Outdoor GreatRoom Crystal Fire Plus DIY Gas Burner Kit, 42" Square

The Outdoor GreatRoom Company Crystal Fire Plus DIY Burner Kit measures 42" x 42" and delivers up to 106,000 BTU on natural gas (105,000 BTU on propane) — enough heat output to make a substantial fire pit the undisputed centerpiece of any outdoor space. It's built for those who want to design and construct their own fire feature without sourcing components piecemeal or hoping disparate parts play nicely together.

The kit arrives configured for liquid propane and includes a natural gas conversion kit, so fuel flexibility is built in from the start. The stainless steel construction is well-suited for outdoor installation, and at 96 lbs the complete kit has the kind of heft that suggests it means business. Every core component you need to get the burner functional is included: the Crystal Fire Plus burner insert (BI28), the 42" square burner plate (BP42S), a control panel (VSCV-DIY-CP), two vent blocks, and clear tempered glass gems for that clean, modern fire aesthetic.

Ignition is manual push-button as standard — straightforward and reliable. If you'd prefer the convenience of a Direct Spark Ignition system, that upgrade is available separately. The natural gas inlet pressure range is 3.5" to 10.5" WC; propane runs between 8" and 14" WC. The valve is manual, keeping operation intuitive and the system simple.

The kit is UL Listed, which matters both for peace of mind and for satisfying local permitting requirements — a detail worth noting before the concrete gets poured. Pavers, construction materials, decorative burner media beyond the included glass gems, and other accessories are sold separately, giving you full control over the finished look without being locked into a single aesthetic.

This is a purpose-built kit for a purpose-built project. If you have a specific fire pit design in mind and the patience to construct it properly, the Crystal Fire Plus 42" Square DIY Kit provides the mechanical and functional core to make it happen at a scale and output level that doesn't disappoint.
