I've always cleaned my woodstove chimney from the top and it was very straightforward and easy with just a semi-rigid rod and brush. I just got a new Lopi Nex Gen Flush insert which I need to clean from the bottom and am wondering what equipment I should buy to accomplish this task? The chimney liner is about 14 foot high and enclosed in a masonry chimney. It has a slight, maybe 45 degree, bend pretty near the flue opening and is otherwise pretty straight. Any help you can give this newbie will be GREATLY appreciated. Doug Dillingham Ohio City, Colorado
