What does a natural gas to propane conversion kit actually change?
Marshall is mixed-fuel, so a natural-gas-to-propane kit applies whenever an appliance is fed propane it wasn't jetted for. The conversion changes the fuel train only — smaller burner and pilot orifices, a propane regulator or valve spring for the higher pressure, and a readjusted air shutter. Your firebox, venting, and rated heat output all stay exactly as they are.
Steep lots, tight access
Marshall's homes cling to steep hillsides with limited access, and the revitalized downtown is a row of narrow, multi-story buildings built right against the mountainside. That geography complicates chimney routing and draft — but a fuel conversion itself is compact work on the appliance, not the structure. It's often the practical fix when a full re-vent on a tight lot would be a far bigger job than the situation calls for.
Damp gorge air, correct combustion
The French Broad gorge brings cool, damp evenings to Marshall, and a fireplace running on the wrong fuel struggles most in exactly that weather — sooting and burning lazy instead of clean. Propane carries more energy than natural gas and needs more combustion air, so the air-shutter reset in a conversion isn't optional. Skip it and even the right orifices give you a dirty flame.
Permitted with Madison County
We pull the permit with Madison County where the work requires it and meet the inspector, then finish every conversion on the gauges — manifold pressure confirmed, each opened joint leak-tested. Marshall is about 25 minutes north of our Asheville showroom. Bring us the model number and your fuel type and we'll confirm the right kit. Call (828) 545-0525.
