"AIR" IN HOT WATER FAUCETS
■ WARNING.
HYDROGEN GAS: Hydrogen gas can be produced in a
hot water system that has not been used for a long peri­
od of time (generally two weeks or more). Hydrogen gas
i< extremely flammable and explosive. To prevent the
possibility of injury under these conditions, we recom­
mend the hot water faucet be opened for several min­
utes at the kitchen sink before any electrical appliances
which are connected to the hot water system 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 is open.
HIGH TEMPERATURE SHUT OFF SYSTEM
This water heater is equipped with an automatic gas shut
off system. 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 control valve must be replaced.
If this were to occur, turn "OFF" the entire gas supply to
the water heater. Contact the Sears Service Center.
-WARNING
Should overheating occur or the gas supply fail to
shut off, turn "OFF" the manual gas control valve to
the appliance.
NOT ENOUGH OR NO HOT WATER
1. Check the manual gas shut off valve to be sure it is open.
2. Check the pilot flame. It may have gone out. All models
have an opening behind the outer door for viewing the
pilot.
3. 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 extreme­
ly 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 control valve must
be replaced. Contact the Sears Service Center.
4. The gas control knob must be turned to the "ON" position.
5. The temperature adjustment dial may be set too low. See
the "Temperature Regulation" section.
6. The gas company can check the gas input to see if it is
correct. An underfired water heater will not heat water as
quickly.
7. Look for leaking or open hot water faucets. Make sure all
are closed.
8. 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.
9. 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 temperature setting.
2. If lower temperature settings will not lower the water
temperature, call the Sears Service Center.
Periodic Maintenance
Venting System Inspection
least once a year a visual inspection should be made of
¡^e venting system. You should look for;
'• Obstructions which could cause improper venting. The
combustion and ventilation air flow must not be
^obstructed.
'■ Parnage or deterioration which could cause improper
venting or leakage of combustion products.
.Rusted flakes around top of water heater.
-WARNING-
gemicai vapor corrosion of the flue and vent system may
‘^cur if air for combustion contains certain chemical vapors.
can propellants, cleaning solvents, refrigerator and air
Wditioner refrigerants, swimming pool chemicals, calcium
sodium chloride, waxes, bleach and process chemicals
typical compounds which are potentially corrosive.
■ WARNING
Obstructions and deteriorated vent systems may pre­
sent serious health risk or asphyxiation.
- WARNING -
Be sure the vent piping is properly connected to pre­
vent escape of dangerous flue gasses which could
cause deadly asphyxiation.
-WARNING
If after inspection of the vent system you found sooting or
deterioration, something is wrong. Call the local gas utility
to correct the problem and clean or replace the flue and
venting before resuming operation of the water heater.
