What to Consider When Building a Gas Fire Pit:

  • Gas Supply - Before you begin designing your fire pit, first determine your gas supply
    • Both Natural Gas and Propane may be used - Supply Pressure and BTU ratings need to be regulated for both
    • For Natural Gas: Supply Pressure should be set between 3.5" - 7" Water Column
    • For Propane*: Supply Pressure should be set between 8" - 11" Water Column
    • *If using a 20 lb. propane tank, consider the maximum BTU output of a tank that size ranges from about 90,000 - 125,000 BTU† and a regulator must be used
    • †The BTU rating of the 20 pound tank limits your burner options to sizes that are rated for 125,000 or fewer BTU
  • Fire Pit Burner - The shape and size of your fire pit burner can be choosed after determining your gas supply
    • Choose a burner that's at least 6" smaller than the inside dimension of your enclosure - that's 3" between the edge of the burner and the inside edge of the pit
  • Fire Pit Pan - Recommended for use with all fire pit burners, but required for use in propane applications
    • A pan can be flat or "bowl" style in order to accommodate your construction - it should be installed at least 3-4" below the top surface of your enclosure
    • The burner pan separates the air mixer from the burner in propane applications, but in all constructions it helps with water drainage and ventillation
  • Flange Extension - In many cases, the shut-off valve will be located inside the fire pit - if your enclosure walls are thicker than 3" it may be necessary to use a flange extension and a longer key
  • Ventilation - For all fire pit burners, adequate ventilation is required
    • The recommended amount of ventilation is 36in² - or (2) 18in² vents on two opposing sides to create proper airflow
  • Installation Collars - Are designed to simplify the installation of a fire pit pan
    • Our flexible installation collars can bend for round enclosures, and can be anchored in with concrete screws
  • Fire Media - Is the final step to finishing a gas fire pit
    • Both lava rock and fire glass may be used to complete your fire pit, the choice between the two is purely aesthetic
