    March 12, 2020
    Will this work with DuraVent direct vent through the wall high wind vent cap?

    1 Answer
    No, as the DuraVent cap has a slightly smaller OD. You would use the Napoleon Direct Vent Wall Terminal with that vent pipe.

    from Lumberton, NC asked:
    July 23, 2014
    Is there a special connector to join or more sections together? If not, how do I connect the pieces to reach farther?
    1 Answer
    A coupler kit is needed to connect lengths of the Napoleon flexible venting. The correct product to use for this size of Napoleon venting is the Napoleon 4/7 Direct Vent Pipe Coupler Kit. Self tapping metal screws should be used to secure the couplings at each juncture.

    Are there any spacers in this to keep the pipes from touching on another when the are installed?
    1 Answer
    Indeed, these flex pipes feature spacers located at about 8" intervals. They are basically miniature coil springs that keep the pipes from compressing onto one another.
