What's the mechanical difference between a natural gas and a propane fireplace?
Hendersonville runs on natural gas along the mains — Main Street, Laurel Park, and the growing Spartanburg Highway subdivisions — so the quiet sealed gas units our retirement customers favor are jetted for utility line pressure. A propane version is the same appliance with smaller orifices and an LP regulator. The fuel at the curb decides which calibration you get.
Why the low-maintenance crowd lands on natural gas
A lot of Hendersonville buyers want a fireplace they never have to think about, and being on the mains delivers exactly that: flame at the flip of a switch, no tank gauge to read, and nothing to top off before winter. Mechanically the natural-gas burner runs a larger orifice than its propane twin because gas carries less energy per cubic foot and shows up at gentler pressure — so the fuel train is tuned wider and softer, not the metal reshaped.
That's the same reason a natural-gas unit and its propane sibling put out identical rated BTUs once each is jetted correctly. Same heat, different plumbing.
The chimney problem is separate from the fuel problem
Henderson County's clay-heavy soil settles foundations and stresses older masonry chimneys, which matters for venting — but it has nothing to do with orifice size or regulator setting. It's worth untangling the two: a cracked flue is a venting fix, while wrong-fuel soot is a calibration fix. A sealed direct-vent unit sidesteps the aging masonry entirely and still gets jetted for whichever fuel your street carries.
We pull the permit with the Henderson County office and meet the inspector on every gas line we run, so the fuel side is documented and pressure-tested no matter what the chimney is doing.
