Combustion Air Supply and 
Ventilation
IMPORTANT:  Air for combustion and ventilation must not 
come from a corrosive atmosphere. Any failure due to 
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
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 or air inlet.
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.
Carbon Monoxide Warning
Follow all the local and state codes or, in 
the absence of local and state codes, the 
“National Fuel Gas Code”, ANSI Z223.1 
(NFPA 54)- latest edition to properly install 
vent system.
Failure to do so can result in death, 
explosion, or carbon monoxide poisoning.
