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-
resettablc. 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.
AWARNiNG
Should overheating occur or the gas supply fail to shut off,
turn “OFF” the manual gas control valve to the appliance.
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
cold 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 tìie tem­
perature differential between the cut-on of the thermo­
stat and the cold water temperature will usually eliminate
the problem.
_______________
NOT ENOUGH OR NO HOT WATER
• Check the manual gas shut off valve 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 or located above the gas control valve on the water
heater to relight the phot. If the water was extremely hot and
is now cold, the high limit safety temperature shut off may
have put our the burner and pilot. If the high temperature
shut off activates, the gas control valve must be replaced.
Contact the Seats 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
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.
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.
