Combustion Air Supply and
Ventilation
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:

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 BTU/HR of the total input for all
gas-using appliances.

Carbon Monoxide Hazard
Water heater must be vented to outdoors.
Vent must be installed by a qualified person
using the installation instructions.
Examples of a qualified person include:
gas technicians,
authorized gas company personnel,
and authorized service persons.
Failure to follow these instructions can result
in death or carbon monoxide poisoning.
WARNING
