- Want to start off by saying there is a lot of good info on site. Come on from time to time to get info and its always helpful. So, figured I would join and try to get some info on this project. I have a craft insert I would like to make into a working stove for my shop. Little info on shop stick built 20x30 12ft ceilings, drywall inside, and vinyl on outside. Reason for giving info on shop just want to give visual and for questions I have. How far from walls should stove sit? Should I run exhaust out of ceiling or out of wall? If out of wall what kind of protection should I have for vinyl. Size and what kind of stove pipe assuming double walled. Sorry, for all the questions but I want to make sure this is done right. Will get a picture of stove tomorrow, and be happy to answer any questions you have for me. Thanks in advance.
