Turn "OFF" electrical supply to the water heater.

Q Turn "OFF" the water supply to the

water heater at the water shutoff valve 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 will relieve pressure in the water heater and speed draining.

If 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 con- nect 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, dis- connect the hose from the drain valve.

Close the drain valve. The water heater

is now completely disconnected and ready to be removed.

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 need- ed when reconnecting the new

water heater. Disconnect the temperature-pressure relief

valve 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 com-

pletely disconnected and ready

to be removed.

WARNING

The water passing out of the drain valve may be extremely hot. To avoid being scalded, make

sure all connections are tight and that the water flow is directed away from any person.

CAUTION

Mineral buildup or sediment may have accumu- lated 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.

Facts to Consider About the Location

You should carefully choose an indoor location for the new water heater, because the placement is a very impor- tant consideration for the safety of the occupants in the

building and for the most economical use of the appli- ance. 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.

1. 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 even- tually 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 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 available at your local Sears Store. Such a drain pan

must be piped to an adequate drain. Under no circum-

stances is the manufacturer or Sears to be held liable for any water damage in connection with this water heater.

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.

2. The location selection must provide adequate clear-

ances for servicing and proper operation of the water

heater.

Water Piping

WARNING

HOTTER WATER CAN SCALD: Water heaters are intend-

ed to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to beper-

manently 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 temperature water at the hot water tap, then you must take special precautions. In

addition to using the lowest possible temperature setting that satisfies your hot water needs, some type of temper-

ing device, such as a mixing valve, should 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 3/4

inch water connections.

If a water heater is installed in a closed water supply sys-

tem; such as one having a back-flow preventer, check valve, water meter with a check valve, etc. in the cold

water supply; means must be provided to control thermal expansion. Contact the local utility or Sears Service

Center on how to control this situation.

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 3/4"threaded nip- ple. Using flexible connectors, connect the hot water

pipe to the hot water outlet on 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 3/4"thread- ed nipple. Using flexible connectors, connect the cold

water pipe to the cold water inlet of the water heater.

NOTE: This water heater is 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.

WARNING

At the time of manufacture this water heater was provided with a combination temperature-pressuresrelief valve certi- fied by a nationally recognized testing laboratory that main- tains 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 Z21.22 and the code requirements of ASME. If replaced, the valve must meet the requirementsof local codes, but not lessthan a combination

temperature and pressure relief valve certified asmeeting 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 peri- odic inspectionof production of listed equipment or materi-

als. The valve must be marked with a maximum set pressurenot

to exceed the marked hydrostatic working pressure of the water heater (150 Ibs./sq. in.) and a discharge capacity not

lessthan the water heater input rate as shown on the model rating plate. (Electric heaters - wattsdivided 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 Z21.22 and ASME, may require a valve model different 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 facto- ry furnished valve.

For safe operation of the water heater, the relief valve must not be removedfrom it's designatedopening or plugged.

The temperature-pressure relief valve must be installed directly into the fittingof the water heater designatedfor the relief valve. Positionthe 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 part. The discharge opening must not be blocked or reduced in size under any

circumstances.Excessivelength, over 30 feet, or useof more than four elbows can cause restriction and reduce the dis-

charge 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 unlessa 6" air gap is provided. To prevent

bodily J_njury,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 I_e smaller in size than the outlet pipe size of the

valve, or have any reducing couplingsor 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 discharge pipe.

--Must terminate at an adequate drain.

--Must not have any valve between the relief valve and tank.

taken to ensure that (1) no one is in front of or around the outlet of the temperature-pressure relief valve dis-

charge 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 com-

pletely rest and continues to release water, immediate- ly, close the cold water inlet to the water heater, follow

the draining instructions, and replace the temperature- pressure relief valve with a new one.

Filling the Water Heater

Wiring

To fill the water heater with water:

1. Close the water heater drain valve by turning the han- dle to the right (clockwise). The drain valve is on the

lower front of the water heater.

2. 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.

3. 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 let air

out of the water heater and the piping.

CAUTION

Never use this water heater unless it is completely

filled with water. To prevent damage to the tank and heating element, the tank must be filled with water.

Water must flow from the hot water faucet before turning "ON" power.

WARNING

HOTTER WATER CAN SCALD: Water heaters are intended

to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and

other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be per-

manently injured by hot water than others. These include

the elderly, children, the infirm, or physically/mentally

using the lowest possible temperature setting that satisfies

your hot water needs, some type of tempering device, such as a mixing valve, should 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 of the

thermostat, read the "Temperature Regulation" section in this manual.

