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 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 Shutooff
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 Ibs.p.s.i.) and a discharge capacity not less than
the water heater input rate as shown on the model rating plate.
(Electric heaters owatts 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 temperatureopressure 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 temperatureopressure relief valve, and the discharge
pipe.
Must terminate at an adequate drain.
Must not have any valve between the relief valve and tank.
,, Before removing any access
panels or sep¢icing the water
heater, make sure the electrical
supply to the water heater is
_d"OFF".
" Failure to do this could result in
death, serious bodily injury, or

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, a
means such as a mixing valve, shall 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

Removing the Old Water Heater
¢
1. Turn "OFF" electrical supply to the water heater.
4. Check again to make sure the electrical supply is turned
'OFF" to the water heaten 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
shorL 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.
2. Turn "OFF" the water supply to the water heater at the water
shut-off valve or water meter.
3. Attach a hose to the water heater drain valve and put the
other end in a floor drain or outdoors. Open the water heater
drain valve. Open a nearby hot water faucet which will relieve
pressure in the water heater and speed draining.
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.
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.

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 aid water heater or putting the water
heater in a new location, the following critical points must be
observed.
• 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.
Property Damage Hazard
-All water heaters eventually leak
. Do not install without adequate drainage.
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. When such locations cannot be
avoided, a suitable drain pan should be installed under the
water heater. Drain pans are available at your local Sears stores.
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.
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.
*The location selection must provide adequate clearances for
servicing and proper operation of the water heater.
Water Piping

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, a
means such as a mixing valve, shall 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

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.

Anode Rod _nspection
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
Sears service 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. For ordering a
replacement washer, refer to the "Parts Order List" section.
• Before beginning turn 'OFF" the electrica! power supply to
the water heater.
• Follow "Draining" instructions in the "Service and
Adjustment" section.
• Turning counter clockwise, remove the hex cap below the
screw handle.
• Remove the washer and put the new one in place.
• Screw the handle and cap assembly back into the drain valve
and retighten using a wrench. DO NOT OVER TIGHTEN.
• Follow 'Filling the Water Heater" instructions in the
'lnsta!lation Instructions" section.
• Check for leaks.
• Turn 'ON" electric power to the water heater.

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. Thermal expansion tanks are available from Sears
stores and through the Sears Service Centers. Contact the
local plumbing inspector, water supplier and/or the Sears
Service Center for assistance in controlling these situations.

Strange Sounds
Possible noises due to expansion and contraction of some
metal parts during periods of heat-up and coo!-down do not
represent harmful or dangerous conditions.
2O
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'L This odor is derived
from hydrogen sulfide gas dissolved in the water. The smell is
the result of four factors which must al! be present for the odor
to develop:
*A concentration of sulfate in the supply water.
*Little or no dissolved oxygen in the water.
*A sulfate reducing bacteria within the water heater. (This
harmless bacteria is non-toxic to humans.)
*An excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.
Smelly water may 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 al!
hot water lines. Contact the local Sears Service Center for
further information concerning an Anode Replacement Kit
#9001453 and this Ch!orination Treatment.
