Just bought an englander (summers heat) 25-puf and for some reason it isnt burning the pellets completely and as a result, they build up in the burn pot and will back up into the chute. My brother let it burn that way and now there is some scorching near the pellet chute mouth. I have cleaned everything out and it still does not burn the pellets completely, they look charred but still look like pellets. I think my brother messed with the 3 buttons on the bottom of the controls and as such, that could be the problem. My unit was manufactured 12/07. Also, what is the correct orientation of those metal pieces next to the burn pot, the flat squares with the posts in the center? do they face post up or post down into the ashpan? They got knocked around during shipping and I want to make sure they are oriented correctly. I have them post up currently. Tried calling englander but i guess they are off for the holidays, hoping to catch one of them on here.
