TROUBLE SHOOTING GUIDE

BEFORE ATTEMPTING TO TROUBLESHOOT, PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR REMOVED.

SYMPTOM

TEST SOLUTION

Pilot will not light.

Turn the ON/OFF switch to the "OFF" position. Remove the igniter

 

 

wire "I" from the module. Place the ON/OFF switch to the "ON" posi-

 

 

tion. Hold a grounded wire about 3/16" away from the "I" terminal on

 

 

the module. If no spark the "I" terminal module must be replaced. If

 

 

there is a spark the "I" terminal is fine. Inspect pilot assembly for a

 

 

shorted wire or cracked insulator around the electrode.

 

- Igniter Spark gap is

- spark gap of the ignitor to the pilot should be .17" tor 1/8"

 

incorrect

 

- Out of propane gas.

- fill the tank.

Pilot will not light. Makes no noise with no spark at pilot burner

-

Transformer

Verify the transformer is installed and plugged into the module. Check

 

 

voltage of the transformer under load at the spade connections on

 

 

the module with the ON/OFF switch in the "ON" position. Acceptable

 

 

readings of a good transformer are between 3.2 and 2.8 volts A.C.

-

A shorted or loose

Remove and reinstall the wiring harness that plugs into the module.

 

Connection

Remove and verify continuity of each wire in wiring harness.

- Improper switch wiring

Troubleshoot the system with the simplest ON/OFF switch

- Module is not grounded

Verify the value and pilot assemblies are properly grounded to the

 

 

metal chassis of the fireplace or log set.

- Faulty module

Turn the ON/OFF switch to the "OFF" position. Remove the igniter

 

wire "I" from the module. Place the ON/OFF switch to the "ON" posi- tion. Hold a grounded wire about 3/16" away from the "I" terminal on the module. If no spark the "I" terminal module must be replaced. If there is a spark the "I" terminal is fine. Inspect pilot assembly for a shorted wire or cracked insulator around the electrode.

Pilot sparks but will not light

- Gas supply

Verify that the incoming gas line ball valve is "Open". Verify that the

 

 

 

 

 

 

inlet pressure reading is within acceptable limits, inlet pressures must

 

 

 

 

 

 

not exceed 14" W.C.

 

 

 

 

 

- Module is not grounded

Verify the value and pilot assemblies are properly grounded to the

 

 

 

 

 

 

metal chassis of the fireplace or log set.
