DuraVent FasNSeal Flex Top Cover Plate: covers the chimney top and supports the rain cap

The DuraVent FasNSeal Flex Top Cover Plate is a flat plate that covers the chimney opening around a Flex liner. It supports the Flex rain cap, which is sold separately. The plate slides over the liner and rests on the chimney top, with sealant that stays soft between the chimney and the plate. FasNSeal Flex is DuraVent’s flexible stainless steel liner that carries a high efficiency gas appliance’s exhaust up through an existing masonry chimney. Choose a 2, 3, 4, 5, 6, 7, 8, 10, or 12 inch size on this page.

Flex is for relining a crooked masonry chimney when a side wall vent is not possible. It bends around changes in direction, while its smooth inner wall helps exhaust flow and liquid condensate drain. It works only with FasNSeal parts. At the chimney bottom, DuraVent strongly recommends a condensate drain directly after the male flex adapter, the connector where the vent exits the chimney. The liner’s connection to that adapter is supported at the base. Need the separate cap? See the DuraVent FasNSeal Flex Rain Cap. The DuraVent FasNSeal Flex Top Cover Plate ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
