1.This downdraft blower system is designed for use with 31⁄4″ x 10″ ductwork (can be transitioned to 6″ round). Three different discharge directions are available with side--to-side adjustment for accurate alignment of ductwork.

2.For best performance: Choose the ducting option which allows the shortest length of ductwork and a minimum number of elbows and transitions. Check location of floor joists, wall joists, wall studs, electrical wiring or plumbing for possible interference.

NOTE: The unit is shipped with the 31⁄4″ x 10″ discharge facing DOWN. See the Changing Blower Direction section, if necessary.

Steps to Determine Flexible Ducting’s Equivalent Length

1.Measure the actual amount of offset (Maximum 3″ recommended). The effect upon airflow is dependent upon the amount of offset.

2.Calculate the equivalent ducting allowances using:

( ___ in. offset) x (14 Ft. per inch)

=___ Ft. equivalent length.

3.Ensure that the total equivalent length of ducting does not exceed the maximum recommendation of 100 feet.
