Recommended vent length Use 3-1/4" x 10" (8.3 cm x 25.4 cm) rectangular or 6" (15.2 cm) round vent. The total length of the vent system including straight vent, elbow(s), transitions, wall or roof caps must not exceed the equivalent of 140 feet (42.7 m) of 3-1/4" x 10" (8.3 cm x 25.4 cm) rectangular or 6" (15.2 cm) round vent. For best performance, use no more than three 90° elbows. To calculate the length of system you need, add the equivalent feet for each vent piece used in the system. See examples below. NOTE: There must be at least one 2" x 4" (50.8 cm x 101.6 cm) wall stud and minimum 3/8" (9.5 mm) thickness drywall or plaster/lath within cabinet opening. Must be able to support 150 lbs.

Wall and roof caps must have back-draft damper. We recommend: ✔using rigid metal vent. ✔that length of vent and number of elbows should be kept to a minimum to provide efficient performance. ✔that size of vent should be uniform. ✔using duct tape to seal all joints in the vent system. ✔using caulking compound to seal exterior wall or roof opening around cap. ✔two elbows should not be installed together. We do NOT recommend: ✔flexible metal vent. NOTE: If flexible metal vent must be used, calculate each foot of flexible metal vent as two feet of rigid metal vent. Flexible metal elbows count twice as much as standard elbows. 6 ft. (1.8 m) 2 ft.
