*Equivalent lengths of duct pieces are based on actual tests and reflect requirements for good venting performance with any downdraft cooktop.

†Measure and list feet of straight duct used. Count and list the quantity of all other duct pieces for the “Number Used” of each type.

IMPORTANT

For maximum efficiency, use the shortest and straightest duct run possible, with as few fittings as possible. For satisfactory performance, the duct run

should not exceed 100 feet equivalent length.

Venting performance is improved by using larger diameter duct.
