I would like to know what other stove's burn bot looks like when run on higher settings. Mine on 1-3 will burn low in the pot and nice and orange, pellets light right away and no black pellets, but on 4 or 5 the pot fills up level with the stirrer, with a mix of around 50% orange pellets 30% black pellets and 20% brown unburnt. I think it needs more air but I run with the dampener all the way out.
