After talking to Sherwood Ind/Canada who directed me to the US Northeast dist. in Randolph MA. I was able to confirm that if you're M55 serial number is higher than 230348, than you have the adjustable auger cover. Mine is higher and being virtually out of pellets I was able to carefully get my iPhone in the hopper, take a couple of pics and confirm that it is adjustable. It is set in the middle position with the ability to go up or down two notches. For what it's worth, I was told that if I plan on burning mostly high BTU pellets ( like the Vermont softwoods ) I should set the cover plate in the lowest position.....This brings me to figure out how to access the auger. I have the M55 insert! I plan on pulling it out this evening, but need to know if I remove the side panel...Right of left side? Or, is there a top panel? Appreciate any help on this! When I refilled the hopper (I had to vacuum out the remaining pellets) I was able to put 56 pounds in! It was filled to the brim plus! Thanks, Bill
