Hello, took out my 4 inch old gas stove vent in my chimney and everything looks good, no cracks in the mortar at all. Bought a new chimney cap at Lowe's and all ready to go. I opted to open the clean out on the bottom of the chimney and it just fell out. I am assuming that is a problem. It is a piece of metal, pretty thick and I am going to clean it up and paint it before I put it back, but I have two questions:
1. What should I paint it with? Can I just use a rust-o-leum product or should I go with something for a high temperature since it is part of the chimney, or since it is just a trap?
2. How or What should I use to put it back in place? I am assuming some sort of furance cement. Any suggestions on how to place it until it "sets." Since it isn't screwed in at all.
Thanks again everyone!
