The Goodman 22309501 Flue Pipe is the OEM combustion-venting component engineered specifically for the GKS91155DXAB gas furnace and related Goodman 92%+ AFUE models. This pipe routes hot flue gases from the heat exchanger to the vent system, and its exact dimensions and heat rating are critical to safe, code-compliant operation. A cracked, corroded, or mismatched flue pipe can allow combustion byproducts to escape, so replacing it with the correct OEM part is the safest path back to reliable heating.
The genuine OEM Goodman 22309501 is guaranteed to match the factory bend, length, and heat tolerance for a drop-in fit. Our generic-equivalent option offers a budget-friendly alternative built to the same critical dimensions — a smart choice for experienced technicians who can verify fitment. For venting components we recommend OEM whenever possible because tolerances directly affect combustion safety.
Moderate (2/5). Replacement involves shutting off gas and power, removing the old flue section, and confirming a leak-free connection. Basic tools are required, and any furnace venting work should be pressure/draft tested. If you are not comfortable working around combustion gases, use a licensed HVAC technician.