WARNING

Never allow small children to use a hot water tap, or to

draw their own bath water. Never leave a child or handi-

capped person unattended in a bathtub or shower.

Temperature Settings

HOT-Is a thermostat setting of approximatel\

120°F, which will supply hol water at the most economical temperatures.

A-Is a thermostat setting of approximatel\

130°F.

B-Is a thermostat setting of approximatel_

140°F. This is the lowest setting for supply of hot water to dishwashers.

C-Is a thermostat setting of approximately

150°F.

VERY HOT-Is a thermostat setting of approximately

t 60°F. It is recommended that the dial be set

lower whenever possible.

NOTE: Residential electric water heaters will not supply

Start Up Conditions

THERMAL EXPANSION

Water supply systems may, because of such events as high line pressure, frequent cut-offs, the effects of water ham-

mer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, 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 sys- tem to be closed. As water is heated, it expands (thermal 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-pres-

sure 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 corrected.

It is recommended that any devices installed which could create a closed system, have a by-pass and/or the system have an expansion tank to relieve the pressure built by

thermal expansion in the water system. Expansion tanks

are available for ordering through the Sears Service

Center. Contact the local plumbing inspector, water sup-

plier and/or Sears Service Center for assistance in control- ling these situations.

STRANGE SOUNDS

Possible noises due to expansion and contraction of some

metal parts during periods of heat-up and cool-down do

not represent harmful or dangerous conditions.

Operational Conditions

SMELLY WATER

In each water heater there is installed at least one anode rod (see parts section) for corrosion protection of the tank.

Certain water conditions will cause a reaction between this rod and the water. The most common complaint asso-

ciated with the anode rod is one of a "rotten egg smell".

This odor is derived from hydrogen sulfide gas dissolved in the water. The smell is the result of four factors which

must all be present for the odor to develop:

a. a concentration of sulfate in the supply water. b. little or no dissolved oxygen in the water.

c. a sulfate reducing bacteria within the water heater.

(This harmless bacteria is non-toxic to humans.)

d. an excess of active hydrogen in the tank. This is

caused by the corrosion protective action of the anode.

Smelly water may be eliminated or reduced in some water heater models by replacing the anode(s) with one of less active material, and then chlorinating the water heater

tank and all hot water lines. Contact the local Sears Service Center for further information concerning an

Anode Replacement Kit #9001453 and this Chlorination Treatment.

If the smelly water persists after the anode replacement and chlorination treatment, we can only suggest that con-

tinuous chlorination and filtering conditioning equipment

be considered to eliminate the water problem.

Do not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is

voided.

"AIR" IN HOT WATER FAUCETS

WARNING

HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long peri- od of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the

possibility of injury under these conditions, we recom- mend the hot water faucet be opened for several min- utes at the kitchen sink before any electrical appliances

which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound

similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.

RUMBLING NOISE

In some water areas, scale or mineral deposits will build up on your heating elements. This buildup will cause a rumbling noise. Follow "Element Cleaning/Replacement"

instructions to clean and replace the elements.

HIGH TEMPERATURE SHUT OFF SYSTEM

The water heater has a high limit shut off system with a

reset button located on the thermostat.

Follow the resetting instructions which refer to the high limit behind the access panel.

1. Before beginning, turn "OFF" electrical power supply to the water heater.

Operational Conditions

HIGH TEMPERATURE SHUT OFF SYSTEM (cont'd))

WARNING

HAZARD OF ELECTRICAL SHOCK! Before removing

any access panels or servicing the water heater, make sure the electrical supply is turned "off" to the water

heater. Failure to do this could result in death, serious bodily injury, or property damage.

2. Remove the two screws securing the access panel and remove panel.

3. Open the flap of insulation to expose theopening.

4. Reset the high limit by pushing in the red button marked "RESET".

RESET BUTTON

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 the water heater is

"ON".

3. 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.

4. Make certain the disconnect switch, if used, is in the

"ON" position.

5. Check to see the electric service to your house has

not been interrupted. If this is the case, contact the local electric utility.

6. 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 tem- perature shut off system. See "High Temperature Shut Off System" in the "For Your Information" section.

5. Fold the insulation back in place so that it completely covers the thermostat and element.

6. Replace the access panel.

7. Turn "ON" electric power to the water heater.

CAUTION

If the high limit must be reset again, call the Sears Service Center to find out why the high limit turned

"OFF" the electric power.

8. 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.

10. 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.
