DANGER!
LIQUEFIED PETROLEUM MODELS
Both 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.
Installation Instructions
Safety Instructions
IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
● 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.
Operating Instructions
● 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. Propane for propane units. Natural
gas for natural gas units. These units are
not certified for any other fuel type.
Care and Cleaning
● 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.
● Propane or 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.
Troubleshooting Tips
● Make sure to look and smell for LP gas
leaks before attempting to light the
appliance. 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 too.
Customer Service
● Gas detectors are recommended in LP
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 be used to detect leaks in LP gas
applications.
4
If LP gas 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.
● Keep the area clear until the service call
has been made, the leak is corrected and
a qualified agency has determined the
area to be safe.

heater.
Catch pan kits are available in 16″, 19″,
22″, 24″ and 261/2″ from the store where
the water heater was purchased, or any
water heater distributor.
For these reasons, installation of a
gas-fired water heater in a garage is not
recommended.
Stand kits to raise the water heater
18″ above the floor are available from
the store where the water heater was
purchased, or any water heater
distributor. These kits must comply
with local codes. Request “Stand Kit,
Part Number AS-29061.”
● 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
outdoor unprotected areas.
● Minimum clearance from combustible
construction is 0″ sides and rear;
3″ from front of control enclosure;
12″ from the top. 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 floors, but not directly on
carpeting. If the water heater must be

Customer Service
Raising the gas-fired water heater will
reduce, but not eliminate, the possibility
of lighting the vapor of any flammable
liquids which may be improperly stored
or accidentally spilled.
● Long hot water lines should be
insulated to conserve water and energy.
Troubleshooting Tips
WARNING: If a location
in a garage is the only
alternative, the gas water
heater should be installed
so that the spark ignitor
and main burner are no
less than 18″ above
the garage floor, unless
specifically exempted from
this by local code, rule,
regulation or custom.
Because of natural air movement
in a room or other enclosed space,
flammable vapors can be carried some
distance from where their liquids are
being used or stored. The water heater’s
spark ignitor or main burner can ignite
these vapors, causing an explosion or
fire which may result in severe burns,
death or property damage.
● The water heater should be installed
so as to minimize the length of
plastic vent pipe and the number of
vent elbows required. (See “Venting”
later in this section for specific
limitations.)
Care and Cleaning
A gas-fired water heater 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 and propane), paint or
adhesives and their thinners, solvents
or removers.
The water heater must be located so
it is not subject to physical damage,
for example, by moving vehicles, area
flooding, etc.

Installation Instructions
B
The water heater should not be located
in an area where leakage of the tank or
connections will result in damage to the
area adjacent to it or to lower floors of
the structure.
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.
Combustion and Ventilation Air
NOTE: 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″ below 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″.
NOTE: If the duct openings are
to be covered with a protective
screen or grille, the net free area
of the covering material must be
used in determining the size of the
openings. Protective screening for
the openings MUST NOT be smaller
than 1/4″ mesh to prevent clogging
by lint or other debris.
CAUTION: Large exhaust fans
can lower the air pressure inside
a building or room and interfere
with proper venting and operation.
Commercial kitchens or other
locations that must maintain a high
flow of exhaust air should have the
water heater installed in a separate
room with combustion and
ventilation air supplied directly
from outside as described above.
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 contains 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 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.

