WARNING
Improper installation, adjustment, alteration, service or
maintenance can cause DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE. Refer to this manual for assistance
or consult the local electric utility for further information.
WARNING
At the time of manufacture this water heater was provided with
a combination temperature-pressure relief valve certified by
a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or
materials, as meeting the requirements for Relief Valves and
Automatic Gas Shut-off Devices for Hot Water Supply Systems,
and the current edition of ANSI Z21.22 • CSA 4.4 and the code
requirements of ASME. If replaced, the valve must meet the
requirements of local codes, but not less than a combination
temperature and pressure relief valve certified as meeting the
requirements for Relief Valves and Automatic Gas Shut-off
Devices for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4
by a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or
materials.
The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water
heater (150 lbs. p.s.i.) and a discharge capacity not less than
the water heater input rate as shown on the model rating plate.
(Electric heaters - watts divided by 1000 x 3412 equal BTU/Hr.
rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve complying with ANSI Z21.22
• CSA 4.4 and ASME, may require a valve model different from
the one furnished with the water heater.
Compliance with such local requirements must be satisfied
by the installer or end user of the water heater with a locally
prescribed temperature-pressure relief valve installed in the
designated opening in the water heater in place of the factory
furnished valve.
For safe operation of the water heater, the relief valve must not
be removed from it’s designated opening or plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designated for the relief valve.
Position the valve downward and provide tubing so that any
discharge will exit only within 6 inches above, or at any distance
below the structural floor. Be certain that no contact is made
with any live electrical part. The discharge opening must not be
blocked or reduced in size under any circumstances. Excessive
length, over 30 feet, or use of more than four elbows can cause
restriction and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
drain unless a 6" air gap is provided. To prevent bodily injury,
hazard to life, or property damage, the relief valve must be
allowed to discharge water in quantities should circumstances
demand. If the discharge pipe is not connected to a drain or
other suitable means, the water flow may cause property
damage.
The Discharge Pipe:
• Must not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
• Must not be plugged or blocked.
• Must be of material listed for hot water distribution.
• Must be installed so as to allow complete drainage of both
the temperature-pressure relief valve, and the discharge
pipe.
• Must terminate at an adequate drain.
• Must not have any valve between the relief valve and tank.
WARNING
HAZARD OF ELECTRICAL SHOCK! Before removing any
access panels or servicing the water heater, make sure the
electrical supply to the water heater is turned “OFF”. Failure to
do this could result in DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to
produce hot water. Water heated to a temperature which will
satisfy space heating, clothes washing, dish washing, and
other sanitizing needs can scald and permanently injure you
upon contact. Some people are more likely to be permanently
injured by hot water than others. These include the elderly,
children, the infirm, or physically/mentally handicapped. If
anyone using hot water in your home fits into one of these
groups or if there is a local code or state law requiring a certain
temperature water at the hot water tap, then you must take
special precautions. In addition to using the lowest possible
temperature setting that satisfies your hot water needs, some
type of tempering device, such as a mixing valve, should be
used at the hot water taps used by these people or at the water
heater. Mixing valves are available at plumbing supply or
hardware stores. Follow manufacturers instructions for
installation of the valves. Before changing the factory setting on
the thermostat, read the “Temperature Regulation” section in
this manual.
WARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: This
water heater is equipped for one type voltage only. Check the
rating plate near the bottom access panel for the correct voltage.
DO NOT use this water heater with any voltage other than the
one shown on the model rating plate. Failure to use the correct
voltage can cause problems which can result in DEATH,
SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you
have any questions or doubts consult your electric company.
WARNING
INSULATING JACKETS:When installing an external water
heater insulation jacket on an electric water heater:
a. DO NOT cover the temperature-pressure relief valve.
b. DO NOT put insulation over the access covers or any access
areas.
c. DO NOT remove operating instructions, and safety related
warning labels and materials affixed to the water heater.
d. DO obtain new warning and instruction labels from the
manufacturer for replacement on the blanket directly over
the existing labels.
WARNING
Do not use this appliance if any part of it has been under water.
An electrical short or malfunction could occur. The water heater
should be replaced.
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the water
heater must be accomplished in such a manner that if the tank
or any connections should leak, the flow of water will not cause
damage to the structure. For this reason, it is not advisable to
install the water heater in an attic or upper floor. When such
locations cannot be avoided, a suitable drain pan should be
installed under the water heater. Drain pans are available at
your local hardware store. Such a drain pan must be piped to
an adequate drain.

