• Engage the top access latches.

• Engage the lower access latches.

• Reinstall the top corners of the screen assembly in their retainer clips and rotate the screen assembly to rest on the lower latches.

• Close the access panel and reinstall the upper grille.

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.

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

If after repeated triggering of the piezo ignitor button, the spark ignitor will not light the pilot, check the following:

• No gas or low gas pressure: Check the remote shut-off valves from the appliance. There is usually a valve near the gas main.

• No LP in tank: Check the LP (propane) tank. You may be out of fuel.

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

• Pilot or misaligned electrode: Using a match, light the pilot. If it lights, turn it off and trigger the ignitor again. If the pilot lights, an improper gas/air mixture may require a longer purge period. If it will not light, ensure the gap at the electrode and pilot is one-eighth inch. If the gap is okay, replace the pilot.

If the pilot will not stay lit after carefully following the lighting instructions, check the following:

• Thermocouple: Check that the pilot flame impinges on the thermocouple and adjust if needed. Ensure the thermocouple connection at the gas valve is fully inserted and tight (hand tighten plus 1/4 turn). Verify proper voltage output (8-16 millivolts). If the reading is less than 8 millivolts, replace the thermocouple.

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

• Valve: If the thermocouple is producing 8-16 millivolts, replace the control valve.

If the pilot is burning but the main burner won’t light with the valve knob and ON/OFF switch in the ON position:

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

• Thermopile may not be generating sufficient millivoltage: Check that the pilot flame properly impinges on the thermopile and that wire connections are tight. Check the thermopile with a millivolt meter; it should read 350 millivolts minimum. If the reading is below the minimum, replace the thermopile.

• Failed valve: Check the millivolt meter at the thermopile terminals. It should read greater than 125mV. If the reading is acceptable and the burner does not come on, replace the gas valve.

• Plugged burner orifice: Check the burner orifice for stoppage and remove it.

A pilot flame that may be too high or too low, or is blowing out due to high pressure, can cause the pilot safety to drop out. Clean the thermocouple and adjust the pilot flame for proper flame impingement. Follow the lighting instructions carefully.

• No LP in tank: Check the LP (propane) tank and refill if necessary.

• Improper gas inlet pressure: Verify with a manometer. NG should be 5-14 inches w.c. and LP should be 10-14 inches w.c.

• Inner vent pipe leaking: Check the venting system for damage and repair or replace improperly assembled pipe sections.

• Glass installed improperly: Check to ensure the glass is installed properly. Replace the glass panel assembly if needed.

• Failed thermopile or thermocouple: Replace the pilot if necessary.

• Improper vent cap installation: Check for proper installation and ensure it is free from debris or blockage.

• Flame impingement: Adjust the log set so that the flame does not excessively impinge on it.

• Improper air shutter setting: Refer to the manual for shutter set points. If the unit has an adjustable shutter, it may be necessary to increase the shutter opening.

• Debris around air shutter: Inspect the opening at the base of the burner. No material should be placed in this opening.

This indicates insufficient oxygen is being supplied. Ensure that the vent cap is installed properly and free of debris. Ensure that the vent system joints are tight and have no leaks. Make sure 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. Also, ensure that the glass is tightened properly on the unit, particularly on the top corners.

• Incorrect wiring: 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.

• Loose connections or electrical shorts: Verify there are no loose connections or shorts in the wiring from the module to the pilot assembly. Check that connections are not grounding out to the metal chassis or other objects.

• Ignitor gap is too large: Verify the gap of the ignitor to the right side of the pilot hood is approximately 1/8 in. (3 mm).

• Module: Test the module by placing a grounded wire about 3/16 in. away from the “I” terminal. If there is no spark, the module must be replaced. If there is a spark, inspect the pilot assembly for a shorted sparker wire or cracked insulator.

• No power or power supply installed incorrectly: Verify the power supply is installed and plugged into the module. Check the voltage under load; it should be between 2.8 and 3.2 volts AC.

• A shorted or loose connection: Remove and reinstall the wiring harness that plugs into the module. Verify a tight fit and check the continuity of each wire in the harness.

• Improper wall switch wiring: Verify that 110/VAC power is “ON” to the junction box.

• Module not grounded: Verify the black ground wire from the module wire harness is grounded to the metal chassis of the appliance.

• Module: Test for a spark at the “I” terminal. If there is no spark, the module must be replaced. If there is a spark, inspect the pilot assembly for a shorted wire or cracked insulator.

• Gas supply: Verify that the incoming gas line ball valve is “open” and that the inlet pressure reading is within acceptable limits.

• Ignitor gap is incorrect: Verify that the spark gap from the ignitor to the pilot hood is approximately 1/8 in. (3 mm).

• Module is not grounded: Verify the module is securely grounded to the metal chassis of the appliance.

• Module voltage output / Valve/Pilot solenoid ohms readings: Verify battery voltage is at least 2.7 volts. Replace batteries if the voltage is below 2.7.

This indicates that flame rectification has not occurred. Here are possible causes and corrective actions:

• A shorted or loose connection in the flame sensing rod: Verify all connections per the wiring diagram and ensure they are tight and not grounding out.

• Poor flame rectification or contaminated flame sensing rod: With the glass assembly in place, verify that the flame is engulfing the flame sensing rod on the left side of the pilot hood. The rod should glow shortly after ignition. Verify the correct pilot orifice is installed and gas inlet pressure is correct.

• Module is not grounded: Verify the module is securely grounded to the metal chassis and the wire harness is firmly connected.

• Damaged pilot assembly or contaminated flame sensing rod: Verify the ceramic insulator is not cracked, damaged, or loose. Clean the flame sensing rod with emery cloth. Verify continuity with a multimeter. Replace the pilot if any damage is detected.

• Module: Test for a spark at the “I” terminal on the module. If there is no spark, the module must be replaced. If there is a spark, the module is fine.
