Combustion Air Requirements | State Industries GS6, GSX, GPX

BASIC INSTALLATION & OPERATION

Combustion Air Requirements:

WARNING

Carbon Monoxide Warning

Water heater must be vented to outdoors.

Vent must be installed by a qualified technician using the local and state codes or, in the absence of local and state codes, the National Fuel Gas Code,

ANSI Z223.1 (NFPA 54) - current edition, and/or the installation instructions.

Examples of a qualified technican include: gas technicians, authorized gas company personel, and authorized service persons.

Failure to so do can result in death or carbon monoxide poisoning.

IMPORTANT: Air for combustion and ventilation must not come from a ﬂammable or corrosive atmosphere. Any failure due to ﬂammable or corrosive elements in the atmosphere is excluded from warranty coverage.

The following types of installation (not limited to the following) will require outdoor air for combustion due to chemical exposure and may reduce but not eliminate the presence of corrosive chemicals in the air:

•beauty shops

•photo processing labs

•buildings with indoor pools

•water heaters installed in laundry, hobby, or craft rooms

•water heaters installed near chemical storage areas

•water softeners

Combustion air must be free of acid-forming chemicals such as sulfur, ﬂuorine, and chlorine. These elements are found in aerosol sprays, detergents, bleaches, cleaning solvents, air fresheners, paint, and varnish removers, refrigerants, and many other commercial and household products. When burned, vapors from these products form highly corrosive acid compounds. These products should not be stored or used near the water heater, air inlet, or air intake path.

Combustion and ventilation air requirements are determined by the location of the water heater. The water heater may be located in either an open (unconﬁned) area or in a conﬁned area or small enclosure such as a closet or small room. Conﬁned spaces are areas with less than 50 cubic feet for each 1,000 BTUH of the total input for all gas-using appliances.

Unconﬁned Space: A water heater in an unconﬁned space uses indoor air for combustion and requires at least 50 cubic feet for each 1,000 BTUH of the total input for all gas appliances. The table below shows a few examples of the minimum square footage (area) required for various BTUH inputs.

105,000	657	20 x 33
120,000	750	25 x 30
135,000	844	28 x 30

IMPORTANT:

•The area must be open and be able to provide the proper air requirements to the water heater. Areas that are being used for storage or contain large objects may not be suitable for water heater installation.

•Water heaters installed in open spaces in buildings with unusually tight construction may still require outdoor air to function properly. In this situation, outside air openings should be sized the same as for a confined space.

•Modern home construction usually requires supplying outside air into the water heater area.

•Room exhaust fans may effect air requirements.

Conﬁned Space: For the correct and proper operation of this water heater, ample air must be supplied for the combustion, ventilation, and dilution of ﬂue gases. Small enclosures and conﬁned areas must have two permanent openings so that sufﬁcient fresh air can be drawn from outside of the enclosure. One opening shall be within 12 inches of the top and one within 12 inches of the bottom of the enclosure.

The size of each opening (free area) is determined by the total BTUH input of all gas utilization equipment (i.e., water heaters, furnaces, clothes dryers, etc.) and the method by which the air is provided. The BTUH input can be found on the water heater rating plate. Additional air can be provided by two methods:

1.All air from inside the building.

2.All air from outdoors.
