KEEPING YOUR
WEBER
®
GAS BARBECUE
IN TIP-TOP SHAPE
To keep your Weber
®
gas barbecue performing as safely
and efficiently as on day one, we strongly recommend
that you inspect and clean the spider/insect screen(s) and
burner tube(s) at least once a year. Below is important
information about these two areas of the barbecue that
should undergo annual maintenance.
If you observe an incorrect flame pattern or blocked
burner port, proceed to the “BURNER TUBE
CLEANING OR REPLACEMENT” instructions on the
following page.
BURNER FLAME PATTERN
The burner tube(s) in your Weber
®
gas barbecue was/
were factory set for the correct air and gas mixture. The
correct flame pattern is shown in illustration and described
below:
• Burner tube(s) (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 screen(s) has/have become dirty or blocked.
WEBER

SPIDER/INSECT SCREEN(S)
The combustion air opening(s) of the burner tube(s) (5)
is/are fitted with stainless steel screen(s) to help prevent
spiders and other insects from spinning webs and
building nests inside the venturi section (6) of the burner
tube(s). These nests can obstruct the normal gas flow,
and can cause gas to flow back out of the combustion
air opening(s) (7). Symptoms of this kind of obstruction
include the odour of gas in conjunction with burner flames
that appear yellow and lazy. This obstruction could result
in a fire in and around the gas valve(s), causing serious
damage to your barbecue (8).
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 barbecue, the burner
tube ports will become dirty. Blocked and dirty ports can
restrict full gas flow. Following are ways to determine
whether burner tube ports are dirty or blocked.
• Barbecue does not reach desired temperature
• Barbecue heats unevenly
• One or more of the burner(s) do not ignite
