Outdoor GreatRoom Crystal Fire Plus DIY Burner Kit, 24" Square

The Crystal Fire Plus BP24S-A burner insert sits at the center of this kit, and it sets the standard for what a custom fire pit insert should be. Rated at 55,000 BTUs on both liquid propane and natural gas, it delivers a consistent, full flame across the entire 24" x 24" burner surface — the kind of output that makes a fire pit feel intentional rather than incidental.

Commercial-grade #304 stainless steel construction means this burner is built to stay in whatever you build around it. Corrosion resistance, structural integrity, and long-term performance are baked into the material choice, not added as an afterthought. The cut-out dimensions — 23.69" wide × 23.69" deep × 4.91" tall — are precise enough that planning your paver or masonry surround is straightforward, provided you measure twice.

The kit ships configured for liquid propane, which covers most outdoor installations right out of the box. When natural gas is the better fit for the project, the included conversion kit handles the switch — though the conversion itself should be performed by a certified gas technician. That's not a suggestion so much as a strong recommendation backed by the kit's UL and ULC listing to ANSI Z21.97-2017/CSA 2.41-2017.

Ignition is handled by a push-button piezo system with manual control. No batteries, no Bluetooth pairing, no firmware updates — just a reliable mechanical spark when you want a fire. For those who prefer electronic ignition, compatible upgrade systems are available separately.

Every component needed to get the burner installed and operational is included: the Crystal Fire Plus burner insert, burner plate, control panel, vent blocks, and 24 lbs of clear tempered glass gems. The glass coverage alone represents a meaningful portion of the finished look — clear gems catch and scatter flame in ways that solid media simply don't.

This kit is designed specifically for custom construction with brick pavers or comparable materials, and it's fully compatible with other Outdoor GreatRoom DIY square burner components and accessories. If the project calls for expanded media, upgraded controls, or additional accessories down the line, the platform supports it. Build it once, build it right.
