24" G21 VF See-Thru Glass Burner NG

Some fireplaces demand to be seen from one side. The Real Fyre 24" G21 See-Thru Vent-Free Glass Burner insists on being admired from two. Designed for open, double-sided fireboxes, this contemporary burner transforms a shared wall or room divider into a luminous centerpiece that works as hard on ambiance as it does on warmth.

Built entirely from 304 stainless steel with a polished mirror finish, the G21 is as beautiful in construction as it is in performance. This isn't a burner that hides behind its media — it's engineered to complement the shimmering display of Real Fyre Fyre Glass or Fyre Gems (sold separately), creating a sophisticated, modern fire presentation unlike anything a traditional log set can offer.

At 40,000 BTUs and a remarkable 99% heating efficiency, this burner doesn't just look the part — it delivers serious, room-filling warmth. Whether you're running it on natural gas or propane, performance remains consistent and powerful, making it a practical heating solution as well as an undeniable design statement.

Safety is built into every flame. The integrated Oxygen Depletion System (ODS) pilot continuously monitors room oxygen levels and automatically shuts the burner down if levels drop below safe thresholds — giving you peace of mind along with a beautiful fire. ANSI Z21.60 certified for both natural gas and propane, the G21 meets rigorous North American safety standards.

Convenience comes standard with the included On/Off remote control system, so you can ignite, enjoy, and extinguish your fire from the comfort of your favorite chair. The piezo ignition means no fumbling for matches or lighters — just a clean, reliable start every time.

Installation requires a firebox with minimum dimensions of 28" (front width) × 16" (depth) × 17" (height), and the system requires approximately 12.5 lbs of Real Fyre Fyre Glass or Fyre Gems to complete the look. Please note: only Peterson Real Fyre-approved glass and gems are certified for use with this burner — a small but important detail that protects both your investment and your warranty.

Compatible as either a vent-free or vented appliance depending on your local building codes, the G21 offers flexibility that most contemporary burners simply can't match. Whether you're designing a new build or upgrading an existing fireplace, this burner is the kind of finishing touch that elevates an entire space.

At $2,138.00, the Real Fyre 24" G21 See-Thru Glass Burner represents a premium investment in year-round beauty and dependable warmth. After all, a fireplace this refined isn't just a heat source — it's the conversation starter that never gets old, no matter which side of the room you're standing on.
