I have been burning some lg granules pellets this is the second bag and after about 8 hrs the burn pot is so full it has to be cleaned it will almost put the flame out are these just cheep pellets or is there something wrong with the stove?before these I burned one bag of premier and this didn't happen,I have a bag of fireside ultra to try next and also a couple bags of greene team hardwood but I don't want to try these out if it is a stove thing I run it at 4-4 till it warms up than at 1-3 after that. The stove is a 55-shp 10 that I got last week the bottom 3 settings are the factory settings they are 6-4-1
