    Questions
    What size do I need?

    The appliance's own instructions set the chimney diameter; match it, and keep the whole chimney one diameter.

    What clearance does it need?

    At least 2" to combustibles, per DuraVent's listing. Never fill the clearance space with insulation.

    Can I mix DuraTech with other brands?

    No. DuraVent's instructions require authorized DuraTech parts only, to keep the chimney listed.

    Where are the installation rules?

    In the documents above: supports, firestops, enclosures and chimney height are set by DuraVent's instructions, and the installer follows them.

    Why is there no photo?
