The CROSSFIRE® design uses patented flame technology to mix fuel with oxygen at the jet level, producing flames twice as tall and twice as full as conventional burners while using half the gas.
Every burner is forged from solid brass, the same material used in premium plumbing and marine hardware. It won't rust, won't corrode, and won't fail. Backed by an industry-leading lifetime warranty.
Ships with sealed adapters for both natural gas and liquid propane standard. No extra parts, no reorders, no guesswork.
Every burner includes Warming Trends' WATERSTOP™ fitting, protecting gas lines from water and debris and allowing the burner to self-purge when lit. Built for all climates, all seasons.
Engineered internal architecture eliminates the whistling and roaring common in high-output burners. Powerful heat output, zero noise distraction.
Designed, engineered, and assembled in Denver, Colorado. Every CROSSFIRE® 2.0 burner is CSA/ANSI certified for outdoor fire features and fireplaces.
