Westinghouse 151888R Inducer Orifice Condensing Furnace

Product Description

The WESTINGHOUSE 151888R is an inducer orifice designed for use in residential condensing gas furnaces. The inducer orifice controls airflow through the inducer assembly, helping to maintain proper combustion air pressure and draft across the heat exchanger. This component is a direct OEM-style replacement part installed by licensed HVAC technicians during routine maintenance or inducer assembly service. At 1.75 inches, the orifice sizing is matched to specific furnace configurations and must not be substituted with an incorrect size, as improper airflow can affect combustion efficiency and pressure switch operation.

This inducer orifice is used on residential condensing furnaces in the 080-12 and 100-16 configurations. These are typically high-efficiency gas furnaces installed in residential applications where the inducer motor and draft assembly work together to manage flue gas exhaust. The part is suited for replacement during inducer servicing, pressure switch troubleshooting, or any repair that involves disassembly of the inducer housing and flue outlet components.

Key Features

• Sized at 1.75 inches for precise airflow control within the inducer assembly
• Designed for residential condensing gas furnace applications
• OEM-style replacement for 080-12 and 100-16 furnace configurations
• Supports proper combustion air pressure and draft performance
• Direct fit reduces installation time during inducer service calls

Compatibility

Designed for use on the 080-12 and 100-16 Residential Condensing Furnace configurations as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the furnace and shut off the gas supply before beginning any work on the inducer assembly or flue components. Verify the orifice size matches the furnace model requirements before installation, as an incorrect size will affect pressure switch calibration and combustion performance. Follow applicable local codes and manufacturer service documentation throughout the repair.
