The Goodman 22309501 Flue Pipe is a genuine OEM combustion venting component for AMH950453BXAC gas furnaces. It channels exhaust gases from the heat exchanger to the vent system, and its correct diameter, length, and material are essential for safe draft and complete flue-gas removal. Because this part carries products of combustion, using the exact factory component is a safety-critical requirement — not an area to substitute.
Generic flue sections may not match the furnace's flue collar diameter or sealing surfaces, risking exhaust leaks and carbon monoxide hazards. The genuine OEM 22309501 is dimensioned to the factory vent path for a proper, sealed connection and preserves warranty and code compliance.
Moderate (2/5). Turn off gas and power, remove the vent connections, and install the replacement flue pipe with correct clearances and sealed joints. Because this handles combustion gases, we strongly recommend installation by a qualified HVAC technician and a post-service combustion/CO check.
