I need some help. I have and Enviro empress free standing stove. I have burn 3 1/2 ton Lignetics pellets no problem. Love them. I am out so I have tried New England Pellets, horrible burn pot filled up. Now I was excited to try Barefoot pellets. I messed with the stove all day to get the settings just right thought I had a good burn going , went to bed the pot is overflowing. My stove just went through a deep cleaning last week, and i vacume every day. What am i doing wrong. Is my stove only going to burn Lignetics? I never have any ash or problems with Lignetics. Please help. Is it because the empress is a small stove. Thanks Veronica
