    Can I use high temperature silicone to seal around the adapter that goes directly into the wood stove?
    1 Answer
    A high temp sealant likely wouldn't be able to withstand the termperatures of the stove or liner. It's generally recommended that if you have to mortar the liner in place that you use a refractory cement.

    Will the DuraFlex stainless steel chimney liner be able to be directly attached to a stove pipe, or the wall thimble, using a flex connector?
    1 Answer
    The Duraflex product can indeed mate to single wall stovepipe by utilizing an appliance adapter. The DuraFlex SS Connector Adaptor for 6 inch Chimney Liner would be the product to use.

    Can this liner be used on a wood stove?
    1 Answer
    This liner can indeed be used to vent a wood stove into an existing chimney, as long as the stove is positioned directly in front of the receiving fireplace opening.

    Finally fixed!
    I finally fixed my mom's 50 year old tile chimney with this kit! Just be aware that this material is thin and easy to dent, kink or puncture during install.
    lightweight, flexible, easy to cut. Easy to puncture, dent or kink.

    replacement liner for old chimney
    I purchased this liner to replace an old,rusted out and unsafe galvanized chimney liner. It easily installed with two people and and hooked up in an afternoon.Total time on the roof was less than 1/2 hour for removal of the old liner and installing the pipe and fastening of the bird protector chimney weather cap. My heater mechanic marveled as to both the quality and the price of the whole unit. He feels that from now on he will do any chimney lining jobs he has by himself instead of subcontracting. He has already added your website to his "list".
