DuraVent DuraChimney II 8 to 16 inch Chase Top Collar: for a chase top made to fit
The DuraVent DuraChimney II 8 to 16 inch Chase Top Collar is a collar for a custom chimney enclosure lid. Use it when the standard chase top flashing, the ready made lid, will not fit. A sheet metal shop or installer makes the lid to size, then secures and seals this collar in its center. The air gap and edge vents must remain open. 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.
The chimney usually sits inside a framed enclosure called a chase, with 2 inches of air around it. Its raised lid leaves room around the pipe for ventilation, with the storm collar and cap above it. The chimney sold here has a galvanized steel outer wall. Stainless steel requires a quote from DuraVent customer service. Choose an 8, 10, 12, 14, or 16 inch collar to match your chimney. If a standard lid fits, you do not need this collar. Need that lid? See the DuraVent DuraChimney II 8 to 16 inch Chase Top Flashing ready made lid. The DuraVent DuraChimney II 8 to 16 inch Chase Top Collar ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
