DuraVent DuraTech All-Fuel Aluminum 0/12 to 6/12 Pitch Roof Flashing - For 12" Inner Diameter DuraTech: A venting pipe with an inner diameter of 12" is required for this unit. For installation, a Storm Collar must be ordered separately. Roof leaks are never fun to deal with, and if you've just constructed a chimney, you may have opened the door to that potential. With the DuraTech All-Fuel Aluminum Roof Flashing you have the ability to make sure that chimney pipes with a 12" inner diameter are installed so securely with the roof that the chances of a leak of any type occurring are so remote that you have no need to even think about the possibility.
