I have the issue of the ash builing up in the burn pot and will not fall over into the ash tray like it did for the first year we had our stove. I scrape and clean my burn pot daily, I also remove and clean the igniter area weekly, exactly the same as I did for the first year, and it ran great. I can't for the life of me figure out why this is happending. It just mounds up and chokes the flames, still get heat but I know it's not as efficient as it was.
