Toensurethattheblowerperformstoitshighest
possiblecapacity,ductworkshouldbeasshort
and straight as possilbe.
For satisfactory performance the duct run
shouldnotexceed50 equivalent feet if ducted
usingtherequiredminimum6"roundduct.For
10"roundducting with the 1200 cfminternal
motoror 900/1200 remoteblower,theduct
runshouldnotexceed75 equivalent feet.

For best results, use no more than three 90°
elbows. Make sure that there is a minimum of
24" of straight duct between elbows if more
than one is used. Do not install two elbows
together. If you must elbow right away, do it
as far away from the hood's exhaust opening
as possible.
