I have three tons of Maine Woods Pellets (Athens). They are supposed to be premium pellets. However, maybe somebody could shed some light on this. I thought that premium pellets were supposed to have the Member of the Pellets Fuel Institute mark on the bag. The Athens Pellets that I have do not have anything on them pertaining to the Pellet Fuel Institute. Anybody else have these pellets? And do they have the PFI mark on them?????
