Determine whether hood will discharge vertically (3W' x
10" or 7" Round), or horizontally (3W' x 10" only).
Decide where the ductwork will run between the hood
and the outside.
Choose a straight, short duct run to allow the hood to
perform most efficiently. Long duct runs, elbows and
transitions will reduce the performance of the hood. Use
as few of them as possible. Larger ductwork may be
required for best performance with longer duct runs.
