There are two self-tapping screws inside the pellet hopper on this. They are above the visible section of the auger on the burn chamber side of the hopper. These screw into the chute that delivers pellets from the top of the auger to the burn pot. If you removed all the screws from the hopper, you’d have removed these and the chute would have slipped down into the burn pot. Push it back up and line up the holes, re-insert the screws and you should be good to go.