Facts to Consider About the Location
You should carefully choose an indoor location for the new
water heater, because the placement is a very important
consideration for the safety of the occupants in the building
and for the most economical use of the appliance. This water
heater is not intended for outdoor installation.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
1. The location selected should be indoors as close to and as
centralized with the water piping system as possible. This
water heater, as well as all water heaters, will eventually
leak. Do not install without adequate drainage provisions
where water flow will cause damage.
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the water
heater should be accomplished in such a manner that if the
tank or any connections should leak, the flow of water will not
cause damage to the structure. For this reason , it is not
advisable to install the water heater in an attic or upper floor.
When such locations cannot be avoided, a suitable drain pan
should be installed under the water heater. Drain pans are
available at your local plumbing contractor or hardware store.
Such a drain pan must be piped to an adequate drain.
Water heater life depends upon water quality, water pressure

and the environment in which the water heater is installed.
Water heaters are sometimes installed in locations where
leakage may result in property damage, even with the use of a
drain pan piped to a drain. However, unanticipated damage
can be reduced or prevented by a leak detector or water shut-
off device used in conjunction with a piped drain pan. These
devices are available from some plumbing supply wholesalers
and retailers, and detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or
turn off the incoming water to the water heater when leakage
is detected.
• Sensors mounted in the drain pan that turn off the water
supply to the entire home when water is detected in the
drain pan.
• Water supply shut-off devices that activate based on the
water pressure differential between the cold water and hot
water pipes connected to the water heater.
• Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.
CAUTION
INSTALLATION IN RESIDENTIAL GARAGES: The water heater
must be located and/or protected so it is not subject to physical
damage by a moving vehicle.
2. The location selection must provide adequate clearances
for servicing and proper operation of the water heater.

The water passing out of the drain valve may be extremely hot.
To avoid being scalded, make sure all connections are tight
and that the water flow is directed away from any person.
4. Check again to make sure the electrical supply is turned
“OFF” to the water heater. Then disconnect the electrical
supply connection from the water heater junction box.
5. a. If you have copper piping to the water heater, the two
copper water pipes can be cut with a hacksaw
approximately 4" away from where they connect to the
water heater. This will avoid cutting off the pipes too
short. Additional cuts can be made later if necessary.
Disconnect the temperature-pressure relief valve drain
line. When the water heater is drained, disconnect
the hose from the drain valve. Close the drain valve.
The water heater is now completely disconnected and
ready to be removed.
b. If you have galvanized pipe to the water heater, loosen
the two galvanized pipes with a pipe wrench at the
union in each line. Also disconnect the piping
remaining to the water heater. These pieces should
be saved since they may be needed when
reconnecting the new water heater. Disconnect the
temperature-pressure relief valve drain line. When the
water heater is drained, disconnect the hose from the
drain valve. Close the drain valve. The water heater is
now completely disconnected and ready to be
removed.
CAUTION
Mineral buildup or sediment may have accumulated in the old
water heater. This causes the water heater to be much heavier
than normal and this residue, if spilled out, could cause staining.

8
Section A: Using the Installation Kit
1. Position the water heater so that the existing piping and
electrical hookup will require the shortest distance between
connections. Make sure that you are able to reach the drain
valve and all access panels when the water heater is in
place. This will make it easy to service the water heater. The
water heater must be level before you begin the piping.
If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve, water
meter with a check valve, etc. . . . in the cold water supply;
means shall be provided to control thermal expansion.
Contact the water supplier or plumbing contractor on how to
control this situation.
2. Wrap the 3/4” nipples with teflon tape or pipe joint compound
and screw into the water heater where it’s marked “HOT”
and “COLD”, wrap the other ends of nipples with Teflon tape
or pipe joint compound and screw one end of each flexible
water connector onto each nipple.

carton.
Fit pipe insulation over the incoming cold water line and the hot
water line. Make sure that the insulation is against the top
cover of the heater.
Fit T & P valve insulation over valve. Make sure that the insulation
does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
Section B: Using the
(Sweat) Soldering Method
1. Position the water heater so that the existing piping and
electrical hookup will require the shortest distance
between connections. Make sure that you are able to reach
the drain valve and all access panels when the water
heater is in place. This will make it easy to service the
water heater. The water heater must be level before you
begin the piping.

