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
Draining the Water Heater
!
CAUTION: Shut off gas to the water
heater at the manual gas shut-off valve
before draining water.
!
DANGER: Before manually operating
the temperature and pressure relief
valve, make certain no one will be
exposed to the hot water released by the
valve. The water drained from the tank
may be hot enough to present a scald
hazard and should be directed to a
suitable drain to prevent injury or
damage.
Before turning off the cold water supply to
the water heater, open a hot water faucet
allowing sufficient cold water into the
tank to prevent the risk of a scald injury
while draining the water heater. Once the
water in the tank is no longer hot, turn off
the cold water supply to the water heater.
Open a hot water faucet or lift the handle
on the relief valve to admit air to the tank.
Attach a garden hose to the drain valve on
the water heater and direct the stream of
water to a drain. Open the valve.
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 gas control (thermostat),
burner, relief valve and venting system
should be made by service personnel
qualified in gas appliance repair.
It is suggested that a routine preventative
maintenance program be established and
followed by the user.
Periodically inspect plastic vent pipe.
Make certain that all joints are secure and
that vent pipe supports are all in place.
Check the outdoor vent terminal to see that
it is free of obstructions, and that there is
no damage nearby caused by condensate.
Inspect dilution air inlet and combustion
air inlet openings. Make certain no
blockage exists. Clean any lint, dirt or oil
accumulation that may exist.
Periodically clean the screens in the vent
terminal (if applicable).
At least once a year, lift and release the
lever handle on the temperature pressure
relief valve, located near the top of the
water heater, to make certain the valve
operates freely. Allow few quarts to be
drained through the discharge line to an
open drain.
NOTICE: If the temperature and
pressure relief valve on the water heater
discharges periodically, this may be due
to thermal expansion in a closed water
system. Contact the water supplier or
your plumbing contractor on how to
correct this. DO NOT plug the relief
valve outlet.
A water heater’s tank can act as a settling
basin for solids suspended in the water. It
is therefore not uncommon for hard water
deposits to accumulate in the bottom of the
tank. It is suggested that a few quarts of
water be drained from the water heater’s
tank every month to clean the tank of these
deposits.
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.
The anode rod should be removed from
the water heater’s tank annually for
inspection and replaced when more than 6
in. of core wire is exposed at either end of
the rod.
Make sure the cold water supply is turned
off before removing anode rod.
This water heater incorporates a
combustion shut off device that shuts
the operation of the water heater down
if undesirable combustion conditions
occur, such as the presence of flammable
vapors or blockage of the combustion air
inlet openings. Please contact a Qualified
Service Technician if this occurs.
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.
