I. Pre-Installation

WARNING

Carefully read all instructions before installing boiler. Failure to follow all instructions in proper order can cause personal injury or death.

A. Inspect shipment carefully for any signs of damage.

All equipment is carefully manufactured, inspected and packed. Our responsibility ceases upon delivery of boiler to carrier in good condition. Any claim

for damage or shortage in shipment must be led

immediately against carrier by consignee. No claims for variances or shortages will be allowed by Boiler Manufacturer, unless presented within sixty (60) days after receipt of equipment.

B. Installation must conform to the requirements of the

authority having jurisdiction. In the absence of such requirements, installation must conform to National Fuel Gas Code, ANSI Z223.1/NFPA 54. Where required by the authority having jurisdiction, the installation must conform to the Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.

C. Appliance is design certied for installation on

combustible ooring. The boiler must not be installed

on carpeting.

D. Provide clearance between boiler jacket and

combustible material in accordance with local re

ordinance. Refer to Figure 1 for minimum clearance from combustible material for alcove installation. Provide 1/2" clearance from water piping to combustible materials.

E. Provide practical service clearances. A minimum

of 24" from the right side and front jacket panels is recommended for servicing but may be reduced to minimums shown in Figure 1.

F. Install on level oor. For basement installation provide

concrete base if oor is not level or if water may be encountered on oor around boiler.

G. Protect gas ignition system components from

water (dripping, spraying, rain, etc.) during boiler operation and service (circulator replacement, control replacement, etc.).

H. Provide combustion and ventilation air in accordance

with the section "Air for Combustion and Ventilation," of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or applicable provisions of local building codes.

WARNING

Adequate combustion and ventilation air must be provided to assure proper combustion.

The following guideline is based on the National Fuel

Gas Code, ANSI Z223.1/NFPA 54.

1. Determine volume of space (boiler room). Rooms communicating directly with space (through openings not furnished with doors) are considered part of space.

Volume [ft³] = Length [ft] x Width [ft] x Height [ft]

2. Determine Total Input of all appliances in space. Round result to nearest 1,000 Btu per hour (Btuh).

3. Determine type of space. Divide Volume by Total Input.

a. If result is greater than or equal to 50 ft³ per

1,000 Btuh, space is considered an unconned space.

b. If result is less than 50 ft³ per 1,000 Btuh, space

is considered a conned space.

4. Determine building type. A building of unusually tight construction has the following characteristics:

a. Walls and ceiling exposed to outside atmosphere

have a continuous water vapor retarder with a rating of 1 perm or less with openings gasketed and sealed, and;

b. Weather-stripping has been added on openable

windows and doors, and;

c. Caulking or sealants applied in joints around

window and door frames, between sole

plates and oors, between wall-ceiling joints,

between wall panels, at plumbing and electrical penetrations, and at other openings.

5. For boiler located in an unconned space in a building of other than unusually tight construction, adequate combustion and ventilation air is normally

provided by fresh air inltration through cracks

around windows and doors.

6. For boiler located within unconned space in building of unusually tight construction or within conned space, provide outdoor air through two permanent openings which communicate directly or by duct with the outdoors or spaces (crawl or attic) freely communicating with the outdoors. Locate one opening within 12 inches of top of space. Locate remaining opening within 12 inches of bottom of space. Minimum dimension of air opening is 3 inches. Size each opening per following:

I. Pre-Installation (continued)

a. Direct communication with outdoors. Minimum

free area of 1 square inch per 4,000 Btu per hour input of all equipment in space.

b. Vertical ducts. Minimum free area of 1 square

inch per 4,000 Btu per hour input of all equipment in space. Duct cross-sectional area shall be same as opening free area.

c. Horizontal ducts. Minimum free area of 1

square inch per 2,000 Btu per hour input of all equipment in space. Duct cross-sectional area shall be same as opening free area.

