Safety Precautions

A WARNING

Improper installatton, adjustment, alteration, service or maintenance can cause DEATH, SERIOUS BODILY

INJURY, OR PROPERTY DAMAGE. Refer to this manual for assistance or consult your local Sears Service Center for further information.

A WARNING

At the time of manufacture diis v/ater 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 :md Automatic Gas Shutoff Devices for Hot Water Supply Systems, and the current edition of ANSI Z2I.22 • CSA 4.4 æid the code requirements of ASME. If replaced, the valve must meet the requirements of

local codes, but not less than a combination temperature <md pressure relief valve certified as meeting the requirements for

Relief Valves and Automatic Gas Shutoff Dewces for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4 by a nationally recog

nized te^ng laboratory that maintains periodic inspection of production of listed equipment or materials. The valve must be mariced with a maximum set pressure not to exceed the marked hydrostatic woriting pressure of the water heater (ISO lbs./sq. in.) and a discharge edacity not

less than the water heater input rate as shown on the model

rating plate. (Electric heaters - watts divided by lOOO x 3412 equd BTU/Hr. rate.) Your locid jurisdictional autiiority, while mandating tiie use of a temperatijre-pressure relief valve complying wth ANSI Z21.22 • CSA 4.4 and ASME, may require a vidve model different from the one furnished witii tiie 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 instidied 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’s designated opening or plugged. The temperabjre-pressure relief valve must be instidled directly

into the fitting of the water heater designated for tiie relief valve.

Position the valve downward iuid provide tubing so that any dis charge will exit only within 6 inches <d>ove, or at any distance below the structural floor. Be certain that no contact is made ^h 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 die 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, lb prevent bodily injury, haz ard to life, or ^operty damage, the relief vdve murt be idlowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suititie

means, the water flow may cause prqserty dam<^. 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 disdibution.

• 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 dr^n.

• Must not have æiy v^ve betmen the relief valve æid 1ш1к.

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, SERI OUS BODILY INJURY, OR PROPERTY DAMAGE.

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, 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.

A WARNING

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 can result in DEATH, SERIOUS BODILY

INJURY, OR PROPERTY DAMAGE. If you have any ques tions or doubts consult your electric company.

A WARNING

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 remove operating instructions, and safety

related warning labels and materials affixed to the water heater.

d. DO obtain new warning and instruction labels from

Sears for placement on the jacket directly over the existing labels.

A WARNING

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 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 Store. Such a drain pan must be

piped to an adequate drain.

Removing the Old Water Heater

IKIIIIi

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.

[ 5 If yoti 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 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 disconnected and ready to be removed.

b. If you have galvanized pipe to the

water heater, loosen the two gal

vanized 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

1-,} now completely disconnected and

ready to be removed.

A WARNING

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.

Check again to make sure the electrical supply is turned “OFF” to the water heater. Then unplug the water heater (cord set) or disconnect the electrical sup ply 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 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 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

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.

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.

Optional Wall Mounting

A WARNING

Wail construction at the point of the water heater instal

lation must be capable of supporting at least 200 pounds.

As an example: if the water heater is to be installed on a wall of gypsum board (dry wall) or other material not capable of sup porting the water heater filled with water, additional bracing will be necessary. Iwo possibilities are shown below.

1. Using two sheet metal screws supplied, secure the top mount ing bracket to the top of the water heater.

SECURING SCREWS

2. Using the remaining two sheet metal screws provided, secure the bottom mounting bracket to the bottom of the water heater.

Installation Instructions (cont’d)

Optional Wall Mounting (conty)

3. Determine the location on the wall, and then the height above the floor which the wall securing bracket will be placed. Using adequate screws, or nuts and bolts (not sup plied) , fasten the wall securing bracket to the wall.

’»A WARNING

HOTTER WATER CAN SCALD: Water heaters are intend ed to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish wash

ing, and other sanitizing needs can scald mid 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 temperature water at the hot water tap, then you must take special precautions. In addi tion to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, shall be used at the hot water t^s used by these peo

ple 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 thermostat, read the

“Temperature Regulation” section in this mmiual.

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 must be provided to control thermal expansion. Contact the local utility or Sears Service Center on how to control this situation.

The illustration shows the attachment of the water piping to the water heater. The water heater is equipped with V " water connections.

• Look at the top of the water heater. The hot water outlet is marked hot. Put two or three turns of teflon tape around the threaded end of the compression coupling and around the /i" threads of the

V " x 14" reducer bushing. Put two or three turns of

teflon tape around both ends of a 14" threaded nipple (not sup plied in the installation kit). Attach the 14" threacled nipple to the X 14" reducer bushing and screw into the hot water outlet of the water heater. Using flexible connectors, connect the hot

water pipe to the hot water outlet of the water heater.

NOTE: If using copper tubing, solder tubing to an

adapter before attaching the adapter to the water connec tions. Do not solder the water supply lines directly to the connections of the water heater. It will harm the fittings on the water heater.

• Look at the top 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 compression coupling and around the 14" threads of the 14" x 14" reducer bushing. Put two or three turns of teflon tape around both ends of a 14" threaded nipple (not sup plied in the installation kit). Attach the 14" threaded nipple to the 14" X 14" reducer bushing and screw into the cold water inlet of the water heater. Using flexible connectors, connect the hot

water pipe to the hot water outlet of the water heater.

NOTE: Your 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.
