Description
The Lennox 83M74 Gas Conversion Kit is used to convert compatible furnace units from natural gas to propane, enabling proper fuel usage and combustion control in HVAC systems. It is intended for G43UF and G51MP models, allowing safe operation with LP gas. It works by adjusting fuel delivery components such as burner orifices and gas valve settings to match propane combustion characteristics. Applied within burner and gas valve sections, it interfaces with ignition and control components to support correct fuel flow and maintain proper heating operation.
