The Goodman 2820005S is a genuine OEM flue collector box built as a direct-fit replacement for GMN080-4 gas furnaces. The collector box gathers combustion byproducts from the heat exchanger and channels them into the induced-draft blower and vent system, forming a critical part of the furnace's sealed exhaust path.

Specifications

Component: Flue / combustion collector box
Material: Corrosion-resistant coated steel
Function: Combustion-gas collection and venting
Includes: Factory gasket seating surface
OEM Part Number: 2820005S
Fits: Goodman GMN080-4

OEM vs. Generic

The OEM 2820005S is stamped to Goodman's exact dimensions so the gasket seats perfectly against the heat exchanger and inducer, maintaining a leak-free seal that is essential for safe flue-gas containment. Aftermarket or fabricated collector boxes rarely match the port geometry precisely, risking exhaust leaks, condensation issues, and pressure-switch faults. Because this part handles combustion gases, an exact OEM fit is important for safety.

Installation Difficulty

Advanced. Replacing the collector box requires removing the inducer assembly, replacing gaskets, and verifying a proper seal and draft. This is a job for a licensed HVAC technician; plan on 60–120 minutes. Always shut off gas and power first.
