HIGH TEMPERATURE SHUT OFF SYSTEM WATER IS TOO HOT
This water heater is equipped with an automatic gas shut offsys-
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-
resetrable. 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.
I . _,WARNING
Should overheatingoccur or the gassupplyfail to shut off,
turn "OFF" the manual gascontrol valveto the appli_, ce.
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 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 Regulat'on" section.
• The gas company can check the gas input to see if it is correct.
An underflred 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.
• 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
temperature setting.
• If lower temperature settings will not lower the water tempera-
ture, call the Sears Service Center.
_,WARNING
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
coldincoming water - can shockthe thermostat into brief
operation resulting in hotter and hotter layers of water
closerto the top of the tank.
Changes in hot water usage patterns or raising the tem-
perature differential between the cut-on of the thermo-
stat and the cold water temperature will usuallyeliminate
the problem.
• If you cannot find what is wrong, call the Sears Service Center.
