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.
