5. Setup and Installation
Follow these steps to install your new grill grates:
- Preparation: Ensure the grill is off, cool, and disconnected from its fuel source. Open the grill lid.
- Remove Old Grates: Carefully lift out the old grill grates from the cooking chamber. Dispose of them properly.
- Clean Grill Interior: This is an opportune time to clean the interior of your grill, including burner covers and the bottom of the firebox, removing any debris or grease buildup.
- Place New Grates: Position the new BBQration DPP11 cast iron grates into the cooking chamber. Ensure they sit securely on the grill's support ledges.
- Initial Seasoning (Recommended): Before first use, it is highly recommended to season the cast iron grates. Apply a thin, even coat of high smoke point cooking oil (e.g., flaxseed, grapeseed, or vegetable oil) to all surfaces of the grates. Place them in the grill, close the lid, and heat the grill to a medium temperature (around 350-400°F or 175-200°C) for 1-2 hours. Allow the grates to cool completely before use. This process creates a non-stick surface and protects against rust.

6. Operating Instructions
Using your cast iron grill grates effectively enhances your grilling experience.
- Preheating: Always preheat your cast iron grates thoroughly. Heat the grill to your desired cooking temperature for at least 10-15 minutes. Cast iron retains heat exceptionally well, providing even cooking and excellent sear marks.
- Cooking: Once preheated, the grates are ready for cooking. For best results, apply a light coat of cooking oil to the food or the grates just before placing food on them.
- Temperature Control: Cast iron maintains consistent temperatures. Adjust your grill's burners as needed, but be aware that cast iron will hold heat longer than other materials.

7. Maintenance
Proper care and maintenance are crucial for the longevity and performance of your cast iron grill grates.
7.1 Cleaning
- After Each Use: While the grates are still warm (but not scorching hot), use a stiff-bristled grill brush to scrape off any food residue.
- Deep Cleaning: For stubborn residue, you can wash the grates with warm water and a mild soap. However, avoid harsh detergents or abrasive scrubbers that can strip the seasoning.
- Drying: Immediately after washing, thoroughly dry the grates to prevent rust. You can place them back on the grill over low heat for a few minutes to ensure all moisture evaporates.
7.2 Re-seasoning
If your grates start to show signs of rust or food sticking, they may need re-seasoning.
- Clean the grates thoroughly, removing any rust with a steel wool pad if necessary.
- Dry completely.
- Apply a thin, even coat of high smoke point cooking oil to all surfaces.
- Heat the grates in your grill at 350-400°F (175-200°C) for 1-2 hours.
- Allow to cool. Repeat this process if needed to build up a strong seasoning layer.
7.3 Storage
Store clean, dry, and seasoned cast iron grates in a dry environment to prevent rust. If storing for extended periods, a light coat of cooking oil can provide additional protection.

8. Troubleshooting
Here are solutions to common issues you might encounter with cast iron grill grates:
- Food Sticking: This usually indicates insufficient seasoning or not enough oil on the grates/food before cooking. Ensure grates are well-seasoned and preheated, and apply a light coat of oil.
- Rust Spots: Rust occurs when cast iron is exposed to moisture without proper seasoning. Clean off the rust with steel wool, then re-season the grates as described in Section 7.2. Always dry grates immediately after cleaning.
- Uneven Heating: While cast iron heats evenly, ensure your grill's burners are functioning correctly and that the grates are properly seated.
