Allied Air 77W08 Natural to Lp Conversion Kit

Product Description

The ALLIED AIR 77W08 is a natural gas to liquid propane (LP) conversion kit designed for the 80G2 series 2-stage, variable-speed gas furnaces. This kit provides the orifices, fittings, and hardware needed to convert a furnace configured for natural gas operation to LP fuel. Conversion is required any time the installed gas supply is propane rather than natural gas, and using the correct OEM-matched kit ensures the furnace operates within manufacturer specifications. Licensed HVAC technicians perform this conversion as part of initial commissioning or when a unit is relocated to a propane-fueled site.

This conversion kit applies specifically to ALLIED AIR 80G2 series 2-stage variable-speed gas furnaces. Compatible models listed by the manufacturer include the A80US2V090C20, A80US2V110C20, and A80US2V135D20. These are residential gas furnaces operating on two stages of heat output with variable-speed blower motors. The kit is intended for use during initial installation or when converting an existing natural gas unit to propane service at the point of installation.

Installation Notes

This conversion must be performed by a licensed HVAC technician in accordance with local gas codes and the furnace manufacturer installation instructions. Shut off the gas supply and disconnect electrical power to the unit before beginning any conversion work. The International Fuel Gas Code (IFGC) requires that LP conversions be documented and that the furnace rating plate be updated to reflect the new fuel type. Do not attempt to fire the furnace on LP without first verifying that all OEM conversion components have been installed and that the gas valve and pressure regulator are set appropriately for propane service.
