Bundle Item Options

1. Burner
The Octagonal Crossfire Burner is available in sizes ranging from 140K BTU (12.5x14.5 inches) to 360K BTU (29.5x27.5 inches), providing flexibility to suit different fire pit designs.

2. Plate Or Pan
Crafted from high-quality tempered aluminum, plates, and pans are available in square or circular shapes. They feature precision-cut weep holes for drainage and come in 1/8" or 3/16" thickness. Each has a central gas inlet opening. Select the size based on your fire pit opening.

3. Flex Line & Key Valve Kit
Choose the appropriate Flex Line & Key Valve Kit based on burner BTUs:

  • FK1 – For burners below 249K BTU
  • FK2 – For burners above 249K BTU

4. Ignition Type
Four ignition options are available to match your preferences:

  • Match Light Ignition – Open the gas valve and ignite with a match or lighter. This is the default system.
  • Push Button Spark Ignition – Open the gas valve and press the ignitor button for easy lighting. No match is required.
  • Push Button Spark with Flame Sense – Adds a flame sensor that automatically shuts off the gas if the flame goes out. No external power is needed.
  • Electronic Ignition – Provides remote on/off functionality with built-in flame sensing. Some models may require external power for high BTU burners.

5. Venting
Proper ventilation is recommended with two 18-square-inch vents on opposite sides for cross ventilation. Adjustments can be made, but ensuring adequate airflow is essential.

6. Installation Collars
Install collars 4-5 inches below the top of the fire pit to support the plate. Bricks or cinder blocks can substitute, but support collars are specifically designed to hold the plate securely.

7. Cover
Protect your fire pit from the elements by covering it when not in use. Aluminum covers are available, but a tarp can work temporarily. Choose a cover with a 1-inch lip around the opening (e.g., a 34" cover for a 32" opening).
