The Goodman B4022700 3" In-Shot Burner is a genuine OEM combustion burner for the ADSS801005CXAB gas furnace. In-shot burners fire fuel directly into the heat-exchanger tubes; a clean, correctly seated burner is critical for proper ignition, a stable flame, and safe, efficient heating. Replace burners that are rusted, clogged, or producing an uneven or yellow flame.
The genuine OEM Goodman burner is manufactured to the exact venturi geometry and mounting slot of the ADSS manifold, ensuring the designed air-fuel mixture and flame pattern. Generic burners can alter the flame shape, cause flashback, or fail to align to the heat-exchanger inlet. Because burners are combustion-critical, we strongly recommend the OEM part.
Moderate (3/5). Requires shutting off gas and power, removing the manifold or burner-retaining bracket, and correctly reseating the burner to the heat-exchanger port. Combustion adjustments should be verified by a licensed HVAC technician after installation.
