Improve Heating Efficiency
In-Line Draft Inducers assure positive draft
when restricted boilers and furnaces, poor
chimneys or negative pressures in build-
ings prevent proper exhaust of combus-
tion gases. The Venturi action starts air
moving up the stack instantly and keeps it
moving smoothly. In-Line inducers are
built for long-lasting, trouble-free service
and available in sizes and capacities to
meet virtually all heating system require-
ments. The Vari-Draft control permits
adjustment to individual job require-
ments.
Vents/Chimneys utilizing In-Line
Draft Inducers must be vertically terminat-
ed above the roof line.
