Hi to all. This is my first post. I've been trying to read as much as I can the last few days. Brain is starting to overload.
I see from what I read that you definitely need to install a liner when installing a fireplace insert. I have a Masonry fireplace with a Copper cap which I would like to keep. I've included some pics so you can tell me if it should work. Can I install the liner and keep my Copper cap on top. I may still be able to put the liner cap on top inside the copper cap. Sounds like I would then need to put a metal seal around the liner to keep air from moving around the liner. Any and all suggestions taken, please chime in. Does this sound like it will work? Also I measured from the top of the lip inside the copper cap to the top lip inside my fireplace at 20'. Would a 20' section of SS liner be enough, or do I need more. I plan on doing this myself, so your help is much appreciated. Do you use an insert adapter to connect the insert to the liner or do you connect the liner directly to the insert?
Also I live in South MS. Our winters aren't nearly as bad as most of you. Coldest temps usually around 20. Do I need to insulate the liner or would it be okay without if I seal off both ends on the fireplace flue. I look forward to hearing from a lot of you. hint.
Thanks a bunch in advance.
