    Is there a special connector to join or more sections together? If not, how do I connect the pieces to reach farther?
    1 Answers
    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.

    Will this work on other brands of fireplaces that use the same 4x7 setup?
    1 Answers
    This flex venting is specifically tested and listed for use with Napoleon fireplaces only. It will likely fit other brands that require a 4 x 7 flex liner, but the listing for the product would be voided. This could cause issue during the inspection process or in the event of an insurance inspection.

    How can I connect a direct vent gas stove to a masonry fireplace out of the stove up and horizontally into the chimney?
    1 Answers
    The most effective way to do this is to use a masonry chimney adapter kit. The kit that we carry is the Dura-Vent DirectVent Pro Masonry Chimney to Direct Vent Conversion Kit - 46DVA-KMC. This assembly is designed to allow you to run standard Simpson Duravent pipe to the horizontal connection on the chimney. You would then use the first adapter and thimble to switch to a flexible 4" aluminum liner inside the chimney. The liner will vent exhaust gases, while the air around the liner can be drawn back down into the stove. The second adapter and top plate supports the other end of the liner. A cap can then be added to seal the installation. This installation can only be done if the stove is listed for this type of retrofit and can use Simpson Duravent piping. Many stove manufacturers offer and adapter that will size their flue collar to the slightly different Simpson Duravent pipe.

    Are the ends of this vent attached to the fireplace and termination shield using clamp bands? If so, is this flex vent compatible with non-Napoleon fireplaces? In the photo it does not look like any proprietary connections are used.
    1 Answers
    This flexible vent is attached to select Napoleon direct vent fireplaces and termination caps with screws and high-temperature sealant. Please note that this flexible vent has not been tested or listed for use with non-Napoleon appliances.

    Are there any spacers in this to keep the pipes from touching on another when the are installed or is that offered somewhere else?
    1 Answers
    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.
