What size gas insert will fit my existing fireplace?
Around Mars Hill many rural homes up Spring Creek and Gabriels Creek run on propane or wood, so fuel is the first thing we settle — a propane insert needs the correct orifice and pressure. Then the insert fits when its body clears your firebox's four interior measurements with the required clearances.
Propane, wood, and what that means for fit
The valleys around Mars Hill lean on propane and wood heat, so we start by confirming what you burn. If you're converting a wood-burning firebox to gas, that's one of our common jobs, and the insert has to seat in the existing masonry opening — front width, rear width, height, and depth all measured cold. A propane unit is spec'd for LP so it doesn't soot, and the whole thing is licensed gas work permitted through Madison County.
Easy, switch-on heat near campus
University-area rentals and homes here do well with a sealed gas insert precisely because it asks so little — flame at the flip of a switch, no hauling wood, no cold-start smoke — which suits tenants and busy households. A Valor or Regency insert set for the local fuel seats cleanly in most of these openings, and Valor's millivolt design keeps heat coming when the power's out. The surround frames whatever gap remains around the original opening so the finish looks intentional.
One of the colder spots we serve
Mars Hill runs cold, so an insert sized for real output earns its place, and the firebox has to be deep enough to seat it. We're 30 minutes north of the Emma Road showroom — call (828) 545-0525 for a free in-home measure, and we'll bring the tape and confirm your fuel in one visit.
