Permanent label required to identify length of dryer exhaust. Â« on: February 23, 2010, 11:27:33 AM Â». I heard the 2009 Mechanical and Residential codes now require the length of the concealed exhaust duct for the dryer be identified on a permanent label.
Dryer vent pipes properly called vent ducts, come in a variety of materials. Most dryer duct is round and 4 inches in diameter. Some are flexible and others are rigid. Since all types are sold for use with dryers, you would naturally assume that all are suitable for this application. Unfortunately, that is not the case. Vinyl duct, and in some situations, all flexible duct, is not allowed by building codes.
