I have been updating and updating (and slowly updating) the stoves at my parents house as funds would allow. Today I decided I am completely done with it. I bought a BK princess ultra off of craigslist while I was in Michigan. So, now I just have one more install to make and the stove "situation" will be DONE. This one will reside upstairs in the place of the stove pictured. I am going to have to put the 6" liner BACK in because the chase is lined with 8" metalbestos triple wall. Only question i have is: whats the proper way to connect the 6" flex liner with the 6" double wall that will run up into the 8"? I will have a telescoping piece so I can go as high into the 8" as I need. I will be insulating the flex liner with ceramic fiber blanket, probably will use 1/2" to make it easy to slide in. Just for info the chimney I am lining is 18ft tall and completely enclosed in an interior chase (with the exception of the top 18" or so)..
