Care and cleaning of the water heater.
Draining the Water Heater
CAUTION: Shut off power to the
water heater before draining water.
DANGER: Before manually operating
the 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.
Vacation and Extended Shutdown
NOTE: Refer to the Hydrogen Gas Caution
in the Operating Instructions.
Routine Preventive Maintenance
DANGER: Before manually operating
the relief valve, make certain no one will be
exposed to the danger of coming in contact with
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.
NOTE: 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.
