18" G21 Vent-Free Glass Burner LP

Some fireplaces demand a centerpiece worthy of the room they anchor. The Real Fyre 18" G21 Vent-Free Glass Burner (LP) is exactly that — a precision-engineered, stainless steel burner system that transforms your hearth into a luminous showcase of dancing flame and glittering glass media.

Built from durable 304 stainless steel, the G21 is designed for longevity and consistent performance in a vent-free application. At 27,000 BTU on propane, it delivers serious, room-warming heat output without requiring a flue or chimney — making it an elegant and practical solution for a wide range of fireplace settings.

The real showstopper, of course, is what surrounds the flame. This burner is engineered exclusively for use with Real Fyre Fyre Glass or Fyre Gems (7.5 lbs required), whose jewel-like facets catch and scatter firelight in ways that traditional gas logs simply cannot. The result is a contemporary, upscale aesthetic that never grows old — whether you're entertaining guests or simply unwinding at the end of a long day.

Convenience is baked into every detail. Electronic/Piezo ignition means no matches, no fuss, and no fumbling in the dark. The included On/Off remote control (12 series standing pilot) lets you ignite, adjust, and extinguish your fire from the comfort of your sofa — because getting up shouldn't be a requirement for good ambiance.

Safety is never an afterthought here. The built-in Oxygen Depletion Sensor (ODS) continuously monitors ambient oxygen levels and automatically shuts the burner off if they drop below safe thresholds — giving you peace of mind alongside that beautiful glow.

At 10.5 inches front-to-back and an 18-inch profile, the G21 is sized to fit a range of firebox configurations. Installation requires 16 inches of clearance from combustible sidewalls and 42 inches of clearance from the fireplace opening top — please verify your fireplace dimensions prior to purchase to ensure a proper, safe fit.

A note on compatibility: the G21 is engineered and listed exclusively for use with Real Fyre gas logs, valves, controls, and accessories. Mixing with other brands is not recommended and will void the product's listing and safety certifications. When a system is this thoughtfully designed, it's best to keep it in the family.

At $1,702.00, the Real Fyre G21 represents a genuine investment in the comfort, beauty, and value of your home. For those who believe a fireplace should be more than a heat source — that it should be an experience — this is the burner worth having.
