The code clarifies the provisions for duct materials and installation to reflect current industry practices. Equivalent lengths for fittings appear in a new table and are based on the radius and type of fitting. When a concealed exhaust system with a length greater than 25 feet is installed in accordance with the dryer manufacturer’s installation instructions, the developed length must be identified with a permanent marker. New provisions require protection of the dryer duct against penetration by drywall fasteners.
