Hello, I am working on installing a Trolla 107a that's in good condition. I need to mount it so one side is facing the room and the other side is about 13" from the wall. Rather than mounting a huge heat shield one inch from the wall, can I bolt a smaller one to the stove? I would leave room for more than an inch of circulating air between the stove and the shield. I could make it large enough so there would still be metal between the stove and anything combustable within 36". I believe that the standard states a wall shield must be a at least one inch from the wall. Is there a maximum distance? Thanks for your thoughts.
