I went to look at wood stoves today to start getting an education about which one would be best for me. As I read through the installation guide for a Hearthstone Tribute, I found that the maximum chimney length is 30 feet. I assume I would measure the length starting at the top of the stove and stop 3 feet above the peak of the house which is where my chimney would exit. This would make it 34' in my old farmhouse. Will this be a problem ,especially since I plan on installing a rather small stove?
