We had a wood insert installed this spring and the chimney swept, but not the fire place. Even though the liner was insulated, we kinda smell it from time to time. Hoping paint and peel would help. Sure it works, only if I was patient enough to slowly peel from one corner to another side. Long story short, I mistaken painted back left corner of the fire place with the insert and liner in place, big mistake! Now I have a hard time reaching in to peel it. The liner and stove connection were cemented. My question is how hot would you think the backend of the stove would get during normal operation, e.g. 400 degrees or so?
