WATER
IS TOO
HOT
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,
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.
A WARNING
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.
