Kenmore 334 Housekeeping, Temperature=Pressure Relief Valve Operation, Draining, DISCHARGEPiPE

Housekeeping

Vacuum around base of water heater for dust, dirt, and lint on a regular basis.

Temperature=Pressure Relief Valve Operation

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

• Burn hazard

Fire and Explosion Hazard

•Do not obstruct combustion air openings at the bottom of the water heater.

Do not use or store flammable

vapor products such as gasoline,

solvents or adhesives in the same room or area near water heater or other appliance.

Visibly inspect air intake screen at least once every six months and clean if accumulated lint.

•Can cause serious injury or death.

INSTALLED IN SUITABLE AREA: To insure sufficient ventilation

and combustion air supply, proper clearances from the water

heater must be maintained. See Facts to Consider About the

Location section. Combustible materials such as clothing,

cleaning materials, or flammable liquids, etc. must not be

placed against or adjacent to the water heater because they could catch on fire.

Anode Rod Inspection

Property Damage Hazard

• Avoid water heater damage.

-Inspectionand replacement of anode rod required.

The anode rod is used to protect the tank from corrosion. Most

hot water tanks are equipped with an anode rod. The

submerged rod deteriorates 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 calling the Sears Service Center for an authorized contractor. At a minimum, the anode(s) should be checked annually after the warranty period.

. Hot water discharge.

• Keep clear of relief valve discharge outlet.

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 24.

FIGURE 24.

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.

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 the Sears

Service Center for further information. Do not plug the

temperature-pressure relief valve.

Draining

,,Burn hazard

•Hotwater discharge.

•Keep hands clear of drain valve discharge.

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. Turn the gas control knob to the "OFF" position.
