I spent a few years doing heating and refrigeration installations in the first part of the Seventies, so I am out of the loop. Most wood stove installations on a structure would requre the use of "Triple-wall" vent piping, when you have a combustable wall material. I have seen a large amount of installations in my area with a single wall pipe, but the vent is going through a steel siding of some sort. The triple wall is used to get the size of the outlet hole down to a reasonable size. a single wall can be used, but the required distance around the pipe is larger. This would require the metal flashing to be a lot larger in size. Any heating/cooling installer in the area, or the county or city engineer's office will be able to give you the code requirements for the install. If you are in a city, then the city most undoubtedly will want to inspect, so that they can get their fair share of the money that is in your pocket. I know that if you have a wood stove and you stoke that thing up with the right wood, you can melt a cheap quality flue pipe and then you really have a problem, so spend the good dollars here if you can. The County Highway Department shop that I used to work at, had a shop[ built wood stove and we had it glowing a few times. I have seen the heavy wooden work bench smoking at 3 feet away from the stove. We got it that hot. The metal shop siding was turning brown, as well.

The insurance agencies get nervous, due to the possibility of gas fumes moving across the floor and igniting in an open vented stove. If your stove is one that can be installed outside and ducted into the building, then it is pretty safe, since the combustion air is from outside the garage. There are many shopowners in my area, that have not asked their insurance agents, you know how most of us Country boys know what is right, far more than any old insurance agent does. If the shop or house burns down, then the agent wins, by not paying off on the fire damage.
