I was cleaning around my stove and had an urge to see of the vent pipe attached directly out of the back of my stove (a whitfield profile 30 FS-2) was nice and snug, and to my surprise I am able to easily twist it clockwise and counter-clockwise. I had the dealer who sold me the stove professionally install it, and the specs call for a bead of hi-temp silicone be applied to the stoves quick connect before the vent pipe (duravent) is attached. Wouldn't this have made a tight, locked seal that would require some force before one was able to twist the pipe? Did the bozo forget to put on the bead of silicone? Or should there be some play after the sealer dries? I have not had any smoke issues, and I have a new smoke and carbon monoxide detector in close proximity, but now I am now a bit concerned.
