I didn't season mine by the instructions that Bradley provides. Clean the racks, water bowl, rectangular tray, and drip pan. Insert the drip pan, water bowl (1/2 - 3/4 filled with water), and rectangular tray in the smoker (no need to season the racks). Turn the generator on and set the smoker for 225°F, with the vent wide open. Run this for about 30 minutes to an hour. This is to burn off any residual oils that remain on the metal, after the manufacturing process. Next load the feeder tube with 5 bisquettes (3 if you have bisquette savers). Adjust the vent just wide enough to allow the smoke to fully flow out of the vent, and no smoke is backing up into the generator. Apply smoke for one hour. You can apply more smoke, but at this stage it may be a waste of bisquettes.
