SMELLY WATER
HIGH
TEMPERATURE
SHUT
OFF SYSTEM
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
com_0,l, aint associated 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 informa-
tion concerning
an Anode Replacement
Kit #9001453
and this
Chlorination
Treatment.
If the smelly water persists after the anode replacement
and chlo-
rination
treatment,
we can only suggest that continuous
chlori-
nation
and filtering
conditioning
equipment
be considered
to
eliminate
the water problem.
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.
NOTE:
If your water heater is connected
to an "OFF PEAK"
clock,
and uses the "3 wire lead"
wiring
diagram
in the
"Wh-ing
Diagram" section,
then the waterheater
will have a
hi-limit
on both the upper and lower thermostats.
Follow
the instructions
to reset the hi-limlt
behind
the upper
and
lower access panels.
• Before beginning, turn "OFF" electrical power supply to the
water heater.

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
akWARNING
HYDROGEN GAS: Hydrogen gas can be produced in a
hot water system that has not been used for a long period
of time (generally two weeks or more). Hydrogen gas is
extremely flammable and explosive.To prevent the possi-
bility of injury under these conditions,we recommend the
hot water faucet be opened for several minutes 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 pre-
sent, 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.
AWARNING
]
HAZARD OF ELECTRICAL SHOCKI Before removing[
any access panels or servicing the water heater, make I
sure the electrical supply to the water.heater is turned I
"OFF". Failure to do this could result m DEATH, SERI-
OUS BODILY INJURY,OR PROPERTY DAMAGE.
• Remove the two screws securing the access panel and remove
panel.
• Remove the insulation block to expose the opening.
• Reset the high limit by pushing in the red button marked
"RESET".

• Replace the access panel.
• Turn "ON" electric power to the water heater.
