The Big Chief is an electric smoker, isn't it? I'm not sure that it is possible to get sweet blue smoke from an electric. The heat is provided by the electric heating element and the smoke if from sawdust, chips or chunks that smolder, but don't burn cleanly. Sweet blue is from a wood fire that is burning cleanly. More than likely when you smoke is gone it is because the wood is gone.
