Anode Rod Inspection

Property Damage Hazard

•Avoid water heater damage.

•Inspection and replacement of anode as needed.

The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water's taste or color. The rod must be maintained to keep the tank in operating condition.

RELIEF VALVE

DISCHARGE PIPE

FIGURE 28B.

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 draining instructions, and replace the temperature-pressure relief valve with a new one.

Failure to install and maintain a new properly listed temperature- pressure relief valve wilt release the manufacturer from any claim which might result from excessive temperature or pressure.

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 your local Sears Service Center for further information. Do not plug the temperature-pressure relief valve.

Draining and Flushing

FIGURE 28A.

Anode deterioration depends on the water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/ or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by calling Sears Service Center. At a minimum the anode(s) should be checked annually after the warranty period.

Temperature-Pressure Relief Valve Operation

The temperature-pressure relief valve must be manually operated at least once a year.

•Hotwater discharge.

•Keep hands clear of drain valve discharge.

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 wilt not cause any property damage or bodily injury. The water may be extremely hot.

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.

•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 bodily injury, or property damage.

1.Before beginning, turn "OFF" the electric power supply to the water heater.

2.Open a nearby hot water faucet until the water is no longer hot.

3.Close the cold water inlet valve.

4.Connect a hose to the drain valve and terminate it to an adequate drain or external to the building.

5.Open the water heater drain valve and allow all of the water to drain from the tank. Flush the tank with water as needed to remove sediment.
