When I first got my stove I had a different exhaust setup. The exhaust pipe went through a cover plate over my fireplace and up inside the chimney. Even with the side exhaust gate closed the burn pot would eventually lose out when the corn burned faster than the auger could feed it. I was burning corn back then (less than $2 per bushel) and I was trying to keep the stove running on #1 setting. I was getting too much draft. My dealer suggested pulling the left cleanout plate out until it cut the draft down so the fuel didn't burn so quickly. That worked.

After I got the slide where I needed to pull it out to I put a strip of masking tape on the slide to mark the position. Then when I moved the slide for cleaning I could use the tape for reference to where to reset the slide. Even if you need to change the slide adjustment for a change in fuel, etc. you have a reference with the tape.
I think if you look back in the old forum you can find lots of discussion and pictures about adjusting the draft. Other than adding pellets and dumping the burn pot every couple of days I've got my stove pretty close to "set it and forget it".
