The Goodman B4022700 3-Inch In-Shot Burner is a genuine OEM burner engineered for the ADSS800804BXAB gas furnace. In-shot burners deliver a precisely shaped flame into each heat-exchanger tube, and a burner with a corroded, warped, or misaligned throat causes rough ignition, flame rollout, and inefficient heating. This factory-spec replacement restores clean, quiet, reliable combustion.
The genuine Goodman in-shot burner is dimensioned to seat correctly at the manifold spuds and align with the heat-exchanger inlets, ensuring the proper air-fuel mix and flame pattern. Generic burners with slightly different throat geometry can misfire, cause noisy ignition, or trip the flame sensor. When it comes to combustion parts, the OEM burner is the safe, reliable choice.
Moderate (3/5). Requires removing the burner box, sliding out the old burner, and aligning the new one to the manifold orifice. Recommended for experienced DIYers or an HVAC technician. Always shut off gas and power, and verify flame quality after installation.
