PLAN YOUR DUCTWORK
Toensurethattheblowerperformstoitshighest
possiblecapacity,ductworkshouldbeasshort
and straight as possilbe.
Theductrunshouldnotexceed35equivalent
feetifductedusingtherequiredminimumof6"
roundduct.For10"roundductingwiththe1200
cfminternalmotoror900/1200remoteblower,
use55equivalentfeet.Calculatethelengthof
theductworkbyaddingtheequivalentfeetin
FIGURE 5 for each piece of duct in the system
AnexampleisgiveninFIGURE 6.
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.
