A.O. Smith BT- 65 Water Temperature Is Too Hot, Gas Smellat The Heater, Water Heater Makes Sounds

WATER TEMPERATURE IS TOO HOT

1.The thermostat water temperature adjusting dial may be set too high.

2.If lowering control setting does not reduce the water temperature contact your dealer.

GAS SMELLAT THE HEATER

1.Close the main Shut-off valve in the gas supply pipe near the heater, see fig. 4 on page 8. The thermostat includes a gas control (top knob) which can also be closed.

2.Call your gas company.

WATER LEAKAGE IS SUSPECTED

1.Check to see if the heater drain valve is tightly closed.

2.The apparent leakage might be condensation. In warm or humid locations, condensation can accumulate and run from within the heater or its piping.

•When a water heater is first installed and filled, the bottom of the tank might condense water. The water accumulation, if excessive, can drip into the floor shield. Also, during normal operation there may be occasions when large quantities of water are drawn, chilling the tank bottom. This too can result in condensation.

•Condensation, appearing in the vent pipe (water dripping from draft diverter) during heater operation is evidence of

poor vent action. Possible causes are too long a vent pipe or improper chimney operation.

3.If the leakage is from the temperature and pressure relief valve or its discharge pipe, it may represent a normal condition. However, see RELIEF VALVE section on page 12. DO NOT PLUG THE TEMPERATURE AND PRESSURE RELIEF VALVE. Also, the leakage could be due to unusually high water pressures or temperatures in the system, or to a faulty relief valve. Your dealer or a qualified service technician should be called to determine the cause of the problem and to correct it.

4.If you cannot identify or correct the source of water leakage:

•Close the main Shut-off valve in the gas supply pipe at the heater. See fig. 4, page 8.

•Close the valve which feeds water to the cold water inlet at the top of the heater.

•Contact your dealer.

WATER HEATER MAKES SOUNDS

1.Occasional excessive condensation, as explained under LEAKAGE, can cause a sizzling sound as the moisture is vaporized by the gas flame. This is a normal sound and may be disregarded.

2.Sediment and water scale accumulations may cause rumbling noises. Contact your dealer for details of flushing the heater.

3.If you cannot identify or remedy the condition, contact your dealer.
