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.

lfthe smelly water persists afterthe anode replacement and chlo- rination treatment, we can only suggest that continuous chlori- nation and filtering conditioning equipment be cor_sidered 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

AWARNING

HYDROGEN GAS: Hydrogengas can be produced in a hot water systemthat hasnot been usedfor a long peried oftime

(generallytwo weeks or more). Hydrogen gas is ext_mely flammable and explosive.To preventthe possibilityof injury

under these com_ior_ we recommend tbe hot wator faucet

be openedfor severalminutesat the kitchensink beforeany electricalapplianceswhichare connectedto the hot w_r sys- tem are used (suchas a dishwasheror washingmachine).If

hydrogen gasis present, there will probably be an unusual soundsimilarto air escapingthroughthe pipeasthe hot water

Possible noises due to expansion and contraction of some metal parts during periods of beat-up and cool-down do not represent harmful or dangerous conditions.

Condensation causes sizzling and popping with the burner area

during heating and coolin_ periods and should be considered

normal. See "Condensation section.
