Outdoor GreatRoom Crystal Fire Plus Round Gas Burner Insert, 36"

At 36 inches across and rated at up to 106,000 BTU on natural gas (105,000 BTU on liquid propane), the Outdoor GreatRoom Crystal Fire Plus Round Burner Insert is built for fire tables and outdoor installations where a commanding circular flame is the entire point. This isn't a burner that hides in the background.

The insert itself is stainless steel construction and weighs in at 29.9 lbs — substantial enough to feel serious, manageable enough that installation doesn't require a crew. Speaking of installation: this is an undermount unit, designed to drop into your fire table or enclosure from below, with a maximum wall thickness of 5.5 inches and a minimum support requirement of just 1 inch. The control panel needs to land within 30 inches of the electrode, so plan your enclosure layout accordingly before cutting anything.

Ignition is manual, keeping the system straightforward and reliable without the added complexity of electronic components exposed to the elements. The burner ships standard for liquid propane, with a conversion option available for natural gas — so if your installation site has a dedicated gas line, you're covered either way.

The Crystal Fire Plus system is compatible with the Variable Control Safety Valve (VCSV), which gives you genuine flame adjustment rather than a binary on/off situation. That level of control matters when you're hosting and the mood calls for something between "roaring bonfire" and "barely there glow." The burner plate kit supports up to 50 lbs of fire media — whether you're working with glass, lava rock, or other approved media is a conversation for your specific media of choice, but the weight capacity gives you meaningful flexibility in your design.

For the gas supply connection, compatible flex-line options are available in four lengths: 16 inch (PT# T200-9898-16), 22 inch (PT# T200-9898-22), 34 inch (PT# T200-9898-34), and 46 inch (PT# T200-9898-46), accommodating different enclosure depths and valve configurations without improvised workarounds.

At $1,249.00, this is a component purchase for a builder, designer, or serious DIYer who knows exactly what they're constructing. The 36-inch round format is a deliberate choice — circular flames read differently than linear ones, centering the fire visually in a way that works especially well for round or square table formats where everyone gathered around has an equally good seat.
