Interior Blower Installation
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 transitions. Check location
of floor joists, wall studs, electrical wiring or plumbing for
possible interference.

3. The system will operate most efficiently when the ductwork
does not exceed 40 feet of equivalent duct. The chart, above,
shows equivalent feet of elbows and transitions. The number
of feet of straight duct plus the equivalent feet of transitions
and/or elbows to be used should equal 40 feet or less.
NOTE: The equivalent feet of various roof and wall caps has
been taken into consideration. Do not include them in this
calculation.
