    Or for flex duct.
    A flexable duct connector, is NOT flex duct. They are 2 different things.

    International Code says 14' for flexable duct connector.
    It has no limitation on flex duct.
    Dont think I understand your interpretation, please elaborate because the inspectors fail a job with more than a 14' run of flex.

    That didn't work the way that you wanted.
    Perhaps you should have read the instructions before calling.

    What is the difference between Air Ducts and Air Connectors?

    UL (Underwriters Laboratories), in their 181 Standard for Factory-Made Air Ducts and Air Connectors, defines two categories of flexible "ducts".

    The UL Listed Air Duct must pass all of the tests in the UL 181 Standard. Air Ducts are labeled with a square or rectangular shaped label showing their respective listing. There is no limitation on the length of runs when using UL Listed Air Ducts.

    The UL Listed Air Connector must pass only a limited number of the UL 181 tests, and is labeled with a round shaped label, which states "for installation in lengths not over 14 feet".
    Perhaps you should have read the instructions before calling.

    Thanks benny.


    hivacer.
    Your inspectors most likely don't know there is a difference between a flex connector, and flex duct.

    International Code limits flex connectors, not flex duct.

    Point out to them that they are two different things, they may change their mind.(do it politely )

    It's more fun to rub their noses in it.

    It's the little things in life that make me smile.
