SMELLY WATER
In each glasslined 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 reaction between this
rodand the water. The most common complaint assodated with
the anode rod is one of a rotten egg smell. This odor is derived
from hydrogen sulfide gas dissolved in the water. The smell is
the result offuur factors which must all be present for the odor
to develop:
a. aconcentration of sulfate in the supply warer.
b. little or no dissolved oxygen in the water.
c. a sulfate reducing bacteria 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 lessactive 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.
lfthe smelly water persists after the anode replacement and chlo-
rinationtreatment, we can only suggest that continuous chlori-
nation and filtering conditioning equipment be considered to
eliminate the water pmblem.
Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater tank is voided.

STRANGE SOUNDS
Possible noises due to expansion and contraction of some metal
parts during periods of heat-up and cool-down do not represent
harmful or dangerous conditions.
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot
water system that hasnot been used for a long period of time
(generally two weeks or more). Hydrogen gas is extremely
flammable and explosive. To prevent the possibilityof injury
under these conditions, we recommend the hot water faucet
be opened for several minutes at the kitchen sink before any
electrical applianceswhich are connected to the hot water sys-
tem are used (such as a dishwasher or washing machine). If
hydrogengasispresent, there will probablybe an unusual
soundsimilarto air escapingthrough the pipeasthe hotwater
faucet is opened. There must be no smoking or open flame
near the lancet at the time it isopen.
Condensation causes sizzling and popping with the burner area
during heating and coolin_ periods and should be considered
normal. See "Condensation section.
