Installing the water heater
The installation of this water heater must be in accordance with the Manufactured Home
Construction and Safety Standard (Title 24, CFR; Part 3280) and the following instructions;
supplied with the roof jack assembly, local codes, and utility company requirements governing the
installation of water heaters in manufactured homes (mobile homes) and/or in the absence of local
codes, the latest edition of The National Fuel Gas Code, ANSI Z223.1.
Location
This water heater must be installed
within an enclosure so as to separate the
water heater’s combustion and venting
system from the interior atmosphere of
the manufactured home.
All air for combustion must be obtained
from the outside atmosphere, and the
products of combustion (flue gases) must
be discharged directly to the outside
atmosphere through the gas vent roof
jack assembly.
Refer to installation illustration as shown
on the next page of this manual.
The water heater should not be located in
an area where leakage from the tank or
connections will result in damage to the
area adjacent to the heater.
When such areas cannot be avoided it is
recommended that a suitable catch pan,
adequately drained, must be installed
under the water heater.
Catch pan kits are available from the store
where the water heater was purchased, or
any water heater distributor. Follow the
instructions provided with the catch pan
kit for proper installation.
Make certain that the floor underneath
the water heater is strong enough to
support the weight of the water heater
once it is filled with water.
A gas fired water heater or any other
appliance should not be installed in
a space where liquids which give off
flammable vapors are to be used or
stored. Such liquids include gasoline,
LP gas (butane or propane), paint or
adhesives and their thinners, solvents or
removers.
● Long hot water lines should be insulated
to conserve water and energy.
● The water heater and water lines
should be protected from exposure to
freezing temperatures.
● Minimum clearance from combustible
construction:
If the clearances stated on the
Instruction/Warning Label, located on
the front of the heater differ, install the
water heater according to the clearances
stated on the label.
The water heater may be installed on
combustible flooring, but not directly on
carpeting.
If the water heater must be installed on
carpeting, place a wood or metal panel
beneath the water heater extending
beyond its full width and depth at least
3” in all directions. If the water heater is
installed in an alcove or closet, the entire
floor must be covered by the panel.
CAUTION: Provisions should be
made so that in the event the water
heater or one of its fittings were to
leak, the resulting flow of water
will not cause damage to the
manufactured home.
CAUTION: DO NOT subject the
water heater to any water
distribution system air pressure
test. The water heater should either
be isolated with valves at the inlet
and outlet water connections or
disconnected during the test.
Failure to properly isolate the
water heater during an air
pressure test presents a hazard to
life and property. With a water
pressure test the water heater need
not be isolated.

WARNING:
Combustible
construction refers
to adjacent walls
and ceilings and
should not be
confused with
combustible or
flammable products
and materials.
Combustible and/or
flammable products
and materials
should never be
stored in the vicinity
of this or any gas
appliance.
