Care and Cleaning of the Water Heater
Housekeeping
Make sure the Flammable Vapour Sensor
is not blocked or obstructed.
DO NOT expose the Flammable Vapour
Sensor to water, solvents or cleaning
agent
s.
!
DANGER:
Combustible materials,
such as clothing, cleaning
materials, or flammable
liquids, etc., must not be
placed against or next to
the water heater.
Combustion Air-Inlet and Vent System Inspection
Inspect the combustion air-inlet and vent
systems. Make certain that all joints are
secure and that combustion air-inlet and
vent system supports are all in place.
Check the outdoor combustion air-inlet and
vent system terminals to see that they are
free of obstructions, and that there is no
damage nearby caused by condensate.
Burner Inspection
Through the sight glass, visually inspect
the hot surface ignitor and main burner
periodically.
Inspect the hot surface ignitor 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, as it
involves the disconnection of gas piping
and leak testing. The burner chamber is
a sealed area. If the burner access door
is removed, the burner access door gas-
ket 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.

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 com-
pletely 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.
