Cleaning Russian Fireplace
I have a Russian/Finish/Masonry fireplace. It was in the house when I bought it. They are supposed to stay clean but when I looked in the cleanout there is an inch of fluffy soot all around the interior. I suspect this is insulating the brick from the heat as it does not work well. It only has one cleanout in the back of the top horizontal run (run goes to right and left from the cleanout).
How do I clean out the other runs and everything else?
Also the damper seems to be partially blocked as I can only turn the knob from about the 11 oclock to 1 oclock positions. Any ideas on how to fix it?
Bonus question: Any ideas about adding an oven?
