D. An excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.
Smelly water nay be eliminated or reduced in some water heater
models by replacing the anode(s) with one of less active
material, and then chlorinating the water heater tank and all
hot water lines. Contact the local water heater supplier for
further information concerning an Anode Replacement Kit
#9000029 and this Chlorination Treatment.
If the smelly water persists after the anode replacement and
chlorination treatment, we can only suggest that continuous
chlorination and filtering conditioning equipment be considered
to eliminate the water problem.
Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater 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.
• Before beginning, turn "OFF" electrical power supply to the
water heater.
WARNING
HAZARD OF ELECTRICAL SHOCK! Before removing any
access panels or servicing the water heater, make sure the
electrical supply to the water heater is turned "OFF". Failure to
do this could result in DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
2. Remove the two screws securing the access panel and
remove panel.
3. Remove the insulation block and pad.
4. Reset the high limit by pushing in the red button marked
"RESET".
5. Replace the insulation block and pad 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 a serviceman to find
out why the high limit turned "OFF" the electric power.
NOT ENOUGH OR NO HOT WATER
• 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.
• Make sure the electrical supply to your water heater is "ON".
• 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.
• Make certain the disconnect switch, if used, is in the "ON"
position.
• Check to see the electric service to your house has not
been interrupted. If this is the case, contact the electric utility.
• Are the thermostats set to the desired temperature? See
"Temperature Regulation" section.
• 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
"Operational Conditions" section.
