5. Installation
Installing your new BBQ-PLUS cooking grates is a straightforward process. Ensure your grill is completely cool and disconnected from its fuel source before beginning.

- Clean Grill Interior: Clean any debris or residue from the grill's interior, especially the areas where the grates will rest.
- Place Emitter Plates (if applicable): If your grill uses emitter plates beneath the grates, ensure they are correctly positioned.
- Position New Grates: Carefully place the new BBQ-PLUS cast iron cooking grates onto the designated supports within your grill. Ensure they sit flat and are properly aligned.
- Verify Fit: Gently push down on each grate to confirm it is securely seated and does not wobble.

6. Operating Your Grates
Once installed, your cast iron cooking grates are ready for use. Cast iron excels at retaining and distributing heat, making it ideal for searing and achieving consistent cooking results.
- Preheating: Always preheat your grill with the grates in place for at least 10-15 minutes to allow the cast iron to reach optimal cooking temperature. This ensures even cooking and proper searing.
- Seasoning (Initial Use): For first-time use, it is recommended to lightly coat the grates with a high smoke point cooking oil (like vegetable or grapeseed oil) and heat them until the oil smokes. Let them cool, then repeat this process 2-3 times. This creates a protective, non-stick layer.
- Cooking: Place food directly on the hot grates. The excellent heat retention of cast iron will help create desirable grill marks and cook food thoroughly.
7. Maintenance and Care
Proper maintenance is key to extending the life of your cast iron cooking grates and ensuring optimal performance.
- Cleaning After Each Use: After each grilling session, while the grates are still warm, use a stiff-bristled grill brush or scraper to remove any food residue. Avoid using soap or harsh detergents, as these can strip the seasoning.
- Seasoning: Periodically re-season your grates, especially if they appear dry or food starts to stick. Apply a thin layer of cooking oil and heat the grates until the oil smokes, then let them cool. This process helps maintain a non-stick surface and prevents rust.
- Storage: Store grates in a dry environment to prevent rust. If storing for extended periods, ensure they are clean and lightly oiled.
- Rust Prevention: Cast iron is prone to rust if not properly maintained. If rust appears, scrub it off with a wire brush, clean thoroughly, and immediately re-season the grates.
8. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Grates do not fit correctly. | Double-check the compatibility list and your grill's model number. Measure your grill's cooking area and compare it to the grate dimensions (17" x 7 1/2" each). Ensure emitter plates (if present) are correctly installed. |
| Food sticking to grates. | Grates may not be properly seasoned or need re-seasoning. Ensure grates are adequately preheated before placing food. Use a small amount of cooking oil on the food or grates if necessary. |
| Rust appearing on grates. | This is common for cast iron if not kept dry and seasoned. Scrub off rust with a wire brush, clean thoroughly, and immediately re-season the grates. Store in a dry place. |
| Uneven heating. | Ensure the grates are sitting flat and level. Check your grill's burners and heat tents for proper function and cleanliness. Allow sufficient preheating time. |
