Condensation Whenever the water heater is filled with cold water, some condensate will 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 particularly high efficiency are lower. water vapor In water heaters, models where flue temperatures 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". 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 wi!l 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. from hydrogen sulfide gas dissolved in the water. 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 non4oxic 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 '_.r\ ) Explosion Hazard Flammable hydrogen gases may be present , Keep all ignition sources away from faucet when turning on hot water, 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 I 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. 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. Operational Conditions Hig h Temperature Shut Off System Smelly Odor This water heater is equipped with an automatic gas shutoff system. This system works when high water temperatures In each water heater there is installed at least one anode rod are present. Turn 'OFF" the entire gas supply to the water (see parts section) for corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and heater. The high temperature valve. It is non-resettable. shutoff is built into the gas control If the high temperature shutoff the water. The most common complaint associated with the activates, the gas control valve must be replaced. Contact your anode rod is one of a 'rotten egg smell". This odor is derived gas supplier. 24
