Hood Exhaust Duct

Outside ventilation requires

HOOD EXHAUST DUCT. Read the following carefully

EXHAUST CONNECT/ON: The hood exhaust has been designed to mate with a standard 3-1/4" x 10" rectangl llar duct.

If round duct is required, a rectang_,l_r-to-mund transition adapter must be used. Do not use less than a 6" diameter duct.

REAR EXHAUST: If rear or

horizontal exhaust is to be used, care should be taken to align exhaust with space between studs, or wall should be prepared at the time it is comstructed by leaving enough space between wall studs to accommodate exhaust, NOTE: Referencewall template,

MAXIMUM DUCT LENGTH: For satisfactoryair movemen_ the tot_ duct length of 3-1/4" x

10" mctang_fl_ror 6" diameter round duct should not exceed

140feet of epuivalent duct run.

ELBOWS,TRANSITIONS, WALL AND ROOF CAPS, etc., present additional resistance to air flow and are equivalent to a section of straight duct which is longer than their actual physical size. When calcula_hg the total duct length add the equivalent lengths of all transitions and adaptors plus the lengths of all su-aight duct sections. The diagram below shows the approximate feet of equivalent length of some typical ducts.
