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.
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 water heater
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 14
of this manual for instructions on leak
testing.
The air intake and cold water supply
filters should be cleaned monthly. Refer
to the "Housekeeping" section for
further information.

you feel something is wrong with the
unit.
DO NOT allow children to operate or
otherwise handle the unit.
