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.
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.
NOTICE: Refer to the
Hydrogen Gas Caution in the
Operating Instructions.
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.
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.
NOTICE: Do not remove
the anode rod from the water
heater’s tank, except for
inspection and/or replacement,
as operation with the anode
rod removed will greatly
shorten the life of the glass
lined tank and will exclude
warranty coverage.
