Each in-shot burner directs a precisely shaped gas\/air flame into a single tube of the furnace's stainless-steel heat exchanger. Clean, correctly aimed burners are essential for efficient combustion, quiet ignition, and safe operation — a corroded, rust-flaked, or misaligned burner can cause delayed ignition, sooting, and heat-exchanger stress.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: In-shot burner\u003c\/li\u003e\n\u003cli\u003eBurner size: 3 inch\u003c\/li\u003e\n\u003cli\u003eOEM part number: B4022700\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana (interchangeable)\u003c\/li\u003e\n\u003cli\u003eFuel: Natural gas (verify orifice for LP conversions)\u003c\/li\u003e\n\u003cli\u003ePrimary fit: AMH80403ANAA and related AMH8 furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM in-shot burners are stamped and slotted to Goodman's exact flame-geometry spec, so the flame lands correctly in the heat-exchanger tube and lights off the adjacent burner cleanly. Generic burners frequently vary in slot pattern and throat diameter, which can cause rollout, uneven flame carry-over, and premature failure. When replacing burners, install a matched set for consistent combustion.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires removing the burner assembly, transferring or replacing burners individually, and verifying flame alignment on restart.
