Just studying up on my stove so that I am familiar with it inside and out. While eyeing the parts explosion diagram, It looks like the sides each bolt to the back and front plates respectively with one bolt, and the back and front plates each bolt to the bottom plate with 2 bolts and the lid sits down on top and fastens with the two 3mm screws. Is there any welding together of these pieces done at the factory or are the inside seams just sealed with some sort of cement? I haven't taken the top off mine and don't reckon I will until after this first burning season just to visually inspect that everything is still in safe working order. I don't want to be dependent on the labor of others with anything concerning this stove so I want to know i have the know-how to tear it down and build it back up in the event I have to replace something.