If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve,
water meter with a check valve, etc. . . in the cold water
supply; means shall be provided to control thermal
expansion. Contact the water supplier or plumbing
contractor on how to control this situation.
2. The pipe cutter is simple to use, screw the adjustment
knob until the opening of the jaws will allow the cutters to
be placed around the pipe. Then close the adjustment
until the cutting blade is just tight against the pipe. Do not
over tighten. Make one or two revolutions of the cutter
around the pipe. Tighten the adjustment knob slightly, and
revolve the cutters around the pipe once again. Continue
this procedure until the pipe is completely cut in two.
3. Using the diagram map out the installation. Screw the
nipples into the tank and the fittings onto the nipples, hand
tight. Then measure and cut the copper tubing. Remove
the nipples and fittings, then go to the next step.
4. Put two or three turns of Teflon tape or pipe joint compound
around both the threaded end of the 3/4” x 3” nipples, and
using a pipe wrench, tighten the nipples into the “HOT”
and “COLD” fittings on the water heater.
5. Cleaning and brushing the piping and fittings is one of the
most important aspects of sweat connections. Clean the
ends of each piece of copper with emery cloth as shown.
Clean the inside of each sweat fitting with a wire brush as
shown. Make sure you do not touch the cleaned areas.
6. The 3/4” female threaded to sweat connectors and two
pieces of copper pipe to connect the water heater to the
house plumbing should be cleaned, fluxed and
assembled. Do not screw the connectors into the
nipples in the tank before soldering.
7. Solder pipe/connector assembly as shown. When solder
flows into and completely around the joint, you should
remove the solder and the heat immediately.
8. Using your pipe wrench, secure the pipe/connector
assemblies onto the nipples.
9. Flux the ends of piping and inside the couplings.
10. Put the pipes and coupling together and solder as shown.
Solder the top first, and then quickly solder the bottom.
11. Flux the ends of the length of pipe cut for the T & P and the
inside of the 3/4” male threaded to sweat connector and
90° sweat elbow. Then solder this assembly together. Do
not screw the connector into the Temperature-Pressure
Relief Valve before the assembly is soldered together.
12. Using your pipe wrench, screw the assembly into the
Temperature-Pressure Relief Valve.
13. Flux the inside of the 90° elbow and the length of pipe to be
run to an adequate drain, and solder them together.
14. After checking that all connections are tight and the drain
valve near the bottom of the water heater is closed, go to
“Filling the Water Heater” section and then to “Wiring” in
the Installing the New Water Heater” section.

