I have an older model wood burner in our house, I have been using it for about 3-weeks now, it is a front load Aerocrat, heres my only problem, when I open the right hand side door no problems, no smoke, nothing but then when I open the left side door it allows smoke to puff into the room momentarily, no matter how slow or how long I leave the right hand door open still the same results with the left door. Even during a good solid secondary burn If I have both doors open then I close the left door smoke will follow it when I open it again, but not with the right door. Any thoughts, or is it just the way the stove is designed inside to move the draft. Thanks
