Care and cleaning of the water heater.
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.
