INSTALLED IN SUITABLE AREA: To insure sufficient ventilation and combustion air supply, proper clearances from the water heater must be maintained. See “Locating the New Water Heater” section. Combustible materials such as clothing, cleaning materials, or flammable liquids, etc. must not be placed against or adjacent to the water heater which can cause a fire.

ANODE ROD INSPECTION

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.

Anode deterioration depends on 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 a qualified technician, and at a minimum should be checked annually after the warranty period.

TEMPERATURE-PRESSURE

RELIEF VALVE OPERATION

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.

If the temperature-pressure relief valve on the appliance weeps or discharges periodically, this may be due to thermal expansion. You may have a check valve installed in the water line or a water meter with a check valve. Consult your local water supplier or service agency for further information. Do not plug the temperature- pressure relief valve.

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.Set the blower switch 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 terminate to an adequate drain.

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

FIGURE 22.

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 discharge will not cause any property damage, as the water may be extremely hot, see Figure 22.

If after manually operating the valve, it fails to completely reset and 25

6.CLOSE the drain valve.

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

8.Follow the lighting instructions on the label or see page 14 under “Lighting Instructions” to restart the water heater.

DRAIN VALVE WASHER REPLACEMENT

(See Figure 23)

1.Turn “OFF” gas supply to water heater.

2.Follow “Draining” instructions.

3.Turning counterclockwise ( ), remove the hex cap below the screw handle.

4.Remove the washer and put the new one in place.

5.Screw the handle and cap assembly back into the drain valve and retighten using a wrench. DO NOT OVER TIGHTEN.

6.Follow instructions in the “Filling The Water Heater” section.

7.Check for leaks.
