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 filed 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, NFPA 54/ANSI Z223.1, and/or CAN/ CGA B149 Installation Codes. 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 certified for installation on

combustible flooring. The boiler must not be installed on carpeting.

D. Provide clearance between boiler jacket and

combustible material in accordance with local fire ordinance. See Figure 2 for minimum clearance from combustible material for closet installation. For alcove installation provide top clearance of 27 inches and right side clearance of 6 inches. Recommended service clearance is 24 inches from left side, right side and front. Service clearances may be reduced to minimum clearances to combustible materials.

E. Install on level floor. For basement installation provide

solid base, such as concrete, if floor is not level or if water may be encountered on floor around boiler.

F. Install near outside wall for through wall venting. Refer

to Section V: Venting, for vent length limitations.

WARNING

Certified as Category III appliance. Install

vent system in accordance with Section

V: Venting. Do not vent using masonry chimney, Type B gas vent, or other Category I venting system.

G. Protect gas ignition system components from water

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

H. Provide combustion and ventilation air in accordance

with applicable provisions of local building codes, or National Fuel Gas Code, NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation, or Sections 7.2, 7.3 or 7.4 of CAN/CGA B149 Installation 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, NFPA 54/ANSI Z223.1.

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

Figure 2: Minimum Clearances to Combustible

Construction for Closet Installation

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 unconfined space.

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

considered a confined space.

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

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.

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 floors, between wall-ceiling joints, between wall panels, at plumbing and electrical penetrations, and at other openings.

5. For boiler located in an unconfined space in a building of other than unusually tight construction, adequate combustion and ventilation air is normally provided by fresh air infiltration through cracks around windows and doors.

6. For boiler located within unconfined space in

building of unusually tight construction or within confined 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:

Alternate method for boiler located within confined space. Use indoor air if two permanent openings

communicate directly with additional space(s) of sufficient volume such that combined volume of all spaces meet criteria for unconfined 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 fixed 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 flammable

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 floor.

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 Paragraphs 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

CAUTION

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.

CAUTION

Oxygen contamination of boiler water will cause corrosion of iron and steel boiler components, and can lead to boiler failure. Burnham's standard warranty does not cover problems caused by oxygen contamination of boiler water.

F. Space heating and domestic water heating with Alliance

water heater. Install Alliance water heater as a separate heating zone. Refer to Alliance Installation, Operating and Service Instructions for additional information.

G. If boiler is used in connection with refrigeration systems,

boiler must be installed with chilled medium piped in parallel with the heating boiler using appropriate valves to prevent chilled medium from entering boiler, see Figure 4. Also consult I=B=R Installation and Piping Guides.

H. 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 flow control valves to prevent gravity circulation of boiler water during operation of cooling system.

I. 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.).

Oxygen contamination sources are system leaks requiring addition of makeup water, fittings, and oxygen permeable materials in distribution system. Eliminate oxygen contamination by repairing system leaks, repairing fittings, and using nonpermeable materials in distribution system.

B. Connect system supply and return piping to boiler. See

Figure 3. Also consult I=B=R Installation and Piping Guides. Maintain minimum ½ inch clearance from hot water piping to combustible materials.

C. Install Circulator with flanges, gaskets and bolts

provided. Five foot circulator harness allows circulator to be mounted on supply or return. Connect harness to

circulator and secure any excess conduit.

D. Install Safety Relief Valve. See Figure 3. Safety Relief

Valve must be installed with spindle in vertical position. Installation of the relief valve must be consistant with the ANSI/ASME Boiler and Pressure Vessel Code, Section IV.

WARNING

Safety relief valve discharge piping must be piped near floor to eliminate potential of severe burns. Do not pipe in any area

where freezing could occur. Do not install

any shut-off valves.

Install pipe tee between circulator and boiler return along with second tee in supply piping as shown in Figure 3. Bypass should be same size as the supply and return lines with valves located in bypass and supply outlet as illustrated in Figure 3 in order to regulate water flow to maintain higher boiler water temperatures.

