Welcome from SC. It's good to have you on this great site. There are a lot of really nice folks here who are always eager to share their ideas, recipes and tips. All you have to do is ask and keep reading.
Did you wash out your smoker first? There are some oils and manufacturing residue that needs to wash down. Simple Green, car washing soap or dishwashing soap are good. Just use a brush or cloth and wash it with soapy water. Then spray with water. After that let it dry and coat everything inside, including the grates, with oil. Pam or other cooking oil is good. Spray a liberal coating and build a fire. Run the smoker at 250-300* for several hours and then let it die down. You're ready to cook. Some folks say to throw on a chicken or something to cook while its seasoning, but I just let it go. There's a lot of oil burning, etc. so I just don't bother with cooking anything.
Occasional cleaning will help to keep your cooking fresh and will keep everything running smoothly.
Good luck and good smokin', Joe. :grilling_smilie:
