Care And Cleaning; Draining The Water Heater; Routine Preventative Maintenance - Rheem GG50T06PVT Use And Care Manual

Care and cleaning of the water heater.
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.

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.

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 and combustion
air inlet openings. 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.
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.
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.
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) 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.
