5NOTE: If you need to install ducts, note that the total ductlength of 31⁄4″ x 10″ rectangular or 6″ diameter round ductshould not exceed 140 equivalent feet.Outside ventilation requires a HOOD EXHAUST DUCT.Read the following carefully.NOTE: It is important that venting be installed usingthe most direct route and with as few elbows as possible.This ensures clear venting of exhaust and helps preventblockages. Also, make sure dampers swing freely andnothing is blocking the ducts.Exhaust connection:The hood exhaust has been designed to mate witha standard 31⁄4″ x 10″ rectangular duct.If a round duct is required, a rectangular-to-roundtransition adaptor must be used. Do not use less thana 6″ diameter duct.Maximum duct length:For satisfactory air movement, the total duct length of31⁄4″ x 10″ rectangular or 6″ diameter round duct should notexceed 140 equivalent feet.Elbows, transitions, wall and roof caps, etc.,present additional resistance to airflow and are equivalentto a section of straight duct which is longer than their actualphysical size. When calculating the total duct length, addthe equivalent lengths of all transitions and adaptors plusthe length of all straight duct sections. The chart belowshows you how to calculate total equivalent ductwork lengthusing the approximate feet of equivalent length of sometypical ducts.EQUIVALENT NUMBER EQUIVALENTDUCT PIECES LENGTH x USED = LENGTHRectangular-to-Round 5 Ft. x ( ) = Ft.Transition Adaptor*Wall Cap 40 Ft. x ( ) = Ft.90° Elbow 10 Ft. x ( ) = Ft.45° Elbow 5 Ft. x ( ) = Ft.90° Elbow 25 Ft. x ( ) = Ft.45° Elbow 5 Ft. x ( ) = Ft.Roof Cap 24 Ft. x ( ) = Ft.Straight Duct 6″ Round or 1 Ft. x ( ) = Ft.31⁄4″ x 10″ RectangularTotal Ductwork = Ft.Installation Instructions* IMPORTANT: If a rectangular-to-round transition adaptoris used, the bottom corners of the damper will have to becut to fit, using the tin snips, in order to allow free movementof the damper.Equivalent lengths of duct pieces are based on actual testsand reflect requirements for good venting performance withany vent hood.
