Any time a chimney vent passes through a ceiling a firestop must be installed to protect the combustible materials against ignition from the heat of the vent. This attic firestop/vent sleeve assembly is designed to be installed with the 4" x 7" direct vents used by Napoleon direct vent stoves and fireplaces. This part replaces the parts W585-0072 and W170-0063. Using Napoleon venting parts that are designed to work with your Napoleon appliance helps to ensure that the vent installation is safe and effective.