After the boiler is operational (reference Section VII. System Start-Up) 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 the by-pass valve will lower system supply temperature.

J. A hot water boiler installed above radiation level must be

provided with a low water cut-off device as part of installation.

K. Oil, grease, and other foreign materials which

accumulate in new hot water boilers and a new or reworked system should be boiled out, and then thoroughly flushed. A qualified water treatment chemical specialist should be consulted for recommendations regarding appropriate chemical compounds and concentrations which are compatible with local environmental regulations.

L. After the boiler and system have been cleaned and

flushed, and before refilling the entire system add

appropriate water treatment chemicals, if necessary, to bring the pH between 7 and 11.

E. Install Drain Valve in ¾" NPT connection in tee

provided. See Figure 1.

Figure 3: Recommended Boiler Piping For Series - Loop Hot Water Heating Systems

Figure 4: Recommended Piping for Combination Heating & Cooling (Refrigeration) 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. Table 1 lists boiler input rate. Also consider existing and expected future gas utilization equipment (i.e. water heater, cooking equipment).

3. Install sediment trap, ground-joint union and manual shut-off valve upstream of boiler gas control valve and outside jacket. 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 and/or CSA C22 Electrical Code.

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 shut-off 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 shut-off valve.

2. Locate leaks using approved combustible gas detector, soap and water, or similar nonflammable solution. Do not use matches, candles, open flames, or other ignition source.

205PV 130 52 ½ 206PV 164 65¾ ½

3. Length of piping and number of fittings. Refer to Table 2 for maximum capacity of Schedule 40 pipe. Table 3 lists equivalent pipe length for standard fittings.

4. Specific gravity of gas. Gas piping systems for gas with a specific gravity of 0.70 or less can be sized directly from Table 2, unless authority having jurisdiction specifies a gravity factor be applied. For specific gravity greater than 0.70, apply gravity factor from Table 4. If exact specific gravity is not shown choose next higher value.

For materials or conditions other than those listed above, refer to National Fuel Gas Code, NFPA 54/ ANSI Z223.1, or size system using standard engineering methods acceptable to authority having jurisdiction.

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, NFPA 54/ANSI Z223.1 and/or CAN/CGA B149 Installation Codes.

2. Use thread (joint) compounds (pipe dope) resistant to action of liquefied petroleum gas.

3. Vent length restrictions are based on equivalent feet of vent pipe (total length of straight pipe in feet plus 5 equivalent feet for each 45° or 90° elbow). Do not exceed the maximum certified vent length of 25 equivalent feet. The minimum certified vent length is 7 equivalent feet. Do not include vent terminal or vent connector in equivalent feet calculations.

4. Do not install venting system components on the exterior of the building except as specifically required by these instructions.

B. Removal of Existing Boiler. For installations not

involving the replacement of an existing boiler, proceed to Step C.

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 remaining appliances. 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 deficiencies which could cause an unsafe condition.

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 (or Operating) Instructions. Adjust thermostat so appliance will operate continuously.

(e) Test for spillage at the drafthood 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.

(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 conditions of use.

(g)Any improper operation of the common venting

system should be corrected so the installation conforms with the National Fuel Gas Code, NFPA 54/ANSI Z223.1. 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 Part II in the National Fuel Gas Code, NFPA 54/ ANSI Z223.1.

C. Install Vent Connector.

1. Remove vent connector from vent accessory carton.

2. Remove gaskets, orifice plate and hardware from blower outlet flange.

3. Assemble orifice plate gaskets, orifice plate, and vent connector. See Figure 7.

4. Secure vent connector with washers and locknuts.

Figure 7: Vent Connector Installation

D. Install Vent Pipe, General.

1. Start at vent connector. Work toward vent terminal.

2. Use ¾ inch pipe strap to support horizontal runs, maintain vent location and slope, and prevent sags. Do not restrict thermal expansion movement. Maximum support spacing is 5 feet.

