Condensation

Whenever the water heater is filled with cold water, some

condensate wil! form while the burner is on. A water heater may appear to be leaking when in fact the water is condensation. This usually happens when:

•A new water heater is filled with cold water for the first time.

Burning gas produces water vapor In water heaters,

particularly high efficiency models where flue temperatures are lower.

Large amounts of hot water are used in a short time and the refill water in the tank is very cold.

Moisture from the products of combustion condense on the cooler tank surfaces and form drops of water which may fall onto the burner or other hot surfaces to produce a "sizzling" or 'frying" noise.

Excessive condensation can cause pilot outage due to water running down the flue tube onto the main burner and putting out the pilot.

Because of the suddenness and amount of water,

condensation water may be diagnosed as a 'tank leak'L After the water in the tank warms up (about 1-2 hours), the condition should disappear.

Do not assume the water heater is leaking until there has been enough time for the water in the tank to warm up.

An undersized water heater will cause more condensation. The water heater must be sized properly to meet the family's

demands for hot water including dishwashers, washing

machines and shower heads.

Excessive condensation may be noticed during the winter and

early spring months when incoming water temperatures are at their lowest.

Good venting is essential for a gas fired water heater to operate

properly as well as to carry away products of combustion and water vapor.

Smoke Odor

It is not uncommon to experience a small amount of smoke and odor during the initial start-up. This is due to burning off of oil from metal parts, and will disappear in a short while.

Operational Conditions

Smelly Odor

In each 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 waten 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 waten The smell is the result of four factors which must al! be present for the odor to develop:

*a concentration of sulfate in the supply water.

little or no dissolved oxygen in the water.

a sulfate reducing bacteria within the water heater. (This harmless bacteria is nomtoxic to humans.)

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 al! hot water lines. Contact Sears Service for further information

concerning an Anode Replacement Kit #9001453 and this

Chlorination Treatment. Anode replacement and chlorination of the tank are not covered by the water heater's limited warranty.

if the smelly water persists after the anode replacement and

chlorination treatment, it may be necessary to chlorinate or aerate your water supply to eliminate the problem.

Do not remove the anode leaving the tank unprotected, By

doing so, all warranty on the water heater tank is voided.

"AIR" In Hot Water Faucets

)

Explosion Hazard

, Flammable hydrogen gases may be present.

Keep all ignition sources away from faucet when turning on hot water

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, located farthest away, be opened for several minutes before any electrical appliances which are connected to the hot water

system 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.

High Temperature Shut-Off System

This water heater is equipped with an automatic gas shutoff

system. This system works when high water temperatures

are present. Turn 'OFF" the entire gas supply to the water

heater. The high temperature shutoff is built into the gas contro!

valve. It is nomresettable. If the high temperature shutoff activates, the gas control valve must be replaced. Contact your gas supplier.
