Flex duct used for exhasut flue.

[jlybolt]

Never seen flex duct used as a flue. Strait runs of ductwork were type b.
Flex duct ? rated?

Looks like flexible B-vent to me. . .

The label on the flex will indicate it's type, but this looks okay to me.

Never seen flex before used at this application. The flex had no label. Does anybody have links to manufacturer site or technical info?
Thanks Jeffrey for the reply.

It's labeled at its connector, near the furnace. . .

I ran into this the other day and got on here to check on it. I'd not seen this used before. Good information. Thanks everyone.
