IMPORTANT: Vents/chimneys utilizing in-line draft inducers must be vertically terminated above the roof line. Do NOT use for side wall venting.
Tjernlund in-line draft inducers assure positive draft when restricted boilers and furnaces, poor chimneys or negative pressures in buildings prevent proper exhaust of combustion gases. The venturi action starts air moving up the stack instantly & keeps it moving smoothly. These units are quick and easy to install and completely automatic in operation. In-line draft inducers are built for long-lasting, trouble-free service and available in sizes and capacities to meet virtually all heating system requirements. The Vari-Draft control permits adjustment to individual job requirements.
Solves Venting Problems Caused by:
Undersized chimneys, negative pressures, long horizontal vent connectors, down drafts, cold equipment starts, restrictive heat exchangers/combustion chambers
Boilers/furnaces, water heaters, modular boiler systems, multiple appliances, bakery ovens, factory processes
