General Maintenance
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 Venturi(1). 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 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.
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 throughout
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.
