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 of a "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 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 persistsafter 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.

STRANGE SOUNDS
Possible noises due to expansion and contraction of some metal
_arts during periods of heat-up and cool-down do not represent
armful or dangerous conditions.
AWARNING
HYDROGEN GAS:Hydrogengascan be producedin a hot
watersystemthat hasnot beenusedfor a longperiodof time
(generallytwo weeksor more). Hydrogengasis extremely
flammableand explosive.To preventthe possibilityof injury
underthese conditions,we recommend the hot water faucet
be openedfor severalminutesat the kitchensinkbeforeany
electricalapplianceswhichareconnectedto the hot watersys-
tem are used(suchas a dishwasheror washingmachine).If
hydrogengasis present,there will probablybe an unusual
soundsimilarto air escapingthrough the pipeasthe hotwater
faucet isopened.There must be no smokingor open flame
nearthe faucetat the time it isopen.
Condensation causes sizzling and popping with the burner area
during heating and cooling periods and should be considered
normal. See "Condensation" section.
