Real Fyre G23 Vent-Free Fyre Spheres Burner
Real FyreReal Fyre G23 Fyre Spheres Burner Overview
The Real Fyre G23 is RH Peterson's contemporary spheres-only burner, engineered specifically for the Fyre Spheres media collection. Unlike the glass-and-gems G21, the G23 burner features pegged sphere mounts that hold each 4-inch sphere in position over the burner ports, creating tall flames that wrap around the spheres for a sculptural fire presentation. Available in 18-inch and 24-inch sizes, the G23 produces 28,000 BTU at 18-inch and 37,000 BTU at 24-inch (NG and LP equal).
For 2026, RH Peterson introduces the new Nero Marquina sphere finish - a deep black surface with white veining inspired by the Spanish marble of the same name - joining the existing Carrera Marble (white with gray veining), Epic Black (matte black), and Gray Stone (textured concrete-look) options. Two control levels are offered: ON/OFF remote (-12) and the electronic-pilot variable flame remote (-01V) for full ambiance control. The G23 ships with a removable front panel, connector kit, and ODS-equipped pilot system; black glass media for the firebox floor is included with the burner.
