Installation Instructions
Removing the Old Water
Heater
Turn "OFF" electrical supply to the water heater.
Turn "OFF" the water supply to the
water heater at the water shutoffvalve or
water meter.
If you have copper piping to the water
a.
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 amid 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 ready to be removed.
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.
A WARNING 1
The water passingo_alve may be extreme- I
ly hot. To avoidbeing scalded, mal_. sure all connectionsJ
are tight and that the water flow msdirected away from
anyperson, j
Q Check make sure the electrical supply isagain ,to
turned OFF to the water heater. Then disconnect
the electrical supply connection from the water
heater junction box.
If have to the
Qb. you galvanized pipe 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.
ACAUTION ]

Installation Instructions (cont'd)
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.
A CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplished in sucha manner
that if the tank or any connectionsshouldleak, the flowof
water will not causedamage to the structure. When such
locationscannot he avoided,a suitable drain pan should
be installed under the water heater. Drain pansare avail-
able at your localSears stores. Such a drain pan must be
piped to an adequate drain. Under no circumstances is
the manufacturer or Searsto be held liable for any water
damagein connectionwith this water heater.
The Upper Element (if a double element model), is a conven-
tional 3800 watt el.ement 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 conversionto 5500 watts, check the
(I) power supply...mustbe 240 volts,(2) wiring...10gauge
AWG @ type T.W. 60c or equivalent, and (3) Circuit
breakersor 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.
A CAUTION J
INSTALLATION IN RESIDENTIAL GARAGES." TheJ
water heater must be located and/or protected so it is
not subjectto physicaldamage by a mov ng veh c 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 he ma_ked. Using a hardpoint ink
pen, check the appropriate block within the model rating
plate, which is located adjacent to the lower access panel.

_WARNING
HOTTER WATER CAN SCALD: Water heaters are
intendedto produce hot water. Water heated to a tem-
perature which will satisfyspaceheating, clotheswashing,
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 eldedy, children, the infirm, or
physically/mentally handicapped. If anyone using hot
water in your home fits into one of these groups or if
there isa local code or state law requiring a certain tem-
perature water at the hot water tap, then you must take
specialprecautions. In addition to usingthe lowestpossi-
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 valvesare available at plumbingsupplyor
hardware stores. Follow manufacturers instructions for
installationof the valves.Before changingthe factory set-
ting on the thermostat, read the "Temperature
Regulation"sectionin this manual.
The illustration shows the attachment of the water piping to the
water heater. The water heater is equipped with ¾ 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.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the cold water inlet connec-
tion. Do not solder the cold water supply line directly to the
cold water inlet. It will harm the dip tube and damage the
tank.
