Outdoor GreatRoom Crystal Fire Plus DIY Burner Kit, 42" Round

At 106,000 BTU on natural gas (105,000 on LP), the Outdoor GreatRoom Company Crystal Fire Plus 42-inch Round DIY Burner Kit is not shy about its output. This is the hardware backbone for a serious custom fire pit build — a complete, UL Listed burner system in 304-grade stainless steel that arrives ready to drop into your own masonry, concrete, or fabricated fire pit table design.

The kit ships configured for liquid propane right out of the box, and the natural gas conversion kit is included in the package — no separate purchase, no scrambling. Whichever fuel source your project calls for, you're covered before you even break ground.

What's in the box matters here, so let's be specific: you get the Crystal Fire Plus burner insert, a burner plate, a control panel, vent blocks (two included), and clear tempered glass gems for media. It's a well-considered assembly of the core components that make a fire feature actually function — and function well. Pavers, construction materials, additional burner media, and decorative accessories are sold separately, giving you full creative control over the finished look without paying for materials you may not want.

Ignition comes in two flavors: manual push-button for those who appreciate simplicity, or electronic ignition for a more refined lighting experience. Both are solid options depending on how your installation is designed and how much you enjoy pushing buttons in the dark.

The 42-inch round footprint is a substantial size — well suited to a fire pit table or a larger freestanding outdoor hearth feature where presence and warmth coverage are priorities. At this diameter, the Crystal Fire Plus insert produces a flame display that earns its square footage.

UL Listed certification means this kit has been independently tested and verified to meet safety standards — not just a manufacturer's claim, but third-party validation. That matters when you're building a permanent fire feature into a custom structure.

If you're designing a custom outdoor fire feature from the ground up, this kit provides the proven, high-output core system. What you build around it is entirely up to you.
