Product Description

The WILLIAMS COMFORT PRODUCTS M118746 is a high altitude conversion kit designed for use with natural gas floor furnaces that have been converted to liquid propane (LP). This kit provides all required orifices to accommodate proper fuel delivery at elevations above 2,000 feet above sea level. It is specifically engineered for the Williams floor furnace model 5005622 that has undergone LP conversion. Licensed HVAC technicians and gas appliance service professionals install this kit to ensure safe and efficient burner operation at high elevation jobsites where reduced atmospheric pressure affects gas combustion.

This kit applies to residential floor furnace installations where the appliance has been converted from natural gas to propane and is located at an elevation exceeding 2,000 feet above sea level. Three orifice sets are included, covering the following altitude ranges: 2,001 to 4,000 feet, 4,001 to 6,000 feet, and 6,001 to 8,000 feet above sea level. The correct orifice for the installation elevation must be selected and installed to maintain proper combustion and appliance rating.
