Want to get some fresh thoughts on this.
I was about to pull the trigger on a great deal on a Catalytic insert with an 8" exhaust so I called up Rockford, my go to people for chimney supplies to see about getting the parts to convert from 8" to 6" on my 25ft insulated 6" liner and had a good conversation with Eric one of the support people there, he sounded very knowledgeable on the subject and we talked for some time about it.
Basically what he mentioned is don't do it. He has had customers try it and report bad back puffing and smoke spillage when opening the door, and as well the stove not able to damper down as much as it should. I brought up the issue of user error and he said he has seen it to many times with many different installs to be user error (ie open bypass for a minute before opening the door). He was very frank about it and said he could sell the parts to do it but if I had not bought the stove already to look at other ones with a 6" exhaust.
This was news to me seeing as since my liner has great draft especially with being 25ft and insulated, but he mentioned the exhaust size is tied in with the door opening size and if the two do not match you will have issues.
So if anyone has done this and has a success story I am all ears, I know I have told others to try it in the past, I hope that was not bad advice.
