10Advance PlanningDUCT FITTINGSThis Hood Must Use an8″ Round Duct. It CanTransition to a3-1/4″ x 12″ Duct.Use this chart to computemaximum permissible lengthsfor duct runs to outdoors.NOTE: Do not exceed maximumpermissible equivalent lengths!Maximum duct length:100 foot for range hoods.Flexible ducting:If flexible metal ducting is used,all the equivalent feet values inthe table should be doubled.The flexible metal duct shouldbe straight and smooth andextended as much as possible.DO NOT use flexible plasticducting.NOTE: Any home ventilationsystem, such as a ventilation hood,may interrupt the proper flow ofcombustion air and exhaustrequired by fireplaces, gasfurnaces, gas water heaters andother naturally vented systems.To minimize the chance ofinterruption of such naturallyvented systems, follow theheating equipment manufacturer’sguidelines and safety standardssuch as those published by NFPAand ASHRAE.TotalEquivalent Quantity EquivalentDuct Piece Dimensions Length* Used LengthRound, 1 ft.straight (per footlength)3-1/4″ x 12″ 1 ft.straight (per footlength)90° elbow17 ft.45° elbow10 ft.3-1⁄4″ x 12″90° elbow 43 ft.3-1/4″ x 12″45° elbow 26 ft.3-1/4″ x 12″90° flat elbow 102 ft.8″ round to3-1/4″ x 12″ transition 2 ft.3-1/4″ x 12″ to 8″round transition 5 ft.8″ roundto 3-1/4″ x 12″transition 90° elbow 6 ft.3-1/4″ x 12″ to 8″round transition 90° elbow 13 ft.Roundwall capwith damper 32 ft.3-1/4″ x 12″ wall capwith damper 75 ft.Roundroof cap 44 ft.Total Duct Run*Actual length of straight duct plus duct fittingequivalent.
