USING THIS MANUAL

1. This boiler must be installed by a qualified contractor•

E. The boiler warranty can be voided if the boiler is not

installed, maintained and serviced correctly.

1. For new and existing installations, a Steam Installation Survey is available from Peerless Heater Company• 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•

2. 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 Peerless representative.

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.

i. We have provided suggested piping diagrams which will

cover most applications of this boiler.

2. Follow these guidelines to make sure the boiler will operate correctly. Pay close attention to pipe sizing and

location of risers and returns.

]+This manual provides wlrmg diagrams and lighting

instructions for standard systems only.

2 Use the Lighting Instructions and Wiring Diagrams

provided with the boiler to make sure they represent fire controls provided

I. Throughout this manual you will see special attention

boxes intended to supp]enrent the instructions and make special notice of potential hazards. These categories

mean, in the judgment of Peerless Heater Company:

Indicates special attention is needed, but not related to potential personal injury or

property damage.

Indicates a condition or hazard which will or can cause minor

personal injury or property damage.

Indicates a condition or hazard which could cause severe

personal injury, death or major property damage.

Indicates a condition or hazard

Figure 1: Clearance Requirements

I The following recommendations allow for reasonable

access to the boiler Local codes or special conditions

may require greater clearances•

•

a) For servicing the boiler: provide 48" between tile

conh'ol manifold and adjacent wall or other appliance

b) For access to draft hood or passage to access the boiler 4

control manifold(s): provide 48" between the side of the boiler and adjacent wall or other appliance.

c) See Figure 1, Clearances with an "S" are minimum

clearances for service accessibility. 5.

1. This boiler is design certified for the following clearances to combustible construction.

a 24" between the front, sides and rear of the jacket

• 6" from steam and hot water pipes

• 6" from vent connector a See Figure I. Clearances with a "C" indicate

minimum clearances from combustible construction•

1. The installation must provide adequate air for

combustion, ventilation and draft hood dilution•

2. Provide air openings as recommended below• The

lower opening provides combustion air and dilution air. The upper opening provides proper air circulation

to control the boiler room temperature and air quality• Without the upper opening, the boiler room

temperature will be too high, causing problems with control operation and life

The boiler room must never be under negative pressure.

Ifexhaust fans or other equipment can cause a negative pressure in the boiler room, the air openings and equipment design must be engineered to assure a neutral or slightly positive pressure in the boiler room at all times of operation If the equipment design and air openings

cannot assure this, then the boiler must be located in an isolated room.

The following recommendations are in accordance with the current edition of the National Fuel Gas Code, ANSI

Z223. I/NFPA54. Ifall air for combustion and ventilation comes from inside

the building (Figure 2), the building must have adequate

provision for outside air to assure the air supply needed

for the boiler room. Provide openings as follows:

• Provide two openings:

--one starting no closer than 3 inches nor further than 12 inches from the ceiling

one starting no closer than 3 inches nor further than

12 inches from the floor

• The openings must be into areas which have unrestricted access to outside air

• Each opening must have a free area (after deduction for louvers) of at least One square inch per 1000

Btu/Hr of total boiler and other appliance input. The openings must never be smaller than 100 square

inches each.

• If air is supplied through horizontal ducts (Figure 5), each opening must have a free opening (after louver

reduction) of at least One square inch per 2000 Btu/Hr of total boiler and other appliance input. The cross

sectional area of the ducts must be at least as much as the free area of the openings to which they connect.

7. Using combustion air dampers: a) If motorized dampers are used on the combustion

and ventilation air openings, wire them such that they must open when the boiler tries to operate.

They must include a switch which prevents the boiler

from operating if they do not open.

Figure 4: Air Openings - All Air from

Outdoors through Vertical Ducts

Inspect the existing chimney or vent system. Make sure it is in good condition. Inspect chimney liner and repair or replace if necessary.

The vent system and installation must be in accordance with Part 7, Venting of Equipment, of the current edition

of the National Fuel Gas Code, ANSI Z223.1/NFPA54, or applicable provisions of the local building codes.

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.

Failure to provide adequate

venting can result in severe

injury or death.

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 I0 feet above the bottom of the draft hood (relief opening). The vent must also extend above the roof or any obstiructions as outlined in the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA54 or as required by local codes.

b) Combined vent- breeching:

• The recommended sizing in Section 14, "Boiler

Ratings and Dimensions", in this Manual is based on a minimum chimney or vent height of 20 feet

and a maximum horizontal run of 6 feet 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 6): a) Provide at least a three foot rise in the vent

connection on the boiler.

