Williams 8909 Conversion Kit

The Williams 8909 is a field-proven Natural Gas to Propane (LP) conversion kit specifically engineered for Monterey Plus Top Vent Furnaces. Designed for compatibility with the 50098 and 50096A series, this kit ensures a precise fuel conversion while maintaining the unit's 50,000 BTU rating. As a veteran-grade OEM furnace part, the assembly includes the necessary main burner orifices and a dedicated pressure regulator for Williams brand gas valves. Contractors should verify that the furnace was manufactured after 2013, as older models may require alternative configurations depending on the serial number. Utilizing a gas furnace field conversion kit like the 8909 ensures that the manifold pressure is correctly adjusted for the higher energy density of liquid propane, preventing soot accumulation and ensuring optimal combustion efficiency in residential and light commercial settings.