Safety Instructions
Installing the water heater.
A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves and
Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22, must be installed in the
opening provided and marked for the purpose on the water heater. No valve of any type should be installed
between the relief valve and the tank. Local codes shall govern the installation of relief valves.
Relief Valve
The BTUH rating of the relief valve
must equal or exceed the BTUH input
of the water heater as marked on its
rating plate.
Position the outlet of the relief valve
above a suitable open drain to eliminate
potential water damage. Piping used
should be of a type approved for hot
water distribution.
WARNING: The tank
must be full of water before
heater is turned on. The
water heater warranty does
not cover damage or failure
resulting from operation
with an empty or partially
empty tank.
The discharge line must be no smaller
than the outlet of the valve and must
pitch downward from the valve to allow
complete drainage (by gravity) of the
relief valve and discharge line.
The end of the discharge line should not
be threaded or concealed and should be
protected from freezing. No valve of
any type, restriction or reducer
coupling should be installed in
the discharge line.
To Fill the Water Heater
Make certain that drain valve is closed,
then open the shut-off valve in the cold
water supply line.
Open a nearby hot water faucet(s)
slowly to allow the air to vent from
the water heater and piping.
A steady flow of water from the hot
water faucet(s) indicates a full water
heater.
Condensation
Condensation can form on the tank when
it is first filled with water. Condensation
might also occur with a heavy water
draw and very cold inlet water
temperatures.
Troubleshooting Tips
Care and Cleaning
Operating Instructions
Installation Instructions
The pressure rating of the relief valve
must not exceed 150 PSI, the maximum
working pressure of the water heater
as marked on the rating plate.
Drops of water falling on the burner can
produce a sizzling or pinging sound, and
the water may also be seen beneath the
water heater.
Customer Service
This condition is not unusual, and will
disappear after the water becomes
heated. If, however, the condensation
continues, examine the piping and
fittings for possible leaks.
10
Draining the Condensate
In certain conditions, installations in
unconditioned space or having long
horizontal or vertical runs may
accumulate condensate. In order to
prevent condensate from draining back
into the blower, we recommend a
condensate tee and drain to be installed
in a horizontal vent section as close as
practical to the blower vent connection.
Condensate is known to be acidic; refer
to local, state or federal codes for
proper handling methods.
Gas Supply
Compound used on the threaded joints
of the gas piping must be of the type
resistant to the action of LP gas.
WARNING: Never use an
open flame to test for gas
leaks, as bodily injury,
property damage or death
could result.
A sediment trap should be installed at
the bottom of the gas line.
Do not use excessive force (over 31.5 ft lbs.)
in tightening the pipe joint at the gas valve
inlet, particularly if Teflon pipe compound is
used, as the valve body may be damaged.
The inlet gas pressure to the water
heater must not exceed 14″ W.C. for
Natural or LP gas. For purposes of input
adjustment, the minimum inlet gas
pressure (with main burner on) is shown
on the water heater rating plate. If high
or low gas pressures are present,
contact your gas supplier for correction.
Leak Testing
The factory connections to the gas valve
and fittings should also be leak tested
after the water heater is placed in
operation.
Turn on the manual gas shut-off
valve near the water heater.
Use a soapy water solution to test
for leaks at all connections and
fittings. Bubbles indicate a gas leak
that must be corrected.
The water heater and its manual gas
shut-off valve must be disconnected
from the gas supply piping system
during any high pressure testing of
that system at pressures in excess
of 1/2 PSIG (14″ W.C.).
The water heater must be isolated from
the gas piping system by closing the
manual gas shut-off valve. The valve only
needs to be closed during testing at
pressures equal to or less than 1/2 PSIG
(14″ W.C.).
Troubleshooting Tips
Pressure Testing the Gas Supply System
Care and Cleaning
The water heater and its gas
connections must be leak tested at
normal operating pressures before
it is placed in operation.
Operating Instructions
A ground joint union or ANSI design
certified semi-rigid or flexible gas
appliance connector should be installed in
the gas line close to the water heater,
and a manual gas shut-off valve should
be installed in the gas line prior to the
union. A manual gas shut-off valve should
be at least 5 ft. above the floor and
readily accessible, for turning on or off.
Use compound sparingly on male
threads only.
Installation Instructions
The branch gas supply line to the water
heater should be clean 1/2″ black steel
pipe or other approved gas piping
material.
Safety Instructions
WARNING: Do not attempt to convert this water heater for use with a different type of gas other than the type
shown on the rating plate. Such conversion could result in hazardous operating conditions.

insert 1⁄2″ mesh metal screen into terminal elbow and join it
to the short piece of vent pipe.
JOINING PIPES AND FITTINGS—All pipe, fittings,
solvent cement, primers and procedures must conform to
American National Standards Institute and American
Society for Testing and Materials (ANSI/ASTM) standards.
CEMENTING JOINTS—All joints in the vent piping
must be properly sealed and we recommend using the
following material: PVC materials should use ASTM D-2564
grade cement; CPVC materials should use ASTM F-493
grade cement; ABS materials should use ASTM D-2235
grade cement.
All joints in the vent piping must be properly sealed using
the following material and procedure:
Cleaner-Primer and Medium Body Solvent
Cement
Cut pipe end square, remove jagged edges and burrs.
Chamfer end of pipe, then clean fitting socket and pipe
joint area of all dirt, grease or moisture.
After checking pipe and socket for proper fit, wipe
socket and pipe with cleaner-primer. Apply a liberal
coat of primer to inside surface of socket and outside
of pipe. Do not allow primer to dry before applying
cement.
Apply a thin coat of cement evenly in the socket.
Quickly apply a heavy coat of cement to the pipe end
and insert pipe into fitting with a slight twisting
motion until it bottoms out.
14 NOTE: Cement must be fluid; if not, recoat.
Hold the pipe fitting for 30 seconds to prevent the
tapered socket from pushing the pipe out of the fitting.
Wipe all excess cement from the joint with a rag.
Allow 15 minutes before handling. Cure time will vary
according to fit, temperature and humidity.
NOTE: Stir the solvent cement frequently while
using. Use a natural bristle brush or the dauber
supplied with the can. The proper brush size is 1″.
CAUTION: FOR PROPER INSTALLATION:
• DO NOT use solvent cement that has become
curdled, lumpy or thickened.
• DO NOT thin solvent cement. Observe shelf
precautions printed on the containers.
• For applications below 32°F use only low
temperature-type solvent cement.
• Appropriate solvent and cleaner must be used
for the type of vent pipe used (PVC, CPVC or
ABS).
WARNING: DANGER OF FIRE OR BODILY
INJURY – Solvent cements and primers are highly
flammable. Provide adequate ventilation and do not
assemble near heat source or open flame. Do not
smoke. Avoid skin or eye contact. Observe all
cautions and warnings on material containers.

