PLANNING DUCTWORKINSTALLATION
Begin planning ductwork by deciding where the duct will run
between the range hood and the outside. For best performance,
use the shortest possible duct run and a minimum number of
elbows. There are several choices shown - FIGS. 1A - 1E.
In more complex ducting situations, a 3-1/4" rectangular ducting
range hood can be converted to a round duct by means of a
transition.
FIG. 1A. Ducting directly through the wall (for range hoods
mounted on an exterior wall). Shown are two ways to duct through
an outside wall. If a wall cap is used directly off the back of the
hood, special care must be taken to make sure that the damper
in the damper/duct connector on the hood and damper in the
wall cap do not interfere with each other when the hood is oper-
ating. This could result in either inadequate air delivery or back
drafts. If this condition does exist, remove the hood damper flap.
Sometimes when using a wall cap it is easier to duct vertically
and then use an elbow as shown in FIG. 1B.
FIG. 1C. Ducting straight up through the roof using
3-1/4" x 10" rectangular duct. (For single story installations.)
FIG. 1D. Ducting between the ceiling joists (for multi-story instal-
lations) or through the soffit space above the cabinets (where
the soffit connects to an outside wall).
FIG. 1E. Straight up through the roof using 3-1/4” x 10” to 6”
round duct transition and 6" round duct (for single-story installa-
tions).
FIG. 1F. Straight up through the roof using 7" round duct (for
single-story installations). Requires optional damper Model Damp
