24/30" G18 Vent-Free Burner, Manual, NG

Some fireplaces are born great. Others achieve greatness with the right burner system. The Real Fyre 24/30" G18 Vent-Free Gas Burner (Manual, Natural Gas) is precisely that upgrade — a thoughtfully engineered, ANSI-certified vent-free burner that transforms a cold, idle firebox into a genuine heat source you'll actually want to use on a winter evening.

At its core, the G18 system is designed for straightforward, dependable performance. On the high setting, it delivers a robust 38,000 BTU, while the low setting pulls back to a gentler 25,000 BTU — giving you real flexibility between "take the chill off" and "this room is now legitimately cozy." The manual safety pilot control keeps operation intuitive: no apps, no remotes, no batteries required. Just classic, hands-on flame management.

Because this is a vent-free system, no chimney or flue is needed to operate it — but peace of mind is still very much included. The built-in Oxygen Depletion Sensor (ODS) pilot system continuously monitors the room's oxygen levels and will automatically shut the burner off if levels drop below a safe threshold. It's the kind of safety feature that works quietly in the background, which is exactly where safety features belong.

Installation is compatible with solid-fuel-burning masonry fireplaces, UL 127 factory-built fireplaces, or a listed ventless firebox enclosure. The system accommodates 24" log sets in fireplaces with a minimum 30" width, or 30" log sets in fireplaces with a minimum 36" width. Minimum depth and height requirements are 24" and 14" respectively, with a rear fireplace height of 17". It's worth taking those measurements before you order — your fireplace has opinions about what fits inside it.

The G18-24/30 is certified to ANSI Z21.11.2 (Unvented) and ANSI Z21.60 (Vented) standards, reflecting Real Fyre's commitment to quality and safety that goes well beyond the basics. At 27 lbs, it's a solid, well-built unit that installs with confidence.

This burner is compatible with Real Fyre's Evening Fyre, Evening Fyre Charred, and Evening Fyre Split log sets, which are available separately and complete the look of a natural wood-burning fire. For controls and accessories, only Peterson Real Fyre components specifically listed or certified for use with this system should be used — quality is only as strong as its weakest link.

Whether you're upgrading an existing fireplace or outfitting a new build, the Real Fyre G18 Vent-Free Burner is a premium foundation for a hearth that earns its place in your home every single season.
