STRANGE SOUNDS
Possible noises due to expansion and contraction of some metal
parts during periods of heat-up and cool-down do not represent
naraifiil or dangerous conditions.
Condensation causes sizzling and popping with the burner area
during heating and cooling periods and should be considered
normal. See “Condensation section.
SMELLY WATER
In each glasslincd water heater there is installed at least one
anode rod (see parts section) for corrosion protection of the
tank. Certain water conditions will cause a reaaion between this
rod and the water. The most common complaint associated with
the anode rod is one of a “rotten egg smell”. This odor is derived
from hydrogen suIBde gas dissolved in the water. The smell is
the result of four factors which must all be present for the odor
to develop:
a. a concentration of sulfate in the supply water.
b. little or no dissolved oxygen in the water.
c. a sulfate reducing bacreria within the water heater, ■ (This
harmless bacteria is non-toxic to humans.)
d. an excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.
Smelly water may 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 Sears Service for further information concerning
an Anode Replacement Kit #9001453 and this Chlorination
Treatment.
If the smelly water persists after the anode replacement and chlo­
rination treatment, we can only suggest that continuous chlori­
nation 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 tank is voided.
“AiR” IN HOT WATER FAUCETS
AWARNING
HYDROGEN GAS; Hydrogen gas can be produced in a hot
water system that has not been used for a long period of time
(gener^ly 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 ^cet
be opened for several minutes at the Idtchen sink before any
electrical appliances which are connected to the hot water sys­
tem 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.
