How do I avoid Performance issues, deterioration and maintenance issues, as well as fire and safety hazards?

The only way to avoid all of the issues listed above is to remove your BBQ’s Double Burners or Tube Burners one to three times a season and perform regular maintenance and safety checks. Your BBQ will provide you with many years of reliable performance as long as regular maintenance is performed.

General Burner Maintenance

1. Remove your Cuisinart® cooking grates and heat distribution plates to reveal the burners.
2. To remove Double Burners or Tube Burners you must first remove the hardware used to assemble the burner into the burner box.
3. Remove Double Burner or Tube Burner.
4. Brush the outer parts of the burner using a wire or brass bristled brush, paying particular attention to the burner port holes.
5. Using a flexible wire, open paper clip, or a drill bit, probe each port hole to clear it of grime and rust.
   
   
   

   CAUTION

   Do not use anything larger in diameter than the port hole itself as this may cause damage to the burner port holes.

   
   
6. Using a Venturi tube brush, or bottle cleaning brush, clean the interior of the burner. Special care should be taken to make sure the brush passes through the entire burner interior.
7. Lightly tap the burner to remove any residue. A garden hose can be used to flush out any debris from within the burner, but NO WATER must be allowed to remain on the interior of the burner, as this may cause corrosion or lighting issues.
8. Visually check the gas jets at the end of each of the valves for dirt, dust and spider webs. Clean them if necessary.
9. Remove and clean the Easy Clean Grease tray and Grease cup.
10. Re-install the Double Burners or Tube Burners using hardware removed. Ensure that the burners are installed correctly with the Venturi tube seated correctly over the valve gas jet, and firmly in place.
11. Re-install the heat distribution places and cooking grates
