Installing the water heater:
Properoperation 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(Indoor Water Heater Only)
NOTICE: If the waterheater is installed in
an unconfined space within a building of
conventional frame, masonry ormetal
construction, infiltration airis normally
adequate forproper combustion and
ventilation. If the waterheater is installed in
a confined space, provisions forcombustion
and ventilation airmust be made.
Aconfined space is one having a volume
of less than 50 cubic feet (1.4 cubic
meters) per 1000 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” (30 cm) above
the floor and the other is to be located
within 12” (30 cm) below the ceiling.
The minimum net free area of each opening
must not be less than one square inch (6.5
sq cm) per 1000 Btuh of the total input
rating of all the appliances in the
enclosure (but not less than 100 square
inches (650 cm2),) if each opening
communicates with other unconfined 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 two
openings located as specified above and
each must have a minimum net free area
of not less than one square inch
(6.5 sq cm) per 4000 Btuh of the total
input rating of all the appliances in the
enclosure.
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
(6.5 sq cm) per 2000 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 3” (7.6 cm).
NOTICE: If the duct openings which supply
combustion and ventilation airare to be
covered with a protective screen orgrill, the
net free area (openings in the material) of
the covering material must be used in
determining the size of the openings.
Protective screening forthe openings MUST
NOTbe smaller than 1/4” (0.64 cm) mesh to
prevent clogging by lint orother 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 flame
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 flame.
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 airsupply containing
halogenated hydrocarbons.
Inspect Shipment
Inspect the water heater for possible damage. Check the markings on the rating plate of
the water heater to be certain the type of gas supplied corresponds to the water heater
requirements. Verify all included parts are present (see below).
