Westinghouse 151883R Inducer Orifice Condensing Furnace

Product Description

The WESTINGHOUSE 151883R is an inducer orifice designed as a direct replacement component for residential condensing gas furnaces. The inducer orifice meters airflow through the induced-draft assembly, maintaining proper combustion air balance and supporting safe flue gas evacuation. Correct orifice sizing is critical to combustion efficiency and heat exchanger longevity. This part measures 1.375 inches and is installed by licensed HVAC technicians as part of routine furnace service or inducer assembly replacement. It is a precision-fit OEM-style component intended to restore factory airflow performance.

This inducer orifice is specified for use on the 080-VB(B) residential condensing furnace platform. Condensing furnaces in this class operate with a secondary heat exchanger and a draft-inducer motor assembly that relies on correctly sized orifice components to maintain proper venting and combustion. This part is suited for residential service calls involving inducer assembly inspection, combustion inefficiency diagnosis, or pressure switch troubleshooting where the inducer orifice is identified as the failed or worn component.

Key Features

• OEM-style inducer orifice sized at 1.375 inches for precise airflow control
• Designed for use in residential condensing furnace induced-draft assemblies
• Direct replacement fit eliminates modification during installation
• Supports proper combustion air balance and flue gas evacuation

Compatibility

Specified for use on the 080-VB(B) Residential Condensing Furnace.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down furnace power at the disconnect and close the gas supply valve before servicing the inducer assembly. Verify the replacement orifice diameter matches the original before reinstalling to avoid combustion or pressure switch faults. Follow all applicable local mechanical codes and the furnace manufacturer service documentation during reassembly.
