Plan the Ductwork

1. This downdraft blower system is designed for use with 3-1/4" x 10" ductwork (can be transitioned to 6" round). Two different discharge directions are available with side-to-side adjustment for the 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.

Steps to Determine Flexible Ducting’s Equivalent Length

1. Measure the actual amount of offset (Maximum 3" recom- mended). 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.

1. Ensure that the total equivalent length of ducting does not exceed the maximum recommendation of 150 feet.
