I just bought a Cemi Concept II and this forum has been very helpful in reading on how the stove works. My problem is that most people wont install it due to the age even though it has a second stage burning. I also just had my chimney repaired with new tiles and i dont want to have to pay to line it as well as there is not a way to attach it to the liner. Can i install this without a chimney liner? How dangerous is this? Also do i have to do anything but slide it into place and then put insulation on the trim? I appreciate all the help. 1 other thing does anyone know where i can get the mica at a reasonable price since the glass is not recommended?
