■
Refer to Fig. 11 (AD100/250) or Fig. 12 (AD060) for
servicing of the igniter assembly.
■ The igniter/sensor assembly may require cleaning due
to accumulations of dust and dirt over a period of
time, affecting its ability to ignite fuel gas and sense
burner flame. Cleaning will require igniter/sensor
removal.
-- If spark appears to be weak, rub the igniter
electrode with emery cloth or steel wool to remove
any buildup.
