Turn the grill burner controls to the off position. Close the main valve on the propane cylinder, and disconnect it from the grill.
Remove the burner plates, cooking grids and sub floor from the grill. Consult the manufacturer's instructions for removing the briquettes. The cooking plates can be easily removed by lifting them from the grill.
Burners are blocked by fat drippings that fall from meat as it cooks and grease runoff from the grill. Visually examine the burners and tubes for raised hardened drippings, baked-on black-or-brown-colored grease and any excess dirt or debris.
Return the briquettes and cooking grids. Hook up the propane cylinder. Keep the main valve closed when it is not in use.
