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. !

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.
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. Make certain no
blockage exists. Clean any lint, dirt or oil
accumulation that may exist.
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 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: 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.
