BURNER - The burner is made from heavy wall 304 stainless steel, but due to the extreme heat and corrosive environment, surface corrosion will occur. Use a brass wire brush to remove surface corrosion. Clean any blocked ports using an opened paper clip. Do not enlarge the burner ports. Spiders and insects are attracted to the smell
of propane and natural gas. The burner is equipped with an insect screen on the air shutter, which will reduce the likelihood of insects building nests inside the burner, but does not entirely eliminate the problem. The nest or web will cause the burner to burn with a soft yellow or orange flame or cause a fire (flashback) at the air shutter underneath the control panel. To clean the inside of the burner, it must be
removed from the gas grill. Remove the screw(s) located either in the center of the burner on 308 models, or above the burner to the left and right of the centre of the burner on 450 models. Lift back of burner upwards to remove. Use a flexible venturi tube cleaning brush to clean out the inside of the burner. Shake any loose debris out of the
burner, through the gas inlet. Ensure that the insect screen is clean,Screw 
tight, and free of any lint or other debris. Check also that the valve
orifices are clean. Do not enlarge the orifices.
ALUMINUM CASTINGS - Clean castings periodically with warm soapy water. Aluminum will not rust, but due to high temperatures
and weathering, oxidation can occur on aluminum surfaces. This will appear as white spots on the castings. To refinish the castings, clean them and sand lightly with fine sandpaper. Wipe surface to remove any residue, and paint with high temperature barbecue paint. Protect surrounding areas from
