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 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.
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 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:
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.
