Crystal Fire Plus Square Gas Burner Insert and Plate Kit

The Perfect Drop-In Burner Kit for Custom Fire Pits & Fire Pit Tables

The Crystal Fire® Plus Square Gas Burner Insert and Plate Kit is engineered for builders, designers, and homeowners who want a seamless, professional-grade fire feature without compromise. Featuring a no-flange edge and undermount installation, the burner plate disappears beneath a bed of tempered fire glass gems — leaving nothing but a breathtaking, full-height flame as the focal point of your fire pit or fire pit table.

Whether you're building a custom backyard fire pit from scratch or upgrading an existing outdoor fire feature, this kit gives you everything you need to create a stunning result. The clean-burning flame rises tall and bright over shimmering fire glass, and with your choice of ignition, starting your fire is as simple as a push of a button or a turn of a valve. Choose manual push-button ignition for simple, reliable operation with no electricity required, or upgrade to electronic ignition (DSI) for instant one-touch convenience — both available in Liquid Propane and Natural Gas configurations.

The undermount design hides all hardware for a clean, finished look in any fire pit or fire pit table. Adjust the flame height to set the perfect mood, and let the included tempered fire glass gems complete the polished, resort-style finish. Available in four square sizes — 24" x 24", 30" x 30", 36" x 36", and 42" x 42" — this kit fits a wide range of fire pit table designs and custom outdoor fire feature builds.

For design professionals and landscape architects, the no-flange undermount design integrates cleanly into concrete, stone, steel, or any custom surround.  The Crystal Fire Plus burner plate/insert delivers a brighter, taller, fuller flame, and stainless steel construction ensures long-term outdoor durability. With four square sizes and flexible fuel and ignition options, this burner kit accommodates a wide range of fire pit table and landscape fire feature specifications.
