Periodic Maintenance (cont’d)
Service
If a condition persists or you are uncertain about the oper-
ation of the water heater, let a qualified person check it out.
Call the local utility and/or plumbing contractor.
Draining
The water heater should be drained if being shut down dur-
ing freezing temperatures. Also periodic draining and clean-
ing of sediment from the tank may be necessary.
1. Turn the gas control knob to the “OFF” position.
2. CLOSE the cold water inlet valve to the water heater.
3. OPEN a nearby hot water faucet and leave open to
allow for draining.
4. Connect a hose to the drain valve and terminate to an
adequate drain.
5. OPEN the water heater drain valve to allow for tank
draining.
NOTE: If the water heater is going to be shut down and
drained for an extended period, the drain valve should
be left open with hose connected allowing water to ter-
minate to an adequate drain.
6. Close the drain valve.
7. Follow instructions in the “Filling The Water Heater”
section.
8. Follow the operating instructions in the “Operation” sec-
tion to restart the water heater.
Failure to install and maintain a new properly listed temperature-
pressure relief valve will release the manufacturer from any claim
which might result from excessive temperature or pressure.
Temperature-Pressure Relief
Valve Operation
The temperature-pressure relief valve must be manually
operated at least once a year.

Housekeeping
Vacuum around base of water heater for dust, dirt, and lint
on a regular basis.
Oiling Instructions
Oil Fasco motor only every 12 months with 6 drops of SAE
20 motor oil.
WARNING
INSTALLED IN SUITABLE AREA: To insure sufficient venti-
lation and combustion air supply, proper clearances from the
water heater must be maintained. See “Locating the New
Water Heater” section. Combustible materials such as cloth-
ing, cleaning materials, or flammable liquids, etc. must not
be placed against or adjacent to the water heater which can
cause a fire.
WARNING
When checking the temperature-pressure relief valve
operation, make sure that (1) no one is in front of or
around the outlet of the temperature-pressure relief valve
discharge line, and (2) that the water manually discharged
will not cause any property damage because the water
may be extremely hot.
If after manually operating the valve, it fails to complete-
ly reset and continues to release water, immediately close
the cold water inlet to the water heater, follow the drain-
ing instructions, and replace the temperature-pressure
relief valve with a new one.
WARNING
If the temperature-pressure relief valve on the appliance
weeps or discharges periodically, this may be due to
thermal expansion. Your water heater may have a check
valve installed in the water line or a water meter with a
check valve. Consult the water supplier and/or plumb-
ing contractor for further information. Do not plug the
temperature-pressure relief valve.
