Maintenance and Care
Regular cleaning and maintenance will ensure the longevity and optimal performance of your NXR side burner.
- Stainless Steel Surfaces: Clean with a mild soap and water solution, then rinse thoroughly and dry with a soft cloth to prevent water spots. For stubborn stains, use a non-abrasive stainless steel cleaner. Always wipe in the direction of the grain.
- Cooking Grates: After each use, clean the grates with a grill brush while they are still warm. For a deeper clean, remove the grates and wash with warm, soapy water.
- Burner Ports: Periodically inspect burner ports for blockages (e.g., food debris, insect nests). Use a wire brush or a small wire to clear any obstructions.
- Burner Caps: Remove and clean burner caps regularly to ensure proper flame distribution.
- Lid: Wipe the lid clean after each use to remove grease and food residue.
Troubleshooting
If you encounter issues with your side burner, refer to the following common problems and solutions:
- Burner Not Lighting:
- Check if the gas supply is turned on and the gas tank (if applicable) has fuel.
- Ensure the burner control knob is fully pushed in and turned to the IGNITE/HI position.
- Verify that the igniter is sparking. If not, check the igniter electrode for damage or blockages.
- Clean burner ports and tubes to ensure no obstructions are preventing gas flow.
- If using a propane tank, ensure it is not empty and the regulator is properly connected.
- Uneven Flame:
- Clean burner ports and ensure they are free of debris.
- Check for proper alignment of the burner tube with the gas valve orifice.
- Gas Odor:
- Immediately turn off the gas supply.
- Do not operate the appliance.
- Check all gas connections for leaks using a soapy water solution. Bubbles indicate a leak.
