Highlights
- 【More Flame Coverage – On Any Table Shape】 - A round burner works well in a round table, but in a square or rectangular table? It leaves cold corners and wasted space. Square burner gives you more flame area than a round burner of the same diameter – on any table shape. Its wider flame pattern pushes heat outward for better coverage. No matter your table shape, you get more fire, more heat, less waste. (Fact: 12" square = 144 sq in vs 12" round = 113 sq in – that's 27% more flame coverage.)
- 【Heavy-Duty 304 Stainless Steel – Built for Outdoor Living】 - Crafted from commercial-grade 304 stainless steel – not cheaper 201. Resists rust, corrosion, and high heat. Precision-drilled gas ports ensure smooth, whistle-free flow. Weep holes prevent water buildup. This insert is made to last through seasons of backyard enjoyment.
- 【Complete Drop-in Assembly – Ready for DIY Installation】 - Includes 18" square pan with 12" square burner pre-installed. 1/4" flange on all sides for simple drop-in into any fire pit or table opening. 1/2" center NPT inlet for easy gas connection. No welding, no complex assembly – just drop, connect, and enjoy.
- 【Versatile Fuel Compatibility – Natural Gas or Propane】 - Works with both natural gas and propane (air mixer required for propane – sold separately). Rated at 92,000 BTU. Compatible with fire glass, lava rock, or ceramic logs (minimum 2" depth recommended).
- 【DIY-Friendly & Customizable – Create Your Style】 - Choose your favorite fire glass color or lava rock to match your patio decor. The clean square flame pattern creates a modern, upscale look. Perfect for backyard fire tables, poolside lounges, or commercial patios. Upgrade your outdoor space with a professional-grade fire feature.

Detailed Review
The onlyfire 18-inch Square Fire Pit Burner Pan is an insert designed for custom DIY fire tables and outdoor patio features. Building a fire pit often leaves builders deciding between burner shapes, and square designs help eliminate cold corners. With an output rating of 92,000 BTU, this unit is well suited for homeowners looking to build or upgrade an outdoor fire table with substantial heat output and a clean layout.
Durability is a key focus in the construction, which uses commercial-grade 304 stainless steel rather than lower-grade alloys. This material resists rust, corrosion, and intense heat over long-term outdoor exposure. The burner ring features precision-drilled gas ports engineered to deliver a smooth flame pattern without whistling noise, while integrated weep holes allow rainwater to drain naturally to prevent pooling inside the pan.
Installation is straightforward thanks to the complete drop-in assembly. The unit combines an 18-inch square pan with a pre-installed 12-inch square burner ring, supported by a 1/4-inch outer flange on all sides that rests on the edge of your table cutout. Gas line connection is handled via a standard 1/2-inch center NPT inlet, requiring no welding or intricate assembly work before you hook it up.
Keep in mind that while the burner supports both natural gas and propane, running it on liquid propane requires an air mixer valve that is not included in the package. You will also need to source your own media, such as fire glass, lava rock, or ceramic logs, and maintain at least 2 inches of depth over the burner assembly for proper setup.
Verdict: This drop-in pan is an excellent choice for DIYers building a custom outdoor fire feature who want durable 304 stainless steel and high heat output. It provides a reliable, easy-to-install foundation for both natural gas and propane fire tables.