Temperature-Pressure Relief Valve
WARNING
At the time of manufacture this water heater was provided with
a combination temperature-pressures relief valve certified by
a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or
materials, as meeting the requirements for Relief Valves and
Automatic Gas Shut-off Devices for Hot Water Supply Systems,
and the current edition of ANSI Z21.22 • CSA 4.4 and the code
requirements of ASME. If replaced, the valves must meet the
requirements of local codes, but not less than a combination
temperature and pressure relief valve certified as meeting the
requirements for Relief Valves and Automatic Gas Shut-off
Devices for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4
by a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or
materials.
The valves must be marked with a maximum set pressure
not to exceed the marked hydrostatic working pressure of the
water heater (150 lbs. p.s.i.) and a discharge capacity not less
than the water heater input rate as shown on the model rating
plate. (Electric heaters - watts divided by 1000 x 3412 equal
BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve complying with ANSI Z21.22
• CSA 4.4 and ASME, may require a valve model different from
the one furnished with the water heater.
Compliance with such local requirements must be satisfied
by the installer or end user of the water heater with a locally
prescribed temperature-pressure relief valve installed in the
designated opening in the water heater in place of the factory
furnished valve.
For safe operation of the water heater, the relief valves must
not be removed from their designated openings or plugged.
The temperature-pressure relief valves must be installed
directly into the fitting of the water heater designated for the
relief valve. Provide tubing so that any discharge will exit only
within 6 inches above, or at ant distance below the structural
floor. Be certain that no contact is made with any live electrical
part. The discharge opening must not be blocked or reduced
in size under any circumstances. Excessive length, over 30
feet, or use of more than four elbows can cause restriction and
reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the relief
valves and the tank. Do not connect tubing directly to discharge
drain unless a 6" air gap is provided. To prevent bodily injury,
hazard to life, or property damage, the relief valves must be
allowed to discharge water in quantities should circumstances
demand. If the discharge pipes are not connected to a drain or
other suitable means, the water flow may cause property
damage.
The Discharge Pipe:
• Must not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
• Must not be plugged or blocked.
• Must be of material listed for hot water distribution.
• Must be installed so as to allow complete drainage of both
the temperature-pressure relief valve, and the discharge
pipe.
• Must terminate at an adequate drain.
• Must not have any valve between the relief valve and tank.
WARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to ensure
that (1) no one is in front of or around the outlet of the
temperature-pressure relief valve discharge line, and (2) the
water manually discharged will not cause any bodily injury or
property damage because the water may be extremely hot.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately, close the cold
water inlet to the water heater, follow the draining instructions,
and replace the temperature-pressure relief valve with a new
one.
This water heater is provide with a combination Temperature-Pressure Relief Valve listed as complying
with the standard for Relief Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems,
ANSI Z21.22 and the code requirements of ASME.
Your local jurisdictional authority, while mandating the use of a Temperature-Pressure Relief Valve
complying with ANSI Z21.22 and ASME, may require a valve model different from the one furnished
with the water heater.
Compliance with such local requirements must be satisfied by the installer or end user of the water
heater with a locally prescribed Temperature-Pressure Relief Valve installed in the designated
opening in the water heater.
• If a short shank (less than 2”) temperature-pressure relief valve is to be installed (as shown),
a nipple and coupling must be used.
• If a long shank (2” or longer) is to be installed, do not use the nipple and coupling.
“Install Temperature-Pressure protective equipment required by local codes, but not less than a
combination Temperature-Pressure Relief Valve certified as meeting the requirements for Relief
Valves and Automatic Gas Shut-off Devices for Hot-Water Supply Systems, ANSI Z21.22 by a nationally
recognized testing laboratory that maintains periodic inspection of production of listed equipment
or materials. The valve must be oriented, provided with tubing, or otherwise installed so that discharge
can exit only within 6 inches above, or at any distance below the structural floor, and cannot contact
any live electrical part.”
For safe operation of the water heater, the Relief Valve must not be removed or plugged.
See manual heading - “Temperature-Pressure Relief Valve” for installation and maintenance of Relief
Valve, discharge line and other safety precautions.

WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to
produce hot water. Water heated to a temperature which will
satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact.
Some people are more likely to be permanently injured by hot
water than others. These include the elderly, children, the infirm,
or physically/mentally handicapped. If anyone using hot water
in your home fits into one of these groups or if there is a local
code or state law requiring a certain temperature water at the
hot water tap, then you must take special precautions. In
addition to using the lowest possible temperature setting that
satisfies your hot water needs, some type of tempering device,
such as a mixing valve, should be used at the hot water taps
used by these people or at the water heater. Mixing valves are
available at plumbing supply or hardware stores. Follow
manufacturers instructions for installation of the valves, Before
changing the factory setting of the thermostat, read the
“Temperature Regulation” section in this manual.
WARNING
Never allow small children to use a hot water tap, or to draw
their own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
Thermostat
The thermostat(s) of this water heater have been factory set at
a position which approximates 120°F (Hot) to reduce the risk
of scald injury.
The upper thermostat is factory set at a position which
approximates 120°F (HOT) and is adjustable if a different water
temperature is desired. Read all warnings in this manual and
on the water heater before proceeding.

