Hi all, new to the forum and had a question. I just got my new Pitboss 700 and did my first burn. I followed the directions per the manual, using pitboss brand fruit blend of pellets. My question was I noticed that when I was done, the entire inside was covered in black soot. I wiped it all down afterwards. I didn’t know if that was normal for a first burn, considering it burns off everything from the factory or if maybe something was wrong? Thanks for any help towards this noobie!