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

0.02" w.c. measured at the vent connections.

c) Support the weight of the vent system indepently of

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

d) Provide support ofthe vent connector (breeching] at

maximum 12 foot intervals to prevent sagging and to provide a minimum upward slope of I/4" per foot.

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.

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.

Recommendedsizingfor chimneyand connectorsis based on maximum 6 foot connectorlength and

maximumone 90 degree elbow.

Figure 6: Vent Connection

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 orpipe.

f) After it has been determined that each appliance

remaining connected to the common venting system propedy 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/NFPA54. 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

ofthe National Fuel Gas Code, ANSIZ223.1/NFPA54.

3. PLACE THE BOILER SECTIONS

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 I'16".

2 Check the area around the Flow Ports (Figure 14). Use

solvent and a clean cloth to thorougly clean the flat surfaces and recesses• All foreign matter must be

removed to assure a proper seal when the sections are

drawn together•

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.

I. 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 15.

Figure 15: Placing the First Section on Base

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•

The sections are heavy and

must be supported securely•

Align the parting line of the section with the seam between the Base End panel and the Base Front Panel as shown in Figure 13.

Apply Hi-Temp rope seal by spreading a thin coat of RopeAdhesive 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 _/' beyond the top and bottom.

Place the Flow Port Gaskets in the recesses provided (see Figure 14). Do not use adhesive.

The following steps must be followed to insure that no

damage is done to the tie rod lugs. A 0 100 ft.-Ibs, 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 lugson each section

and app}y 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 16). Make sure they are square with the Base

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.

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 13.

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 17A. The placement order is left to right (Figure

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.

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

Provide a water supply line to the boiler. Plug all open tappings in the boiler.

Provide a means to vent air as the boiler fills. Fill the boiler with water, venting air as water level rises.

Pressurize boiler to 45 psig. Do not exceed this

plregsulre

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.

4. INSTALL THE FLUE COLLECTOR

1. ColDct the l:lu_' Coikzctor cartons. The Flue Cdlactot sections are ]abal_,d on tile part and on the carton See HiTempRope AngleBracket,

Table 4 for the items needed. GG-50O5

2. Install Hi Tamp Rope for each collector section asshown in Figure 18. The rope provides the seat to prevent flue gases from leaking from the collector. Make certain that

the rope is well under the bottom edges of each flue collector section in order to obtain a tight sea].

3. Place the Flue Collector sections in the positions given in Table 4. These positions are numbered from left to

right when facing the front of the boiler•

4. Fasten an angle bracket, part number GO-5005, to the top of each Collector section with two #10- Vi' sheet

metal screws. See Figure 19.

5. Insert a Long Hook Bolt, part number 00-5003, through the angle bracket Slip the hook end over the tie rod. Apply a W'-20 hex nut on the end of the rod and snug

against the bracket. See Figure 19. Do not tighten yet.

6. Insert a Short Hook Bolt, part number GO-5004, through

the flange in the rear of the flue collector. Catch the hook around the spacer pads at the top of the boiler sections. Apply a V4"-20 hex nut on the Bolt and snug against the flange. See Figure 19. Do not tighten yet.

7. Draw the Flue Collector sections tight against the sealing rope by tightening the nuts on the Hook Bolts. Draw the nuts evenly, alternating tightening.

5. PIPE THE BOILER

1 The boiler must be pressure tested as outlined in

Chapter 3. "Place the Boiler Sections", of this manual

2 TheSupplyandReturnpipingcanbeinstalledbeforethe

jacket is applied. Use nipples long enough to be sure they

will extend through the jacket.

1 Install End Riser connections sized per Table 5. The 3"

tappings in the tops of the end sections are not used for

steam boilers.

a) Install a reducing tee on one end riser. Install a 2"

valve, nipple and cap for skimming the boiler in the tee as shown in the piping drawings.

2. Models 211A-08 and larger require risers in both end sections.

3. Models 211A-18 and larger require additional 3" risers off of the tapped intermediate sections. See Table 5 for the number required.

4 Pipe the header at least 24 inches above the normal

boiler water line. This is required to prevent water from carrying over into the header and then to the system.

5 Figure 21 shows the Supply and Return piping for

Parallel Fk_w Gravity systems and all Pumped Return Systems.

6. Counterflow Gravity systems require the boiler steam line to enter the top of the steam main. See Figure 22 for this

special case.