Alternate method for boiler located within conned

space. Use indoor air if two permanent openings communicate directly with additional space(s) of

sufcient volume such that combined volume of all spaces meet criteria for unconned space. Size each

opening for minimum free area of 1 square inch per 1,000 Btu per hour input of all equipment in spaces, but not less than 100 square inches.

7. Ventilation Duct Louvers and Grilles. Equip outside openings with louvers to prevent entrance of rain and snow, and screens to prevent entrance of insects

and rodents. Louvers and grilles must be xed in

open position or interlocked with equipment to open automatically before burner operation. Screens must not be smaller than ¼ inch mesh.

Consider the blocking effect of louvers, grilles and

screens when calculating the opening size to provide the required free area. If free area of louver or grille is not known, assume wood louvers have 20-25 percent free area and metal louvers and grilles have 60-75 percent free area.

I. Do not install boiler where gasoline or other

ammable vapors or liquids, or sources of

hydrocarbons (i.e. bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.) are used or stored.

II. Unpack Boiler

CAUTION

Do not drop boiler. Do not bump boiler jacket

against oor.

A. Move boiler to approximate installed position.

B. Remove all crate fasteners.

C. Lift outside container and remove with all other

inside protective spacers and bracing. Save two of the wooden slats from the container sleeve for use in Steps E and F.

D. Remove all boiler hold-down fasteners.

E. Tilt the boiler to one side and slide a wooden slat under

the two raised feet.

F. Tilt the boiler to the other side and slide another

wooden slat under the two raised feet.

G. Slide the boiler forward or backward off the skid using

the two wooden slats as runners.

H. Move boiler to its permanent location.

III. Water Piping and Trim

WARNING

appropriate valves to prevent chilled medium from entering boiler. See Figure 3.

Failure to properly pipe boiler may result in improper operation and damage to boiler or building.

A. Design and install boiler and system piping to

prevent oxygen contamination of boiler water.

Oxygen contamination sources are system leaks

requiring addition of makeup water, ttings, and

oxygen permeable materials in distribution system. Eliminate oxygen contamination by repairing system

leaks, repairing ttings, and using non-permeable

materials in distribution system.

B. Install circulator with anges, gaskets and bolts

provided.

C. Install Safety Relief Valve. See Figure 2. Safety Relief

Valve must be installed with spindle in vertical position.

WARNING

Safety relief valve discharge piping must be

piped near oor to eliminate potential of severe

burns. Do not pipe in any area where freezing could occur. Do not install any shut-off valves.

D. Connect system supply and return piping to boiler.

Refer to Figures 2, 3, 4, & 5. Maintain minimum ½ inch clearance from hot water piping to combustible materials.

E. If boiler is used in connection with refrigeration

systems, boiler must be installed with chilled medium

piped in parallel with the heating boiler using

F. If boiler is connected to heating coils located in

air handling units where they may be exposed to refrigerated air, boiler piping must be equipped with

ow control valves or other automatic means to prevent

gravity circulation of boiler water during operation of cooling system.

G. Use a boiler bypass if the boiler is to be operated

in a system which has a large volume or excessive radiation where low boiler water temperatures may be encountered (i.e. converted gravity circulation system, etc.).

Remove circulator and install pipe tee between

circulator and boiler return along with second tee in supply piping as shown in Figures 4 and 5. Bypass should be same size as the supply and return lines with valves located in bypass and supply outlet as illustrated

in Figures 4 and 5 in order to regulate water ow to

maintain higher boiler water temperatures.

Set by-pass and boiler supply valves to half throttle

position to start. Operate boiler until system water temperature reaches normal operating range.

Adjust valves to provide 180° to 200°F supply water

temperature. Opening the boiler supply valve will raise system temperature, while opening by-pass valve will lower system supply temperature.

H. If it is required to perform a long term pressure

test of the hydronic system, the boiler should rst be

isolated to avoid a pressure loss due to the escape of air trapped in the boiler.

To perform a long term pressure test including the

boiler, ALL trapped air must rst be removed from the

boiler.

