WARNING

If you do not follow these instructions exactly,

a fire or explosion may result causing property

damage or personal injury.

DANGER

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.

NOTICE

Due to the low water content of the boiler, mis-

sizing of the boiler with regard to the heating

system load will result in excessive boiler cycling

and accelerated component failure. Burnham

DOES NOT warrant failures caused by mis-sized

boiler applications. DO NOT oversize the boiler to

the system. Modular boiler installations greatly

reduce the likelihood of boiler oversizing.

Installation must conform to the requirements of the

authority having jurisdiction. In the absence of such

requirements, installation must conform to the National

Fuel Gas Code, NFPA 54/ANSI Z223.1, and/or CAN/

CSA B149.1 Installation Codes.

Appliance is design certified for installation on

combustible flooring. Do not install boiler on

carpeting.

Provide clearance between boiler jacket and

combustible material in accordance with local fire

ordinance. Refer to Figure 1 for minimum listed

clearance from combustible material. Recommended

service clearance is 24 inches from left side, right

side and front. Service clearances may be reduced to

minimum clearances to combustible materials.

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. Floor

must be able to support weight of boiler, water and all

additional system components.

Protect gas ignition system components from water

(dripping, spraying, rain, etc.) during boiler operation

and service (circulator replacement, condensate trap,

control replacement, etc.).

I. Pre-Installation

Provide combustion and ventilation air in accordance

with applicable provisions of local building codes,

or: USA - National Fuel Gas Code, NFPA 54/ANSI

Z223.1, Air for Combustion and Ventilation;

Canada - Natural Gas or Propane Installation Code,

CAN/CSA-B149.1.

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.

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. 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 sill 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.
