Hi there. I have a whitfield quest that I have only had installed for a week. The only pellets I have tried so far are the Canwick hardwood pellets from Canadian tire. I find that I get a lot of ash from these pellets which I have seen other people say the same thing, but they do produce a good amount of heat. today I left home for about three hours and when I came home the flame was really lazy and pellets were sitting on a bed of coals. I shut down the stove and cleaned out the pot, which seemed to be plugged with ash. The stove was set just below medium on both feed and air dials. does anyone have any suggestions on how to prevent this or what settings work well on this stove or possibly which pellets work best in it
