Goodman 4810007S Flue Collector Box

The genuine Goodman 4810007S flue collector box is a heavy-duty combustion component for the GMNT120-5B gas furnace and compatible Goodman/Amana models. It gathers flue gases from the heat exchanger tubes and channels them to the induced-draft blower for safe venting. Because it seals the exhaust path and mates directly to the heat exchanger and inducer, dimensional accuracy is essential — this factory OEM box is stamped and gasketed to the exact original spec.

Specifications

Function: Flue gas collection / combustion exhaust routing
Material: Corrosion-resistant coated/stainless steel
Interfaces: Heat exchanger outlets and induced-draft blower
Includes: Collector box (verify gasket/hardware needs for your unit)
Fits: Goodman GMNT120-5B and compatible furnaces
OEM Part #: 4810007S

OEM vs. Generic

A flue collector box handles hot, corrosive combustion gases, so material grade and a leak-free seal are non-negotiable. The OEM 4810007S guarantees the correct fit and flange geometry; generic or salvaged boxes risk exhaust leaks and carbon-monoxide hazards. Always choose OEM for combustion parts.

Installation Difficulty

Advanced (4/5). Requires disconnecting the induced-draft blower and gas train, removing the old collector box, replacing gaskets, and leak-testing the flue path. This is combustion work — a licensed HVAC technician is strongly recommended, and a combustion/CO check should follow the install.