Steam Supply

10.

11.

The piping in [hese drawings is shown off the right hand side of the boiler The boiler may also be piped toward the left side as shown in Figure 23, typical.

Do not reduce the size or number of risers shown

These are required for reliable operation of the boiler. If the risers are undersized or incorrectly placed, a sloped water line can occur in the boiler, causing possible overheating of some sections.

Pipe the Header with an offset as shown in the drawings. This offset prevents the expansion and contraction of the Header from damaging the boiler

sections.

Always locate the Steam Supply take-off between the Equalizer and the last Boiler Riser. (See

Peerless Heater Company's "Steam installation Survey" for discussion). Locating the Steam Supply between the risers will cause water carryover to the system.

Do not use a bull head tee to provide steam supply and equalizer connections. This will cause water level bounce and carryover.

We recommend the use of a Hartford loop in all

installations. The loop provides additional reliability for

the system. A check valve must still be installed on the

pump discharge of all pumped return systems. On pumped return systems, install a boiler cock after the

pump to allow throttling of the pump discharge. The pressure after the boiler cock should be no more than 5

psig above the boiler operating pressure. Pumping the

Steam Supply should always be piped between last boiler

riser and equalizer.

2. Provide separate feed lines for multiple boiler pumped

return systems• Use eithez separate feed pumps or solenoid valves to isolate feeding of the boilers. This is

needed to provide reliable level control and avoid nuisance performance problems.

3. Condensate return units are not effective for multiple

boiler installations since they do not respond to the needs of the boilers• Always use Boiler feed units•

a) Install a Float and Thermostatic trap at the boiler

water level on each of the multiple boilers on a pumped return system. This prevents flooding of idle

boilers due to condensation of steam•

water into the boiler too fast will cause collapse of the water level and level control problems

3. Size the equalizer per Table 5.

4, Pipe the Hadford loop tee so the inside top of the close

nipple is 2 to 4 inches below the boiler water line.

5. If the pump discharge is looped overhead• above the

boiler water line, install spring-loaded check valves at both the pump discharge and the connection to the boiler

return.

Size the piping as required by the National Fuel Gas Code. ANSI Z223 1,_FPA54 or as required by local

codes

a) Use Table {4 for sizing of natural gas for a system

pressure drop of 0 3 inch water column

The standard gas train is designed for a Maximum pressure of _/2psig (14 inches water column) Make sure the system regulator will not allow a higher pressure to the Gas Control Train under any conditions

The Minimum gas supply pressure is listed on the Boiler

Rating Plate. Make sure the system regulator and the piping are sized and adjusted properly to provide this pressure under all conditions.

Install a Service Valve. Sediment Trap and Ground Joint Union at the supply connection to the Gas Control Train as shown in Figure 30. These are not supplied with the

boiler. Install them in accordance with local codes.

Use only pipe joint compounds rated for use with Liquefied Petroleum Gases.

1. ISOLATE THE BOILER GAS CONTROL TRAIN FROM

THE SYSTEM DURING TEST: a) Test pressure _/bpsig or less - Close the Manual

Shut-Off Valve on the Boiler Gas Control Train

b) Test pressure over _/5psig Disconnect the gas

supply piping upstream of the Boiler Manual Shut-Off Valve

Do not expose the Gas Control Train to excessive pressure. The gas valves can be

damaged. This could result in

explosion hazard and severe

personal injury or death.

Do not test gas supply piping with open flame. Use a soap suds mixture brushed onto the

pipe joints to test for leaks.

Mount the float type Low Water Cutout and Gauge Glass in the tappings provided in the front of either end section.

Do not apply piping which would raise or lower the location of the cutout relative to the tappmgs in the boiler. Raising the water level over the design height will cause water carryover to the system.

For correct location of typical low water cutout!feeder or low water cutout/pump control, see Figures 33 through

36. Mount the probe type low water cutout supplied with the

boiler. The end sections have %" tappings in the front for mounting the probe low water cutout auxiliary control. See Figure 13.

a) The standard probe control is either the Hydrolevel

Model 650P or McDonnell & Miller Model PS850. These controls are automatic reset type.

b) When a manual reset control is required, the boiler

can be supplied with either the Hydrolevel Model 550P or the McDonnell & Miller Model PS850M.

