Burnham PVG manual Pre-Installation

WARNING

If you do not follow these instructions exactly, a fire or explosion may result causing property damage or personal injury.

F.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.

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.

A. 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.

B.Appliance is design certified for installation on combustible flooring. Do not install boiler on carpeting.

C.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.

D.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.

E.Protect gas ignition system components from water (dripping, spraying, rain, etc.) during boiler operation and service (circulator replacement, condensate trap, control replacement, etc.).

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.

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