A loss of pressure during such a test, with no visible

water leakage, is an indication that the boiler contained trapped air.

Figure 4: Recommended Water Piping for Zone Valve Zoned Heating Systems

III. Water Piping and Trim (continued)

Figure 5: Recommended Water Piping for Circulator Zoned Heating Systems

IV. Gas Piping

A. Size gas piping. Design system to provide adequate gas

supply to boiler. Consider these factors:

1. Allowable pressure drop from point of delivery to boiler. Maximum allowable system pressure is ½ psig. Actual point of delivery pressure may be less; contact gas supplier for additional information. Minimum gas valve inlet pressure is listed on rating label.

2. Maximum gas demand. Consider existing and expected future gas utilization equipment (i.e. water heater, cooking equipment).

B. Connect boiler gas valve to gas supply system.

1. Use methods and materials in accordance with local plumbing codes and requirements of gas supplier. In absence of such requirements, follow National Fuel Gas Code, ANSI Z223.1/NFPA 54.

2. Use thread (joint) compounds (pipe dope) resistant

to action of liqueed petroleum gas.

3. Install sediment trap, ground-joint union and manual shut-off valve upstream of boiler gas control valve. See Figure 6.

4. All above ground gas piping upstream from manual shut-off valve must be electrically continuous and bonded to a grounding electrode. Do not use gas piping as grounding electrode. Refer to National Electrical Code, ANSI/NFPA 70.

C. Pressure test. The boiler and its gas connection must

be leak tested before placing boiler in operation.

1. Protect boiler gas control valve. For all testing over ½ psig, boiler and its individual shutoff valve must be disconnected from gas supply piping. For testing at ½ psig or less, isolate boiler from gas supply piping by closing boiler's individual manual shutoff valve.

2. Locate leaks using approved combustible gas

detector, soap and water, or similar nonammable solution. Do not use matches, candles, open ames,

or other ignition source.

Figure 6: Pilot and Gas Piping

V. Venting

A. Install vent system in accordance with "Venting of

Equipment" of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or applicable provisions of local building codes. Install any of the following for this Force Series Category I, draft hood equipped appliance:

1. Type B or Type L gas vent. Install in accordance with listing and manufacturer's instructions.

2. Masonry or metal chimney. Build and install in accordance with local building codes; or local authority having jurisdiction; or Standard for

Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances, ANSI/NFPA 211.

Masonry chimney must be lined with approved clay

ue lining or listed chimney lining system.

3. Single wall metal vent. Allowed by ANSI Z223.1/ NFPA 54 under very restrictive conditions.

4. Do not use cellular core PVC (ASTM F891), cellular core CPVC, or Radel® (polyphenolsulfone).

5. Do not cover non-metallic vent pipe and ttings

with thermal insulation. Note: Non-metallic vent cannot be used with this boiler.

B. Inspect chimney and remove any obstructions or

restric tions. Clean chimney if previously used for solid

or liquid fuel-burning appliances or replaces.

DANGER

Inspect existing chimney before installing boiler. Failure to clean or replace perforated pipe or tile lining will cause severe injury or death.

C. Install Vent Damper

OPEN THE VENT DAMPER CARTON and remove the

Installation Instructions. READ THE INSTALLATION INSTRUCTIONS THOROUGHLY before proceeding.

The automatic gas control valve supplied on each

Force Series boiler provides the redundancy referenced in the vent damper Installation Instructions.

CAUTION

Do not use one vent damper to control two heating appliances.

1. The vent damper must be the same size as the outlet of the Draft Hood supplied with the boiler (see Table 1B). Unpack the damper carefully - DO NOT FORCE IT CLOSED! Forcing the damper may damage the gear train and void the warranty.

Figure 7: Vent Damper Installation

2. Mount the vent damper assembly onto the canopy/ diverter. (Refer to Figure 7 and to instructions

packed with the vent damper) for specic

instructions). Do not modify either the draft hood or vent damper.

