Hello all, I’ve had a Woodstove (hearthstone phoenix 8611) now for about 5 years that came with our home. I clean the stove and chimney frequently just to be safe. I have a question about the extent of cleaning the Chimney. For my set up I have a clay flue that goes from the basement where the clean out is through the home and out to the roof. Chimney runs through the center of the home where I have a Woodstove on the first floor(ranch). Do I need to brush all the way down to the clean out which sits 12’ below the wood stove or just from the Woodstove up? Thanks all
