The FERGUSON ENTERPRISES b4022700 is a 3-inch in-shot burner designed as a direct OEM replacement component for gas furnace systems. In-shot burners ignite the gas-air mixture inside the heat exchanger, producing the combustion flame that drives the heating cycle. This part arrives brand new in original factory packaging, making it a straightforward drop-in repair component. Licensed HVAC technicians typically install this part during burner failure diagnostics or routine heat exchanger service on residential gas furnaces.
The b4022700 is suited for gas furnace applications where the original in-shot burner has degraded, cracked, or failed to sustain flame. In-shot burner replacement is a common service task encountered during heating season calls, particularly on aging furnace installations where burner ports become corroded or clogged. This part is supplied as a genuine OEM component, ensuring dimensional and material consistency with the original factory-installed burner assembly.
Designed as an OEM-style replacement in-shot burner for residential gas furnace systems requiring a 3-inch burner. Verify dimensional fit and burner count against the original equipment before installation.
Installation should be performed by a licensed HVAC technician. Shut off gas supply and disconnect electrical power to the furnace before removing the burner assembly. Follow local codes referencing the International Fuel Gas Code (IFGC) for gas appliance service procedures. Inspect the heat exchanger and manifold for damage or debris before installing the replacement burner.
