What size gas insert will fit my existing fireplace?
For Hendersonville, an insert fits when it clears your firebox's four interior measurements with clearances — but here we also check that clay-soil settling hasn't racked the opening or cracked the flue first, because a shifted masonry chimney changes the numbers. Once the opening measures sound, we match an insert built to seat in it.
Measure the movement, not just the opening
Henderson County's clay-heavy soil settles foundations and stresses older masonry chimneys, so a firebox that was square when it was built may have shifted. We take front width, rear width, height, and depth, but we also look for a racked opening, stepped cracks, and a clay flue liner that has pulled apart. If the masonry has moved, we sort that before sizing, because an insert seats to the opening as it is today.
Quiet, sealed heat suits the area
Hendersonville's downtown and its Spartanburg Highway subdivisions include a lot of retirees who want a fireplace that lights at a switch and asks for nothing else. A sealed gas insert on the natural-gas mains does exactly that, and a Napoleon Oakville X4 or a Kozy Heat Chaska runs clean and low-maintenance once it's in. Extending the gas line is licensed work we permit through Henderson County and pressure-test.
One trip from the showroom
We're 25 minutes north of Hendersonville at our 629 Emma Road showroom, so a free in-home measure is an easy visit and you can stand in front of the display models before you commit to one. A surround panel frames the difference between the insert's face and your existing opening, so even an older, oversized firebox finishes clean. Bring your four numbers in, or let us take them at the house — call (828) 545-0525.