Start Up Conditions
THERMAL EXPANSION
Water supply systems may, because of such events as high
line pressure, frequent cut-offs, the effects of water hammer
among others, have installed devices such as pressure
reducing valves, check valves, back flow preventers, etc...to
control these types of problems. When these devices are not
equipped with an internal by-pass, and no other measures are
taken, the devices cause the water system to be closed. As
water is heated, it expands (thermal expansion) and closed
systems do not allow for the expansion of heated water.
The water within the water heater tank expands as it is heated
and increases the pressure of the water system. If the relieving
point of the water heater's temperature-pressure relief valve is
reached, the valve will relieve the excess pressure. The
temperature-pressure relief valve is not intended for the
constant relief of thermal expansion. This is an unacceptable
condition and must be corrected.
It is recommended that any devices installed which could create
a closed system, have a by-pass and/or the system have an
expansion tank to relieve the pressure built by thermal
expansion in the water system. Expansion tanks are available
for ordering through a local plumbing contractor. Contact the
The lower thermostat is factory set at a position which
approximates 120°F (HOT) and is adjustable if a different water
temperature is desired. Read all warnings in this manual and
on the water heater before proceeding.

Thermostat Adjustment
On dual element models, both the upper and lower thermostats
have been factory set at HOT (approximately 120°F) to reduce
the risk of scald injury.
The upper and lower thermostats are adjustable if a different
water temperature is desired. Read all warnings in the
“Temperature-Regulation” section before proceeding.
NOTE: It is not necessary to adjust the upper thermostat.
However, if it is adjusted above the factory set point (120°F/
HOT) it is recommended that it not be set higher than the lower
thermostat setting.
To adjust the temperature setting for both upper and lower
thermostats, proceed as follows:
1. Turn “OFF” the electrical power to the water heater at the
junction box.
WARNING
HAZARD OF ELECTRICAL SHOCK! Before removing any
access panels or servicing the water heater, make sure the
electrical supply to the water heater is turned “OFF”. Failure to
do this could result in DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
2. Take off the (upper and lower) access panel and insulation
block(s) and pad(s).
3. The slotted adjustment (using a screwdriver) can be turned
clockwise ( ) to increase the temperature, or counter

STRANGE SOUNDS
Possible noises due to expansion and contraction of some
metal parts during periods of heat-up and cool-down do not
represent harmful or dangerous conditions.
Operational Conditions
SMELLY WATER
In each water heater there is installed at least one anode rod
(see parts section) for corrosion protection of the tank. Certain
water conditions will cause a reaction between this rod and
the water. The most common complaint associated with the
anode rod is one of a “rotten egg smell”. This odor is derived
from hydrogen sulfide gas dissolved in the water. The smell is
the result of four factors which must all be present for the odor
to develop:
A. A concentration of sulfate in the supply water.
B. Little or no dissolved oxygen in the water.
C. A sulfate reducing bacteria within the water heater. (This
harmless bacteria is non-toxic to humans.)

