So I've had my Castille Quadrafire for 3 years now. Very nice stove, but I've had increasing difficulty keeping it clean. At first I thought it was an issue with junk pellets, but I finally figured I had to call in the pros for a professional cleaning because I've been getting a very lazy fire really quickly after I clean the burn pot, and have had to clean it about every 12 hours or so. I called around, and couldn't find any local service technicians, so I broke down and decided to clean it myself. After fiddling around for a while I figured out how to undo the top plate, and also how to take out the firebrick. An hour later, my stove is clean, back together and running like a champ. By the way, it was loaded with soot and ash... thank goodness I got to it! If I can clean mine...you can clean yours...get to it!
