Description
The Nordyne 669717R is a factory OEM inducer ring orifice designed to maintain precise combustion airflow in Nordyne-family furnaces. With a 1.38″ orifice diameter, this ring controls the volume of air drawn through the heat exchanger by the draft inducer assembly, ensuring proper fuel-to-air ratios, stable burner operation, and safe flue gas venting.
Product Overview
The inducer ring orifice is a critical combustion component positioned within the inducer housing or collector box. It meters the airflow generated by the draft inducer blower motor, directly influencing combustion efficiency and pressure switch operation. Replacing a worn, cracked, or incorrect orifice ring restores factory-specified performance and helps prevent nuisance pressure switch faults.
