DuraVent DuraLiner Oval to Round Flex Pipe: an oval bottom that joins a round liner above
The DuraVent DuraLiner Oval to Round Flex Pipe is a flexible stainless steel section for the bend above a fireplace. Its lower end is oval to fit an oval stove outlet or pass through a narrow damper opening. The upper end joins round rigid liner pipe. Made from one layer of steel, it can be shaped by hand. DuraLiner is DuraVent’s factory insulated double wall pipe for relining a masonry chimney that vents a wood, pellet, coal, oil, or gas appliance. This flex section is only for the bend at the smoke shelf and damper, the fireplace’s smoke passage and movable flap. The old damper comes out first.
Choose a 6 or 8 inch size, then a length of 36 or 60 inches. Any flex extending above the first clay flue tile needs the DuraLiner Insulation Kit around it. At the appliance, an oval stove connector fits an oval or rectangular top outlet. Need thicker steel in the 6 inch size? See the DuraVent DuraLiner Oval to Round Heavy Duty Flex Pipe. The DuraVent DuraLiner Oval to Round Flex Pipe ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
