Do ventless gas logs work at high elevations, or are they restricted above a certain altitude?
Out in Mills River, where many homes run on propane, ventless gas logs work without any altitude worry — at roughly 2,096 feet you're one of the lower-elevation towns we serve, thousands of feet under the 4,500-foot ceiling. On propane, though, a vent-free set has to carry the correct orifice and regulator pressure, or it burns dirty and soots.
Getting propane vent-free right
Propane burns hotter per unit than natural gas and needs different orifices and pressures, so a vent-free set has to be built or converted for LP and set up to spec. Done correctly, its ODS pilot works exactly as intended at Mills River's elevation. Done wrong — the classic mismatched-fuel install — it soots the logs and burns unclean. Matching appliance to fuel is part of a licensed install.
Room size and moisture still apply
Altitude gives you no trouble here, but two limits do: vent-free sets are restricted from bedrooms and bathrooms in North Carolina, and each one must be sized to the room so it isn't oversized. Vent-free also adds moisture to the air. For a bedroom or a humidity-free option, a sealed direct-vent unit like the propane-ready Kozy Heat Springfield 36 is the better fit.
Coordinated with your propane supplier
We handle the regulator, piping, and appliance setup and coordinate the tank with your propane supplier — all permitted with Henderson County and pressure-tested, because connecting fuel is licensed work a showroom can't do. Mills River's open valley is also great outdoor-living country if you're weighing a gas fire pit. We're 25 minutes south; call (828) 545-0525.
