I would like to install a potbelly wood burning stove in my house. I plan on doing it in the back corner of my house in my kitchen. The kitchen has lenolium flooring on top of concrete slab. My plan was to get a professional to install the chimney and tackle building the hearth on my own. For the floor I was simply planning to pull up the flooring and just lay brick directly on the concrete slab. The stove will be in a corner so I was planning on also bricking the walls on each side up to whatever height is needed. The one question I have right now is, can I lay the brick right up against the sheet rock wall or does there need to be a layer of insulation there, perhaps just a space for airflow? Do I need to rip out the sheet rock and put something else? Nothing perhaps? I don't have any of the supplies yet including the stove. I'm hoping that my grandmother can find the potbelly they used to use. Any advice or problems with my current plan that anyone has is welcome. Thanks!
