Tube Burner: The burners are made from heavy wall 304 stainless steel, but extreme heat and a corrosive environment can cause surface corrosion to occur. This can be removed with a brass wire brush.

CAUTION! Beware of Spiders.

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 reduces the likelihood of insects building nests inside the burner but does not entirely eliminate the problem. A nest or web can cause the burner to burn with a soft yellow or orange flame or cause a fire (flashback) at the air shutter beneath the control panel. To clean the inside of the burner, it must be removed from the gas grill: Remove the screw that attaches the burner to the back wall. Slide the burner back and upwards to remove. Cleaning: Use a flexible venturi tube brush to clean the inside of the burner. Shake any loose debris from the burner through the gas inlet. Check the burner ports and valve orifices for blockages. Burner ports can close over time due to cooking debris and corrosion, use an opened paperclip or the supplied port maintenance bit to clean them. Drill out blocked ports using this drill bit in a small cordless drill. The ports are easier to clean if the burner is removed from the grill, but it can also be done with the burner installed. Do not flex the drill bit when drilling the ports, as this will cause the drill bit to break. This drill is for burner ports only, not for the brass orifices (jets) which regulate the flow into the burner. Take care not to enlarge the holes. Ensure the insect screen is clean, tight, and free of any lint or other debris.

Reinstallation: Reverse the procedure to reinstall the burner. Check that the valve enters the burner when installing.

Warning! When reinstalling the burner after cleaning it is very important that the valve/orifice enters the burner tube before lighting your gas grill. If the valve is not inside the burner tube a fire or explosion could occur.
