•A DuraChimney II cap must be used inside the shroud.

•The shroud must not be in direct contact with any of the DuraChimney II components (other than the chase top flashing).

•All open areas of the shroud must be covered with 1/2 in. (13 mm) stainless or galvanized steel mesh screen to prevent debris from entering the shroud.
