other metal object.

 

 

 

 

c. Ignitor gap is too large.

Verify gap of igniter to right side of pilot hood. The gap should be

 

 

approximately 1/8 in (3 mm).

 

 

 

 

d. Module.

Turn ON/OFF rocker switch or wall switch to OFF position. Remove

 

 

ignitor wire “I” from module. Place a grounded wire about 3/16 in. (5

 

 

mm) away from “I” terminal on module. Place ON/OFF rocker switch

 

 

or wall switch in ON position. If there is no spark at “I” terminal module

 

 

must be replaced. If there is a spark at “I” terminal, module is fine.

 

 

Inspect pilot assembly for shorted sparker wire or cracked insulator
