QTurn "OFF" electricalsupply to the water heater.

Q Turn "OFF" the water supply to the

water heater at the water shutoffvalve or water meter.

If you have copper piping to the water

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.

Q Check to make the electrical supply isagain

Qb.

If you have galvanized pipe to the water heater, loosen the twogalvanized 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 disconnect- ed and ready to be removed.

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.

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.

Filling the Water Heater

To fill the water heater with water:

Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of

the water heater. Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open

when the water heater is in use. To insure complete filling of the tank, allow air to exit by

opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will Iet air out of the

water heater and the piping.

A CAUTION

Never use this water heater unless it is completely full of

water. To prevent damage to the tank and heating ele-

ment, the tank must be filled with water. Water must flow from the hot water faucet before turning "ON"

power.

Check all new water piping for leaks. Repair as needed.

Converting the Lower

Element

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.

Necessary element conversion parts are located in a small bag contained within the electrical junction box on top of the water

heater.

These instructions only cover the conversion of the convertible element, read this entire manual before attempting to install or

operate the water heater. The water heater is factory set to oper-

ate at 3800 watts. The lower element can be converted to oper-

ate at 5500 watts. Refer to the "Facts to Consider About the

Convertible Lower Element" section.

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).

Service

Before calling for repair service, read the Start Up Conditions

and Operational Conditions found in the Troubleshooting Guide of this manual.

If a condition persists or you are uncertain about the operation of the water heater, let a qualified person check it out.

Troubleshooting Guide

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 flowpreventers, 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 (ther-

mal expansion) and closed systems do not allow for the expan- sion 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 cor-

rected.

It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an expan-

sion 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.

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 company.

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

Troubleshooting Guide section.

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 the Sears Service Department.

WATER IS TOO HOT

Adjust the thermostat to a lower setting. See the "Temperature

Regulation" section.
