Safety
A WARNING
Improper installation, adjustment, alteration, service or mainte
nance can cause DEATH, SERIOUS BODILY INJURT, OR PROP
ERTY DAMAGE. Refer to this manual for assistance or consult
your local Sears Service Center for further information.
A WARNING
At the time of manufacture this water heater was provided with
a combination temperature-pressures relief valve certified by a
nationally rec(^niz«J testing laboratory that maintains periodic
inspection of production of listed equipment 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 Z2I.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 Z2I.22 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 marlœd hydrostatic working pressure of the water
heater (ISO IbsJsq. in.) 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 3415 equal BTU/Hr.
rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve complying witii ANSI Z2I.22
and ASME, may require a valve model different from the one fur
nished 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 pre
scribed temperature-pressure relief valve installed in the desig
nated opening in the water heater in place of the factory fornished valve.
For safe operation of the water heater, the relief valve must not
be removed from itis 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 dis
charge will exit only within 6 inches above, or at any distance
below the structuré 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, haz
ard 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.
A 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 INJU'
OR PROPERTY DAMAGE.
AWARNING
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 permanent
ly 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 locai code or state iaw requiring a cer
tain temperature 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 setting on the thermo
stat, read the "Temperature Regulation" section in this
manual.
AWARNING
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 volt
age 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 PROP
ERTY DAMAGE. If you have any questions or doubts consult
your electric company.
AWARNING
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 cover or remove operating instructions, and safe
ty related warning labels and materials affixed to the water
heater.
AWARNING
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.
A CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the
water heater must be accomplished in such a manner that tf
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 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.

any person.
^4 J 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.
A 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 cuise staining.
Installation Instructions (contad)
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 consid
eration 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.
• 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.
A 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 avoid
ed, 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. Under no circumstances is the manufacturer or
Sears to be held liable for any water damage in connec
tion 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 instructions. If after
reading these instructions in this manual, if you do not under
stand any portion, call Seats Service Center,
A WARNING
Before making the conversion to 5500 watts, check the
(I) power supply...must be 240 volts, (2) wiring... 10 gauge
AWG, Type TW, 60*C 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.
A 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.
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 hard point ink
pen, check the appropriate block within the model rating
plate, which is located adjacent to the lower access panel.
Installation Instructions (cont*d)
Water Piping
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
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 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.
The illustration shows the attachment of the water piping to the
water heater. The water heater is equipped with Va 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 adapter to the cold water inlet connec
tion. Oo not solder the cold water supply line directly to the
cold water inlet. It will harm the dip tube and damage the
tank.
• 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.
• 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; Your water heater is super insulated to minimize
heat loss from the tank. Farther reduction in heat loss can be
accomplished by insulating the hot water lines from the
water heater.

Temperature-Pressure Relief Valve
A 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
Shutoff Devices for Hot Water Supply Systems, and the latest
edition of ANSI Z2I.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 Z2I.22 by a nationally recognized testing laboratory that
maintains peric^ic 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 (ISO IbsJsq. in.) 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 3415
equal BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve complying with ANSI Z2I.22
and ASME, may require a valve model different from the one fur
nished 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 pre
scribed temperature-pressure relief valve installed in the desig
nated opening in the water heater in place of the factory fur
nished vialve.
For safe operation of the water heater, the relief valve must not
be removed from itis 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 dis
charge 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
i pipe.
' * Must terminate at an adequate drain.
I * Must not have any valve between the relief valve and tank.
A 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 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 drain
ing instructions, and replace the temperature-pressure
relief valve with a new one.
WARNING “RELIEF VALVE OPENING
