Complete Vent-Free Sphere Sets

Modern design, vent-free (ventless) simplicity

Real Fyre complete vent-free (ventless) sphere sets deliver a contemporary, sculptural look where a chimney isn’t practical. Built around the G23 Series vent-free burner, these all-in-one packages pair pinned 4-inch Fyre Spheres with a tuned burner for tall, lively flames and a clean presentation — installed in an approved vent-free firebox or a wood-burning fireplace with the damper closed, as allowed by local code. Crafted by RH Peterson, they’re authentic RH Peterson gas logs alternatives with modern media.

All-in-one convenience, verified finishes

Each G23 complete set includes the vent-free burner, the matching ceramic spheres, an Oxygen Depletion Sensor (ODS), a removable front panel for easy access, and a connector kit — the right pieces for a ready-to-install system. Choose proven finishes such as Epic Black, Carrera Marble, and Graystone in popular 18-inch and 24-inch sizes with typical inputs spanning about 28,000–37,000 BTU. Models are available for both natural gas and propane, depending on the configuration.

Control options that match the burner

G23 vent-free sphere sets offer Remote ON/OFF (-12) with optional Bluetooth ON/OFF (compatible with the -12 valve), or variable-flame electronic ignition (-01V). Pick the control your specific burner/size supports for the experience you want.
