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.

DANGER:
Combustible
materials, such as clothing,
cleaning materials, or
flammable liquids, etc.,
must not be placed against
or next to the water heater.
!
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.
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

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 setling
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.
