Warming Trends Authorized Dealer | Flame Authority - Trusted Dealer

The Warming Trends CFB120 Fire Pit Kit is a premium, ready-to-customize outdoor fire feature system that combines professional-grade performance with flexible installation. At its core is the CFB120 Original Brass Crossfire® Burner, delivering up to 120,000 BTUs for bold, natural-looking flames that mimic the look of wood but with the clean efficiency of gas. Made entirely from 100% corrosion-resistant brass, the burner features WATERSTOP® technology to prevent water intrusion into the gas line—ensuring year-round reliability and safety.

The kit includes a 36” x 36” wide, 18” high aluminum frame enclosure pre-wrapped in concrete board, allowing you to easily finish the exterior with your choice of stone, tile, or stucco. Inside sits a 24” aluminum drop-in burner pan with 2” sidewalls, built to securely hold the burner, support fire media like lava rock or glass, and manage ventilation and heat distribution.

To support safety and proper airflow, a Fire Pit Vent Kit is included, along with the FK1 manual spark ignition system for quick, match-free lighting. A 4” key valve extension provides external access for flame adjustment and gas shutoff, and the system includes components for use with both natural gas and propane, giving you installation flexibility.

Perfect for both residential and commercial spaces, this kit delivers powerful flames, smooth ignition, and dependable all-weather performance—all in a durable, customizable design.
