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
[h • ¢¢ , . . .
e anode rod is one of a rotten egg smell . This odor ,s 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
T[eatment.

STRANGE SOUNDS
Possible noises due to expansion and contraction of some metal
Karts during periods of heat-up and cool-down do not represent
armful 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.
lfthe smellywater persists afterthe anodereplacementand chlo-
rination treatment, we can only suggest that continuous chlori-
nation and filtering conditioning equipment be considered to
eliminate the water problem.
Do not removethe anode leaving the tank unprotected. By
doing so, allwarranty on the water heatertank is voided.
"AIR" IN HOT WATER FAUCETS
AWARNING
HYDROGEN GAS: Hydrogengascan be producedin a be4
water systemthat hasnot beenused_r a longperiod of tirm
(generally two weeks or more). Hydrogen gasis extremel_
flammable and explosive.To prevent the possibilityof injur_
under these conditions,we recommendthe hot water fauce
be openedfor severalminutesat the kitchensinkbefore any
electricalapplianceswhichare connectedto the hot water sys-
tem are used(such as a dishwasheror washing machine).If
hydrogengas is present, there will probably be an unusual
soundsimilarto air escapingthrough the pipeasthe hotwater
faucet isopened. There must be no smoking or open flame
nearthe faucetat the time it isopen.
