1.  The interior down-

draft blower system is

designed for use with

3-1/4" x 10" ductwork

(can be transitioned

to 6" round). Three

different discharge

directions are avail-

able with side-to-

side adjustment for

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 transi-

tions. Check location of floor joists, wall studs, electrical

wiring or plumbing for possible interference.
