Weber® Spider /Insect screens
Your Weber® gas barbecue, as well as any outdoor gas appliance, is a target for spiders and other insects. They can nest in the venturi section(1) of the burner tubes. This blocks the normal gas flow, and can cause the gas to flow back out of the air shutter. This could result in a fire in and around the air shutters, under the control panel, causing serious damage to your barbecue.
(1)
The burner tube air shutter is fitted with a stainless steel screen(1) to prevent spiders and other insects access to the burner tubes through the air shutter openings.

We recommend that you inspect the Spider/Insect screens at least once a year. (See Section “Annual Maintenance”.) Also inspect and clean the the Spider/ Insect screens if any of the following symptoms should ever occur:
1)The smell of gas in conjunction with the burner flames appearing yellow and lazy.
2)Barbecue does not reach temperature.
3)Barbecue heats unevenly.
4)One or more of the burners do not ignite.
DANGER
Failure to correct the above mentioned symptoms may result in a fire, which can cause serious bodily injury or death, and cause damage to property.
Annual Maintenance
Inspection and cleaning of the Spider/Insect screens To inspect the spider/insect screens, remove the control panel. If there is dust or dirt on the screens, remove the burners for cleaning the screens. Refer to Maintenance, Replacing Main Burners. Brush the spider/inspect screens, lightly, with a soft bristle brush (i.e. an old toothbrush).
CAUTION: Do not clean the spider/insect screens with hard or sharp tools. Do not dislodge the spider/insect screens or enlarge the screen openings.

Main Burner Cleaning Procedure
Turn off the gas supply. Remove the manifold. Look inside each burner with a flashlight.
Clean the inside of the burners with a wire (a straightened- out coat hanger will work). Check and clean the air shutter opening at the ends of the burners. Check and clean the valve orifices at the base of the valves. Use a Steel bristle brush to clean outside of burners. This is to make sure all the burner ports are fully open.
CAUTION: Do not enlarge the burner ports when cleaning.
