The B4022700 is a genuine OEM 3-inch in-shot burner for Goodman and Amana gas furnaces, including the GMPN060-3. In-shot burners fire fuel horizontally into the heat exchanger tubes; each burner draws gas from its orifice and delivers a stable, clean flame. Replace burners that are rusted, cracked, or producing a lazy or yellow flame to restore efficient, safe heating.
Burner geometry, venturi shape, and mounting must match the furnace for proper flame carryover and combustion. Genuine Goodman in-shot burners are built to the exact profile; generic burners can misalign with the orifice or heat exchanger port and cause rough ignition or poor flame. Replace all burners as a set for even performance.
Moderate (3/5). Requires removing the burner assembly, sliding out the old burner, and seating the new one squarely in line with its orifice. Confirm clean ignition and flame carryover across all burners before returning to service.
Gas-side work should be performed by a qualified technician. Leak-check after installation.
