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 2 screws located above the burner to the left and

right of the centre of the burner. 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, tight, and free of any lint or other debris. Check also that the

valve orifices are clean. Do not enlarge the orifices. Re-install the burner.Screw Check that the valve enters the burner when installing. Replace burner cover

and mounting screws to complete installation.

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 over-spray. Follow curing directions found on the can.