NOTICE

Provide adequate clearance for servicing.

3. Locate vent damper position indicating means to be visible following installation.

WARNING

Provide 6" minimum clearance between damper and combustible construction.

4. Plug the factory harness vent damper connector into damper motor polarized receptacle.

V. Venting (continued)

D. Install Vent Connector

1. Install vent connector from vent damper outlet to chimney.

2. Vent connectors serving appliances vented by natural draft shall not be connected into any portion of mechanical draft systems operating under positive pressure.

3. Do not connect into same leg of chimney serving an

open replace.

4. Inspect chimney for obstructions or restrictions and remove. Clean chimney if necessary.

5. Vent pipe to chimney must not be smaller than outlet on draft hood or damper. Type B Vent Connector is recommended. The venting system must be arranged so that only the boiler is served by the damper device. Installation per paragraph (C) complies with this provision.

6. Vent pipe should have the greatest possible initial rise above the draft hood consistent with the head room available and the required clearance from adjacent combustible building structure. Vent Pipe should be installed above the bottom of chimney to prevent blockage.

7. Vent pipe should slope upward from draft hood to vent terminal not less than 1/4" per foot.

8. Support horizontal portions of venting system to prevent sagging. Use pipe straps, brackets or hangers spaced 4 ft. or less.

9. Vent pipe must be inserted into but not beyond inside wall of chimney liner. Seal tight between vent pipe and chimney.

10. Do not install non-listed (AGA, CGA, CSA, ETL or UL) vent damper or other obstruction in vent pipe.

WARNING

E. If an Existing Boiler is Removed:

When an existing boiler is removed from a common

venting system, the common venting system is likely to be too large for proper venting of the appliances remaining connected to it.

At the time of removal of an existing boiler, the

following steps shall be followed with each appliance remaining 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

deciencies 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 maxi mum speed. Do not operate a summer exhaust fan. Close

replace dampers.

d. Place in operation the appliance being inspected.

Follow the Lighting (or Operating) Instructions. Adjust thermo stat so appliance will operate continuously.

e. Test for spillage at the draft hood relief opening after

5 minutes of main burner operation. Use the ame

of a match or candle, or smoke from a cigarette, cigar or pipe.

f. After it has been determined that each appliance

remain ing connected to the common venting system properly vents when tested as outlined above, return

doors, win dows, exhaust fans, replace 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 National Fuel Gas Code, ANSI Z223.1/NFPA 54. 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 in Chapter 13 of the National Fuel Gas Code, ANSI Z223.1/NFPA 54.

VI. Electrical

A. General. Install wiring and electrically bond boiler to

ground in accordance with requirements of authority having jurisdiction, or in absence of such requirements, with the National Electrical Code, ANSI/NFPA 70.

B. Install thermostat. Locate on inside wall

approximately 4 feet above oor. Do not install on outside wall, near replace, or where inuenced by drafts or restricted air ow, hot or cold water pipes, lighting xtures, television, or sunlight. Allow free air

movement by avoiding placement of furniture near thermostat.

C. Wire boiler. Boiler is rated for 120 VAC, 60 hertz,

less than 12 amperes. A separate electrical circuit must be run from the main electrical service with an over-current device/disconnect in the circuit. A service switch is recommended and may be required by some local jurisdictions. Connect to L1, L2 and green ground screw. See Figures 8 and 9.

D. For installations using zone valves provide separate

transformer for zone valve wiring. Consult zone valve manufacturer for assistance.

CAUTION

This boiler contains controls which may cause the boiler to shut down and not restart without service. If damage due to frozen pipes is a possibility, the heating system should not be left unattended in cold weather; or appropriate safeguards and alarms should be installed on the heating system to prevent damage if the boiler is inoperative.

