LIQUEFIED PETROLEUM (LP - PROPANE OR BUTANE)
AND NATURAL GAS MODELS
LP and Natural gas have an odorant added to aid in detecting a gas leak. Some people
may not physically be able to smell or recognize this odorant. If you are unsure or
unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions,
such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or
camouflage a gas leak.
● This water heater is supplied with a
thermostatic gas valve that is convertible
to LP from natural gas. Be sure to read
and carefully follow the Conversion
Instructions included in this manual
when converting the valve from one
type of gas to another.
● After conversion, be certain that the gas
supplied to the heater is the type that
the valve has been converted for (LP for
heaters converted to LP use, and natural
gas for heaters converted to natural gas
use). This water heater will not operate
safely if connected to a fuel type other
than the one the gas valve is converted
for.
● LP gas must be used with great caution.
It is heavier than air and will collect first
in lower areas making it hard to detect at
nose level.
● Before attempting to light the water
heater, make sure to look and smell for
gas leaks. Use a soapy solution to check
all gas fittings and connections. Bubbling
at a connection indicates a leak that must
be corrected. When smelling to detect an
LP leak, be sure to sniff near the floor
also.
DANGER: If a gas leak is present or
suspected:
● Do not attempt to find the cause yourself.
● Do not try to light any appliance.
● Do not touch any electrical switch.
● Do not use any phone in your building.
● Leave the house immediately and make
sure your family and pets leave also.
● Leave the doors open for ventilation
and contact the gas supplier, a qualified
service agency or the fire department.
● Stay away from the house (or building)
until the service call has been made, the
leak is corrected and a qualified agency
has determined the area to be safe.
● Gas detectors are recommended in LP
and natural gas applications and their
installation should be in accordance with
the manufacturer’s recommendations
and/or local laws, rules, regulations or
customs.
● It is recommended that more than one
method, such as soapy solution, gas
detectors, be used to detect leaks in LP
gas applications.

IMPORTANT SAFETY INFORMATION.
!
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
For your safety, the information in this manual must be followed to minimize the risk of
fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of
life.
FOR INSTALLATIONS IN THE STATE OF CALIFORNIA
California Law requires that residential water heaters must be braced, anchored or
strapped to resist falling or horizontal displacement due to earthquake motions. For
residential water heaters up to 52-gallon capacity, a brochure with generic earthquake
bracing instructions can be obtained from: Office of the State Architect, 1102 Q Street,
Suite 5100, Sacramento, CA 95814 or you may call 916-445-8100 or ask a water heater
dealer.
However, applicable local codes shall govern installation. For residential water heaters
of a capacity greater than 52 gallons, consult the local building jurisdiction for acceptable
bracing procedures.
SAFETY PRECAUTIONS
Have the installer show you the location of the gas shut-off valve and how to shut it off
if necessary. Turn off the manual shut-off valve if the water heater has been subjected to
overheating, fire, flood, physical damage or if the gas supply fails to shut off.
● Read this manual entirely before installing
or operating the water heater.
● Use this appliance only for its intended
purpose as described in this Use and Care
Manual.
● Be sure your appliance is properly installed
in accordance with local codes and the
provided installation instructions.
● Do not attempt to repair or replace any part
of your water heater unless it is specifically
recommended in this manual. All other
servicing should be referred to a qualified
technician.

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.
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.
Sides
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. There must
not be any door or other opening into the
water heater enclosure from the inside of the
manufactured home.
Refer to installation methods A as shown
on page 9 of this manual. The water heater
enclosure access panel (door) must be in the
outside wall of the manufactured home. Any
opening for piping must be sealed. Minimum
ceiling height within enclosure is 6'6".
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 or to lower floors of
the structure.
When such areas cannot be avoided it is
recommended that a suitable catch pan,
adequately drained, must be installed under
the water heater.
The pan must not restrict air flow to the
combustion air inlet openings (perforation
openings) located around the lower perimeter
of the water heater.
Catch pan kits are available from the store
where the water heater was purchased, or
any water heater distributor.
Make certain the floor underneath the water
heater is strong enough to
sufficiently 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.
When installed in a closet, DO NOT block
or obstruct any of the combustion air inlet
openings located around the perimeter
of the water heater. A minimum of 1” is
required between these combustion air
inlet openings and any obstruction.
Because of natural air movement in a room
or other enclosed space, flammable vapors
can be carried some distance from where
liquids which give off flammable vapors
are to be used or stored. The open flame of
the water heater’s pilot or main burner can
ignite these vapors and create a shut down
condition of the water heater which will
not allow the water heater to ignite until
examined by a Qualified Service Technician.
● 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

A minimum of 24” clearance from the
front and top should be available for
adequate inspection and servicing.
● The water heater may be installed on
combustible floors, but not directly on
carpeting. If the water heater must be
installed on carpeting, place a metal or
wood panel beneath the water heater,
extending beyond its full width and depth
at least 3” in all directions.
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.
