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.
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.
Housekeeping
Visually inspect pilot burner and
relight if necessary.
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.
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 combination 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.
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 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 combination gas
control (thermostat) sensors, causing the
sensors to operate erratically. Because
accumulated solids can prevent the
combination gas control (thermostat)
sensors from accurately reading the water
temperature, the water
at the fixture can be hotter than the
combination 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: Combustible
materials, such as clothing,
cleaning materials, or
flammable liquids, etc., must
not be placed against or next
to the water heater.
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.
