In-shot burners deliver a precisely shaped gas jet into each heat-exchanger tube for clean, even ignition and efficient combustion. Over time burners can corrode, clog with rust, or distort the flame — replacing them with the correct factory burner restores smooth light-off and a proper blue flame across the manifold.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: In-shot burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eFunction: Directs gas\/air mixture into the heat exchanger tube\u003c\/li\u003e\n\u003cli\u003eBrand fit: Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003ePrimary model: AMH80704BXCB\u003c\/li\u003e\n\u003cli\u003eOEM Part #: B4022700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B4022700 is sized and ported to match the AMH80704BXCB manifold and orifice spacing, so each burner lights in sequence and burns at the designed rate. Generic burners with a different port pattern can cause rough ignition, delayed light-off, or an uneven flame that leads to rollout and lockouts. For safe, consistent combustion, replace burners as a matched set with genuine parts.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDifficulty: Moderate.\u003c\/strong\u003e Expect 30–45 minutes. Shut off gas and power, remove the burner assembly or slide the burners off the manifold, and note orientation so the crossover ports align. Seat the new burner over the orifice at the correct depth. Because this is a combustion component, we recommend a qualified technician verify flame quality and check for proper ignition and rollout after replacement.\u003c\/p\u003e\u003cp\u003eOrdering a full set?
