24" G21 Vent-Free Glass Burner LP

Some fireplaces are built for warmth. Some are built to impress. The Real Fyre 24" G21 Vent-Free Glass Burner (LP, SKU: G21-GL-24-12P) insists on doing both — and doing them exceptionally well.

Engineered from durable 304 stainless steel and rated at 30,000 BTU/hr on propane/LP, this burner delivers genuine, room-filling heat without the need for a vent or chimney. Whether you're retrofitting an existing firebox or designing a new feature wall, the G21 offers versatile certification for both unvented room heater and vented decorative appliance applications — so your design vision doesn't have to compromise with your installation reality.

The visual centerpiece of this system is, of course, the glass media. Paired with Real Fyre's own Fyre Glass or Fyre Gems (10 lbs required, sold separately in your choice of colors), the G21 transforms your firebox into a luminous showcase of dancing flame and richly colored reflections. It's the kind of fire feature that stops conversation — briefly — while guests simply stare.

Control is handled by the included 12 Series Standing Pilot system with On/Off Remote, making it easy to ignite ambiance from across the room without leaving your favorite chair. Safety is equally considered: a built-in Oxygen Depletion Sensor (ODS) continuously monitors room air quality and automatically shuts the burner down if oxygen levels drop below safe thresholds. Because great design and peace of mind should always come as a package.

The G21 is certified to ANSI Z21.11.2-2013 as an unvented room heater and ANSI Z21.60-2012 as a vented decorative appliance, ensuring compliance with industry safety standards. At 24 inches wide with a front-to-back burner depth of 10.5 inches, it is engineered for fireboxes with a minimum front width of 28 inches, rear width of 21 inches, depth of 13 inches, and height of 17 inches — so be sure to confirm your firebox dimensions before ordering.

As a complete Real Fyre ecosystem product, this burner is listed and warranted exclusively for use with Real Fyre gas logs, valves, controls, and accessories. Only Peterson Real Fyre glass and gems are certified for use with this burner. Mixing components from other sources isn't just inadvisable — it voids the warranty and compromises the safety certifications that make this system worth owning.

At $1,835.00, the Real Fyre G21 represents a premium investment in the art of the fireplace — one that pays dividends in beauty, warmth, and the quiet satisfaction of doing things the right way.
