Is converting a wood-burning fireplace to gas safe?
Yes — done by a licensed gas contractor, a wood-to-gas conversion is one of the safest upgrades a fireplace can get: a sealed insert vents through its own new liner, a vented log set gets the damper clamped open, and the gas line is permitted and pressure-tested. What's not safe is the shortcut version — an unlicensed line, no permit, no damper clamp, wrong orifices for the fuel.
Two paths, two safety profiles
A conversion goes one of two ways. Vented gas logs keep the open-fireplace look — tall yellow flame, damper permanently clamped open so combustion byproducts always have an exit. They're ambiance-first, and honestly most of the heat goes up the chimney, but the safety model is simple and proven. A sealed gas insert is the other path: its own stainless liner runs up the old flue, combustion is sealed away from your room air, and you get real, efficient heat — with millivolt or battery-backup ignition, heat that still works when the power doesn't. Both are safe when done to the book; the full walkthrough is in our guide at /guides/convert-wood-fireplace-to-gas.
Where conversions actually go wrong
Every bad conversion we've been called to rescue shares the same DNA: gas work done by whoever was handy. The classics are an unpermitted line teed off somewhere it shouldn't be, no damper clamp on vented logs — which lets someone close the damper on a burning set — and fuel mismatch. That last one is a WNC special: natural gas runs along the Asheville and Hendersonville mains, but out in Fairview, Candler, Brevard, and the cabins it's propane, which burns hotter and needs different orifices and pressures. A set jetted for the wrong fuel soots, and soot is the polite warning.
The license is the whole ballgame
In North Carolina, running or extending a gas line is licensed work — a showroom or a mason can sell you a beautiful firebox, but they legally can't connect it to fuel. We can, and we permit and pressure-test every line we run: permit pulled with your county — Buncombe, Henderson, Haywood, or Transylvania — inspector met, paperwork done. That permit protects your homeowner's insurance and your future home sale. Call (828) 545-0525 for a free in-home assessment and we'll tell you which path fits your fireplace.
