The temperature-pressure relief valve must be manually

operated at least once a year.

TEMPERATURE-PRESSURE

RELIEF VALVE

DISCHARGE PIPE

Failure to install and maintain a new properly listed tem-

perature-pressure relief valve will release the manufactur-

er from any claim which might result from excessive tem-

perature or pressure.

Draining

The water heater should be drained if being shut down

during freezing temperatures. Also periodic draining and

cleaning of sediment from the tank may be necessary.

1. Before beginning turn “OFF” the electric power supply

to the water heater.

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 or outdoors.

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 terminate to an adequate drain.

6. Close the drain valve.

7. Follow “Filling the Water Heater” instructions in the

“Installing the New Water Heater” section.

8. Turn “ON” power to the water heater.

WARNING

HAZARD OF ELECTRICAL SHOCK! Before removing any

access panels or servicing the water heater, make sure the

electrical supply to the water heater is turned “OFF”.

Failure to do this could result in DEATH, SERIOUS BODI-

LY INJURY, OR PROPERTY DAMAGE.

WARNING

If the temperature-pressure relief valve on the appliance

weeps or discharges periodically, this may be due to ther-

mal expansion. The water heater may have a check valve

installed in the water line or a water meter with a check

valve. Consult a local plumbing contractor and/or the

local water utility for further information. Do not plug the

temperature-pressure relief valve.

WARNING

The temperature-pressure relief valve must be manually

operated at least once a year. Caution should be taken to

ensure that (1) no one is in front of or around the outlet of

the temperature-pressure relief valve discharge line, and

(2) the water manually discharged will not cause any

property damage or bodily injury. The water may be

extremely hot.

If after manually operating the valve, it fails to completely

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.
