Frequently Asked Questions

  • The Grand Canyon Outdoor Round Flat Stack Gas Log Burner is available in five diameters — 18", 24", 30", 36", and 48" — and each size represents the minimum fire pit opening required for installation. You should match the burner size to your fire pit's interior opening, ensuring it meets or exceeds the listed minimum dimension. It works equally well for replacing an existing burner or outfitting a newly built round gas fire pit.

  • Yes, the burner is available in both Natural Gas (NG) and Liquid Propane (LP) configurations. LP models include a conversion kit and a flat stainless steel disc in the box. You should select your fuel type at the time of purchase, as natural gas and LP models are not interchangeable — the gas type is indicated on both the burner itself and the packaging.

  • The Grand Canyon Outdoor Round Flat Stack Burner comes in two ignition options: match-lit or the WBECS 12V Weather Beater Electronic Ignition System. If you choose the electronic ignition option, be aware that it requires 120 volts of power to be run to the fire pit for the valve to operate. The Weather Beater system is designed for all-weather durability and can be controlled remotely for added convenience.

  • Because this is an outdoor-specific burner made of 100% stainless steel, it carries a lifetime warranty against manufacturer defects or breakage when installed outside. The decorative logs installed outdoors carry a 5-year warranty, while the electrical components, valves, and receivers are covered for 2 years from the date of purchase by the original purchaser. To keep the warranty valid, the system must be installed by an NFI-certified or other qualified professional, and only Grand Canyon Gas Logs parts and accessories may be used.

  • No, the decorative logs are sold separately and are not included with the burner kit. The kit itself includes the Round Flat Stack Burner, a fittings installation kit (1/2" for 24" and 30" models; 3/4" for 36" and 48" models), lava rocks, an LP conversion kit (LP models only), a flat stainless steel disc (LP and electronic ignition models), the Weather Beater Electronic Control System (electronic ignition models only), and a user's manual. Compatible log styles available for purchase include Arizona Weathered Oak, Aspen, and Western Driftwood.
