"AIR" IN HOT WATER FAUCETS

AWARNING

HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet be opened for several minutes at the kitchen sink before any electrical applianceswhich are connected to the hot water sys- tem are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it isopen.

HIGH TEMPERATURE SHUT OFF SYSTEM

This water heater is equipped with an automatic gas shut off sys- tem. The high temperature shut off is built into the gas control valve. This system shuts off the gas supply to the water heater

burners when high water temperatures are present. It is non-

resettable. If the high temperature shut off activates, the gas con- trol valve must be replaced. If this were to occur, turn "OFF" the entire gas supply to the water heater. Contact the Sears Service

Center,

WATER IS TOO HOT

1.The temperature adjustment dial may be set too high. See the "Temperature Adjustment" section.

NOTE: A period of time is necessary after an adjustment has been made for the water temperature to reach the new tem-

perature setting.

2.If lower temperature settings will not lower the water tempera- ture, call the Sears Service Center.

AWARNING

Due to the nature of the typical gas water heater, the water temperature in certain situations may be hotter than the thermostat setting.

Short, frequent draws of hot water - especiallywith very cold incoming water - can shock the thermostat into brief operation resulting in hotter and hotter layers of water closerto the top of the tank.

Changes in hot water usagepatterns or raising the tem- perature differential between the cut-on of the thermo- stat and the cold water temperature will usually eliminate the problem.

AWARNING

Should overheating occur or the gas supply fail to shut off,

turn "OFF" the manual gas contro va ve to the app ance.

NOT ENOUGH OR NO HOT WATER

Check the manual gas shut offvalve to be sure it is open.

Check the pilot flame. It may have gone out. All models have an opening behind the outer door for viewing the pilot.

•If the p'lot s not lit, follow the 'Lighting" instructions in this manual or located above the gas control valve on the water heater to relight the pilot. If the water was extremely hot and is now cold, the high limit safety temperature shut off may have put out the burner and pilot. If the high temperature shut off

activates, the gas controlvalve must be replaced. Contact the Sears Service Center.

•. The gas control knob must be turned to the "ON" position.

•The temperature adjustment dial may be set too low. See the "Temperature Regulation" section.

•The gas company can check the gas input to see if it is correct. An underfired water heater will not heat water as quickly.

•Look for leaking or open hot water faucets. Make sure all are closed.

•The cold water inlet temperature may be colder during the win- ter months. It will take longer to heat the water and seem like less hot water.

•If you cannot find what is wrong, call the Sears Service Center.
