Propane to Natural Gas Conversion Kit for Bryant 80, 90 and 95 Percent Furnaces for Multi Model Applications Except 58MVC and 355CAV

The Propane to Natural Gas Conversion Kit for Bryant 80, 90 and 95 Percent Furnaces for Multi Model Applications Except 58MVC and 355CAV (KGAPN3901ALL) provides technicians with all factory required components to safely convert compatible Bryant furnaces from propane back to natural gas. This OEM kit typically includes a complete set of precisely sized natural gas main burner orifices matched to common furnace input ratings across the covered model families, a natural gas regulator spring for the gas valve, a replacement pilot orifice when required, and the conversion identification and responsibility labels for proper documentation inside the furnace cabinet. During installation technicians remove the LP orifices and install the appropriate natural gas orifices from the kit based on the unit’s BTU rating, replace the LP regulator spring with the natural gas spring included in the kit, and set the manifold outlet pressure to the manufacturer specified natural gas value which is typically around 3.5 inches WC depending on the furnace model. After reassembly technicians verify ignition stability, confirm proper flame shape and color, measure temperature rise, inspect for gas leaks, and apply the conversion labels inside the cabinet to document the completed fuel change. Engineered for broad compatibility across Bryant’s 80, 90 and 95 percent AFUE platforms, the KGAPN3901ALL kit gives technicians a reliable, factory correct conversion solution that maintains proper combustion performance and ensures safe natural gas operation without field fabricated components.
