The Goodman 4053501S chimney (flue) collar is a factory-original venting component for the AMH81405DNAA gas furnace. It secures and seals the transition between the furnace's flue outlet and the vent pipe, ensuring combustion gases are safely and efficiently routed out of the equipment. A cracked, corroded, or missing collar can cause vent leaks and improper draft, so replacing it with the correct OEM part is important for safe operation.
The genuine 4053501S is stamped and formed to match the furnace flue outlet exactly, giving a clean, leak-free seal with no field fabrication. Generic sheet-metal collars often need trimming and extra sealant to fit and rarely match the original gasketing, increasing the risk of flue-gas leakage. For a safety-critical venting part, OEM is the correct choice.
Moderate. The collar mounts with standard fasteners at the flue outlet. Basic hand tools and correct vent sealing are required; always verify a proper draft after any venting work, and use a licensed technician when in doubt.
