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).
A
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 burners.
Additionally, dust and debris can accumulate
on the outside of the spider/insect screen and
obstruct the oxygen flow to the burners.
