Weber Spider Stopper Guards User manual

Note - Figures in these instructions are intended to
represent all Genesis Gas Barbecue models, your
barbecue may differ from these illustrations.
Your Weber®Genesis®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 1. This could result in a fire in and around the air
shutters, under the control panel, causing serious
damage to your barbecue. We have developed the
Weber Spider Stopper Guards to significantly
reduce the chance of this happening to your Weber
Genesis Gas Barbecue.
The Weber Spider Stopper Guard fits tightly around the
air shutter section of the burner tube and the valve,
thereby preventing spiders and other insects access to
the burner tubes through the air shutter openings.

Installation Instructions
We recommend that you inspect the Weber Spider
Stopper Guards at least once a year. Also inspect and
clean the Spider Stopper Guards 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.
WARNING: Make sure gas supply is turned off; i.e.:
LP cylinder valve is closed or natural gas supply
shut-off turned off and hose disconnected from the
Quick Disconnect.
Note - You should inspect the burners for spider webs
and other obstructions before installing your new
Weber Spider Stopper Guards. To inspect the burners,
you must remove the manifold. The following
instructions show you how to both remove the manifold
and install the Weber Spider Stopper Guards.
Step 1
For LP units only, disconnect the gas hose from the LP
tank.
Step 2
Pull off all burner control knobs. Remove control panel.
Step 3
Remove the igniter.
DANGER
Failure to correct these symptoms may
result in a fire which can cause serious
bodily injury or death, and cause damage
to property.

Step 4
• On Genesis 4, 5 and Perma-Mount Gas Barbecue
models with a FlameCheck Safety System you must
disconnect the capillary tube from the FlameCheck
valve. Figure 3.
Note - The end of the capillary tube and the bottom of
the FlameCheck valve must be kept free of dirt and oil
(even oil from your fingers). Be careful when
disconnecting the capillary tube.
• On units with a side burner, disconnect the side
burner hose from the side burner fitting on the manifold
and remove the side burner. Figure 3.

Step 15
Check the fit of the Spider Stopper Guards
Slightly rotate the Spider Stopper Guards, if necessary,
so that the seams are in line with the Venturi fins. There
should be no gaps in the seams or in the fit around the
burners and valves. Figure 11.

Refer to your Owner’s Manual.
WARNING: You should check for gas leaks every
time you disconnect and reconnect any gas fitting.
Step 17
Install burner control knobs and control panel.
Inspection and cleaning of the Weber Spider
Stopper Guards
To inspect the Spider Stopper Guards, remove the control
panel, and look to see if they have dust or dirt on their
outside surfaces. If dust or dirt has accumulated, brush it
off with a soft bristle brush (for example, an old tooth-
brush). Check that there are no gaps in the Spider
Stopper Guards’ seams or in the fit around the burners or
valves. See Figure 11.

DANGER
Do not use an open flame to check for
gas leaks. Be sure there are no sparks or
open flames in the area while you check
for leaks. This may result in a fire or
explosion which can cause serious bodily
injury or death and damage to property.
