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.

Model Selection Table and Electrical Data 1. Inputs shown are believed to be maximum capacities for inducers when mounted on pipe sizes shown for ordinary jobs where a moderate amount of mechanical induced draft is required. 2. Consideration is given to typically higher static pressure requirements for larger installations, for the type of fuel burned and for the type of draft control installed. 3. Some ratings may only be valid for extremely short vent lengths due to excessive pressure loss; i.e.
