It ran out of fuel this morning so before filling and turning back on i figured I should clean it once, since the ash pan was getting close to being full. The dealer said it only needs cleaned when the pan gets full. I regularly scrape the burn pot and wipe the glass, so today I turned the stove to test and started brushing and scraping the ash into the pan and brushing the inside of the top (heat exchanger?) got all of that knocked down and then took out the pan and cleaned the fins on the blower wheel and ran the long brush through the exhaust to clean off the sensor, and vacuumed it all out . Also took the plate off the bottom of the burnpot, where the ignitor is located and vacuumed it out also. So did I miss anything? The Combustion blower would not turn off when I was ready to clean it even though it was off before I started and came on when I turn the stove to test mode, I had to unplug the stove to get it to turn off. All in all not such a bad job, I do need to look for a better vacuum, I have a Rigid 16 Gal shop vac, and the hose and attachments are to big to get into the little cracks and crevices.
