Hello, I have been living in this 150 yr old home for 18 months. It has a hearthstone HearthStone soap stone stove which was installed within the last 15 yrs. I was attempting to do a cleaning of the chimney when I noticed the bottom of the chimney clean-out is un-sealed. I have attached some pictures to help visualize what I ran into. The stove vents into the chimney above the clean-out, I just scooped a small pale full of debris from the bottom of the clean-out. I was able to get my phone into the clean out and take a picture and noticed it is open through the top. This means when I burn, embers may be falling down into the clean-out, which is unprotected. I feel is a big concern, but am looking for advise before I go any further.
Thank you.
Thank you.
