16/18" G18 Vent-Free Burner, Variable

Some things in life deserve a second act — and if your existing vent-free fireplace is ready for one, the Real Fyre 16/18" G18 Vent-Free Variable Burner System is the upgrade it's been waiting for. Engineered to deliver serious warmth with refined, hands-free convenience, this millivolt burner system is the heart of a truly premium hearth experience.

At its core, the G18 outputs between 22,000 and 30,000 BTU on both natural gas and propane, giving your space the kind of heat that makes you wonder why you ever wore slippers. But it's not just about raw output — the variable flame height remote control lets you dial in the perfect ambiance from across the room, while the piezo igniter means reliable, tool-free lighting every time.

Safety is never an afterthought here. The Oxygen Depletion Sensor (ODS) pilot system continuously monitors room oxygen levels and automatically shuts down the burner if levels drop below safe thresholds — a critical safeguard for any vent-free appliance. Add in ANSI certification, and you can feel confident this system meets the industry's highest standards for safety and performance.

Installation is straightforward when your fireplace meets the minimum requirements: 22" width, 20" depth, 14" height, and 17" rear depth. The included 30-inch connector kit gets you set up quickly, and the package also arrives with lava granules, embers, Bryte Coals, and glowing embers — so the finishing touches are already taken care of.

The G18 is designed exclusively for use with Real Fyre 16/18" Evening Fyre log sets, including the Evening Fyre (EFV-16/18), Evening Fyre Split (ESV-16/18), and Evening Fyre Charred (ECV-16/18). For safe operation and to maintain warranty coverage, only Peterson Real Fyre controls, parts, and accessories certified for use with this system should be used — compatibility done right, not left to chance.

Remote operation requires a 12V battery for the transmitter and 4 AA batteries for the receiver (batteries not included, because you probably have a junk drawer full of them). At 24 lbs, this burner system is built with the substance you'd expect from a premium hearth component.

Confidence in your purchase comes built-in: the burner itself carries a 10-year warranty, while controls and valves are covered by a 1-year limited warranty. Real Fyre has been a trusted name in hearth craftsmanship for decades, and the G18 reflects that legacy at every detail.

Whether you're replacing an aging burner or building a new vent-free log set from the ground up, the Real Fyre G18 Variable Burner System delivers the performance, safety, and sophistication your fireplace deserves.
