Can you put Rutland RTV inside the pipe? I have a bad smoke leak problem at the stove adapter, and last year I put so much silicone on the stove adapter to the stove I cant seem to get if off now. When I pulled the rest of the pipe and looked inside the adapter with a flashlight I notice some of the silicone made it to the edge where the adapter and the stove meets, but it is not sealed good enough. I can see where smoke can escape. My question is can I just seal up where the red arrows are pointing at? I know there is back RTV showing but I had no idea it went that for or if this is ok to do. Thanks for the help!
