onlyfire 36 Inch Square Fire Pit Burner Ring for Natural Gas & Propane, 304 Stainless Steel DIY Firepit Burner for Fire Pit & Fireplace, Indoor Outdoor Use, Whistle-Free, 443,000 BTU

• 【Exclusive Square Design – Full Corner-to-Corner Flame Coverage】 – Unlike round burners that leave cold spots in square or rectangular fire pits, our concentric square burner ring delivers flames into every corner. Engineered for angular fire pits with inner dimensions at least 6 inches larger than the burner side length, it maximizes heat distribution and creates a stunning geometric flame pattern. Perfect for modern outdoor spaces.
• 【Sizing Guide – Choose the Right Burner】 – To achieve optimal flame coverage and safe operation, select a burner with side length at least 6" smaller than your fire pit (pan)’s inner width. For example: 36" burner → fits 42"+ pits; 30" burner → fits 36"+ pits; 18" burner → fits 24"+ pits. This ensures proper clearance for gas lines, fire glass, and lava rock while maintaining balanced airflow and flame height. Please measure your fire pit’s interior dimensions before ordering.
• 【Heavy-Duty 304 Stainless Steel – Built to Last】 – Crafted from thickened 304 stainless steel pipes—42% thicker than standard burners—this square fire ring withstands extreme heat (rated up to 443,000 BTU) and years of outdoor exposure without rust or warping. Welded construction ensures structural integrity for the unique square design, maintaining safe, stable flame distribution season after season. Whether used indoors or outdoors, this burner delivers reliable performance.
• 【Whistle-Free Operation – Laser-Drilled Precision】 – Every flame hole is laser-drilled, not punched, to eliminate sharp edges that cause turbulent airflow and annoying whistling sounds. This precision engineering, combined with the concentric square design’s balanced gas distribution, ensures a quiet, peaceful ambiance. Perfect for intimate gatherings or relaxing evenings where you want the warmth of a fire without distracting noise.
• 【Dual-Fuel Versatility – Indoor & Outdoor Ready】 – Compatible with both natural gas and propane (propane requires an air mixer, sold separately), this burner adapts to your fuel preference and setup. Ideal for patios, gardens, modern indoor fireplaces, or custom DIY fire pit projects. The square flame pattern complements angular seating arrangements, providing even heat distribution and a striking visual centerpiece for any entertaining space.
• 【Note】 – For large-sized burners, sometimes there may be no flame at the outer gas outlets, but this does not mean the burner itself is damaged. In such cases, you can try using an ignition gun to externally assist in igniting these outlets. The reason is that each outlet requires a sufficient concentration of propane or natural gas to ignite automatically, and it takes longer for the gas to reach the outer outlets.
