MAINTENANCE
Spider/Insect screens
Your 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 5. This could result in a fire in and around the air shutters, under the control panel, causing serious damage to your barbecue.
Venturi
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 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.
