Installing the SHLX
COMBUSTION AND VENTILATION AIR
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.
Air Openings
Min. 200
Sq. In.
Min. 4"
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 per 4,000 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 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".
NOTICE: If the water heater is installed in an unconfined space within a building of conventional frame, masonry or
metal construction, infiltration air is normally adequate for proper combustion and ventilation. If the water heater is
installed in a confined 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" 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 flame corrosive elements
are released that will shorten the life of any gas
burning appliance.
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).

A confined 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 floor 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 unconfined areas inside the building.

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 any air supply containing
halogenated hydrocarbons.
