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 lter and venting
system should be made by service
personnel qualied 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
ush 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
ammable 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
lters 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.
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: Hotter
water increases the
potential for hot
water scalds.
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.
Care and Cleaning of the Water Heater
Routine Preventative Maintenance
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

on a hot water faucet.

disconnected.
