IGNITER/ELECTRODE TESTING AND
REPLACEMENT
With the pilot not in operation (no pilot flame) the igniter and electrode circuit function can be observed by
opening the combustion chamber door and viewing whether there is a sparking action.
Step 1. Make sure the gas control is in the “OFF” position.
Step 2. Remove outer jacket door.
Step 3. Slide open or remove the inner
combustion chamber door.
Step 4. Depress the igniter button repeatedly while viewing
the spark through the open door of the combustion
chamber. If there is no spark proceed to Step 5.
If there is a spark, the igniter is OK.
Step 5. Remove the lead wire from the igniter at the connector
provided for this. Hold the igniter lead from the gas valve
close to an unpainted metal surface (such as the burner feedline)
and depress the igniter button (see Figure 15). If there is a spark the igniter is OK.
If no spark is present the igniter is not functioning and the gas control
must be replaced per Service Procedure AG-III page 18.
