a combinationtemperature and pressurerelief valve certified as
meeting the requirements for Relief Valves and Automatic Gas
ShutoffDevicesfor Hot Water SupplySystems,ANSI Z21.22 by a
nationally recognized testing laboratory that maintains periodic
inspectionofproductionof listedequipmentor materials.
The valve must be marked with amaximum set pressurenot
to exceed the marked hydrostatic working pressure of the
water heater (I 50 Ibs./sq.in.)and a discharge capacity not less
than the water heater input rate as shownon the model rating
plate. (Electric heaters - watts divided by 1000 x 3415 equal
BTUiHr. rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve complying with ANSI Z21.22
andASME, mayrequire a valvemodel differentfrom the onefur-
nishedwith the water heater.
Compliancewith suchlocalrequirements must be satisfiedbythe
installeror end user ofthe water heater with a locallyprescribed
temperature-pressure reliefvalveinstalledin the designatedopen-
ingin the water heater inplaceof the factory furnished valve.

• Must not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplingsor other restrictions.
Must not be pluggedor blocked.
Must be of material listedfor 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 anyvalve between the relief valveand 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 bod-
ily injury, or property damage.
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature 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
physlcallylmentally 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 tem-
perature water at the hot water tap, then you must take
special precautions. In addition to using the lowest possi-
ble 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 set-
ting on the thermostat, read the "Temperature
Regulation" section in this manual
_WARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE
ONLY: This water heater isequipped 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
accessareas.
c. DO NOT cover or remove operating instructions, and

Removing the Old Water
Heater
Turn "OFF" etectricai supply to the water heater.
tf you have copper piping to the water
heater, the two copper water pipes can be ..........
cut with a hacksaw approximately four
inches 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 reliefvalve drain line.
When the water heater is drained, discon-
nect the hose from the drain valve, Close
the drain valve. The water heater is now
completely disconnected and ready to be
removed,
-Turn "OFF" the water supply to the
water heater at the water shutoffvalve or
water meter.
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 wilt relieve pressure in the
water heater and speed draining.
O
If you have galvanized pipe to the water
heater, loosen the two galvanized pipes
with a pipe -wrenchat 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 disconnect-
ed and ready to be removed.

Locating the New Water
Heater
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 arid for the most
economical use of the appliance. This water heater is not intend-
ed 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 cen-
tra]ized with the water piping system as possible. This water
heater, as well as all water heaters, witl eventually leak. Do not
instal! without adequate drainage provisions where water flow
will cause damage.
_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. When such
locations cannot be avoided, a suitable drain pan should
be installed under the water heater. Drain pans are avail-
able at your local Sears Store. Such a drain pan must be
piped to an adequate drain. Under no circumstances is
the manufacturer or Sears to be held liable for any water
damage in connection with this water heater.
Facts to Consider About The
Convertible Lower Element
The Upper Element (if a double element model), is a conven-
tional 3800 watt element -which only operates at its rated
wattage on 240 volts. (See rating plate on water heater).
The Lower Element of the water heater can be converted from
operation at 3800 watts to 5500 watts on a 240 volt system.
Read and follow water heater warnings and instruc6ons.If a_er
reading these instructions in this manual, if you do not under_
stand any portion, call Sears Service Center.
_I_WARNI NG
Before making the conversion to 5500 watts, check the
(I) power supply...must be 240 volts, (2) wiring...10 gauge
AWG @ type T.W. 60c or equivalent, and (3) Circuit
breakers or fusing...capable of 30 amp loading. Also, the
installation must conform with this manual, local codes
and electric utility rules. Failure to comply can result in
death, serious bodily injury, or property damage.
ACAUTION
INSTALLATION IN RESIDENTIAL GARAGES: The
water heater must be located andlor 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.
NOTE: Whether or not the element conversion is made the
model rating plate must be marked. Using a hardpoint ink
pen, check the appropriate block within the model rating
plate, which is located adjacent to the lower access panel.

HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature 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
physicallylmentally 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 tem-
perature water at the hot water tap, then you must take
special precautions. In addition to using the lowest possi-
ble 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. Hixing valves are available at plumbing supply or
hardware stores. Follow manufacturers instructions for
installation of the valves. Before changing the factory set-
ting on the thermostat, read the "Temperature
Regulation" section in this manual.
The illustration shows the attachment of the water i ing to the
water heater. The water heater is equipped with % inch water
connections.
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 local utility
or local Sears Service Center on how to control this situation.

NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adaptor to the cold water inlet connec-
tion. Do not solder the cold water supply llne directly to the
cold water inlet. It w_ harm the dip tube and damage the
tank.
1. Look at the top cover of the water heater. The water outlet is
marked hot. Put two or three turns of teflon tape around the
threaded end of the threaded-to-sweat coupling and around
both ends of the "%"threaded nipple. Using flexible connec-
tors, connect the hot water pipe to the hot water outlet of the
water heater.
2. Look at the top cover of the water heater. The cold water inlet
is marked cold. Put two or three turns of teflon tape around
the threaded end of the threaded-to-sweat coupling and
around both ends of the %" threaded nipple. Using flexible
connectors, connect the cold water pipe to the cold water inlet
of the water heater.
NOTE: Yourwater heater is super insulated to minimize heat
loss from the tank. Further reduction in heat toss can be
accomplished by insulating the hot water lines from the
water heater.

Relief Valve
_kWARNING
At the time of manufacture this water heater was provid-
ed with a combination temperature-pressures relief valve
certified by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed equip-
ment or materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot Water
Supply Systems, and the latest edition of ANSI Z21.22 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 Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22 by a nationally recognized testing
laboratory that maintains periodic inspection of produc-
tion 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 (i 50 lbs.lsq, in.) and a discharge capacity
not lessthan the water heater input rate as shown on the
model rating plate. (Electric heaters - watts divided by
1000x 3415 equal BTU/Hr. rate.)
Your localjurisdictional authority, while mandating the use
of a temperature-pressure relief valve complying with
ANS! Z21.22 and ASME, may require a valve model differ-
ent 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
_art. The discharge opening must not be blocked or
reduced in size under any circumstances. Excessivelength,
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 llfe, 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 haveany reducing couplings or other
restriction.
-- Must not be pluggedor blocked.
Must be of material listed for hot water distribution.
Must be installed soasto allow complete drainage of
both the temperature-pressure relief valve, and the dis-
charge pipe.
-- Must terminate at anadequate drain.
Must not have any valve between the relief valve and
tank.
_I_WARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to
ensure that (I) 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 manuaUy operating the valve, it fails to complete-
ly reset and continues to release water, immediately,
close the cold water inlet to the water heater, follow the
draining instructions, and replace the temperature.pres-
sure relief valve with a new one.
