Care and cleaning of the water heater.
Routine Preventative 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, air
intake, water filter and flue terminal
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. 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 11 of
this manual for instructions on leak
testing.
The cold water supply filter 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.
