I have been burning for the last couple nights after install. I think my fire is to tall out of the burn pot,on high it has about a 10 inche flame and med its the 6" . The flame does not look lazy at all not much black smoke at all. The burn pot is clean and holes and fans are clean, I cleaned everything before installing. How does the feed rod work. does it move up and down or side to side. It seems to be pushed all the way down. the book is a bit unclear on this Or is there a adjustment on the control box like I read in a previous post.
