Draft Inducer for Heating Equipment

The Tjernlund DJ-3 is an in-line draft inducer designed for boilers, furnaces, water heaters and ovens. It supports coal, natural gas and oil fuel types in non-condensing chimney-vented appliances. The unit operates on 115V AC at 60 Hz and draws 0.43 A. Its weight is 7.3.

Suits Chimney-Vented Systems Only

This inducer serves installers needing to meet venting requirements for gas inputs up to 377,000 BtuH or oil inputs up to 300,000 BtuH. It fits vent pipe diameters between 3 in and 6 in. Buyers with condensing appliances, positive-pressure venting or electric-only heating should look elsewhere.

Simple In-Line Mounting

The HAWA-constructed housing installs directly in the vent run with standard mechanical fasteners. Wiring connects to a 115V supply at 0.43 A. The maximum static pressure rating is 0 in wc, so duct runs must remain essentially unrestricted; excessive bends or long horizontal sections will prevent proper draft.

Questions about this item

What vent pipe diameters does the DJ-3 draft inducer accept?

The unit works with vent pipes from 3 inches up to 6 inches in diameter.

Can the DJ-3 share a 115 V circuit with my existing furnace controls?

It draws 0.43 A at 115 V AC, 60 Hz, so it can share a properly rated circuit with other low-draw components.

How do I confirm the DJ-3 is moving air correctly after installation?

Verify the blower spins smoothly, listen for steady airflow, and check that the appliance lights and runs without venting issues.
