Troubleshooting Guide
Start Up Conditions
CONDENSATION
Whenever the water heater is filled with cold water, a certain
amount of condensation will form while the burner is on. A water heater may appear to be leakingwhen in fact the water is condensation, This usually happens when:
•When a new water heater is filled with cold water for the first time.
heaters, particularly high efficiency models where flue tem-
i hen gas burns and water vapor isproduced in water pera_res are lower.
When you use large amounts of hot water in a short time and the refillwater 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 run- ning 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
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 ate at their lowest.
THERMAL EXPANSION
Water supply systems may, because of high line pressure, fre- quent
tem to be dosed. As water is heated, it expands (thermal expan- sion) and closed systems do not allow for the expansion of heat- ed water.
The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater's
reached, the valve w_ll relieve the excess pressure. The tempera-
relief of thermal expansion. This is an unacceptable condition and must be corrected.
It is recommended that any devices installed which could create a closed system have a
through the Sears Service Center. Contact the local plumbing inspector, water supplier, and/or the Sears Service Center for assistance in controlling these situations.

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.

pressure, but must not be higher than 80 psi.
