Innovation. Design. Performance. The Crossfire® Brass Burner by Warming Trends® is a distinctive fire pit burner that utilizes cutting-edge technology to produce a taller, brighter, fuller flame. Leading the industry with a highly engineered, precision product, Warming Trends® is the original and only manufacturer of the Crossfire® Brass Burner.

Our Four Pillars

The patented technology behind our Crossfire® Brass Burner uses a specific air-to-gas ratio at the point of combustion to produce a taller, brighter, fuller flame that resembles a natural, wood-burning fire. We call this the Venturi Effect. Venturi Jet Technology generates high-velocity gas flow and pulls more oxygen into the jet chamber – feeding the combination into the flame at the point of combustion. This causes the gas and oxygen mixture to shoot out of the jet at a high velocity as a super-charged flame, like water out of a fire hose.  

Twice the Flame


 All parts and pieces of the Crossfire® Burner are made from brass. Unlike other burners made from stainless steel; brass is corrosion resistant and will not rust, which eliminates the need for replacement. We're so confident the product will last, we offer a lifetime warranty on all brass products.


All Brass Components

We stand behind our products and construction. Corrosion-resistant, Sustainable, and rust-proof, brass allows to offer the strongest lifetime warranty in the industry.