VII. System Start-up and Checkout

This boiler is equipped with a feature that saves energy by reducing the boiler water temperature as the heating load decreases. This feature is equipped with an override which is provided primarily to permit the use of an external energy management system that serves the same function. THIS OVERRIDE MUST NOT BE USED UNLESS AT LEAST ONE OF THE FOLLOWING CONDITIONS IS TRUE:

• An external energy management system is installed that reduces the boiler water

temperature as the heating load decreases.

• This boiler is not used for any space heating.

• This boiler is part of a modular or multiple boiler system having a total input of

300,000 BTU/hr or greater.

• This boiler is equipped with a tankless coil.

IMPORTANT

A. Main Burner Check - Check main burners to see

that they were not dislodged during shipment. Rear of burners should be in the vertical slots in the rear of burner tray and the front of the burners should be seated

completely on the orices.

B. Initial start -

1. Fill entire heating system with water and vent air from system. Use the following procedure on a System equipped with zone valves.

a. Close isolation valve in boiler supply piping.

b. Isolate all circuits by closing zone valves or

balancing valves.

c. Attach a hose to hose bib located just below

isolation valve in boiler supply piping. (Note

- Terminate hose in ve gallon bucket, at a suitable oor drain, or outdoor area).

d. Starting with one circuit, open zone valve.

e. Open hose bib.

f. Open ll valve (Make-up water line should be

located directly above isolation valve in boiler supply piping).

g. Allow water to overow from bucket until

discharge from hose is bubble free for 30 seconds.

h. Open zone valve to the second zone to be

purged, then close the rst. Repeat this step until

all zones have been purged, but always have one zone open. At completion, open all zone valves.

i. Close hose bib, continue lling the system

until the pressure gauge reads 12 psi. Close ll

valve. (Note - If make-up water line is equipped with pressure reducing valve, system will

automatically ll to 12 psi. Leave globe valve

open).

j. Open isolation valve in boiler supply piping.

k. Remove hose from hose bib.

2. Turn ROOM THERMOSTAT to lowest setting.

3. Be sure that gas to pilot and main burners has been

off for at least ve minutes and vent damper has

been in the open position.

4. Turn "OFF" the electric switch serving boiler.

5. Open valve on main gas line at meter.

6. PURGE AIR FROM GAS PIPING. Adequate

ventilation must be provided and no smoking or

open ame permitted.

7. Turn "ON" electric switch serving boiler.

8. Open Manual Shut-off Valve upstream of Combination Gas Valve.

9. Loosen or remove Inlet Pressure Tap Plug in Combination Gas Valve and when purging is complete, tighten or replace plug. (See Figure 10).

10. Check pipe and ttings from meter to Combination

Gas Valve using soap solution or other approved methods.

Figure 10: Top View of Honeywell Gas Valves

VII. System Start-up and Checkout (continued)

CAUTION

11. Test gas piping and connections between

Combination Gas Valve and manifold, orices, and

pilot piping for leaks after boiler is operating. Use soap solution or other approved method.

C. Check Gas Input to Boiler

1. Input Rate and Maximum Inlet Pressure shown on Rating Label must not be exceeded. Inlet pressure must not be lower than minimum inlet pressure shown on Rating Label.

2. All Rate checks and all adjustments are to be made

while boiler is ring - all other appliances connected

to the same meter as the boiler must be off.

3. With boiler off, water Manometer or water column gauge should be connected to a shut-off valve installed in the 1/8" outlet pressure tap in the gas valve (See Figure 10). By installing gas valve upstream of manometer, gas pressure can be introduced gradually - without shut-off valve; surge of pressure when boiler is turned on, could blow liquid out of manometer. Replace plug in gas valve

when rate check is nished.

4. LP Gas Input:

Adjust Regulator on Gas Valve so that manifold

pressure is 10 inches water column. Turning Regulator Adjusting Screw Clockwise increases pressure. Counterclockwise rotation decreases pressure.

5. Natural Gas Input

a. Approx. Input - Adjust regulator on Gas Valve

so that manifold pressure is 3½ inches water column. Turning Regulator Adjusting Screw Clockwise increases pressure, Counter-clockwise rotation decreases pressure.

