based compounds in the boiler.

CAUTION

The sections are heavy and must be supported securely.

WARNING

Figure 3.1: Flow Port Machining & Gasket

Figure 3.2: Placing the First Section on Base

Figure 3.3: Assembling Sections on Base

PLACE THE BOILER SECTIONS

e. Draw sections together evenly, alternating

between top lug and bottom lug in increments of 20 ft.-lbs. (27 N

m). Continue until both top and

bottom lugs are tightened to 60 ft.-lbs. (81 N

m).

DO NOT EXCEED 60 FT.-LBS (81 N

m).

f. Check the level while tightening to make sure

alignment stays true. Also make sure sections remain square with the Base from front to back as the tie rods are tightened and as additional sections are installed.

g. If the sections tend to run out of plumb, this will

usually be at the bottom front. Loosen the upper nuts slightly and tighten the lower ones to adjust.

7. Assemble the remaining sections in the same way for a finished assembly as shown in Figure 3.3.

8. Some of the Intermediate Sections have tappings for installing additional steam risers from the boiler. These Tapped Intermediate Sections must be installed as shown in Figure 3.5A. The placement order is left to right (Figure 3.5).

C. HYDROSTATIC TEST THE BOILER

1. The supply and return piping can be permanently erected before applying the Boiler Jacket if the pipe nipples applied to the boiler tappings are long enough to clear the jacket.

2. Install a drain cock in the tapping provided at the bottom rear of each end section.

3. Provide a water supply line to the boiler.

4. Plug all open tappings in the boiler.

5. Provide a means to vent air as the boiler fills.

6. Fill the boiler with water, venting air as water level rises.

7. Pressurize boiler to 45 psig (310 kPa). Do not exceed this pressure.

a. Maintain pressure while checking all joints and

fittings for leaks.

b. After inspection is complete, drain the boiler and

remove plugs from tappings that are to be used.
