Field Controls 46073000 Draft Inducer

The Field Controls 46073000 (Model DI-1) is a professional-grade 115Vac 1550 RPM Draft Inducer engineered for high-performance venting in gas and oil-fired furnaces, water heaters, and boilers. This unit is specifically designed to fit 3" to 6" pipe, providing the necessary negative pressure to overcome drafting issues caused by short chimneys, undersized vent pipes, or negative building pressures. As a veteran-preferred solution for combustion efficiency, the DI-1 ensures that exhaust gases are cleared from the heat exchanger before ignition and maintains a steady oxygen supply throughout the heating cycle. Operating at 0.43 Amps with thermal protection, this inducer is rated for systems up to 120,000 BTU. For compliance with NFPA codes and to ensure a safe, interlocked startup sequence, this motor must be installed by a licensed contractor using a compatible CK series control kit. Its compact 8-3/32" x 8-13/16" footprint allows for reliable installation in confined mechanical spaces.

• Enhanced Draft Performance: Successfully mitigates venting failures in long horizontal vent runs and atmospheric systems where natural draft is insufficient.
• Universal Application: Compatible with both oil and gas-fired equipment, including high-efficiency boilers and residential water heaters.
• Verified Reliability: Features a high-torque 1550 RPM motor with internal thermal protection to prevent overheating during continuous cycles.
• Optimized Combustion: Improves overall system safety by ensuring a 100% negative pressure environment within the flue pipe.

Which pipe sizes are compatible with the DI-1?
The Model DI-1 is engineered for seamless integration with standard flue pipes ranging from 3 inches to 6 inches in diameter.

Does this unit require a separate control kit?
Yes, for proper operation and safety interlocking, a Field Controls CK-series control kit is required to manage the pre-purge and post-purge cycles.

Can this inducer be used with oil-fired appliances?
Absolutely. The 46073000 is rated for both oil and gas applications, provided the total input does not exceed the 120,000 BTU threshold.
