Ruud 70-104157-83 Induced Draft Blower 2 Stage 120V

Product Description

The RUUD 70-104157-83 is a two-stage induced draft blower assembly with gasket, designed for use in gas furnaces where controlled venting of combustion gases is required. Operating at 120 volts and 60 Hz, this blower draws flue gases through the heat exchanger and out the vent system, maintaining safe and efficient combustion airflow throughout both stages of furnace operation. The included gasket ensures a sealed connection at the flue collar. Licensed HVAC technicians typically handle installation and replacement of this component.

This induced draft blower is designed for residential gas furnace applications where a left-discharge configuration is required. It serves as a direct OEM-style replacement, maintaining proper venting performance in two-stage heating systems. When replacing a failed or noisy draft inducer, verifying the discharge orientation and stage configuration before ordering is essential to confirm correct fitment.

Key Features

• Two-stage operation supports variable-capacity furnace control
• Left discharge orientation for specific furnace cabinet configurations
• Includes gasket for sealed flue collar installation
• 120 volt, 60 Hz operation matches standard residential furnace electrical supply
• OEM replacement part maintains original performance specifications

Compatibility

Designed as an OEM-style replacement induced draft blower for two-stage residential gas furnaces requiring a left-discharge configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the furnace manufacturer service documentation. Shut off electrical power and gas supply to the furnace before removing the existing blower assembly. Confirm discharge orientation and motor voltage match the original unit before installation. Inspect the gasket seating surface for debris or damage and ensure the gasket is properly seated to prevent flue gas leaks.
