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
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: This water heater should not be located
in an area where 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 damaged 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.
• I f 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 page 34.
