I have a free standing stove in my house with a masonry chimney on the outside of the house. So the flue coming out of my stovemake a 90 above the stove goes into the wall and another 90 going up the masonry chimney. My question is with a soot eater can i make the 90 with the cleaning rod? There is about 1-1.5 feet into the chimney then up. Will these rods make that corner and still work? any help appreciated!
