Care and cleaning of the water heater.
Draining the Water Heater
CAUTION: Shut off gas to the water
heater at the thermostat gas cock or manual
shut-off valve before draining water.
DANGER: Before manually operating the
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.
In order to drain the water heater, turn off
the cold water supply. 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 suggested that a routine
preventative maintenance program be
established and followed by the user.
It is further recommended that a
periodic inspection of the thermostat,
burner, relief valve, internal flue-way and
venting system should be made by
service personnel qualified in gas
appliance repair.
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 several gallons to
flush through the discharge line to an open
drain.
NOTICE: If the temperature and
pressure relief valve on the hot 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
setting 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″ of core wire is exposed at either end of
the rod.
Make sure the cold water supply is turned
off before removing anode rod.
Inspect air inlet assembly beneath mobile
home (if applicable) to make certain flow
of air to the water heater for adequate
combustion (proper burner operation) and
ventilation is not obstructed.
Housekeeping
To insure sufficient ventilation and
combustion air supply, proper clearances
must be maintained.

DANGER: Before
manually operating the relief
valve, make certain no one will
be exposed to the danger of
coming in contact with 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: 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: Combustible
materials, such as clothing,
cleaning materials, or flammable
liquids, etc., must not be placed
against or next to the water
heater.
