Commercial Furnace Propane Conversion Kit
Furnace conversion kits are essential for modifying heating systems to operate efficiently with a different fuel type, such as converting from natural gas to propane, or adjusting performance for high-altitude applications.
A complete furnace conversion kit often includes components such as the economizer controller conversion kit, which optimizes air and fuel mixture for efficient combustion, and the high-altitude conversion kit, which adjusts burner and gas pressures to maintain safe operation at elevated locations. Gas-liquid propane conversion kits provide the necessary orifices, regulators, and pressure controls to safely switch from natural gas to propane. Thermopile conversion kits ensure efficient ignition by generating the required millivolt power for the gas valve and ignition system, while high-altitude pressure switch kits maintain proper system pressure to prevent flame or combustion issues. Natural to LP conversion kits include all essential components for safely adapting furnaces to liquefied propane fuel.
At PartsHnC, we offer a wide range of furnace conversion kits and related parts, including natural gas to LP conversion kits 2–3.5 ton, ignition conversion kits, conversion kit assemblies, fan timer conversion kits, and hot surface ignition conversion kits from top brands like Lennox, Amana-Goodman, and Carrier, all at affordable prices.
FAQs
When should I replace my thermopile conversion kit?
Replace it if the furnace fails to light regularly, because the thermopile supplies the millivolt electricity required for the gas valve and ignition system.
Why do I need a high-altitude pressure switch kit?
This kit maintains proper system pressure at high elevations, avoiding combustion issues and harmful furnace operation.
Can a gas-liquid propane conversion kit be used on any furnace?
No, it is intended for compatible models. Always double-check your furnace's specifications before switching from natural gas to propane.
Can a high-altitude pressure switch kit prevent furnace shutdowns?
Yes, it maintains proper system pressure at higher elevations, which prevents flame failure and keeps your furnace running smoothly.
