Hello, newb to this forum. For the past two years I have heated with a garrison 2 with no issues at all besides the firebox being to small and not burning overnight for cold mornings. I recently picked up a garrison 1, much larger. I installed this stove yesterday to my existing flue using a adapter, well now anytime I open the door to add wood or even start a fire it smokes like crazy? No issues similar with the smaller stove and I've tried just about everything I can think of. The flue is clean. I've searched around on bing and other forums to no avail of what I already tried.any help much appreciated!
