In each water heater there is installed at least one anode rod (see
parts section) for corrosion protection of the tank. Certain water
conditions wil! 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 tour
factors which must all be present for the odor to develop:
a a concentration ofsulfate in the supply water.
h 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 he 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
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 problena_
Do not remove the anode leaving the tank unprotected°
doing so, all warranty on the water heater tank is voided.
HYDROGEN GAS: Hydrogen gas can be produced in a
hot water system that has not been used for a long peri-
od of time (generally two weeks or more). Hydrogen gas

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,

HAZARD OF ELECTRICAL SHOCKI Before removing
any access panels or servicing the water heater, make
sure the electrical supply to the water heater is turned
"OFF". Failure to do this could result in DEATH, SERI-
OUS BODILY INJURY,OR PROPERTY DAHAGE.
