Field Controls 46090700 DI-3 Draft Inducer Assembly for 8-12 Inch Pipe

The Field Controls 46090700 DI-3 Draft Inducer Assembly is a powerful solution designed to resolve drafting problems in residential and commercial heating systems. This inducer unit effectively addresses issues caused by short chimneys, undersized vent pipes, long horizontal vent runs, and negative building pressures that can compromise proper venting.

Key Features:

• Compatible with oil or gas-fired furnaces, water heaters, and boilers
• Fits vent pipes ranging from 8 to 12 inches in diameter
• 115 volt AC, 60 Hz electrical operation
• High-performance 1725 RPM motor for reliable draft induction
• Compact dimensions: 12-9/16 inches length x 10-1/8 inches width x 9 inches depth
• Maximum flue gas temperature rating of 750°F at installation location

How It Works:

The DI-3 draft inducer creates negative pressure in the burner chamber by forcing airflow through the chimney or vent system. When the thermostat calls for heat, the draft inducer energizes and establishes proper draft before the burner ignites, ensuring safe and efficient combustion. The unit continues to run throughout the heating cycle, providing a constant supply of oxygen to the burners and expelling combustion gases safely outdoors.

Installation Notes:

This draft inducer is designed for vertical venting applications only and is not intended for sidewall venting. A control kit (sold separately) is recommended when venting single or multiple appliances. Professional installation by a qualified, licensed contractor is required to ensure proper operation and compliance with NFPA 54, NFPA 31, and applicable local codes. The unit must be properly grounded according to the National Electrical Code.
