Key components include:
- Pilot Burner: Provides a small, continuous flame to ignite the main burner.
- Thermocouple/Thermopile: Generates a small electrical current when heated by the pilot flame, which signals the gas valve to remain open. This is a safety device.
- Igniter Electrode: Creates a spark to light the pilot flame.
- Pilot Tube: Delivers gas to the pilot burner.

5. Setup and Installation
Installation of a pilot assembly involves working with gas lines and electrical components. For safety and proper function, it is strongly recommended that installation be performed by a qualified and certified gas technician.
General Steps (for reference only - consult a professional):
- Safety First: Turn off the gas supply to the appliance and disconnect electrical power. Allow the appliance to cool completely.
- Access: Carefully remove any decorative elements, logs, or panels to gain access to the existing pilot assembly.
- Disconnect Old Assembly: Disconnect the gas line, thermocouple/thermopile, and igniter wire from the old pilot assembly and the gas valve/control board. Note the routing of all connections.
- Remove Old Assembly: Unmount the old pilot assembly from its bracket.
- Install New Assembly: Mount the new 69L18, 108084-03 Pilot Assembly onto the bracket in the same orientation as the old one.
- Connect Components: Reconnect the gas line, thermocouple/thermopile, and igniter wire to the new pilot assembly and the appropriate terminals on the gas valve/control board. Ensure all connections are secure and properly tightened.
- Leak Test: Turn the gas supply back on. Apply a leak detection solution (soap and water mixture) to all gas connections. Bubbles indicate a leak. If a leak is detected, shut off the gas immediately and tighten the connection until no bubbles appear.
- Restore Power: Restore electrical power to the appliance.
- Test Operation: Follow the appliance's specific lighting instructions to test the pilot and main burner operation.

6. Operating Instructions
The pilot assembly's operation is integrated with your fireplace's control system. Once installed, its primary function is to provide a reliable ignition source for the main burner.
To operate your fireplace with the new pilot assembly:
- Ensure the gas supply to the fireplace is open.
- Follow the specific lighting instructions provided in your fireplace's original user manual. This typically involves turning a control knob to a 'Pilot' position, pressing it in, and then activating the igniter until the pilot flame lights.
- Once the pilot flame is established and stable (usually after holding the knob for 30-60 seconds), release the knob and turn it to the 'ON' position to engage the main burner.
- Observe the pilot flame. It should be strong, blue, and engulf the tip of the thermocouple/thermopile.
If the pilot flame does not light or extinguishes, refer to the Troubleshooting section or consult a qualified technician.
7. Maintenance
Regular maintenance helps ensure the longevity and safe operation of your pilot assembly and fireplace. Always ensure the gas supply is off and the appliance is cool before performing any maintenance.
- Annual Inspection: Have a qualified technician inspect your fireplace and pilot assembly annually.
- Pilot Flame Check: Periodically observe the pilot flame. It should be steady, blue, and consistently impinge on the thermocouple/thermopile. A weak, yellow, or flickering flame may indicate a problem.
- Cleaning: Gently clean any dust, lint, or debris from around the pilot burner and thermocouple/thermopile using a soft brush or compressed air. Do not use harsh chemicals.
- Ventilation: Ensure that the appliance's vents and air passages are clear and unobstructed.
- Component Integrity: Visually inspect the pilot assembly, wires, and tubing for any signs of wear, corrosion, or damage. Replace any damaged components immediately.
