Spider/Insect Screens
Your 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. Figure 4. This could result in a
fire in and around the air shutters, under the control
panel, causing serious damage to your barbecue.
Figure 4
Venturi

We recommend that you inspect the Spider/Insect
screens at least once a year. 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.

TROUBLESHOOTING
Problem
Burners burn with a yellow or orange flame, in
conjunction with the smell of gas.
Burner does not light, or flame is low
in HIGH position.
Experiencing flare-ups:
CAUTION: Do not line the bottom tray with
aluminum foil.
Burner flame pattern is erratic. Flame is low
when burner is on HIGH. Flames do not run
the whole length of the burner tube.
Inside of lid appears to be “peeling.”
(Resembles paint peeling.)
Check
Spider/Insect Screens for possible
obstructions. (Blockage of holes.)
Is fuel hose bent or kinked?
Does the Front burner light with a
match?
Are you preheating barbecue in the
prescribed manner?
Are the cooking grates and
Flavorizer Bars heavily coated with
burned-on grease?
Is the bottom tray "dirty" and not
allowing grease to flow into catch pan?
Are burners clean?
The lid is porcelain-on-steel, not
paint. It cannot “peel.”What you are
seeing is baked on grease that has
turned to carbon and is flaking off.
THIS IS NOT A DEFECT.
Cure
Clean Spider/Insect Screens
and burners. (See
Maintenance Section.)
Straighten fuel hose.
If you can light the Front
burner with a match, then
check the Crossover Ignition
System.(See Maintenance
Section.)
All burners on high for 10 to 15
minutes for preheating.
Clean thoroughly. (See
Cleaning Section.)
Clean bottom tray.
Clean burners. (See
Maintenance Section.)
Clean thoroughly. (See
Cleaning Section.)
If the problem cannot be corrected using these methods, please contact your Weber-Stephen Customer Service.
