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	PROBLEM	TEST SOLUTION
Pilot will not light.	- Wiring	Verify the "S" wire for the sensor and the "I" wire for the ignitor are
Makes noise with no		connected to the correct terminals (not reverse) on the module and
spark at pilot burner	- Loose connection	pilot assembly.
		Verify no loose connections, electrical shorts in the wiring or ground
	- Module	out to any metal object.
		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 .125" (1/8").
	incorrect

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 a simple ON/OFF switch
- Module is not grounded		Verify the valve 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.

- Out of propane gas.

- fill the tank.

Continues to sparks and pilot lights, but main burner will not light

- Short or loose	Verify all connections. Verify the connections from the pilot assembly
connection in sensor rod	are tight; also verify these connections are not grounding out to any
	metal.
- Poor flame rectification	Verify the flame is engulfing the sensor rod. This will increase the
or contaminated	flame rectification. Verify correct pilot orifice is installed and inlet gas
sensor rod	specifications to manual. (Remember, the flame carries the rectifica-
	tion current, not the gas. If the flame lifts from pilot hood, the circuit
	is broken. A wrong orifice or too high of an inlet pressure can cause
	the pilot flame to lift.) The sensor rod may need cleaning.
- Poor grounding between	Verify that the wire harness is firmly connected to module
pilot assembly and
gas valve
- Damaged pilot or dirty	Verify that the ceramic insulator around the sensor rod is not cracked,
sensor rod	damaged, or loose. Verify the connection from the sensor rod to the
	sensor wire. Clean sensor rod with an emory cloth to remove any
	contamination that may have accumulated on the sensor rod. Verify
	continuity with multimeter with ohms set at the lowest range.
