Square fire pit burners are designed to complement square fire pit enclosures, yet in practice, many square fire pits are fitted with round burners. There is no technical limitation behind this; the difference is purely visual.
Viewed from above, a round burner placed within a square fire pit leaves the corners visually unlit, creating a softer, more centralized flame pattern. A square burner, by contrast, extends into each corner, producing a more defined flame shape that follows the geometry of the enclosure. The choice ultimately comes down to preferred aesthetics and overall design intent.
Fuel Compatibility
All burners from The Outdoor Plus are suitable for use with both natural gas and liquid propane. When using propane, an air mixer valve must be installed to ensure proper combustion.
Water Runoff Protection
Burner inlets are raised and tapered to help prevent water from entering the gas line. Any water that does enter the burner body is directed away from the inlet.
Integrated Drainage System
Multiple drain holes allow water to escape from the burner. A formed tab at each drainage point helps maintain an upward flame direction, avoiding disruption to the flame pattern often seen in standard designs.
Heavy Duty Stainless Steel Construction
Manufactured from 304 stainless steel with a .065 wall thickness, these burners are built to resist warping and provide long-term durability, even in demanding outdoor environments.
Sizes and Configuration
The range begins at 6 inches square with a single ring and extends up to 60 inches square with four concentric rings. Nine size options are available, allowing flexibility for both new installations and retrofit projects.
A clearance of 3 inches should be maintained between the burner and the inner walls of the fire pit structure.
Smaller sizes, 6 inch, 12 inch, and 18 inch, feature a 1/2 inch gas inlet. Larger models are fitted with a 3/4 inch inlet.
