One school of thought suggests that applying the pepper before cooking can cause the pepper to burn while you cook it, imparting a bitter flavor. Followers of this school suggest grinding pepper onto the steaks after searing them, or right before serving. The other school simply seasons their steaks with freshly ground black pepper before cooking and doesn't give it a second thought.
For metal and cast iron grill grates, coat lightly with a high temperature oil like Canola or Peanut oil – wipe off any excessive oil, install the grates and fire up the grill.  Heat the grill on high and let it burn for ~30 mins.  This will burn all the solvents and impurities off of the heating elements, grill grates, etc.  Note that porcelain grates won’t need a coat of oil, but will benefit from the burn in process to remove any chemicals/impurities that were applied by the manufacturer. 
Brining or soaking the ears in water before grilling is thought to season and also plump the corn. There are two problems with those theories, though: In order to take on any salt from the brine, ears would have to soak for several days, at which point you’re losing valuable sweetness as the ears age. Secondly, if you’re buying fresh juicy corn, you cannot make it any juicier. While soaking may benefit older or off-season ears, it has no added value for fresh summer corn.
Prepare the corn. Trim the silk from the top of each ear to prevent it from catching fire and burning. Peel away the first layer of husks and remove the stalk end using a serrated knife to expose the bottom of the ear. This will make it easier to slide the ear of the husk, post grilling. (Optional: Peel back a 1-inch section to expose the kernels and char some of the corn.)
Check the ignition system. Turn the gas off, and test your ignition button to see if it creates a spark. If both the pressure regulator on the gas tank and the ignition system are running normally (meaning the pressure regulator is tracking and maintaining correct gas tank pressure, and the ignition system is sparking and lighting correctly), you can finish testing the grill by turning the gas back on and lighting the grill up as you normally would.[7]
