Natural to Propane Gas Conversion Kit for Bryant 80, 90 and 95 Percent Furnaces with Multi-Size LP Orifices for 340AAV, 310AAV, 313AAV and 315AAV Models

The Natural to Propane Gas Conversion Kit for Bryant 80, 90 and 95 Percent Furnaces with Multi Size LP Orifices for 340AAV, 310AAV, 313AAV and 315AAV Models (KGANP4601ALL) provides the complete OEM approved parts package required to convert multiple Bryant furnace families from natural gas to propane. This kit typically includes the LP regulator spring for the furnace gas valve, a full set of LP main burner orifices correctly sized for each compatible input range across the 340AAV, 310AAV, 313AAV and 315AAV series, an LP pilot orifice if required by the model, and the conversion labels needed to document the fuel change. Designed to maintain safe combustion and proper manifold pressure, the kit supports furnace sizes that use various orifice diameters including common LP drill sizes such as No. 54, No. 55 and 1.25 mm depending on furnace BTU rating. During installation technicians remove the natural gas orifices, install the LP orifice set that matches the furnace input, replace the regulator spring in the gas valve, and adjust the manifold pressure to the LP setting specified by Bryant which is typically around 10.0 inches WC. After reassembly technicians verify ignition, inspect flame quality, record temperature rise, check for leaks and apply the conversion label inside the cabinet. Engineered for multi model compatibility, the KGANP4601ALL kit gives technicians a consolidated, factory correct solution that simplifies LP conversions across several Bryant furnace families while maintaining OEM performance and safety.
