Anode deterioration depends on water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by a qualified technician, and at a minimum should be checked annually after the warranty period.

A hydrogen sulfide (rotten egg) odor may result if water contains high sulfate and/or minerals. Chlorinating the water supply should minimize the problem . (See

EXTENDED NON-USE PERIODS).

NOTE: Anode must remain installed (except for inspection) to avoid shortening tank life. See LIMITED WARRANTY. Replace as necessary.

For your safety, water heater service should be performed only by a qualified service technician. Read the GENERAL SAFETY INFORMATION section first.

WATER HEATING IGNITION SEQUENCE

(Make sure gas and electric power are connected properly)

1)The ignition control module is powered and monitors the system, waiting for a call for heat from the thermostat.

2)The thermostat calls for heat by reading a resistance value within a given range directly proportional to water temperature.

3)The Control Module:

a)Check the pressure switches for an open circuit.

b)Energizes the blower.

c)Checks the pressure switches for a closed circuit to prove draft.

d)Sends line voltage to the hot surface igniter with a 20-second warm up period.

e)Opens the gas valve and checks the sensing rod for flame.

4)The burner heats the water to the desired thermostat setting.

a)The resistance in the thermostat rises to the value selected by the temperature control knob.

b)The control module closes the gas valve and 5 seconds later, removes power from the blower.

5)Cycle is completed.
