The exterior of the bulding is made out of brick, and the interior is made of concrete. Because of the materials the building is made of I think the risk of the buiding burning down is relatively low. The ground is made of pavement and the surrounding area is a large private parking lot, so I'm not super worried about stray embers. Is there a way to mitigate the smoke charring against the side of the building? My primary concern is related to draft and whether or not this type of setup can work without sending a stove pipe all the way up the building. Thank you for your input!
