Field Controls 46075300 DI-2 Draft Inducer

The Field Controls 46075300 DI-2 Draft Inducer is a 120V HVAC control designed for 5" to 8" pipe installations. It solves drafting problems caused by short chimneys, undersized flue pipes, and negative building pressures. The unit is suitable for oil or gas-fired furnaces, water heaters, and boilers. It is not for systems requiring millivolt or 24V control kits without separate accessories.

Capacity and headroom

The inducer operates at 1550 RPM drawing 78 watts and 1.1 amps at 60 Hertz. Thermally protected operation provides a safety margin during extended run cycles. It handles long horizontal vent runs and outside exposed chimneys where natural draft is insufficient. The unit runs out of capacity when venting multiple appliances without a dedicated control kit.

Replaces Tjernlund D3 and D-3

This draft inducer directly replaces the Tjernlund D3 and D-3 models. The jump is worth it when existing equipment fails to maintain proper draft due to installation constraints. It upgrades performance for single-appliance venting in challenging flue configurations. Buyers needing integrated 24V or millivolt controls must purchase a separate DI Pak.

Questions about this item

Will the 120 V DI-2 draft inducer work with my existing 24 V gas-fired furnace control system?

The DI-2 runs on 120 V, 60 Hz power. For 24 V or millivolt appliances a DI Pak control kit is required, which includes the necessary relays and wiring to integrate safely.

How can I confirm the inducer is running correctly once installed?

Verify the motor spins at 1550 RPM, draws about 1.1 A at 78 W, and that the thermal protection has not tripped; steady draft at the vent outlet indicates proper operation.

What comes with the 46075300 DI-2 and what must I purchase separately?

The unit includes the draft inducer motor and housing for 5"–8" pipe. A control kit or DI Pak for 24 V / millivolt systems, vent pipe, and wiring are sold separately.
