I have a harman accentra insert and i am currently burning a blend or barefoot and turman pellets depending on what i grab outta the garage recently sticking to the turmans. My issue with the turmans and no other pellets ive burnt like the barefoot, or great american pellets have done this, is in the burn pot the pellet ash hardens and forms a soldid mass of ash overnight when im not awake to clean the ash out that builds up on the lip of the pot what makes this brand do this and no other brand so far has caused an issue like this? Thanks for any help/ suggestions feed setting is on 4 auto light stove temperature setting around 75
