Care and cleaning of the water heater
Draining the Water Heater
CAUTION: Shut off gas to the water
heater at the gas control (thermostat)
gas cock or manual 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.
Housekeeping
Make sure the flammable vapor sensor is
not blocked or obstructed.
To ensure sufficient ventilation and
combustion air supply, proper clearances
must be maintained.
When installed in a closet, DO NOT
block or obstruct any of the combustion
air inlet openings located around
the perimeter of the water heater. A
minimum of 1” is required between
these combustion air inlet openings and
any obstruction.
DANGER: Combustible
materials, such as clothing,
cleaning materials, or
flammable liquids, etc., must
not be placed against or next
to 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 gas control (thermostat),
burner, relief valve, internal flue-way 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, 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 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. If allowed to accumulate, these
solids can cover the gas control (thermostat)
sensors, causing the sensors to operate
erratically. Because accumulated solids
can prevent the gas control (thermostat)
sensors from accurately reading the water
temperature, the water at the fixture can be
hotter than the gas control (thermostat) dial
setting. 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.
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.
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.
