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.
ƽ 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.
Main Burner Flame Pattern
The Weber Gas Barbecue burners have been factory
set for the correct air and gas mixture. The correct
flame pattern is shown.
1) Burner Tube
2) Tips occasionally flicker yellow
3) Light Blue
4) Dark Blue
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.
ƽCAUTION: 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.
