The ALLIED AIR 604888-13 is a factory-engineered natural gas to liquid propane (LP) conversion kit designed for single-stage, 90% modulating gas furnaces. The kit includes all required orifices, regulators, and hardware needed to convert a furnace from natural gas operation to liquid propane. It is assembled to OEM specifications to maintain proper combustion characteristics and accurate gas flow after conversion. This kit is intended for installation by licensed HVAC technicians as part of a field fuel-type conversion. Typical applications include new construction sites, rural installs, or existing homes transitioning to LP supply where natural gas is unavailable.
This conversion kit is suited for use with single-stage, 90% modulating gas furnaces. Based on the input data, it is referenced for use with AC Pro 80G1, 95G1, and 95G1E series furnace platforms. The kit covers the necessary components to bring the gas valve, burner orifices, and pressure regulation into compliance with LP combustion requirements. It is not intended for two-stage or variable-capacity furnace configurations unless specifically verified by the manufacturer.
Designed for use with single-stage, 90% modulating gas furnaces. Referenced for AC Pro 80G1, 95G1, and 95G1E series furnaces manufactured under Allied Air Enterprises, including Armstrong Air and Concord branded units.
This kit must be installed by a licensed HVAC technician. Before beginning the conversion, shut off all gas supply and disconnect electrical power to the furnace in accordance with local codes and the IFGC. After installing LP orifices and adjusting the regulator, verify manifold pressure and burner operation per the furnace installation manual before returning the unit to service. Do not mix natural gas and LP components or attempt installation without the OEM instructions included with the kit.
