Why does my gas fireplace burn differently after being converted between natural gas and propane?
Around Mars Hill, rural Spring Creek and Gabriels Creek homes lean on propane and wood while the university area fills with easy-use gas rentals — so the fuel varies house to house. A conversion done wrong here usually means a natural-gas fireplace over-fueled on a propane tank: sooty, roaring, black logs. Propane needs a smaller orifice and a regulator dialed to its higher pressure.
Propane valleys, gas-ready rentals
Out in the Spring Creek and Gabriels Creek valleys, propane and wood carry the heating load, while landlords near Mars Hill University favor gas fireplaces that a tenant can run at the flip of a switch. When a unit gets relocated onto propane without re-jetting, it over-fires: propane holds far more energy per cubic foot and arrives at higher pressure, so a natural-gas burner runs it tall, lazy, and sooty. This is one of the colder spots we serve, so those fireplaces run hard all season — the manufacturer's LP kit resets the orifice, pilot, and regulator so they run clean instead.
