Operating Your Grill
Pre-Lighting Checks:
- Ensure all gas connections are tight and free of leaks.
- Confirm the gas supply valve is open.
- Keep the grill lid open during ignition.
Ignition Procedure:
- Turn all burner control knobs to the OFF position.
- Slowly open the main gas supply valve.
- Push in and turn one main burner control knob to the HIGH position.
- Press the electronic igniter button repeatedly until the burner ignites. You should hear a clicking sound and see a flame.
- Once the first burner is lit, you can ignite adjacent burners by pushing in and turning their respective knobs to HIGH.
- For the side burner or rear burner, follow a similar push-and-turn ignition process.
Temperature Control:
Your Regal S 590 Pro features 5 stainless steel Dual-Tube burners, designed for even heat distribution. The reversible stainless steel V-grids offer versatility for searing or basting. The Flav-R-Wave cooking system vaporizes drippings, enhancing flavor and reducing flare-ups. Adjust the control knobs to achieve your desired cooking temperature. The built-in thermometer on the lid provides accurate temperature readings.



Maintenance and Care
Regular cleaning and maintenance will extend the life of your Broil King grill and ensure optimal performance.
- Cooking Grids: Clean cooking grids after each use with a grill brush. For stubborn residue, preheat the grill for 10-15 minutes on high, then brush clean.
- Flav-R-Wave System: Periodically remove and clean the Flav-R-Wave components. Scrape off any accumulated grease or food particles.
- Grease Tray: Regularly check and empty the grease tray to prevent overflow and potential flare-ups.
- Burners: Inspect burner ports for blockages (e.g., spider webs, food debris). Use a wire brush or paperclip to clear any obstructions.
- Exterior: Clean stainless steel surfaces with a stainless steel cleaner and a soft cloth. For painted surfaces, use mild soap and water.
Troubleshooting
If you encounter issues with your grill, consult the following common troubleshooting tips:
- Burner Not Lighting: Check if the gas supply is open. Ensure the igniter is clicking and sparking. Verify that burner ports are not clogged.
- Uneven Heat: Clean the Flav-R-Wave components and burner ports. Ensure all burners are functioning correctly.
- Excessive Flare-Ups: Reduce heat, trim excess fat from food, and clean the cooking grids and Flav-R-Wave system to remove grease buildup.
- Low Flame: Check the gas supply level. Ensure the regulator is not in bypass mode (reset by turning off gas, disconnecting regulator, waiting 1 minute, reconnecting, and slowly opening gas).
