A friend has a LOPI 380/440 that billows smoke out the door everytime you open it. Hot-startup-cool down, all the time(except of course when there is no fire or hot ash and coals...) LOL. His stove has a bottom damper rod and an upper Flue (not sure if its called that or not, but if closed redirects the smoke around some baffles and tubes) We cleaned out the firebox of all ash, and the front edge at bottom of door opening. The damper and what i believe to be flue are both moving open and closed just fine. The stove has been installed for several years and just started doing this so i done think it is a draft issue. On the front edge just inside the door is a little "box" of sorts that wiggles just a bit. It sits between two small baffles that i believe are for the damper. Does anyone know what the "box" is and how to remove it for closer inspection? I removed the fire brick on the bootom and couldnt see how it would come out. The only thing i can think of is the plate that the damper rod goes through. It is riveted in place though, so i cant get in there easily. I look forward to any help you guys have! I love this place and i just found it tonight, look to see me here more frequently!
