Description
The Tjernlund Products D-3C In-Line Draft Inducer is engineered to establish and maintain a reliable, consistent draft in venting systems for gas- and oil-fired heating appliances. Designed for in-line installation within the flue or vent connector, this inducer draws combustion gases away from the appliance and out through the vent, helping to overcome draft problems caused by poor chimney conditions, long vent runs, or negative building pressure.
Tjernlund is a recognized leader in combustion air and venting solutions, and the D-3C continues that tradition with a robust, field-proven design suited for residential and light-commercial applications. By mechanically inducing draft, the unit helps improve combustion efficiency, reduce appliance cycling, and extend equipment life.
