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.
3. Total equivalent length of ducting should not exceed
the maximum recommendation of 100 feet for optimal
venting performance.
