Around Brevard you're usually on propane, not a gas main, and that changes the sizing math. LP runs at a different pressure than natural gas and needs its own orifices, and the tank often sits well off from a downtown home or a Connestee Falls cabin, so the buried run can be long. The appliance connects near 1/2-inch, but demand and distance decide the rest.
Sizing a propane line, not a gas-main branch
On propane, the pipe from your tank's second-stage regulator to the fireplace still gets sized the same way any gas line does — by the appliance's BTU demand and the total developed length of the run — but the starting conditions differ. LP reaches the house at low pressure through the regulator, and a 30,000-BTU cabin unit like a Kozy Heat Springfield asks a real amount of that supply. When the tank sits across the yard from the house, as it often does out here, that buried, outdoor-rated run adds length fast, and length is exactly what nudges a line from 1/2-inch up to 3/4-inch.
Wet ground and long buried runs
Brevard's 80-plus inches of rain a year matter here too. A propane line crossing a soggy Transylvania County yard has to be outdoor-rated and set correctly, and a fireplace tucked into a moisture-prone chimney chase adds vertical run on top of the horizontal. We account for all of it — every foot, every fitting, every appliance already on the tank — so the fireplace burns clean and full instead of lazy and yellow. Get the size wrong and you'll see it in the flame.
This is licensed work
Extending gas or propane line in North Carolina is licensed work. A mason can build you a gorgeous firebox and a landscaper can trench the yard, but neither can legally connect the propane — we can, and we pull the permit with Transylvania County and meet the inspector. Never DIY gas pipe. Call (828) 545-0525 for a free in-home assessment.
