HIGH TEMPERATURE SHUT OFF SYSTEM
This water heater is equipped with an automatic gas shut offsys- tern. The high temperature shut offis 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, tf 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
•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.
•If lower temperature settings will not lower the water tempera- ture, call the Sears Service Center.

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 pilot is not lit, follow the "Lighting" instructions in this manual are located above the gas control valve on the water heater to relight thepilot. If the water was extremely hot and is now cold, the high rJmit 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.
iAn 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
winter 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.

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 - especially with very ¢old incoming water - can shock the thermostat into brief operation resulting in hotter and hotter layers of water closer to the top of the tank.
Changes in hot water usage patterns or raising the tom- perature differential between the