Avoid operating this boiler in an environment

where saw dust, loose insulation bers, dry wall

dust, etc. are present. If boiler is operated under these conditions, the burner interior and ports must be cleaned and inspected daily to insure proper operation.

E. Check Pilot Burner Flame.

1. See Figure 12. The pilot burner should be lit only

Figure 11: 1 Inch Main Burner Flame

CAUTION

if thermostat is calling for heat. The pilot burner

produces three (3) ames. The center ame should

be steady, medium hard blue enveloping 3/8 to 1/2 inch of thermocouple.

D. Check Main Burner Flame. See Figure 11. Flame

should have a clearly dened inner cone with no yellow

tipping. Orange-yellow streaks caused by dust should not be confused with true yellow tipping.

Figure 12: Pilot Burner Flame

VII. System Start-up and Checkout (continued)

F. Check Ignition System Safety Shut-off Device.

Remove 3-wire plug from gas valve.

If burners do not shut down determine cause of

malfunction. Replace necessary items and check operation.

G. Check Vent Damper Operation. Vent Damper must

be in open position when main burners are operating.

H. Check High Limit Control.

Wiring Ladder Diagram

Terminal Number

Figure 14: Measuring Pilot Flame Current

with Micro-ammeter

b. Flame current must be measured with pilot

valve open/pilot lit but the main valve closed.

c. Disconnect MV lead wire from the module

before measuring ame current. Trying to measure the pilot ame current in series

with the wiring will not yield the accurate reading.

d. The minimum steady pilot ame signal

must be 1 μAmp (microampere) DC (direct current).

e. For reliable operation the ame current

should be 2 μAmp or greater.

f. To ensure adequate ame current:

i. Turn off boiler power at circuit breaker

or fuse box

ii. Clean the ame rod with emery cloth if

required

iii. Make sure electrical connections are

clean and tight, and wiring not damaged, repair/replace as needed

iv. Check for igniter/sensor cracked ceramic

insulator, replace if needed

VIII. Operation (continued)

v. Check the pilot ame. It must be blue,

steady and envelop the ame sensing rod

3/8” to ½”.

vi. If needed, adjust pilot ame by

turning the gas valve pilot adjustment screw clockwise to decrease or counterclockwise to increase pilot

ame. Always reinstall pilot adjustment

IX. Service and Maintenance

Refractory Ceramic Fiber Product

Important Product Safety Information

Warning:

The Repair Parts list designates parts that contain refractory ceramic fibers (RCF). RCF has been classified as a possible human carcinogen. When exposed to temperatures above 1805°F, such as during direct flame contact, RCF changes into crystalline silica, a known carcinogen. When disturbed as a result of servicing or repair, these substances become airborne and, if inhaled,

may be hazardous to your health.

AVOID Breathing Fiber Particulates and Dust

Precautionary Measures:

Do not remove or replace RCF parts or attempt any service or repair work involving RCF without wearing the following protective gear:

1. A National Institute for Occupational Safety and Health (NIOSH) approved respirator

2. Long sleeved, loose fitting clothing

3. Gloves

4. Eye Protection

• Take steps to assure adequate ventilation.

• Wash all exposed body areas gently with soap and water after contact.

• Wash work clothes separately from other laundry and rinse washing

machine after use to avoid contaminating other clothes.

• Discard used RCF components by sealing in an airtight plastic bag. RCF and crystalline silica are not classified as hazardous wastes in the United

States and Canada.

First Aid Procedures:

• If contact with eyes: Flush with water for at least 15 minutes. Seek

immediate medical attention if irritation persists.

• If contact with skin: Wash affected area gently with soap and water.

Seek immediate medical attention if irritation persists.

• If breathing difficulty develops: Leave the area and move to a location

with clean fresh air. Seek immediate medical attention if breathing difficulties persist.

• Ingestion: Do not induce vomiting. Drink plenty of water. Seek

immediate medical attention.
