Venting System Inspection
The water heater’s internal flue must be
inspected periodically to be certain it is
clean by removing the flue damper, draft
hood, and flue baffle.
When reinstalling the flue baffle make
certain it is hung securely by its collar at
the top of the flue way.
Reinstall the flue damper and the draft
hood.
Inspect the gas venting system and/or the
chimney.
Make certain the vent connector from
the draft hood to the vent system and/or
the chimney is properly positioned and
securely attached.
If after inspection of the vent system
you found soot or deterioration;
call the local gas utility to correct the
problem and clean the flue, or replace
the flue baffle, and venting system before
resuming operation of the water heater.
Test for spillage at the draft hood relief
opening after 5 minutes of burner
operation. Use a flame of a match or
candle or smoke. The flame or smoke
should be pulled into the draft hood’s
relief opening(s). If the flame or smoke
is not pulled into the draft hood's relief
openings, shut off the water heater and
make proper adjustments/repairs to the
venting system.
Burner Inspection
Visually inspect the pilot burner and main
burners periodically.
Through the sight glass, inspect the pilot
burner flame with the main burner off and
inspect the main burner while firing.
If any unusual burner operation is noted,
the water heater should be shut off
until qualified service assistance can be
obtained.
CAUTION: For your safety, cleaning
of the burner must be performed only by
qualified service personnel. The burner
chamber is a sealed area. If the burner
access door is removed, the burner access
door gasket must be replaced.
For cleaning, remove the burner from the
water heater. A vacuum cleaner can be
used on the burner and floor shield inside
the water heater. The burner can also be
cleaned by scrubbing with mild detergent.
Proper burner and pilot burner
pattern.
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.