Provide each float low water cutout with a blowdown valve. Pipe the blowdown away from traffic to a floor drain if available• The blowdown valve is required for

proper maintenance of the control. Maintain a height of 40 Vi' from boiler foundation to the

normal water level. When using Multiple Float Type Controls: Always pipe

the controls off of the same tappings to the boiler. Do not mount on different ends of the boiler or in different

tappings. This can cause erratic operation and nuisance problems with the controls.

Pipe the Steam Pressure Gauge and Boiler Lim:,t and Operating Pressure Controls as shown in Figure 32. Connect the control assembly to the Vi' tapping on the

right end of the boiler.

Make sure that the gas ignition system components, electrical controls, junction boxes and

electrical panels are protected

from water (dripping, spraying,

rain, etc.) during boiler operation and service (trap servicing, control replacements

or other).

boiler wateL producing an unstable water line and water carryover to the system.

Cleaning the boiler requires the use of very hot water and

corrosive chemicals. Use care when handling to prevent injury.

The piping for a skim valve must be done as shown in Section 5, "Pipe the Boiler", of this manual, with the skim valve mounted off of one of the end riser connections

Connect a 2 inch drain line off of the skim valve, run to a point of safe discharge.

Close all valves to the system. Provide a means of continuous fresh water to the boiler for the cleaning

process.

Open the skim valve. Fill the boiler until water begins to flow out the valve.

Use common washing soda (such as Arm and Hammer Super Washing Soda). Mix the soda with water in a 10 quart pail and pour into the boiler through the safety valve tapping. Use a proportion of one (I) pound of washing soda for each 800 square feet EDR net boiler rating.

Do not leave the boiler unattended while firing.

Take great care not to allow the water level to drop below the bottom of the gauge glass

or to allow fresh water make up to flow in too fast, This will

avoid the possibility of causing the boiler sections to fracture.

a) Lower the setting of each control until the burners

shut down.

2 Low Water Cutouts

a) Lower the water level in the boiler to below the

control cutout level. The burners should shut down.

3. Main Burner Shut-Off Valve(s) a) Close Main Burner Shut-Off Valve(s). b) The burners should shut down.

4. Check all controls to make sure they function correctly.

5. After all controls have been proven, set the Operating and

Limit Pressure ConlTols to the pressures desired.

I Clean the boiler as described below no later than one

week after the initial start-up. Cleaning will be more effective if the boiler operates a day or two to loosen

sediment and impurities in the system.

Turn burners on and allow the boiler water to heat up to just below steaming (180 to 200 OF), Cycle the burners to maintain temperature during skimming. Do not allow

the boiler to steam. Steaming mixes up the contaminants

in the water instead of floating them at the surface. Open the make-up water valve to continuously feed

water to the boiler. Allow water to flow out of the skim tapping.

Continue skimming the boiler until the water flowing from the skim tapping flows clear. This will take some time, possibly several hours for a dirty system.

After skimming is complete, close the skim valve and turn off the boiler.

Close the make*up water valve and open the boiler blowdown valves.

Drain the boiler completely. Then refill and drain again

one or two times to make sure all of the soda has been washed out.

Restore piping to normal. Pipe a nipple and cap in the

skim valve.

Note: If the gauge glass becomes dirty again, this indicates more contaminants have worked loose in the

system. Repeat the cleaning and skimming process as needed to clean the system.

nlanual.

f) Remove the burners and brush the gas ports lightly

with a soft bristle brush.

5. Inspect the boiler base and insulation.

6. Inspect the boiler and piping for signs of leaks. Check to see if there are signs of heavy make-up water addition to

the system.

7. When placing boiler into operation, follow Lighting Instructions shipped with the boiler and the instructions

in this Chapter.

F, Test the operation of all limit conh his float conhols and

igntion components as described in Pa_t A. *Placing Boiler in Operation", of this Chaptel

1. Inspect the burner and pilot flames as fol the annual inspection.

2 Inspect the boiler and system for any signs of leakage or

excessive make-up water usage

3. Inspect and check the operation of the venting system.

1. Blow down the float type low water cutouts and test for correct operation.

1. Inspect the boiler area to make sure the area is free from combustible or flammable materials and that there are

no obstructions to the flow of air to the boiler or

combustion air openings to the room

2. Make sure there are no signs of abnormal operation, such as overfilling or leakage.

Be very careful when adding water to a hot boiler. Add

very slowly or, if possible, allow the boiler to cool

naturally before adding water.

If an excessive loss of water occurs, check for a leak in the piping and correct the problem. Excessive make-up

water will cause corrosion and damage to the boiler.
