Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater tank is voided.
"AIR" IN HOT WATER FAUCETS
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
fl ammable 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 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 fl ame near
the faucet at the time it is open.
RUMBLING NOISE
In some water areas, scale or mineral deposits will build up on
your heating elements. This buildup will cause a rumbling noise.
Follow Element Cleaning/Replacement instructions to clean and
replace the elements.
HIGH TEMPERATURE SHUT OFF SYSTEM
The water heater has a high limit shut off system with a reset
button located on the thermostat.
Follow the resetting instructions which refer to the high limit
behind the access panel.
1. Before beginning, turn "OFF" electrical power supply to the
water heater.
FIGURE 33.
2. Remove the screw securing the access panel, then remove
the panel.
3. Fold the insulation back to expose the thermostat.
4. Reset the high limit by pushing in the red button marked
"RESET".
5. Replace the insulation so that it completely covers the
thermostat and element.
6. Replace the access panel.
7. Turn "ON" electric power to the water heater.
If the high limit must be reset again, call Sears Service Department
to fi nd out why the high limit turned "OFF" the electric power
NOT ENOUGH OR NO HOT WATER
1.
In a new installation, the water heater may not be properly
connected. Make sure the cold water supply valve is open.
Review and check piping installation. Make sure that the
cold water line is connected to the cold water inlet to the
water heater and the hot water line to the hot water outlet
on the water heater.
2.
Make sure the electrical supply to your water heater is "ON".
3.
Check for loose or blown fuses in your water heater circuit.
Circuit breakers weaken with age and may not handle their
rated load and should be replaced.
4.
Make certain the disconnect switch, if used, is in the "ON"
position.
5.
Check to see the electric service to your house has not been
interrupted. If this is the case, contact the electric company.
6.
Is the thermostat set to the desired temperature? See
Temperature Regulation section.
7.
If you had experienced very hot water and now no hot water,
the problem may be due to the high temperature shut off
system. See High Temperature Shut Off System in the
Troubleshooting section.
8.
During very cold weather, the incoming water will also be
colder and it will require a longer time to become heated.
9.
The hot water usage may exceed the capacity of the water
heater. If so, wait for water heater to recover after abnormal
demand. Also examine pipes and faucets for possible water
leaks.
10. If you can not determine the problem, then call the Sears
Service Department.
WATER IS TOO HOT
Adjust the thermostat to a lower setting. See the Temperature
Regulation section.
