Safety Instructions Installation Instructions Operating Instructions Care and Cleaning Troubleshooting Tips Customer Service

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.

DANGER!

LIQUIFIED PETROLEUM (LP—PROPANE OR BUTANE)
AND NATURAL GAS MODELS

!

● Water heaters utilizing LP gas are different

from natural gas models. A natural gas
water heater will not function safely on LP
gas and vice versa.

● No attempt should ever be made to

convert the water heater from natural gas
to LP gas. To avoid possible equipment
damage, personal injury or fire, do not
connect the water heater to a fuel type
not in accordance with the unit data plate.
LP for LP units. Natural gas for natural
gas units. These units are not certified for
any other fuel type.

● LP appliances should not be installed below

grade (for example, in a basement) if such
installation is prohibited by federal, state
and/or local laws, rules, regulations or
customs.

● 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 a gas
leak, be sure to sniff near the floor also.

● Gas detectors are recommended in LP

& natural gas applications and their
installation should be in accordance
with the detector 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, etc., be used to detect leaks
in gas applications.

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.

SAFETY PRECAUTIONS

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, 400 P Street, 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.

READ AND FOLLOW THIS SAFETY INFORMATION
CAREFULLY.

SAVE THESE INSTRUCTIONS

!

Installing the water heater.

This water heater must be installed in accordance with these instructions, local codes, utility
company requirements, and/or in the absence of local codes, use the latest edition of the
American National Standard/National Fuel Gas Code. A copy can be purchased from either
the American Gas Association, 400 N. Capitol Street NW, Washington, DC 20001 as ANSI
standard Z223.1 or National Fire Protection Association, 1 Batterymarch Park, Quincy, MA
02269 as booklet NFPA 54.

Location

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.

The water heater must be located so it is
not subject to physical damage, for example,
by moving vehicles, area flooding, etc.

If local codes require the use of a stand
kit to raise the water heater 18” above the
floor, please contact the store where the
water heater was purchased, or any water
heater distributor. These kits must
comply with local codes.

● The water heater should be installed as

close as practical to the gas vent or
chimney.

● 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.

● Do not install the water heater in

bathrooms, bedrooms, any occupied
rooms normally kept closed, or in
unprotected outdoor areas.

● 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.

● If the water heater is installed in an

alcove or closet, the entire floor must
be covered by a wood or metal panel.
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.

The auxiliary catch pan
installation MUST conform
to local codes.

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.

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.

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.

A confined space is one having a volume of
less than 50 cubic feet per 1000 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” from the ceiling.

The minimum net free area of each opening
must not be less than one square inch per
1000 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.

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
4000 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
2000 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 3”.

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 then 1/4” mesh 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.

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 air supply
containing halogenated
hydrocarbons.

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.

Safety Instructions Installation Instructions Operating Instructions Care and Cleaning Troubleshooting Tips Customer Service

Thermal Expansion

Determine if a check valve exists in the inlet water line. Check with your local water
utility. It may have been installed in the cold water line as a separate back flow preventer, or it

may be part of a pressure reducing valve, water meter or water softener. A check valve located in
the cold water inlet line can cause what is referred to as a “closed water system”. A cold
water inlet line with no check valve or back flow prevention device is referred to as an “open”
water system.

As water is heated, it expands in volume and creates an increase in the pressure within the water
system. This action is referred to as “thermal expansion”. In an “open” water system,
expanding water which exceeds the capacity of the water heater flows back into the city main
where the pressure is easily dissipated.

A “closed water system”, however, prevents the expanding water from flowing back into the
main supply line, and the result of “thermal expansion” can create a rapid and dangerous
pressure increase in the water heater and system piping. This rapid pressure increase can quickly
reach the safety setting of the relief valve, causing it to operate during each heating cycle.
Thermal expansion, and the resulting rapid, and repeated expansion and contraction of
components in the water heater and piping system can cause premature failure of the relief
valve, and possibly the heater itself. Replacing the relief valve will not correct the problem!

The suggested method of controlling thermal expansion is to install an expansion tank in the cold
water line between the water heater and the check valve (see illustration below). The expansion
tank is designed with an air cushion built in that compresses as the system pressure increases,
thereby relieving the over pressure condition and eliminating the repeated operation of the relief
valve. Other methods of controlling thermal expansion are also available. Contact your installing
contractor, water supplier or plumbing inspector for additional information regarding this subject.

Combustion Air
Inlet Openings

Water Supply Connections

Refer to the illustration below for suggested typical installation. The installation of unions or
flexible copper connectors is recommended on the hot and cold water connections so that the
water heater may be easily disconnected for servicing if necessary. The HOT and COLD water
connections are clearly marked and are 3/4” NPT on all models. Install a shut-off valve in the cold
water line near the water heater.

IMPORTANT: Do not apply
heat to the HOT or COLD
water connections. If sweat
connections are used,
sweat tubing to adapter
before fitting adapter to
the cold water connections
on heater. Any heat applied
to the cold water supply
fittings will permanently
damage the dip tube.
