Proper operation of the water heater requires air for combustion and ventilation. Provisions
for combustion and ventilation air must comply with referenced codes and standards.
Combustion and Ventilation Air
Installing the 20HI Water Heater continued....
A conned space is one having a volume of less than 50 cubic feet per
1,000 BTUH of the aggregate input of all appliances within that space.
The air must be supplied through two permanent openings of equal area. One is
to be located within 12” above the oor and the other is to be located within 12”
below the ceiling.
The minimum net free area of each opening must not be less than one
square inch per 1,000 BTUH of the total input rating of all the appliances in the
enclosure (but not less than 100 square inches), if each opening communicates
with other unconned areas inside the building.
Buildings of unusually tight construction shall have the combustion and
ventilation air supplied from outdoors, or a freely ventilated attic or crawl space.
If air is supplied from outdoors, directly or through vertical ducts, there must be
Inspect Shipment
Inspect the water heater for possible damage. Check the markings on the rating plate of the
waterheater to be certain the type of gas supplied corresponds to the water heater requirements.
Verify all included parts are present (see below). Please note that orders shipping to a Canadian
address will include the pressure relief valve.
NOTICE: If the water heater is installed in an unconned space within a building of
conventional frame, masonry or metal construction, inltration air is normally adequate
for proper combustion and ventilation. If the water heater is installed in a conned space,
provisions for combustion and ventilation air must be made.
NOTICE: If the duct openings which supply combustion and ventilation air are to be covered
with a protective screen or grill, the net free area (openings in the material) of the covering
material must be used in determining the size of the openings. Protective screening for the
openings MUST NOT be smaller than 1/4” mesh to prevent clogging by lint or other debris.
Corrosive Atmospheres
The air in beauty shops, dry cleaning
establishments, photo processing labs, and
storage areas for liquid and powdered
bleaches or swimming pool chemicals often
contain such halogenated hydrocarbons.
An air supply containing halogenated
hydrocarbons may be safe to breathe, but
when it passes through a gas ame corrosive
elements are released that will shorten the life
of any gas burning appliance.
Propellants from common spray cans or gas
leaks from A/ C and refrigeration equipment are
highly corrosive after passing through a ame.
The water heater warranty is voided when failure
of the heater is due to operation in a corrosive
atmosphere.
NOTICE: The water heater should not be
installed near an any air supply containing
halogenated hydrocarbons.

two openings located as specied above and each must have a minimum net free area of not less than one

If horizontal ducts are used to communicate with the outdoors, each opening must have a minimum net
free area of not less than one square inch per 2,000 BTUH of the total input rating of all the appliances in the
enclosure. If ducts are used, the minimum dimensions of rectangular air ducts shall not be less than 4”.
