Westinghouse 669717 Inducer Orifice Gas Furnace

Product Description

The WESTINGHOUSE 669717 is an inducer orifice designed for use in condensing gas furnaces. The inducer orifice controls airflow through the draft inducer assembly, regulating combustion air movement to maintain proper pressure differentials across the heat exchanger and venting system. This component is a direct OEM-style replacement part installed by licensed HVAC technicians during scheduled maintenance or after a system fault diagnosis has identified restricted or damaged inducer orifice conditions.

This inducer orifice is specified for the 076E-35C condensing gas furnace. Condensing furnaces operate at high efficiency by extracting additional heat from flue gases, making precise inducer orifice sizing critical to system performance and pressure switch operation. Technicians servicing this unit should confirm the unit model designation before ordering to ensure correct orifice sizing.

Key Features

• OEM-specified inducer orifice for the 076E-35C condensing gas furnace
