Care and cleaning of the water heater:

Routine Preventive Maintenance

Properly maintained, your water heater
will provide years of dependable trouble-
free service. 

It is recommended that a periodic
inspection of the burner, relief valve,
water filter, and venting system should be
made by service personnel qualified in gas
appliance repair.

It is suggested that a routine preventive
maintenance program be established and
followed by the user.

At least once a year, lift and release the
lever handle on the pressure relief valve,
located in the hot outlet piping of the
water heater, to make certain the valve
operates freely. Allow several gallons to
flush through the discharge line to an open
drain.

NOTICE: If the pressure relief valve on
the hot water heater discharges
periodically, this may be due to a
problem in the water system. Contact
the water supplier or your plumbing
contractor on how to correct this
problem.  DO NOT plug the relief valve
outlet.

Rapid closing of faucets or solenoid
valves in automatic water using appliances
can cause a banging noise heard in a water
pipe. Strategically located risers in the
water pipe system or water hammer
arresting devices can be used to minimize

the problem.

Inspect the area around the water heater to
ensure a safe operating environment. Keep
appliance area clear and free from
combustible materials, gasoline, and other
flammable vapors and liquids.

Ensure the unit has not been damaged. If
damage or denting is present, contact a
service personnel to verify proper
operation.

Check for any abnormal sounds during
normal operation of the water heater.

All piping should be checked for gas
and/or water leaks. Refer to page 19 of
this manual for instructions on leak
testing.

The water filter on the cold water supply
fittings should be cleaned monthly. Refer
to the “Housekeeping” section for further
information.

DO NOT

operate the water heater if you

feel something is wrong with the unit.

DO NOT

allow children to operate or

otherwise handle the unit.

Notice:

After inspection, maintenance,

and/or cleaning, ensure proper operation
by turning on a hot water faucet.

Housekeeping

Before performing Housekeeping tasks to
this water heater, turn the unit off and
disconnect the power supply.

Vacuum around the water heater for dust,
dirt and lint on a regular basis. 

Clean the water heater and remote control
by using a damp soft cloth with a few
drops of mild detergent and gently wiping
the surfaces of the unit. Wipe any
remaining moisture with a dry soft cloth.

To ensure sufficient ventilation, proper
clearances must be maintained. 

DO NOT block or obstruct the air intake
opening on the termination.  A minimum of
12” (30 cm) is required between this
combustion air inlet opening and any
obstruction.

The water filter should be cleaned on a
monthly basis.

HOW TO CLEAN THE WATER FILTER:

l

Make sure the unit is OFF and the

electrical power supply has been

disconnected.

l

Turn the water supply OFF to the

heater.

l

Drain heater.  See “Draining The
Water Heater” section on page 31.

l

Unscrew the water filter, and slide the

filter out.

l

DO NOT

tap the filter as it may

deform and/or damage the filter.

l

To remove severe sediment and dirt,

use a soft brush and wash with running

water.

l

Return the filter to the water heater and
screw in the filter.

l

Turn the electrical power supply and
cold water supply ON to the water
heater.

DANGER: Before

manually operating the
relief valve, make certain
no one will be exposed to
the danger of the hot water
released by the valve. The
water may be hot enough to
create a scald hazard. The
water should be released
into a suitable drain to
prevent injury or property
damage.

DANGER: Combustible

materials, such as clothing,
cleaning materials, or
flammable liquids, etc., must
not be placed against or next
to the water heater.

!

DANGER:  Failure to

perform the recommended
Routine Preventative
Maintenance can harm the
proper operation of this
water heater, which can
cause carbon monoxide
dangers, excessive
hot water temperatures and
other potentially hazardous
conditions.

DANGER: Hotter water

increases the potential for
Hot Water Scalds.

!

DANGER: Shock Hazard

Make sure the electrical
power to the water heater is
off to avoid potential serious
injury or damage to
components.
