Begin planning ductwork by deciding where duct will run between
hood and outside. For best performance, use shortest possible
duct run and a minimum number of elbows. There are several
choices.

OF DUCT
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
operating. 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.
Ducting straight up through roof using 3-1/4" x 10" or 7" round
duct. For single story installations.
Ducting between ceiling joists for multi-story installations or
through soffits above cabinets where soffit connects to outside
walls.
