Draft Inducer for Gas and Oil Heating Equipment

The Tjernlund Products IL Draft Inducer is built for boilers, furnaces, water heaters and ovens that burn natural gas or oil. It serves non-condensing chimney-vented appliances and operates on a 115V AC, 60 Hz supply drawing 5.4 A. The unit fits vent pipes between 9 in and 18 in diameter.

Practical Limits of the 115V AC Interface

The inducer handles a maximum gas appliance input of 460,000 BtuH and a maximum oil appliance input of 900,000 BtuH. It develops up to 1/8 in wc of static pressure. Appliances exceeding these BTU ratings or requiring higher static pressure fall outside the operating envelope.

Aluminized Steel Housing and Blower

The housing and blower are constructed from aluminized steel for corrosion resistance in flue-gas environments. This material choice supports durability on residential and light-commercial heating equipment. The 115V connection integrates directly into standard appliance wiring without additional control modules.
