assembly are tight; also verify connections are not grounding out to

 

 

metal chassis, pilot burner, pilot enclosure, mesh screen if present,

 

 

or any other metal object.

 

 

 

 

C. Ignitor gap is too large.

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

 

 

approximately .17 inch or 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 around electrode. Replace pilot if necessary.

 

 

 

2. Pilot won’t light, there is no

transformer are between 3.2 and 2.8 volts AC.

 

 

 

 

B. A shorted or loose connection

Remove and verify continuity of each wire in wiring harness.

 

 

Replace any damaged components.

 

 

 

 

C. Improper wall switch wiring.

Verify that 110/VAC power is “ON” to junction box.

 

 

 

 

D. Module not grounded.

Verify black ground wire from module wire harness is grounded to

 

 

metal chassis of appliance.

 

E. Module.

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

 

 

ignitor wire “I” from 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

 

 

around electrode.

pressure reading is within acceptable limits, inlet pressure must not

 

 

exceed 14 in. W.C.

 

B. Ignitor gap is incorrect.

Verify that spark gap from ignitor to pilot hood is .17 in. or 1/8 in (3

 

 

mm).

 

C. Module is not grounded.

Verify module is securely grounded to metal chassis of appliance.

 

 

 

 

D. Module voltage output / Valve/
