What's the difference between ventless gas logs and a dedicated ventless gas fireplace?
Ventless gas logs are a burner-and-log kit that installs inside a fireplace you already have, burning with the damper closed. A dedicated ventless gas fireplace is a complete self-contained appliance — firebox, burner, and cabinet — that can be framed into a wall that never had a fireplace or chimney at all. Same combustion rules, very different starting points.
Logs go in a firebox you already own
A ventless log set is the retrofit path. If you have an existing masonry or approved firebox — usually an old wood-burner you're tired of feeding — we run the gas line, set the burner and logs, and the damper stays closed so the heat stays in the room. It's the quickest, least invasive way to turn a dormant fireplace into a working heater, and we do a steady stream of these conversions in older Asheville and Hendersonville homes where the chimney has seen better days.
A dedicated vent-free fireplace starts from a blank wall
The dedicated unit is a full appliance with its own firebox, designed to be framed into new construction, an addition, or a wall in a room that has never had a hearth — no chimney, no flue, no exterior penetration at all. Superior's 36-inch vent-free fireplace is the one we lean on: 40,000 BTU, and a millivolt ignition that needs no electricity, which means it keeps heating when the grid goes down — a feature nobody in WNC has taken for granted since Helene.
What they share, and how to pick
Everything that defines vent-free applies to both: an ODS oxygen sensor, Btu limits tied to room size, added indoor moisture, and restrictions in bedrooms and bathrooms in many jurisdictions. Both also require a licensed gas connection — in North Carolina that's the law, and it's our lane. The choice usually makes itself: existing fireplace, use logs; blank wall, use the dedicated unit — or consider a direct-vent fireplace, which vents out a sidewall and drops the vent-free rulebook entirely.
