Great thread on cleaning your stove. I was looking all over the Internet last year the 1st time I did a full cleaning. For the life of me I couldn't figure out how to get that rear fan out to clean it. When I finally did get it out I couldn't get to to clean it thoroughly. I had my guy who installed it come by this fall to watch him do a thorough cleaning and he clipped the zip ties that held the wires tight. They do a crappy job as company to not go over detailed cleaning instructions. Should be a video for each stove. Not to mention the instructions in the manual for the XXV tell you to loosen 3 wing nuts to remove it and not the 2 wing nuts and long bolt that actually exists.
