I assume you can open the hopper to pour more pellets in while the stove is running (we've only run it a couple of times since we got it). In that case, we'll need "heat resistant" gloves, right? Any special kind to touch the hopper while it's hot? (I can't use a regular kitchen oven mitt, right?) We also got brushes and long rods that connect to clean out the pipes. Some glass cleaner and the stove came with a scraper. Will order an ash vac soon. Do I need anything else for cleaning/maintaining? Thanks, T.
