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