8BURNER - The burner is made from heavy wall 304 stainless steel, but due to theextreme heat and corrosive environment, surface corrosion will occur. Use a brass wirebrush to remove surface corrosion. Clean any blocked ports using an opened paperclip. Do not enlarge the burner ports. Spiders and insects are attracted to the smell ofpropane and natural gas. The burner is equipped with an insect screen on the airshutter, which will reduce the likelihood of insects building nests inside the burner, butdoes not entirely eliminate the problem. The nest or web will cause the burner to burnwith a soft yellow or orange flame or cause a fire (flashback) at the air shutterunderneath the control panel. To clean the inside of the burner, it must be removedfrom the gas grill. Remove the 2 screws located above the burner to the left and right ofthe centre of the burner. Lift back of burner upwards to remove. Use a flexible venturitube cleaning brush to clean out the inside of the burner. Shake any loose debris out ofthe burner, through the gas inlet. Ensure that the insect screen is clean, tight, and freeof any lint or other debris. Check also that the valve orifices are clean. Do not enlargethe orifices. Re-install the burner. Check that the valve enters the burner wheninstalling. Replace burner cover and mounting screws to complete installation.ALUMINUM CASTINGS - Clean castings periodically with warm soapy water.
