General Maintenance
Weber Spider/Insect Screen
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 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.

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 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 may cause serious bodily injury or death, and cause damage to property.

If the flames do not appear to be uniform the length of the burner tube, follow the burner cleaning procedures.
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 brass 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.
Replacing Main Burners
1)Your Weber Gas Barbecue must be OFF and cool.
2)Turn gas OFF at source.
3)Remove control panel: take off the burner control knobs. Remove the screws holding the control panel in place. Lift off the control panel.
