ANNUAL MAINTENANCE
KEEPING YOUR WEBER® GAS GRILL IN TIP-TOP SHAPE
mDANGER
Failure to correct any problems described on this page may result in a fire, which can cause serious bodily injury or death, and cause damage to property.
To keep your Weber® gas grill performing as safely and efficiently as on day one, we strongly recommend that you inspect and clean the spider/insect screens and burner tubes at least once a year. Below is important information about these two areas of the grill that should undergo annual maintenance.
If you observe an incorrect flame pattern or blocked burner ports, proceed to the “Burner Tube Cleaning or replacement” instructions on the following pages.
BURNER FLAME PATTERN
The burner tubes in your Weber® gas grill were factory set for the correct air and gas mixture. The correct flame pattern is shown in illustration and described below:
•Burner tube (1)
•Tips occasionally flicker yellow (2)
•Light blue (3)
•Dark blue (4)
Check burner flame pattern. If the flames do not match the above description, it could be an indication that the spider/ insect screens have become dirty or blocked.
WEBER® SPIDER/INSECT SCREENS
The combustion air openings of the burner tubes (5) are fitted with stainless steel screens to help prevent spiders and other insects from spinning webs and building nests inside the venturi section (6) of the burner tubes. These nests can obstruct the normal gas flow, and can cause gas to flow back out of the combustion air openings (7). This could result in a fire in and around the burner valves, under the control panel, causing serious damage to your grill.
NOTE: If a spider/insect screen becomes damaged or cannot be cleaned, please contact the Customer Service Representative in your area using the contact information on our web site. Log onto www.weber.com®.
BURNER TUBE PORTS
Over time, from repeated use of the grill, the burner tube ports will become dirty. Blocked and dirty ports can restrict full gas flow. Following are ways to determine whether burner tubes are dirty or blocked.
•Gas is smelled in conjunction with burner flames that appear yellow and lazy
•Grill does not reach desired temperature
•Grill heats unevenly
•One or more of the burners do not ignite
