See-Thru Vent-Free Gas Burners
Two-sided flames, vent-free (ventless) convenience
Real Fyre see-thru vent-free (ventless) burners are engineered for double-opening fireplaces, delivering a shared flame view without a working chimney. Designed by RH Peterson, these systems are installed in an approved vent-free firebox or a wood-burning fireplace with the damper closed, as allowed by code. When paired with the correct Peterson gas logs or compatible contemporary media, they create a balanced, two-sided presentation with steady, room-warming output.
Purpose-built see-thru series
Real Fyre offers multiple see-thru vent-free platforms to match different aesthetics. The G9 See-Thru is available in 24-inch with an ON/OFF remote control; the G18 See-Thru comes in 16/18-inch and 24-inch sizes and is supplied with a variable-flame remote; and the G21 See-Thru supports contemporary glass or gem media in popular 18-inch and 24-inch sizes. Typical see-thru inputs land in the ~37,000–40,000 BTU range depending on series and size. Choose natural gas or propane per model.
Controls and compatibility
Control options are series-specific to ensure proper performance in a two-sided firebox. G9 See-Thru uses an ON/OFF remote; G18 See-Thru ships with a variable-flame (-15) remote; G21 See-Thru models offer controls matched to their media configuration. Always verify the burner’s supported control type, log/media pairing, and required clearances before purchase.
