Operational Conditions
HIGH TEMPERATURE SHUT OFF SYSTEM
SMELLY WATER
The water heater has a high limit shut off system with a reset
button located on the thermostat.
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 complaint 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 concentration of sulfate in the supply water,
• litde or no dissolved oxygen in the water.
• a sulfate reducing bacteria within the water heater. (This
harmless bacteria is non-toxic to humans.)
• 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 ehJorinating 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.
Do. not remove the anode leaving the tank unprotected. By
domg so, all warranty on the water heater tank is voided.
Follow the resetting instructions which refer to the high limit
behind the access panel.
• Before beginning, turn "OFF" electrical power supply to the
water heater.
A WARNING
HAZARD OF ELECTRICAL SHOCK! Before
removing any access panels or servicing the water
heater, make sure the electrical supply is turned
"OFF" to the water heater• Failure to do this could
result in DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE•
"AIR" IN HOT WATER FAUCETS
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in
a hot water system that has not been used for a long
)eriod of time (generally two weeks or more)•
Hydrogen gas is extremely flammable and explosive.
To prevent the possibility of injury under these condi-
tions, 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 present, 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 isopen.
• Remove the two screws securing the access panel and remove
panel.
• Open the flap of insulation to expose the opening.
• Reset the high limit by pushing in the red button
marked _RESET'.

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.
• Fold the insulation back in place so that it completely covers
the thermostat and element.
• Replace the access panel.
• Turn _ON" electric power to the water heater.
