Welcome new to smoke.
I'm no expert on it, but basically seasoning a smoker gets rid of the "junk odors" inside - all the new stuff stinks. So you want to first follow the manufacturers instructions from the book.. then burn it.. books don't know everything. Usually you will "burn in" the smoker. After burning in I like to smoke something like regular store bought, sliced bacon that will maybe splatter a bit to give the smoker that good used look and hold in the "good smoke" smells.. after this it only gets better.
That's my humble opinion.. others will post too. If you don't know something then ask these people are great.
Again welcome
