4. Installation / Setup

IMPORTANT: Due to the nature of gas appliances and the critical safety aspects involved, installation of this pilot assembly should only be performed by a qualified and certified professional. Attempting to install this part without proper training and tools can lead to serious injury, property damage, or death.

A qualified technician will follow these general steps:

1. Preparation: Ensure the fireplace is completely cool, and disconnect all gas and electrical supplies to the unit.
2. Access: Remove any necessary panels or logs to gain access to the existing pilot assembly.
3. Removal: Carefully disconnect the gas line, thermocouple, and thermopile wires from the old pilot assembly. Unmount the old assembly.
4. Installation: Mount the new 69L18 pilot assembly in the correct orientation. Reconnect the gas line, ensuring all connections are tight and secure. Reconnect the thermocouple and thermopile wires to their respective terminals.
5. Leak Test: After all connections are made, a thorough leak test must be performed using an approved leak detection solution.
6. Testing: Restore gas and electrical supply. Test the pilot ignition and main burner operation according to the fireplace manufacturer's instructions.
7. Reassembly: Replace all panels and logs.

5. Operation (Post-Installation)

Once the 69L18 Pilot Assembly is correctly installed by a qualified professional, its operation is integrated with your fireplace's control system.

• The pilot assembly is responsible for providing a small, continuous flame (pilot light) that ignites the main burner when the fireplace is turned on.
• The thermocouple and thermopile components within the assembly generate a small electrical current that signals to the gas valve that the pilot light is lit, allowing the main gas flow to the burner.
• Refer to your specific fireplace model's user manual for instructions on lighting the pilot and operating the main burner.

6. Maintenance

Regular maintenance of your fireplace, including the pilot assembly, is essential for safe and efficient operation. This should be performed by a qualified service technician annually.

• Cleaning: Over time, dust, lint, or debris can accumulate around the pilot burner, potentially affecting its flame. A technician can carefully clean the pilot orifice and surrounding area.
• Flame Inspection: The pilot flame should be strong, steady, and blue, with possibly a small yellow tip. An irregular, weak, or yellow flame may indicate a problem requiring professional attention.
• Component Check: A technician will inspect the thermocouple and thermopile for any signs of wear, corrosion, or damage that could affect their ability to generate sufficient voltage.

Do not attempt to clean or adjust the pilot assembly yourself if you are not a qualified professional.

7. Troubleshooting

If you experience issues with your fireplace's ignition or operation after installing this pilot assembly, consult a qualified service technician. Common issues related to the pilot assembly include:

• Pilot Light Not Staying Lit: This is often caused by a weak thermocouple or thermopile, which fails to generate enough voltage to keep the gas valve open. It could also be due to a dirty pilot orifice or improper flame impingement.
• No Pilot Ignition: This could be due to a faulty igniter, no gas supply to the pilot, or a blocked pilot orifice.
• Main Burner Not Igniting: If the pilot light is on but the main burner doesn't ignite, it could indicate an issue with the thermopile, the main gas valve, or the fireplace's control system.

For all troubleshooting and repairs, it is strongly recommended to contact a certified gas appliance technician.
