4. Safety Information
- Always ensure the grill is completely cool and disconnected from its fuel source before attempting any replacement or maintenance.
- Wear appropriate personal protective equipment, such as gloves, to prevent cuts or scrapes from sharp edges.
- Keep all parts away from children and pets during installation.
- Refer to your original grill's instruction manual for specific safety warnings and disassembly/assembly procedures.
5. Setup and Installation
Follow these general steps for replacing your grill components. Specific disassembly and reassembly may vary slightly based on your exact Charbroil Advantage 2-Burner model. Always consult your grill's original manual for detailed instructions.
- Preparation: Ensure the grill is off, cool, and the gas supply is turned off and disconnected. Remove existing grill grates, heat tents/plates, and burner tubes.
- Install Burner Tubes: Carefully place the new stainless steel burner tubes into their designated positions. Ensure they are properly seated over the gas orifices.
- Install Crossover Tube: Attach the adjustable stainless steel crossover tube between the burner tubes. Adjust its length (from 5 to 9 inches) as needed to ensure a secure fit and proper flame transfer.
- Install Ignitors: Connect the new ignitors according to your grill's original wiring. Ensure a secure connection for reliable ignition.
- Place Heat Plates: Position the stainless steel heat plates above the burner tubes. Ensure they cover the burners adequately to distribute heat evenly and protect them from drippings.
- Position Grill Grates: Place the matte cast iron grill grates onto the grill frame. Ensure they are stable and correctly aligned.
- Leak Test: After reassembling, reconnect the gas supply and perform a leak test using a soapy water solution on all gas connections before lighting the grill.

6. Operating Instructions
Once all replacement parts are installed and a leak test has been successfully performed, your grill is ready for use. For optimal performance and longevity of the new parts, consider the following:
- Initial Burn-Off: Before cooking, preheat your grill on high for 15-20 minutes to burn off any manufacturing residues from the new components.
- Seasoning Cast Iron Grates: For the matte cast iron grates, it is recommended to season them before first use and periodically thereafter. Apply a thin layer of high-heat cooking oil (like flaxseed or grapeseed oil) to the grates, then heat the grill to a high temperature until the oil smokes and cures. This creates a non-stick surface and prevents rust.
- Even Heat Distribution: The new burner tubes and heat plates are designed to provide consistent, evenly-spread heat across the cooking surface. Monitor your grill's temperature to adjust for desired cooking results.
7. Maintenance and Cleaning
Regular maintenance extends the life of your grill replacement parts and ensures safe operation.
- Grill Grates:
- After each use, clean the cast iron grates with a grill brush while they are still warm.
- For stubborn residue, allow grates to cool, then wash with warm soapy water. Dry thoroughly and re-season if necessary to prevent rust.
- Heat Plates and Burner Tubes:
- Periodically, remove the grates and heat plates. Use a plastic scraper or brush to remove any accumulated grease or food debris from the heat plates and burner tubes.
- Ensure burner ports are clear of obstructions. Use a wire brush or a stiff wire to clean any clogged ports.
- The stainless steel components are designed to be rust-resistant and easy to clean. Wipe with a damp cloth as needed.
- General Cleaning: Keep the interior of your grill clean to prevent grease fires and maintain efficiency.
8. Troubleshooting
If you encounter issues after installing the replacement parts, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Burners not lighting | Ignitor not sparking, gas flow issue, clogged burner port. | Check ignitor connection and spark. Ensure gas tank is open and full. Clean burner ports. Verify crossover tube alignment. |
| Uneven heating | Clogged burner ports, improperly seated heat plates. | Clean burner ports. Ensure heat plates are correctly positioned over burners. |
| Grates rusting | Lack of seasoning, improper drying after cleaning. | Re-season cast iron grates. Ensure grates are thoroughly dried after washing. |
If problems persist, consult your original grill manufacturer's manual or contact Hiorucet customer support.
