Air shutter settings should be adjusted by a qualified installer at the time of installation. The air shutter is set at the factory for a minimum vertical vent run. Adjust the air shutter for longer vertical runs.

• 16 full turns of the shutter adjustment handle are required to move the air shutter from fully open to fully closed.

• When the shutter adjustment handle is all the way down, the air shutter is in the closed position.

NOTICE: If sooting occurs, provide more air by opening the air shutter.

WARNING! Risk of Fire or Explosion! High pressure will damage the valve. Low pressure may cause explosion. Verify inlet pressures. Verify minimum pressures when other household gas appliances are operating.

Possible Cause A: No gas or low gas pressure.

Corrective Action: Check the remote shut-off valves from the appliance. Usually, there is a valve near the gas main. There can be more than one valve between the appliance and the main.

Possible Cause B: No LP in tank.

Corrective Action: Check the LP (propane) tank. You may be out of fuel.

Possible Cause C: Ignitor.

Corrective Action: Check the spark at the electrode and pilot. If no spark and the electrode wire is properly connected, replace the ignitor. Verify that there is no short in the electrode wire.

Possible Cause D: Pilot or misaligned electrode (spark at electrode).

Corrective Action: Using a match, light the pilot. If the pilot lights, turn off the pilot and trigger the piezo ignitor button again. If the pilot lights, an improper gas/air mixture caused the bad lighting and a longer purge period is recommended. If the pilot will not light, ensure the gap at the electrode and pilot is one-eighth inch to have a strong spark. If the gap is OK, replace the pilot.

Possible Cause A: Thermocouple.

Corrective Action: Check that the pilot flame impinges on the thermocouple. Adjust the pilot for proper flame impingement. Ensure that the thermocouple connection at the gas valve is fully inserted and tight (hand tighten plus 1/4 turn). Verify proper voltage output from the thermocouple to the valve. Place one millivolt meter lead wire on the thermocouple copper lead. Place the second lead wire on the solder button on the back of the valve (blue wire). Start the pilot and hold the valve knob in. The millivolt reading should be 8-16 millivolts. If the reading is less than 8 millivolts, replace the thermocouple.

Possible Cause B: Improper gas inlet pressure.

Corrective Action: Natural gas should be 5-7 in. w.c. LP should be 11-14 in. w.c. Verify pressure with a manometer.

Possible Cause C: Valve.

Corrective Action: If the thermocouple is producing 8-16 millivolts, replace the control valve.

Possible Cause A: On/off switch or wires defective.

Corrective Action: Check the ON/OFF switch and wires for proper connections. Place the jumper wires across the terminals at the ON/OFF switch. If the burner comes on, replace the ON/OFF switch. If the switch is OK, place the jumper wires across the ON/OFF switch wires at the gas valve. If the burner comes on, the wires are faulty or connections are bad.

Possible Cause B: Thermopile may not be generating sufficient millivoltage.

Corrective Action: Check that the pilot flame impinges the thermopile properly. Be sure the wire connections from the thermopile at the gas valve terminals are tight and that the thermopile is fully inserted into the pilot bracket. Check the thermopile with a millivolt meter at the TH-TP & TP terminals of the gas valve. The meter should read 350 millivolts minimum. Replace the thermopile if the reading is below the specified minimum.

Possible Cause C: Failed valve.

Corrective Action: Turn the valve knob to the ON position. Place the ON/OFF switch in the ON position. Check the millivolt meter at the thermopile terminals. The millivolt meter should read greater than 125mV. If the reading is acceptable, and if the burner does not come on, replace the gas valve.

Possible Cause D: Plugged burner orifice.

Corrective Action: Check the burner orifice for stoppage and remove it.

Possible Cause: Pilot flame may be too high or too low, or blowing out (high pressure), causing pilot safety to drop out.

Corrective Action: Clean the thermocouple and adjust the pilot flame for proper flame impingement. Follow lighting instructions carefully.

Possible Cause A: No LP in tank.

Corrective Action: Check the LP (propane) tank. Refill the fuel tank.

Possible Cause B: Improper gas inlet pressure.

Corrective Action: Verify with a manometer. NG should read 5-14 inches w.c. LP should read 10-14 inches w.c.

Possible Cause C: Inner vent pipe leaking exhaust gases back into the system.

Corrective Action: Check the venting system for damage. Replace/repair improperly assembled pipe sections.

Possible Cause D: Glass installed improperly.

Corrective Action: Check to ensure glass is installed properly. Replace the glass panel assembly.

Possible Cause E: Failed thermopile or thermocouple.

Corrective Action: Replace pilot if necessary.

Possible Cause F: Improper vent cap installation.

Corrective Action: Check for proper installation and freedom from debris or blockage.

Possible Cause A: Flame impingement.

Corrective Action: Adjust the log set so that the flame does not excessively impinge on it. Refer to log instructions.

Possible Cause B: Improper air shutter setting.

Corrective Action: Refer to the manual for shutter set points. Ensure that the set point is correct for the appliance/gas type. If the unit has an adjustable shutter, it may be necessary to increase the shutter opening.

