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.
1. before beginning, turn "off" electrical power supply to the
water heater.
2. remove the two screws securing the access panel and
remove panel.
3. remove the insulation block to expose the terminal cover.
4. reset the high limit by pushing in the red button marked
"rESET".
5. replace the insulation block so that it is completely covers
the thermostat and element.
6. replace the access panel.
7. Turn "oN" electric power to the water heater.
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.
