The 4053501S chimney collar is a genuine Goodman/Amana OEM venting component engineered as a direct-fit replacement for the AMS80453AXAA 80% AFUE gas furnace and compatible Amana/Goodman multi-position models. The collar creates the sealed transition between the furnace flue outlet and the vent pipe, ensuring combustion byproducts are safely routed to the chimney or vent system. A properly seated collar is essential for maintaining draft, preventing flue gas leakage, and keeping your furnace operating within its certified specifications.
This is a genuine OEM Goodman collar built to the exact tolerances of your furnace's flue outlet. Generic universal collars often require field modification and may not seal cleanly, risking flue gas leaks. The OEM part drops in without cutting or adapting.
Easy (1/5) — Basic hand tools. As with any flue component, ensure the furnace is powered off and inspect for a proper airtight seal after installation. If you are unsure about venting safety, consult a licensed HVAC technician.
