Weber Spider Stopper Guards Installation Instructions

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.

For Genesis 1, 2, 3, 4, 5 and Perma-Mount Gas Barbecues

27-39900 Rev. 3/90

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 5

Remove the manifold bracket: Place your hand
underneath the bracket. Lift the bracket, manifold and
cooking box as a unit and unhook the bracket from the
frame brace. Figure 4. Remove the bracket from the
manifold.

Note - Your Weber Genesis Gas Barbecue may not
have a manifold bracket. Manifold brackets may be
obtained from:

Step 6

Remove the manifold

Unscrew the thumb screws that hold the manifold to the
cooking box, and pull the manifold out of the burners and
set it down carefully. Figure 5.

Note - It may be necessary to use a pair of pliers to
loosen the thumb screws.

Step 7

Using a flashlight, look inside each burner for any
obstructions. Figure 6.

Step 8

Use the burner cleaning tool or a straight piece of wire to
clean the burner tubes of any obstructions, if necessary.
Figure 7.

Step 9

Install the Manifold

Insert the valves into the ends of the burner tubes and
install the manifold thumb screws; hand tighten. If you
have trouble installing the manifold, check the burner tube
alignment: Remove the cooking grills and Flavorizer Bars
and make sure the slots on the burner tubes are installed
under the heads of the guide screws. These screws
should not be fully tightened. Figure 8.
