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.

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.

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.

WARNING: Do not enlarge the burner ports when cleaning.
