I am new, so please excuse what may seem like an obvious question. I wanted to check the feeder body of my stove. I removed the right rear panel (as you are looking at the stove from the front) and removed the wing nut. From the diagram in the manual, it looked like it should be a rather uncrowded box where I could easily vacuum any fines. I couldn't even see the bottom of the feeder body, there's a metal bar there. I had to reach my finger over and feel around. I didn't want to move anything. Am I supposed to flip this up? Am I even at the right place?? It certainly wouldn't be easy to vacuum.
