Carrier KGAPN3901ALL Conversion Kit

The Carrier KGAPN3901ALL is a critical LP to natural gas conversion kit designed for high-efficiency Carrier, Bryant, and Payne furnaces. This genuine OEM conversion kit allows for a seamless transition from liquid propane to natural gas, ensuring your equipment maintains proper manifold pressure and thermal output. This comprehensive kit is compatible with fixed-speed, two-stage, and variable-speed condensing furnaces, including popular models like the 58MCA, 58MXA, 310AAV, and PG9MAA. It includes precision-engineered burner orifices (sizes #42 through #45), a silver regulator spring for White-Rodgers 36E/F/G series valves, and necessary conversion rating plate labels to ensure code compliance after the gas train modification.

For a successful field conversion, verify your furnace input rate—this kit handles units between 40,000 and 138,000 BTUH. As a technician, ensure you are adjusting the gas valve regulator to meet the specific gravity requirements of local natural gas supplies. This kit supersedes older part numbers, including KGAPN3501ALL and KGAPN2201ALL, providing a standardized solution for hot surface ignition systems. Always check the existing gas valve before installation; do not use this kit on units equipped with the EF33CZ201 red knob valve.