to make certain the valve operates freely.
Allow several gallons to flush through the
discharge line to an open drain. Make certain
the discharged water is directed to a suitable
drain.
NOTE: If the temperature and pressure
relief valve on the hot water heater
discharges periodically, this may be due
to thermal expansion in a closed water
system. Contact the water supplier or
your plumbing contractor on how to
correct this. Do not plug the relief valve
outlet.
A water heater’s tank can act as a settling
basin for solids suspended in the water.
It is therefore not uncommon for hard water
deposits to accumulate in the bottom of the
tank. Deposits should not be allowed to
accumulate, as this can affect the service life of
the water heater. It is suggested that a few
quarts of water be drained from the water
heater’s tank every month to clean the tank of
these deposits. If sufficient hard water
deposits accumulate, a rumbling or pounding
sound can occur. There is no danger involved
and the efficiency of the water heater is not
seriously affected, but the noise can be
annoying. Your plumbing contractor should be
contacted to clean the tank of these deposits.
Rapid closing of faucets or solenoid valves in
automatic water-using appliances can cause a
banging noise heard in a water pipe.
Strategically located risers in the water pipe
system or water hammer arresting devices can
be used to minimize the problem.
Customer Service
Housekeeping
Vacuum around the base of the water heater for
dust, dirt and lint on a regular basis.
Inspect the blower for excessive lint buildup and
clean as necessary.

To ensure sufficient ventilation and combustion
air supply, proper clearances must be
maintained.
DANGER: Combustible materials,
such as clothing, cleaning materials or
flammable liquids, must not be placed
against or next to the water heater.
When reinstalling the flue baffle make
certain it is hung securely by its
hanger at the top of the flueway.
Remove any scale that may have
fallen on the burner or floor shield
and reinstall the draft hood (with
four screws) to the blower support
bracket and water heater’s top pan.
Inspect the plastic vent pipe. Make
certain that all joints are secure and
that vent pipe supports are in place.
Check outdoor vent terminal to see
that it is free of obstructions, and
that there is no damage nearby
caused by condensate.
If, after inspection of the vent
system, you found sooting or
deterioration, call the local gas utility
to correct the problem and clean or
replace the flue and venting before
resuming operation of the water
heater.
Visually inspect the burners annually
while firing.
Proper burner and pilot flame
pattern.
For cleaning, remove the burner from
the water heater. A vacuum cleaner
can be used on the burner and floor
Vacation and Extended Shut-Down
If the water heater is to remain idle
for an extended period of time, the
gas and power should be turned off
to conserve energy.
The Anode
Rod is
completely
covered by the
Blower
Assembly.
Anode Rod
This water heater is equipped with an
anode rod designed to prolong the
life of the glass-lined tank. The anode
rod is slowly consumed cathodically,
thereby eliminating or minimizing
corrosion of the glass-lined tank.
Water sometimes contains a high
sulfate and/or mineral content and
together with cathodic protection
process can produce a hydrogen
sulfide, or rotten egg odor in the
heated water. Chlorination of the
water supply should minimize the
problem.
The anode rod should be removed
from the water heater’s tank annually
for inspection and replaced when
more than 6″ of core wire is exposed
at either end of the rod.
Make sure the cold water supply is
turned off before removing anode rod.
21
Customer Service
NOTE: Do not remove the anode
rod from the water heater’s tank,
except for inspection and/or
replacement, as permanent
removal will shorten the life of
the glass-lined tank and affect
the water heater warranty.
After a long shut-down period, the
water heater’s operation and controls
should be checked by qualified service
personnel. Make certain the water
heater is completely filled again
before placing it in operation.
Troubleshooting Tips
The water heater and piping should be
drained if they might be subjected to
freezing temperatures.
