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
rod and the water, The most common complaint associated with
the anode rod is one ofa _rotten egg smell". This odor is derived
from hydrogen sulfide 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 bacteria within the water heater. (This
harmless bacteria]s 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 f_rther information
concerning
an Anode Replacement Kit #9001453
and this Chlorination

If the smeUywater persists afterthe anode replacement and chlo-
rination treatment, we can only suggest that continuous chlori-
nation and filtering conditioning equipment be considered to
eliminate the waterproblem.
Do not remove the anode leaving the rank unprotected. By
doing so, all warranty on the water heater tank is voided.

Possible noises due to expansion and contraction of some metal

I HYDROGEN GAS: Hydrogen gas can be produced in a hot

flammable and explosive.To prevent the possibilityof injury
under these conditions,we recommend the hot water faucet
be opened for severalminutes at the kitchen sink before any
electricalappliances whichare connectedto the hot water sy_
tern are used (suchas a dishwasher or washing machine). If
hydrogen gas is present, there will probably be an unusual
