HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a temperature which will satisfyspaceheating, clothes washing,
dish washing, and other sanitlzmg needs can scald and
permanently injure you upon contact. Some people are
more likely to be permanently injured by hot wafer 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
specmi precautions, in addition 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 taps used by these people or at the water
heater. Mixing valvesare available at plumbing supply or
hardware stores. Follow manufacturers instructions for
insta/latlon of the valves. Before changingthe factory setting on the thermostat,

If you have copper piping to the water
heater, the two copper water pipes can be
cut with a hacksaw approximatdy 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-ptessure 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.

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

Facts to Consider About the
Location
Facts to Consider About The
Convertible Lower Element
You should carefully choose an indoor location for the new
water heater, because the placement is a very important consideration 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.
The Upper Element (if a double element model), is a conventional 3800 watt element which only operates at its rated
wattage on 240 volts. (See rating plate on water heater).
Whether
replacing
an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
Read and follow water heater warnings and instructions. If after
reading these instructions in this manual, if you do not understand any portion, call Sears Service Center.
• 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.
AWARNING
Before making the conversion to 5500 watt.s, check the
(I) power supply...must be 240 volts, (2) wwmg...10 .gang.e
AWG, Type TW, 60°C or equivalent, and (3) Ctrcutt
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.
_CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplishedin sucha manner
that if the tank or any connectionsshouldleak, the flow of
water will not causedamage 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 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.
A CAUTION
.
The Lower Element of the water heater can be converted from
operation at 3800 watts to 5500 watts on a 240 volt system.
I
INSTALLATION
IN RESIDENTIAL
GARAGES. The I
water heater must be located and/or protected so it is
not subject to physicaldamage by a moving vehic e.
" The location selection must provide adequate dearances for
servicing and proper operation of the water heater.
NOTE: Whether or not the element conversion is made the
model rating plate must be marked. Using a hardpoint ink
pen, check the appropriate block within the model rating
plate, which is located adjacent to the lower access panel.

Water supply systems may, because of such events as high line
pressure, f_equent cut-offs, the effects of water hemmer 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 system to be closed. As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water.

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 your water heater is
"ON".
•
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.
Make certain the disconnect switch, if used, is in the "ON"
position.
Check to see the electric service to your house has not been
interrupted. If this is the case, contact the electric company.
•
Are the thermostats set to the desired temperature?
"Temperature Regulation" section.
•
If you had experienced very hot water and now no hot
water, the problem may be due to the high temperature shut
off system. See _High Temperature Shut Off System" in the
Troubleshooting Guide section.
•
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.
•
If you can not determine the problem, then call the Sears
Service Department.
