Extended Shut-Down - Rheem PowerVent Series Use & Care Manual

NOTICE: Refer to the
Hydrogen Gas Caution in
the Operating Instructions.
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.
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.
