We had an M55 installed back in December. It ran great all winter for us. We've had it off for a couple weeks because we ran out of pellets. I tried to fire it back up yesterday and it appears that the hopper is clogged. My dumb question is I have no idea how to get at the hopper since it's an insert. I've tried sticking my hand in with the unit off but my arm isn't long enough and I'm thinking this CANNOT be how it's done LOL! I'm assuming the stove pulls out from the wall but the owner's manual is useless and our installer is closed until tomorrow. I've searched high and low all over the internet and can't find anything. HELP
