Outdoor GreatRoom Crystal Fire Plus Square Burner Insert & Plate Kit, 42"

At 42" x 42" and 150,000 BTU, the Outdoor GreatRoom Crystal Fire Plus Square Burner Insert and Plate Kit isn't shy about what it's built for. This is a commercial-grade fire source engineered to anchor a serious outdoor fire feature — whether that's an OGC fire table fresh from the showroom or a custom masonry build you've been planning since last winter.

The kit pairs a direct spark ignition (DSI) burner insert with a matching burner plate in an undermount configuration, meaning the hardware disappears below the surface and what you see is clean, uninterrupted fire. No exposed hardware, no improvised workarounds — just a properly installed flame that looks intentional because it is.

At 14.66" in height, the kit fits within standard fire pit table cavities while leaving room for up to 90 pounds of fire media on top. That's enough lava rock, fire glass, or decorative stones to create a genuinely substantial media bed — the kind that looks like someone actually thought about it, rather than a sparse handful scattered over a bare burner.

The Crystal Fire Plus line carries both UL and ULC listings, which matters for two reasons: insurance underwriters tend to appreciate it, and it means the burner has been independently tested to meet established safety standards — not just certified by the manufacturer's optimism. It's compatible with all Outdoor GreatRoom Company fire pit tables and fire pits, and equally at home in a custom-built outdoor fire feature.

Direct spark ignition means no pilot light to babysit and no manual lighting required. The ignition system fires on demand, which is exactly what you want when guests are already seated and someone asks why the fire isn't on yet.

This SKU is configured for liquid propane (LP). Confirm your gas supply type before ordering, and verify that your fire pit cavity accommodates the 42" x 42" footprint and 14.66" height clearance.
