In-shot burners deliver the fuel-air mixture into the heat exchanger tubes for clean, quiet, and efficient combustion. Over time burners can rust, warp, or clog with debris, causing rough ignition, delayed lighting, or a rollout condition — replacing them restores safe, even flame across every tube.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B4022700\u003c\/li\u003e\n\u003cli\u003eType: In-shot (monoport) gas burner\u003c\/li\u003e\n\u003cli\u003eLength: 3 inches\u003c\/li\u003e\n\u003cli\u003eMaterial: Corrosion-resistant coated steel\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMTH045-3 gas furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine Goodman burners are matched to the furnace's manifold pressure and orifice sizing, ensuring the flame carries over correctly from tube to tube. Generic burners may have slightly different venturi geometry, leading to noisy ignition or uneven heating. For proper flame characteristics, OEM is strongly recommended.
