    Default Flex flu pipe

    Is the attached flu pipe legal? If so, how come I don't see it more often?

    Stephen,
    As long as the AHJ and the furnace manufacturer allow its use and its going into a properly sized and lined chimney it good be OK Simpson makes a product that looks like this called Dura-Flex very fast to install just a slinky, this looks like a slinky within a slinkey similar to B-vent just flexible. I'd be curious to see how it enters the chimney and what else is vented into the chimney. It looks like a draft induced furnace 80% effeciency +/-. Is it a 4 inch slinky on a 4 inch breech?

    I think its just a 4 inch slinky that connects to a B-vent before it exits the roof.
