It was a good day to put hte liner in, The first thinkg i learned is chimneys are not start down. So if you go to put one in tapper the edn of it so it will not get cought up. Had to ob long so it could o through the damper about 4in wide. A friend of mine made me an 8 in wood collar with two long rods through them so we could make the end round again. Over all is was some what hard but if I did it again it would be a pice of cake.
