Do I need a high-altitude conversion kit for my gas fireplace, and above what elevation?
Out in Mars Hill's rural Spring Creek and Gabriels Creek valleys, homes often run propane, so the fireplace orifice is propane-sized before altitude even factors in. At 2,350 feet — a colder-than-average spot — some models sit over their listed ceiling and want a manufacturer's adjustment, others don't. We check your specific unit and fuel against the site.
Propane country changes the part twice
A propane fireplace already meters fuel through a smaller orifice than a natural-gas one, and above a model's altitude ceiling the correct orifice changes again — two adjustments we'd rather make in one pass than by pulling the burner apart twice. On the rural valley properties around Mars Hill where propane is the norm, and on the university-area rentals closer to town, we size for the fuel first and layer the high-altitude derate on top only where the manual at 2,350 feet requires it. Mars Hill runs colder than much of the area, so a flame that holds its output on thin air is worth setting up properly the first time.
Easy-to-run heat for the academic crowd
Rentals near Mars Hill University tend to want a fireplace that lights simply and reliably for tenants — sealed gas fits, and a millivolt or battery-backup unit keeps heat coming when the power drops, which matters at this elevation. Whatever the choice, the altitude setup is part of a permitted, pressure-tested install: we pull the permit with Madison County and meet the inspector, thirty minutes north of our Asheville showroom. A landlord's handyman legally can't connect the gas in North Carolina; we can, and we stand behind the whole job. Call (828) 545-0525.
