The B4022700 is the genuine OEM 3-inch in-shot burner for the Goodman ACVC80805CXBD 80% AFUE gas furnace. Each in-shot burner directs a precise jet of gas-air mixture into its heat-exchanger tube, where the igniter or carryover lights it for clean, even combustion. Rust, scale, or a distorted burner port causes rough ignition, flame rollout, delayed light, and sooting — replacing worn burners restores reliable, efficient heat.
OEM in-shot burners are matched to the furnace's manifold pressure and orifice sizing for the correct flame pattern and BTU input. Generic burners can misfire or alter the air-fuel ratio, risking incomplete combustion. For combustion safety, use the genuine part and replace burners as a set.
Moderate (3/5). Shut off gas and power, remove the manifold, slide out the old burner, and install the replacement aligned to its orifice. Plan 30–60 minutes; verify flame quality after. If unsure, hire a licensed technician.
