1.
Read the "General Safety" section, page 2 of this manu- 3.
al first and then the entire manual carefully. If you don't
follow the safety rules, the water heater will not oper-
ate properly. It could cause DEATH, SERIOUS BODILY
INJURY AND/OR PROPERTY DAMAGE. 4.
This manual contains instructions for the installation,
operation, and maintenance of this electric water
heater. It also contains warnings throughout the manual
that you must read and be aware of. All warnings and
all instructions are essential to the proper operation of
the water heater and your safety. Since we cannot put
everything on the first few pages, READ THIS ENTIRE 5.
MANUAL BEFORE ATTEMPTING TO INSTALL OR
OPERATE THE WATER HEATER.
2,
The installation must conform with the instructions in
this manual; electric company rules; and Local Codes,
or in the absence of Local Codes, with the latest edition
of the National Electrical Code. This publication is
If after reading this manual you have any questions or
do not understand any portion of the instructions, call
Sears Service Center.
Carefully plan the place where you are going to put the
water heater. Correct electrical wiring and connections
are very important in preventing death from possible
electrical shock and fires.
Examine the location to ensure the water heater com-
plies with the "Locating the New Water Heater" section.
For California installation this water heater must be
braced, anchored, or strapped to avoid falling or mov-
ing during an earthquake. See instructions for correct
installation procedures. Instructions may be obtained
from your local dealer, wholesaler, public utilities or
California office of the State Architect, 400 P Street,

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.
Q Check to make the electrical

sup-
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.

NOTE: If using copper tubing, solder tubing to an
adapter before attaching the ad_aptor to the cola water
inlet connection. Do not solder the cold water supply
line directly to the cold water inlet. It will harm the clip
tube and damage the tank.
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.
