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
- *Do not use a burner rated for greater than 125,000 BTU with a 20-pound propane tank.
Fire Pit Burner - The shape and size of your fire pit burner can be choosed after determining your gas supply
- Choose a burner kit based off of the inside dimension of your enclosure - the fire pit pan will be 6" larger than the burner to provide at least 3" between the edge of the burner and the inside edge of the pit
Fire Pit Pan - Included with all of HPC's preassembled fire pit kits
- 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
- An external shut off valve is not required with this kit, but may be an option for added safety
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
