Safety Precautions

A WARNING

Improper installation, adjustment, alteration, service or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manual for assis tance or consult your local Sears Service Center for further information.

AWARNING

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 materias, 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 AutcHTiatic 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 marked hydrostatic working pressure of the water heater (ISO lbs./sq. 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 valve.

For safe operation of the water heater, the relief valve must not be removed from it^ 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 pnmde 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, 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 vaJve and tank.

AWARNING

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, SERI OUS BODILY 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

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.

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 voltage other than the one shown on the model rating plate. Failure to use the correct voltage can cause

problems which cifTresTjT£1n"DEArH,'SERlbUS BODILY INJURY. OR PROPlBXYJ?AMAGE-Jtyou have any ques

tions or doubts consult your electric company.

Removing the Old Water Heater

^^Turn “OFF” electrical supply^ to the water heater.

^Ja. 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 short. Additional cuts can be made later if necessary. Disconnect the tempera

ture-pressure relief valve drain line. \)№en 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.

Turn “OFF” the water supp^ to t water heater at the water shutoff valve 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 will relieve pressure in the water heater and speed draining.

the

b. 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 disconnect

ed and ready to be removed.

AWARNING

The water passing out of the drain valve may be extreme ly hot. To avoid being scalded, make sure all connections are tight and that the water flow is directed away from any person.

^ 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.

AWARNING

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.

Installation Instructions (cont'd)

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 econornical use of the appliance. This water heater is not intended for outdoor installation.

Whether replacing an old water hearer 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. 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 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 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 instructions. If after reading these instructions in this manual, if you do not under stand any portion, call Sears Service Center.

AWARNING

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.

Water Piping

A WARNING

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a tem perature which will satisfy space heating, ciothes washing, dish washing, and other sanitizing needs can scaid and permanently injure you upon contact. Some peopie are more itkely to be permanentiy injured by hot water than others. These inciude the eiderly, children, the infirm, or physicalty/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 Vt" 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.

Relief Valve

AWARNING

At the time of manufacture this water heater was provided with a combination temperature-pressures relief vai ve cer tified by a nationaiiy recognized testing iaboratory 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 Z2I.22 by a nationally recognized testing lAoratory 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 (ISO lbs./sq. 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 v^ve 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 wll exit only within 6 inches above, or at any distance below the structural floor. Be cer tain 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

restriction. * 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 dis charge pipe.

* Must terminate at an adequate drain. * Must not have any valve between the relief valve and

tank.

AWARNING

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.
