DuraVent DuraChimney II 8 inch 30 Degree Firestop: a slanted plate for an angled chimney crossing
The DuraVent DuraChimney II 8 inch 30 Degree Firestop is a plate for an angled chimney opening. It fits only an 8 inch chimney crossing a wall or floor at 30 degrees from vertical. It goes in an offset, where the chimney angles to one side, rather than a straight section. 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.
Firestop spacers belong beneath each floor or ceiling the chimney crosses, but not at the roof. An insulation shield is needed where the chimney enters an open attic. A roof radiation shield goes at the top of the chase, the enclosure around the chimney, or at the roof exit, whichever ends the run. Use only DuraChimney II parts together. Do not alter them or combine them with DuraTech, DuraPlus, or another brand. For a straight crossing, use the flat DuraVent DuraChimney II 8 to 16 inch Firestop Spacer. The DuraVent DuraChimney II 8 inch 30 Degree Firestop ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
