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 restllt 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
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 persists after the anode replacement and chlo- rination treatment, we can only suggest that continuous chlori-
nation and filtering conditioning equipment he considered to eliminate the water problem.

"AIR" IN HOT WATER FAUCETS
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet be opened for several minutes at the kitchen sink before any electrical appliances which are connected to the hot water sys- tem are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.
Condensation causes sizzling and popping with the burner area
during beating and coolln{_ periods and should be considered normal. See Condensation section.
