Description
The S1‑1NP0347 is a natural‑gas → propane (LP) conversion kit for furnaces. In other words, if you have a furnace that was originally designed to run on natural gas, this kit lets a qualified HVAC technician convert it to run safely on propane (LP) instead. This can be useful if your home or facility switches fuel type, or if natural gas isn’t available but propane is. The conversion kit includes the necessary burner orifices and components to properly adjust gas flow and combustion parameters so the furnace operates correctly and safely under propane.
Key Features
- Type: Gas conversion kit (Natural Gas → Propane/LP)
- Intended Use: Converts induced‑combustion furnaces originally set up for natural gas so they can safely operate on propane (LP) gas.
