Take a dollar bill and shut the door on it the bill should pull out but take quite a bit of force. If it slides out easily the door isn't sealed properly and you will burn through wood in a hurryLayer of ash makes sense. I'll just have some patience there.
Door seal looks ok but not perfect. I have thought about calling Pleasant Hearth to see if they could send me a new one with some glue because it sticks to the body/housing every time I open it during/after a burn. But it looks like it seals fine otherwise. Does it truly need to "seal" really well?
As for "how full is full", I'll go ahead and run it again either tonight or tomorrow night and take a pic when I load it up. I'd say it's 2x-3x that pic
