perature whichwill satisfy spaceheating, clotheswashing,

dish washing, and other saniUzing needs can scald and

permanently injure you upon contact. Some people are
more likelyto be permanently injured by hot water than

others. These includethe elderly,children, the infirm, or I
physicallylmentally handicapped. If anyone using hot

water in your home fits into one of these groups or if

there is a localcode or state law requiring a certain tem-
perature water at the hot water tap, then you must take
specialprecautions. In addition to usingthe 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 valvesare availableat_plumbingsupplyor

hardware stores. Follow manufacturers instr_,ctionsfor
installationof the valves.Before changingthe factory set-

ting on the thermostat, read the "Temperature

Regulation" sectioninthismanual.

water meter.

If you have copper piping to the water

a.

heater, the two copper water pipes ,canbe
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 tempera-

ture-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 readyto be removed.

QAttach 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.

AWARNING I

The water passingout of the drain valvemay beextreme- I
ly hot. To avoidbeing scalded, make sure all connections

are tight and that the water flow ,s directed away from
anyperson.

Installation Instructions (cont'd)

Facts to Consider About the Facts to Consider About The
Location Convertible Lower Element

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.

_,CAUTION

WATER HEATERS EVENTUALLY LEAK: Installation of

the water heater must beaccomplishedin sucha manner
that if the tank or any connectionsshouldleak, the flow of
water will not causedamageto the structure. When such
locationscannot be avoided, a suitable drain pan should
be installed under the water heater. Drain pansare avail-
able at your local Sears stores. Sucha drain pan must be
piped to an adequate drain. Under no circumstances is
the manufacturer or Searsto be held liablefor anywater
damage in connectionwith thiswater heater.

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 24O 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 Sears Service Center.

_,WARNING

Before making the conversionto 5500 watts, check the
(I) power supply...must be 240volts,(2) wiring...10gauge

AWG, Type TW, 60oc or equivalent, and (3) Circuit
breakers or fusing...capableof 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 J

INSTALLATION IN RESIDENTIAL GARAGES: The J
water heater must be located and/or protected so it is

not subjectto physicaldamage by a moving vehc e.

• 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.

Water Piping

&WARNING

HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-

perature which will satisfyspaceheating,clothes washing,
dish washing, and other sanitizing needs can scald and
permanently injure you upon contact. Some people are
more likelyto 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-

Jerature water at the hot water tap, then you must take

specialprecautions. In addition to usingthe 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 valvesare availableat plumbing supplyor

hardware stores. Follow manufacturers instructions for
installationof the valves.Before changingthe factory set-

ting on the thermostat, read the "Temperature

Regulation"section in this manual.

The illustration shows the attachment of the water plpin_ to the

water heater. The water heater is equipped with ¾ 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. Do not solder the cold water supply fine directly to the
cold water inlet. It will harm the dip tube and damage the

both ends of the 3A"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. Further reduction in heat loss can be
accomplished by insulating the hot water lines from the

water heater.

Relief Valve

,&WARNING

At the time of manufacturethis water heater wasprovided
with a combinationtemperature-pressuresrelief valvecer-
tified by a nationally recognized testing laboratory that
maintains periodic inspectionof productionoflistedequip-
ment or materials, as meeting the requirements for Relief

Valvesand Automatic Gas Shutoff Devicesfor Hot Water
SupplySystems,andthe 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 pressurerelief valve
certified as meeting the requirements for ReliefValvesand

Automatic Gas Shutoff Devices for Hot Water Supply
Systems,ANSI Z21.22 by a nationally recognized testing

laboratory that maintainsperiodicinspectionof production
oflistedequipmentor materials.
The valve must be marked with a maximum set pressure
not to exceed the marked hydrostaticworking pressureof
the water heater (150 Ibs./sq.in.) and a dischargecapacity
not lessthan the water heater input rate as shownon the
model rating plate. (Electric heaters - watts divided by

1000x 3415equal BTU/Hr. rate.)

Yourlocaljurisdictionalauthority, while mandatingthe use
of a temperature-pressure relief valve complying with
ANSI 721.22 and ASME, may require a valve model differ-

ent from the onefurnishedwith the water heater.
Compliancewith suchlocal requirements must be satisfied

_y the installer or end user of the water heater with a
ocally prescribed temperature-pressure relief valve

nstalled in the designatedopeningin the water heater in

placeof thefactory furnishedvalve.
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 designatedfor
the relief valve. Positionthe valve downward and provide
tubing so that any dischargewill exit only within 6 inches
above, or at anydistancebelowthe structuralfloor.Be cer-
tain that no contact is made with any live electrical part.
The dischargeopeningmust not be blockedor reduced in
size under any circumstances. Excessivelength, over 30

feet, or useof more than four elbowscancauserestriction
and reduce the dischargecapacityofthe valve.

No valveor other obstructionisto be placed between the
relief valve and the tank. Do not connect tubingdirectlyto

dischargedrain unlessa 6" air gap is provided.To prevent

bodilyinjury, hazard to life, or property damage,the relief

valve must be allowed to discharge water in quantities
shouldcircumstancesdemand. If the dischargepipe is not

connected to a drain or other suitable means, the water
flow may causeproperty damage.
The DischargePipe:

Must not be smaller in size than the outlet pipe size of
the valve, or have any reducing couplings or other

restriction.

Must not be pluggedor blocked.
Must beofmaterial listed for hot water distribution.

Must be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the dis-
chargepipe.
Mustterminate at anadequate drain.
Must not have any valve between the relief valve and

tank.

,&WARNING

The temperature-pressure relief valve must be manually
operated at least oncea year. Caution shouldbe taken to

ensure that (I) no one is infront of or around the outlet
of the temperature-pressure relief valve discharge line,
and (2) the water manually dischargedwill not causeany

bodily injury or property damage becausethe water may
be extremely hot.

If after manuallyoperating the valve,it failsto 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 anew one.
