Warming Trends Crossfire 360K BTU Universal Burner — 29.5" x 28.5" Brass Burner with 42" Round Plate & Flex Line Kit

Most fire pit burners give you a flame. The Crossfire gives you a fire.

This is the original CROSSFIRE® Brass Burner from Warming Trends — the patented design that started the category and still leads it. At 360,000 BTU across a massive 29.5" x 28.5" footprint, paired with a 42" round pan, this is the burner for statement-sized fire pits that need to dominate the space, not just fill it.

The Venturi Effect: Why This Flame Looks Different

Every other burner just releases gas. The Crossfire's patented Venturi Jet Technology pulls extra oxygen into the jet chamber at the point of combustion, launching a supercharged mix out at high velocity — like water out of a fire hose instead of a garden hose. The result is a flame that's taller, fuller, and brighter, with the organic movement of a real wood fire instead of the flat blue ring you get from a standard burner.

Guests won't ask what kind of burner you have. They'll just stand closer.

100% Brass. Zero Rust. Zero Excuses.

Every component is solid brass — not stainless, not a brass-coated substitute. Brass doesn't corrode, doesn't rust, and doesn't degrade season after season sitting outside in the elements. That's exactly why Warming Trends backs it with a lifetime warranty on all brass products — they've engineered out the reason most burners eventually need replacing.