3. Provide minimum 5 inch clearance to combustible materials. Use thimble when penetrating combustible wall.

a. 203PV and 204PV - Single wall thimble, Burnham

Part No. 8116116. Other wall thimble manufacturers are American Metal Products, Hart & Cooley, and Metal Fab.

b. 205PV and 206PV - Double wall thimble, Burnham

Part No. 8116115 (accomodates 5" to 8¾" wall thickness). Another wall thimble manufacturer is Hart & Cooley.

4. Cut pipe to length using hacksaw with minimum 32 teeth per inch or circular saw with metal abrasive wheel. Remove bead end only - bell end accepts next fitting or pipe. Cut must be square with pipe. Scrape off burrs with sharp edged tool.

Note: If remaining pipe (less bell) must be used, beaded end of mating pipe/fitting must be crimped.

5. Seal all joints using Dow Corning Silastic 732 RTV, Dow Corning Silastic 736 RTV, Polybac #500 RTV, or Sil-bond RTV 4500 (Acetoxy). Do not use other adhesives or sealants.

6. Procedure for joining pipe and fittings. See Figure 8. a. Clean pipe or fitting. Remove all dirt and grease. b. Slip locking band over pipe/fitting bell. c. Apply continuous ¼ inch bead of sealant around

bead end of pipe/fitting no more than 1/8 inch from end.

d. Insert pipe/fitting into bell. Smooth sealant for

continuous seal around gap between bead and bell. Apply additional sealant if necessary.

e. Slip locking band over joint and tighten. Do not

secure joint with sheet metal screws or pop rivets.

E. Horizontal (Through Wall) Vent Installation.

1. Maintain minimum ¼ inch per foot slope in horizontal runs. Slope pipe down toward vent terminal.

CAUTION

2. Vent terminal location restricted per following: a. Minimum 12 inches above grade plus normally

expected snow accumulation level, or 7 feet above grade if located adjacent to public walkway. Do not install over public walkway where local experience indicates condensate or vapor from Category III appliances creates a nuisance or hazard.

Figure 8: Typical Joint Detail

b. Minimum 3 feet above any forced air inlet located

within 10 feet.

c. Minimum 4 foot below, 4 foot horizontally from,

or 1 foot above any door, window, or gravity air inlet.

d. Minimum 4 feet horizontally from, and in no case

above or below, unless a 4-foot horizontal distance is maintained, from electric meters, gas meters, regulators and relief equipment.

e. Minimum 12 inches from overhang or corner.

3. Use wall thimble when passing through combustible outside wall (thimble use optional for noncombustible wall). Insert thimble through wall from outside. Secure outside flange to wall with nails or screws, and seal with adhesive material. Install inside flange to inside wall, secure with nails or screws, and seal with adhesive material.

4. For noncombustible wall when thimble is not used, size opening such that bell with locking band attached cannot pass through.

5. Join vent terminal to vent pipe. Cut vent pipe to locate vent terminal 3 inches (minimum) and 6 inches (recommended) from wall when joined to inside vent piping. See Figure 9. Vent terminal clearance to vinyl wall surfaces is 6 inches.

Moisture and ice may form on surfaces around vent terminal. To prevent deterioration, surfaces should be in good repair (sealed, painted etc.)

6. Insert vent pipe through thimble/opening from outside and join to vent system. Apply sealant between vent pipe and opening/thimble to provide weathertight seal.

Important Product Safety Information

Refractory Ceramic Fiber Product

Warning: This product contains refractory ceramic fibers (RCF). RCF has been classified

as a possible human carcinogen. After this product is fired, RCF may, when exposed to extremely high temperature (>1800F), change into a known human carcinogen. When disturbed as a result of servicing or repair, RCF becomes airborne and, if inhaled, may be hazardous to your health.

AVOID Breathing Fiber Particulates and Dust

Precautionary Measures: Do not remove or replace previously fired RCF (combustion chamber insulation,

target walls, canopy gasket, flue cover gasket, etc.) 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 air tight plastic bag.

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.

VIII. Service

A. General. Inspection and service should be conducted

annually. Turn off electrical power and gas supply while conducting service or maintenance. Follow instructions TO TURN OFF GAS TO APPLIANCE. See Figure 17.

CAUTION
