You have to remove items 7, 8, and 9 from the grill. These parts just lift off and you should clean them while you have them off.
Grasp the burners at the rear and lift the rear of the burners off the support about 4-5 inches. Pull the burners to the rear of the grill and they will slide off the orifice hood of the burner valve. Note how the burners slide over the orifice and rest on the burner support for installing the new burners.
