Hello, Was wondering if anyone could be of assistance in helping me out in this Traeger. I am picking up a free traeger. Appears to be older as it has the round offset box vs the square box like the newer ones. Any help with owners manuals, parts listing etc would be appreciated. I have a 6 month old smaller traeger but hoping I can fix this up and be well under what a new one would cost me. Looks rough but hoping its salvageable. Lady says it will run about 20 minutes then shut off .