Possible Cause C: Debris around air shutter.

Corrective Action: Inspect the opening at the base of the burner. NO MATERIAL SHOULD BE PLACED IN THIS OPENING.

Possible Cause: Insufficient oxygen being supplied.

Corrective Action: Ensure that the vent cap is installed properly and free of debris. Ensure that the vent system joints are tight and have no leaks. Ensure that no debris has been placed at the base of, or in the area of the air holes in the center of the base pan beneath the burner. Ensure that the glass is tightened properly on the unit, particularly on top corners.

Possible Cause A: Incorrect wiring.

Corrective Action: Verify the “S” wire (white) for the sensor and “I” wire (orange) for the ignitor are connected to the correct terminals on the module and pilot assembly.

Possible Cause B: Loose connections or electrical shorts in the wiring.

Corrective Action: Verify no loose connections or electrical shorts in wiring from the module to the pilot assembly. Verify connections underneath the pilot assembly are tight; also verify connections are not grounding out to the metal chassis, pilot burner, pilot enclosure, mesh screen if present, or any other metal object.

Possible Cause C: Ignitor gap is too large.

Corrective Action: Verify the gap of the ignitor to the right side of the pilot hood. The gap should be approximately .17 inch or 1/8 in. (3 mm).

Possible Cause D: Module.

Corrective Action: Turn the ON/OFF rocker switch or wall switch to the OFF position. Remove the ignitor wire “I” from the module. Place a grounded wire about 3/16 in. (5 mm) away from the “I” terminal on the module. Place the ON/OFF rocker switch or wall switch in the ON position. If there is no spark at the “I” terminal, the module must be replaced. If there is a spark at the “I” terminal, the module is fine. Inspect the pilot assembly for a shorted sparker wire or cracked insulator around the electrode. Replace the pilot if necessary.

Possible Cause A: No power or power supply installed incorrectly.

Corrective Action: Verify that the power supply is installed and plugged into the module. Check the voltage of the power supply under load at the spade connection on the module with the ON/OFF switch in the ON position. Acceptable readings of a good power supply are between 3.2 and 2.8 volts AC.

Possible Cause B: A shorted or loose connection in wiring configuration or wiring harness.

Corrective Action: Remove and reinstall the wiring harness that plugs into the module. Verify there is a tight fit. Verify pilot assembly wiring to the module. Remove and verify continuity of each wire in the wiring harness. Replace any damaged components.

Possible Cause C: Improper wall switch wiring.

Corrective Action: Verify that 110/VAC power is “ON” to the junction box.

Possible Cause D: Module not grounded.

Corrective Action: Verify the black ground wire from the module wire harness is grounded to the metal chassis of the appliance.

Possible Cause A: Gas supply.

Corrective Action: Verify that the incoming gas line ball valve is “open”. Verify that the inlet pressure reading is within acceptable limits.

Possible Cause B: Ignitor gap is incorrect.

Corrective Action: Verify that the spark gap from the ignitor to the pilot hood is .17 in. or 1/8 in (3 mm).

Possible Cause C: Module is not grounded.

Corrective Action: Verify the module is securely grounded to the metal chassis of the appliance.

Possible Cause D: Module voltage output / Valve/ Pilot solenoid ohms readings.

Corrective Action: Verify battery voltage is at least 2.7 volts. Replace batteries if the voltage is below 2.7.

(If the pilot continues to spark after the pilot flame has been lit, flame rectification has not occurred.)

Possible Cause A: A shorted or loose connection in flame sensing rod.

Corrective Action: Verify all connections to the wiring diagram in the manual. Verify connections underneath the pilot assembly are tight. Verify connections are not grounding out to the metal chassis, pilot burner, pilot enclosure or screen if present, or any other metal object.

Possible Cause B: Poor flame rectification or contaminated flame sensing rod.

Corrective Action: With the fixed glass assembly in place, verify that the flame is engulfing the flame sensing rod on the left side of the pilot hood. The flame sensing rod should glow shortly after ignition. Verify the correct pilot orifice is installed and the gas inlet is set to pressure specifications.

Possible Cause C: Module is not grounded.

Corrective Action: Verify the module is securely grounded to the metal chassis of the appliance. Verify that the wire harness is firmly connected to the module.

Possible Cause D: Damaged pilot assembly or contaminated flame sensing rod.

Corrective Action: Verify that the ceramic insulator around the flame sensing rod is not cracked, damaged, or loose. Verify the connection from the flame sensing rod to the white sensor wire. Clean the flame sensing rod with emery cloth to remove any contaminants. Verify continuity with a multimeter with ohms set at the lowest range. Replace the pilot if any damage is detected.

Possible Cause E: Module.

Corrective Action: Turn the ON/OFF rocker switch or wall switch to the OFF position. Remove the ignitor wire “I” from the module. Place the switch in the ON position. If there is no spark at the “I” terminal, the module must be replaced. If there is a spark at the “I” terminal, the module is fine.
