Care and Cleaning of the Water Heater
NOTICE: Refer to the
Hydrogen Gas Caution in
the Operating Instructions
NOTICE: Do not remove
the anode rod from the
water heater's tank.
Operation with the anode

shorten the life of the glass
lined tank and will exclude
warranty coverage.

Vacation and Extended Shut-Down
If the water heater is to remain idle for
an extended period of time, the power
. and water to the appliance should
be turned off to conserve energy
and prevent a build-up of dangerous
hydrogen gas.
The water heater and piping should be
drained if they might be subjected to
freezing temperatures.
Anode Rod
This water heater is equipped with
an anode rod designed to prolong
the life of the glass-lined tank. The
anode rod is slowly consumed, thereby
eliminating or minimizing corrosion of
the glass-lined tank.
After a long shut-down period, the
water heater's operation and controls
should be checked by qualified service
personnel. Make certain the water
heater is completely filled again before
placing it in operation.
Water sometimes contains a high
sulfate and/or mineral content and
together with cathodic protection
process can produce a hydrogen
sulfide, or rotten egg odor in the
heated water. Chlorination of the water
supply should minimize the problem.
