DuraVent DuraChimney II 8 to 16 inch Chase Top Flashing: a lid that lets the chimney enclosure breathe
The DuraVent DuraChimney II 8 to 16 inch Chase Top Flashing is a metal lid for the framed box around a chimney, called a chase. It covers the top without sealing off the airflow. A 1 1/2 inch air gap surrounds the pipe, and the included spacer clips raise the flashing 1/2 inch above the chase. Those openings let air move through the enclosure. DuraChimney II is DuraVent’s air cooled chimney, a double wall pipe in 8 to 16 inch sizes for fireplaces that burn wood, oil, coal, or gas.
Choose an 8, 10, 12, 14, or 16 inch diameter on this page to match your chimney. Inside the chase, keep 2 inches of empty space between the chimney and framing, insulation, drywall, or anything else that can burn. Leave that space unfilled. Need a top made to fit your chase? Use the DuraVent DuraChimney II 8 to 16 inch Chase Top Collar for a custom top when this flashing does not fit. The DuraVent DuraChimney II 8 to 16 inch Chase Top Flashing ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
