Troubleshooting
Proper Burner Flame Pattern
The burners in your grill were factory set for the
correct air and gas mixture. When the burners are
performing correctly, you will see a specific flame
pattern. The tips may occasionally flicker yellow
(A), with a descending light blue (B) to dark blue
flame (C).
m WARNING: Do not attempt to make any repair to
gas carrying, gas burning, ignition components
or structural components without contacting
Weber-Stephen Products LLC, Customer Service
Department.
m CAUTION: The burner tube openings must be
positioned properly over the valve orifices.
Spider Screens
The combustion air openings of the burners(D)
are fitted with stainless steel screens to prevent
spiders and other insects from spinning webs
and building nests inside the venturi section of
the burners. These nests can obstruct the normal
gas flow, and can cause gas to flow back out of the
combustion air opening. 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, causing serious damage to your grill.
Additionally, dust and debris can accumulate on the
outside of the spider/insect screen and obstruct the
oxygen flow to the burners. Keep the spider screens
clean. Refer to “Cleaning the Spider Screens” in the
Product Care section.
