m DANGER
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.
ANNUAL MAINTENANCE
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
