Yes, it is very important to preseason your grill before cooking. Pre-seasoning helps to burn off any chemicals and oils left over from the manufacturing process.
Steps to pre-season your grill:
1. Fill the hopper with charcoal approximately ¼ - ½ full.
2. Start your grill following the START-UP instructions and set the temperature to 250°F (121°C) for 60 minutes.
3. Next, set the temperature to 400°F (204°C) for 30 minutes.
4. After 30 minutes, shut down the grill following the SHUTDOWN instructions.
5. Allow grill to cool COMPLETELY.
6. After the grill has cooled, use a napkin or cloth to rub a light coat of cooking oil on smoke and sear grates, warming/smoking racks, charcoal grate and the inside of the grill lid and body.
7. Then, repeat steps 3-6 at a temperature of 350°F.
*Frequent seasoning helps to prevent rusting. If rusting occurs clean with a steel brush, apply vegetable shortening and heat as indicated above.
