4. Setup and Installation
Important: Installation must be performed by a qualified professional and comply with all local codes and regulations.
4.1 Pre-Installation Checks
- Ensure the fireplace is clean and free of debris.
- Confirm that the existing gas supply line is Natural Gas (NG) and has a 3/8" or 1/2" male flare gas stub.
- Verify that the fireplace opening and firebox dimensions are suitable for an 18-inch burner and logs.
- Turn off the gas supply at the main valve before beginning any work.
4.2 Installation Steps
- Position the Burner: Carefully place the Dreffco dual row burner pan into the fireplace. Ensure it is centered and stable. The burner has a 1/2-inch connection hub on both ends, allowing connection from either side.
- Connect the Flex Line: Attach one end of the black non-whistle flex line to one of the 1/2-inch connection hubs on the burner pan. Use a wrench to tighten securely, but do not overtighten.
- Connect to Gas Supply: Use the appropriate 3/8" or 1/2" fitting to connect the other end of the flex line to your incoming gas stub. Ensure all connections are tight.
- Secure the Vent-Clip: If applicable, use the vent-clip to secure the flex line or other components as needed to prevent obstruction or damage.
- Check for Leaks: Turn on the main gas supply. Apply a soap and water solution to all new gas connections. Bubbles indicate a leak. If a leak is detected, turn off the gas supply immediately, tighten the connection, and re-test. Repeat until no leaks are present.
- Arrange Glowing Embers: Distribute the bonus bag of glowing embers over the burner pan. These embers enhance the visual effect of the flames.
- Place Fire Logs: Arrange your 18-inch vented fire logs over the burner pan, ensuring they do not obstruct the burner ports or pilot light (if applicable). Allow for proper airflow around the logs.
