As seen in the video, our Pacific Energy Summit LE stove pipe sits quite loose in the stove collar. Stove pipe is double walled. It was installed by certified installers, however I’m not sure this is how it should be. We’ve had it about a year, and last winter and so far this fall we’ve cleaned every month or so, with significant creosote being removed each time. I think it’s likely pulling room air through that loose fitting. We measured the inner portion of the stove adaptor and it’s approx 5 5/8 inches, and I believe the stove collar is 6in. Looking for suggestions on how to fix this, whether there are different sized adaptors a person could get?
