Installation

Codes

Installations must comply with all local codes, laws, regulations and ordinances. Also National Fuel Gas Code ANSI Z223.1-latest edition. When required, installations must conform to Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1. Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on boiler when boiler underwent tests specified in ANSI Z21.13-latest edition.

Canadian installations must comply with CAN/CSA B149.1 or .2 Installation Codes. The equipment shall be installed in accordance with those installation regulations in force in the local area where the installation is to be made. These shall be carefully followed in all cases. Authorities having jurisdiction shall be consulted before installations are made.

Combustion air and ventilation openings

Combustion air and ventilation openings must comply with Section 5.3, Air for Combustion and Ventilation, of National Fuel Gas Code ANSI-Z223.1-latest edition, or applicable building codes. Canadian installations must comply with CAN/CSA B149.1 or .2 Installation Codes.

Provide adequate combustion and ventilation air to:

•Assure proper combustion

•Reduce risk or severe personal injury or death from flue gas spillage and carbon monoxide emissions.

Do not install an exhaust fan in the boiler room.

Boiler installation must assure sufficient openings in building and boiler room to provide adequate combustion air and ventilation. Consider construction tightness of building when deciding whether additional outside openings may be needed.

Older buildings with single-pane windows, minimal weatherstripping and no vapor barrier often provide enough natural infiltration and ventilation without dedicated openings.

New construction or remodeled buildings are most often built tighter. Windows and doors are weatherstripped, vapor barriers are used and openings in walls are caulked. As a result, such tight construction is unlikely to allow proper natural air infiltration and ventilation.

Air from inside building (boiler in interior room):

•Tightly constructed buildings must be provided with openings to outside for combustion and ventilation air. These openings must be sized to handle all fuel burning appliances, exhaust and ventilation fans and fireplaces.

•When openings to boiler room are taken to interior spaces, provide two permanent openings: a combustion air opening within 12 inches of floor and a ventilation opening within 12 inches of ceiling. Each opening must provide a minimum free area of one square inch per 1,000 Btuh input of all appliances in room plus requirements for any exhaust fans in room. The interior space supplying combustion and ventilation air must have adequate infiltration from outside.

Air directly from outside to boiler room:

•Tightly constructed buildings must be provided with combustion air and ventilation openings to boiler room which are adequate to handle the boiler needs plus the needs of all other fuel-burning appliances, fireplaces and exhaust or ventilation fans.

•Combustion and ventilation openings connecting directly or by ducting to outside, or to attic or crawl spaces that freely connect with outside, must be sized as follows:

1.Outside wall or vertical ducting - one square inch per 4,000 Btuh input of all appliances in room plus requirements for any exhaust fans or other appliances in room.

2.Horizontal ducting - one square inch per 2,000 Btuh of all appliances in room plus requirements for any exhaust fans or other appliances in room.

3.All ducting must be same size as permanent openings. Minimum area dimensions of ducting must be no less than 9 square inches.

4.Other size ducting must comply with local codes.
