to start I capped the two bottom holes of my 25-pdv so it burns hotter.. I got up at 4am to go plow snow filled the stove and cleaned the pot and when I came home my wife just cleaned the burn pot.. So that's a good 14 hours.. I always realized that when you clean the ash build up in the burn pot it runs hot for a few min burning all the excess pellets half burnt.. So when I got home the home the stove over heated and stopped feeding pellets... So overheated.. This is what happens when your wife is in control..
