The BTU rating will depend on the style of burner you choose. For this burner, the closest model to 20 inches, the CFB290 (21.5 x 21.5 inches), is rated for a maximum of 290,000 BTU. To prevent whistling noise, ensure you follow the steps under our "What to Consider" section. Specifically, you will want to ensure proper supply pressure at the burner. You will also want to ensure none of your flex lines have severe bends, as this can also cause a whistling noise to occur.

This burner met and exceeded my expectations. I was considering a larger size but Im happy i followed your recommendation for clearance as the burner puts out a LOT of flame.

It's an expensive item but the quality shows through on the product itself and the documentation that comes with it. The burner's performance was exactly as expected.

Wow...this burner assembly is incredible! The entire thing is assembled from brass pipe and fittings. The jets are set at such an angle that from the low fire setting to full throttle, the flames have a very convincing natural looking taper. The heat produced from this option is amazing. So far we have only needed to run the fire pit at maybe ¼ to ⅓ of its rated capacity....that said, full throttle is fun and beautiful. Everyone who has been over wants one.

What to Consider

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

How Many Installation Collars Do I Need?
Round Pan Size (Diameter)*	Number of Collars
12”	2 Units
18”	3 Units
24”	4 Units
30”	5 Units
36”	6 Units
42”	7 Units
48”	8 Units
54”	9 Units
*NOTE: For square or rectangular enclosures, use enclosure length and width measurements

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