WARNING
HAZARD OF ELECTRICAL SHOCK! Before removing any
access panels or servicing the water heater, make sure the
electrical supply to the water heater is turned “OFF”. Failure to
do this could result in DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
2. Remove the two screws securing the access panel and
remove panel.
3. Remove the insulation block and pad.
4. Reset the high limit by pushing in the red button marked
“RESET”.
5. Replace the insulation block and pad so that it completely
covers the thermostat and element.
6. Replace the access panel.
7. Turn “ON” electric power to the water heater.
CAUTION
If the high limit must be reset again, call a serviceman to find
out why the high limit turned “OFF” the electric power.
NOT ENOUGH OR NO HOT WATER
• In a new installation, the water heater may not be properly
connected. Make sure the cold water supply valve is open.
Review and check piping installation. Make sure that the
cold water line is connected to the cold water inlet to the
water heater and the hot water line to the hot water outlet on
the water heater.
• Make sure the electrical supply to your water heater is “ON”.
• Check for loose or blown fuses in your water heater circuit.
Circuit breakers weaken with age and may not handle their
rated load and should be replaced.
• Make certain the disconnect switch, if used, is in the “ON”
position.
• Check to see the electric service to your house has not
been interrupted. If this is the case, contact the electric utility.
• Are the thermostats set to the desired temperature? See
“Temperature Regulation” section.
• If you had experienced very hot water and now no hot water,
the problem may be due to the high temperature shut-off
system. See “High Temperature Shut-Off System” in the
“Operational Conditions” section.
D. An excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.
Smelly water nay be eliminated or reduced in some water heater
models by replacing the anode(s) with one of less active
material, and then chlorinating the water heater tank and all
hot water lines. Contact the local water heater supplier for
further information concerning an Anode Replacement Kit
#9000029 and this Chlorination Treatment.
If the smelly water persists after the anode replacement and
chlorination treatment, we can only suggest that continuous
chlorination and filtering conditioning equipment be considered
to eliminate the water problem.
Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater is voided.
“AIR” IN HOT WATER FAUCETS
WARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot
water system that has not been used for a long period of time
(generally two weeks or more). Hydrogen gas is extremely
flammable and explosive. To prevent the possibility of injury
under these conditions, we recommend the hot water faucet
be opened for several minutes at the kitchen sink before any
electrical appliances which are connected to the hot water
system are used (such as a dishwasher or washing machine).
If hydrogen gas is present, there will probably be an unusual
sound similar to air escaping through the pipe as the hot water
faucet is opened. There must be no smoking or open flame
near the faucet at the time it is open.
RUMBLING NOISE
In some water areas, scale or mineral deposits will build up
on your heating elements. This buildup will cause a rumbling
noise. Follow “Element Cleaning/Replacement” instructions
to clean and replace the elements.
HIGH TEMPERATURE SHUT-OFF SYSTEM
The water heater has a high limit shut-off system with a reset
button located on the thermostat.
Follow the resetting instructions which refer to the high limit
behind the access panel.
• Before beginning, turn “OFF” electrical power supply to the
water heater.

16
• During very cold weather, the incoming water will also be
colder and it will require a longer time to become heated.
• The hot water usage may exceed the capacity of the water
heater. If so, wait for water heater to recover after abnormal
demand. Also examine pipes and faucets for possible water
leaks.
• If you can not determine the problem, then call a local
serviceman.
WATER IS TOO HOT
Adjust the thermostat to a lower setting. See the “Temperature-
Regulation” section.
Temperature-Pressure
Relief Valve Operation
The temperature-pressure relief valve must be manually
operated at least once a year.
WARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to ensure
that (1) no one is in front of or around the outlet of the
temperature-pressure relief valve discharge line, and (2) the
water manually discharged will not cause any property damage
or bodily injury. The water may be extremely hot.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold
water inlet to the water heater, follow the draining instructions,
and replace the temperature-pressure relief valve with a new
one.
Failure to install and maintain a new properly listed temperature-
pressure relief valve will release the manufacturer from any
claim which might result from excessive temperature or
pressure.
WARNING
If the temperature-pressure relief valve on the appliance weeps
or discharges periodically, this may be due to thermal
expansion. Your water heater may have a check valve installed
in the water line or a water meter with a check valve. Consult a
local plumbing contractor and/or the local water utility for
further information. Do not plug the temperature-pressure relief
valve.
Draining
The water heater should be drained if being shut down during
freezing temperatures. Also, periodic draining and cleaning of
sediment from the tank may be necessary.

Anode Rod Inspection
NOTE: Not applicable to Compact models of 20 gallons and
less.
The anode rod is used to protect the tank from corrosion. Most
hot water tanks are equipped with an anode rod. The
submerged rod sacrifices itself to protect the tank. Instead of
corroding the tank, water ions attack and eat away the anode
rod. This does not affect the water’s taste or color. The rod
must be maintained to keep the tank in operating condition.
Anode deterioration depends on water conductivity, not
necessarily water condition. A corroded or pitted anode rod
indicates high water conductivity and should be checked and/
or replaced more often than an anode rod that appears to be
intact. Replacement of a depleted anode rod can extend the
life of your water heater. Inspection should be conducted by a
qualified technician, and at a minimum should be checked
annually after the warranty period.
Drain Valve Washer Replacement
NOTE: For replacement, use a 17/32" x 13/64" x 1/8" thick
washer available at your nearest hardware store.
1. Before beginning turn “OFF” the electrical power supply to
the water heater.
WARNING
HAZARD OF ELECTRICAL SHOCK! Before removing any
access panels or servicing the water heater, make sure the
