Review: Well made. Works great. - I bought this in used but excellent condition. Like some other reviews, the packaging does seem to be insufficient as it arrived with one of the corners substantially bent upward. I was able to bend this back to almost unnoticeable condition. I expected something like this as I purchased it in used condition, so no big deal. As for the pan and burner, they are well made and the dimensions were spot on. We were converting a DIY wood firepit to propane and this fit perfectly and works perfectly. We also purchased the Onlyfire control box and an extra long (18 foot) propane line and both items fit and worked perfectly for our application. We are very happy with this purchase and now we can enjoy a nice relaxing fire with no fuss and no more smelling like smoke. The one thing I will say is that because this is such a large burner it does seem like we will be going through a good amount of propane, so be aware of this when choosing the size pan/burner combo for your project if you have that flexibility. We anticipated this, so not a problem for us.
Review: An excellent stainless steel fire pit pan and burner assembly - An extremely well crafted stainless steel replacement pan and burner assembly for my fire pit table which had rusted out after one season of frequent use. The original pan and burner assembly was not stainless steel. The replacement unit had a generous lip and very neat welds.

## Features

- 【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, you get more fire, more heat, less waste. (Fact: 30" square burner = 900 sq in vs 30" round = 707 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 inside the pan. This insert is made to last through seasons of backyard enjoyment – even in coastal or humid environments.
- 【Complete Drop-in Assembly – Ready for DIY Installation】 - Includes 36" square pan with 30" 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】 - Delivers massive 435,000 BTU – enough to warm large patios, poolside lounges, or commercial outdoor areas. Works with both natural gas and propane (air mixer required for propane – sold separately). Compatible with fire glass, lava rock, or ceramic logs (minimum 2" depth recommended; up to 130 lbs of fire glass).
- 【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 that stands out in any outdoor space. Perfect for large backyard fire tables, outdoor kitchens, or commercial patios. Upgrade your outdoor living area with a professional-grade fire feature.
- 【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 igniter ot 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.

### ⭐⭐⭐⭐⭐ Great Fire Pit
*by R***Z on August 28, 2020*

Really nice stainless steel fire pit. I bought the 36” pan. Nice flame and overall good build quality for the price. My one complaint is it only has a 1/2” inlet when it claims to be rated for 400 thousand plus btu but only at 0.5 psi. It’s pretty hard to find the fittings needed if using a turn valve to get over 300 thousand btu. Regardless it’s still really nice and very warm.
