CLEANING THE SPIDER/INSECT SCREENS
Your Ducane
®
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 flow, and can cause the gas to flow back out 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 (2) 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. Also,
inspect and clean the Spider/Insect screens if any of the following symptoms occur:
1) The smell of gas in conjunction with the burner flames appearing yellow and lazy.
2) Barbecue does not reach temperature.
3) Barbecue does not heat evenly.
4) One or more of the burners do not ignite.
ƽ 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 Ducane
®
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 main
burner cleaning procedure.
CLEANING THE MAIN BURNER
• To clean the gas ports of your main burners use a stiff bristle brush to brush the
openings.
• Refer to: Inspection and Cleaning of the Spider/Insect Screens for the removal
of the burner tube.
• You can now lift the burner tube out of the burner box and inspect inside 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 openings at the ends of the burners.
• Check and clean the valve orifices on the valves. Use a steel bristle brush to
clean the outside of the burners. This is to make sure that all burner ports are fully
open.
ƽ WARNING: Do not enlarge the burner ports when cleaning.
9) If there is dust or dirt on the screens, brush the Spider/Insect screen(s), 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.
10) If the Spider/Insect screen becomes damaged or cannot be cleaned, call Ducane
Customer Service at 1-800-382-2637 for replacement parts.
11) To reassemble, reverse steps 2 through 10.
