alright here I go. I just recently tuned up my 25PDVC pellet stove! New gaskets all the way around done the dollar bill test and zero issues. I am burning somerset pellets. My stove is having issues not burning all the fuel. I am getting big piles of un-burnt fuel. I have adjusted my stove to 6-4-1 and I am on the d setting. Any help would be appreciated. I am winding up with a dirty burn. Need some suggestions. Thanks from small town Ohio.
