Inspection and cleaning of the Spider/Insect screens
To inspect the Spider/Insect screens, remove the control panel. If there is dust or dirt on
the screens, remove the burners for cleaning the screens.
Brush the Spider/Inspect screens, lightly, with a soft bristle brush (i.e. an old toothbrush).
ƽ CAUTION: Do not clean the Spider/Insect screens with hard
or sharp tools. Do not dislodge the Spider/Insect screens or
enlarge the screen openings.
Lightly tap the burner to get debris and dirt out of the burner tube. Once the Spider/
Insect screens and burners are clean replace the burners.

SPIDER /INSECT SCREENS
gas barbecue, as well as any outdoor gas appliance, is a target for spiders
and other insects. They can nest in the venturi section (1) of the burner tubes. This
blocks the normal gas ﬂ ow, and can cause the gas to ﬂ ow back out of the combustion
air opening. This could result in a ﬁ re in and around the combustion air openings, under
the control panel, causing serious damage to your barbecue.
The burner tube combustion air opening is ﬁ tted with a stainless steel screen (2) to
prevent spiders and other insects access to the burner tubes through the combustion air
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 ﬂ ames appearing yellow and lazy.
2) Barbecue does not reach temperature.
3) Barbecue heats unevenly.
4) One or more of the burners do not ignite.
Failure to correct the above mentioned symptoms may result
in a ﬁ re, which can cause serious bodily injury or death, and
cause damage to property.
MAIN BURNER CLEANING PROCEDURE
Turn off the gas supply.
Remove the manifold (See “Replace Main Burners”).
Look inside each burner with a ﬂ ashlight.
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 oriﬁ ces at the base of the valves. Use a Steel bristle brush to clean outside of
burners. This is to make sure all the burner ports are fully open.
ƽ CAUTION: Do not enlarge the burner ports when cleaning.
