Flexi Flue Liner for Open Fire

    Hi all,

    I am looking to install a flexi flue liner in an old stone cottage chinmey. It looks pretty narrow in places.

    I know open fires required at least 8" flue liners but I don't think that will fit. Even a 6" flue might be tight by the looks of it.

    Is it possible to use a 6" liner and squeeze it to a more oval shape to try get it to fit? Would that suffice?

    Or if a 6" liner could fit down, would installing a glass door on the open fire be an option when it comes to regulations?

    The fireplace is in the bedroom and I don't think I will be using it very often. There is damp/high humidity in the room and after I had open up the fireplace the humidity and the room felt drier and warmer. So I was thinking of keeping the fireplace open to pull out the damp air. The stone chimney, I'm sure has some holes in it so I was planning on installing the liner and filling around it with sand lime mix.

    Anyone ever use flexi liner on old stone chimney and had trouble getting the right size?
