I, actually my BF & I just put in new gaskets on our doors. The cement container says after an hour or dry to the touch I can fire her up. I am interested in all of your opinions, wait longer? Another question, I bought a thermometer, I have never use one on any stove I ever run before. My stove man said placing it in the middle of the stove will tell me the temp of the flue, your thoughts? I trust the guy but value all your thoughts on this. Come spring when I replace the pipe, I plan on having one on/in the flue. Thanks!
