Choosing a Location
WARNING:
Fire Hazard –Combustible construction refers to adjacent
walls and ceilings and should not be confused with
combustible or flammable products and materials.
Combustible materials, such as clothing, cleaning
materials, or flammable liquids, must not be placed against
or next to the water heater. Fire or explosion could occur
causing death, personal injury, and/or product or property
damage.
A gas-fired water heater should never be installed in a
space or room where liquids with flammable vapors are
used or stored. Such liquids include gasoline, LP gas
(butane or propane), paint, adhesives and their thinners,
solvents, or removers. Flammable vapors carry long
distances from where they are used or stored. The open
flame of the water heater’s main burner can ignite these
vapors causing an explosion or fire.
NOTICE:
Elevating a gas-fired water heater will reduce but NOT
eliminate the possibility of lighting the vapor of flammable
liquids which may be improperly stored or accidentally
spilled.
NOTICE:
DO NOT connect power until venting installation is complete
(see Venting installation).
NOTICE:
This water heater should not be located in an area where
water leakage of the heat exchanger or connections will
result in damage to the area adjacent to it or to lower floors
of the structures. When such areas cannot be avoided,
install a suitable catch pan with an adequate drain under
the water heater.
The following requirements will ensure a safe
installation:
• The water heater must be located in an area where
it won’t sustain damage from moving vehicles,
flooding, etc. If the water heater is installed in a
storage garage, the direct ignition system and main
burner should be no less than 18 in. (45 cm) above
the garage floor.
• If the water heater is installed in a repair garage or
in a private garage, the direct ignition system and
main burner should be no less than 4.5 ft (1400
mm) above the garage floor.
• The water heater should be installed as close as
possible to the vent exhaust and air intake. This
minimizes the vent length and the number of
elbows and joints required for venting.
• The water heater should be installed with the
correct venting and exhaust materials. See
"Venting" in this Use and Care Manual.
