D. An excess of active hydrogen in the tank. This is caused by
corrosion protective action of the anode.
Smelly water may be eliminated or reduced in some water
heater models by replacing the anode rod (s) with one of less
active material, and then chlorinating the water heater tank and
all hot water lines. Contact the local Sears Service Center for
further information concerning an Anode Replacement Kit
#9001453 and this Chlorination Treatment. Anode replacement
and chlorination of the tank are not covered by the water
heater’s limited warranty.
If the smelly water persists after the anode replacement and
chlorination treatment; then you should consider chlorinating
or aerating your water supply.
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
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 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.
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.
NOTE: If your water heater is connected to an “Off Peak” Clock,
and uses the “3 wire lead” wiring diagram in the “Wiring
Diagram” section, then the water heater will have a high limit
on both the upper and lower thermostats. Follow the instructions
to reset the high-limit behind the upper and lower access panels.
1. Before beginning, turn “OFF” electrical power supply to the
water heater.
FIGURE 44.
2. Remove the two screws securing the access panel and
remove panel.
3. Remove the insulation cap with handle.
4. Reset the high limit by pushing in the red button marked
“RESET”.
FIGURE 45.
5. Replace the insulation cap with handle 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 find 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.
