IN-LINE DRAFT INDUCER
AUTO-DRAFT® Inducers assure positive draft when restricted boilers and furnaces, poor chimneys or slight negative pressures in buildings prevent proper exhaust of combustion gas. The venturi action of Tjernlund Auto-Draft Inducers starts air moving smoothly. These units are quick and easy to install and completely automatic in operation. Tjernlund’s unique design and durable construction makes them trouble-free and reduces maintenance to a minimum. The Vari-Draft Control permits adjustments to the individual job requirement.
The motor shaft must be level and horizontal to avoid excessive wear on bearing.
If change in vent pipe size is required, use a tapered increaser or reducer.
In-Line Inducers should be installed on a section of single wall vent pipe in order to assure proper performance.
Do not use In-Line Draft Inducers on condensing heating equipment.
We recommend the use of a carbon monoxide detector in all mechanical rooms.
