Installation Instructions
Before beginning, ensure your grill is completely cool and disconnected from its gas supply. It is advisable to wear protective gloves during the installation process.
- Remove Old Components:
Carefully remove the cooking grates and heat tents from your grill. Then, detach the old, rusted burners and crossover tubes. Note the position and connection points of the igniters. Old parts may be corroded and require gentle force or rust penetrant for removal.

- Clean Grill Interior:
Thoroughly clean the interior of your grill, removing any debris, grease, or rust flakes. A wire brush can be useful for this step.
- Install New Burners:
Place the new stainless steel pipe burners into their respective slots. Ensure they are properly seated and aligned with the gas orifices at the back of the grill. Secure them if necessary, typically with a cotter pin or screw at the front.
- Connect Crossover Tubes:
Adjust the length of the new crossover tubes to span between the burners. Connect them to the designated points on each burner. These tubes facilitate flame transfer between burners.
- Install Igniters:
Attach the new grill igniters to their corresponding burners. Ensure the igniter electrodes are positioned correctly to spark near the gas outlet of the burner. Connect the igniter wires to the main ignition module.

- Place Heat Plate Shields:
Position the new heat plate shields (flavorizer bars) directly over the installed burners. These shields protect the burners from dripping grease and help distribute heat evenly.

- Replace Cooking Grates:
Once all components are securely in place, reinstall your cooking grates.
- Test Grill:
Reconnect the gas supply and perform a leak test. Then, carefully light each burner to ensure proper ignition and even flame distribution. Adjust burner positions if necessary to achieve optimal performance.

Operation
After successful installation of the replacement parts, your Charbroil grill should operate as intended, providing consistent heat for your outdoor cooking needs. Always follow the original grill manufacturer's safety guidelines for operation, including proper ventilation and gas handling procedures.
- Ensure all gas connections are tight and free of leaks before lighting.
- Always open the grill lid before igniting the burners.
- Start with one burner, ignite it, then proceed to others.
- Monitor flame appearance; a healthy flame is typically blue with a yellow tip.
Maintenance
Regular maintenance of your grill's internal components will significantly extend their lifespan and ensure optimal performance. Although these parts are made of stainless steel, proper care is essential.
- Regular Cleaning: After each use, clean the heat plate shields and burners to remove grease and food residue. Accumulated debris can lead to corrosion and uneven heating.
- Inspect for Rust: Periodically inspect the burners, heat plates, and crossover tubes for signs of rust or corrosion. While stainless steel is resistant, prolonged exposure to moisture and food acids can cause surface rust.
- Ventilation: Ensure proper ventilation around your grill to prevent moisture buildup, which can accelerate corrosion.
- Cover Your Grill: Use a grill cover when not in use to protect it from the elements.
Troubleshooting
- Burner Not Lighting:
- Check gas supply: Ensure the gas tank is open and has sufficient fuel.
- Igniter issue: Verify the igniter electrode is clean and properly positioned near the burner's gas port. Check igniter wire connections.
- Gas orifice blockage: Clean any debris from the burner's gas orifice.
- Uneven Heating:
- Clogged burner ports: Clean the small holes along the burner tubes to ensure even gas flow.
- Heat plate positioning: Ensure heat plate shields are correctly seated over the burners.
- Crossover tube issue: Verify crossover tubes are properly connected and not obstructed.
- Premature Rusting:
- Ensure regular cleaning and drying of components.
- Store grill in a dry environment or use a high-quality grill cover.
- Avoid using abrasive cleaners that can damage the stainless steel surface.
