Check and Adjust the Burners
The burners are tested and factory-set for most efficient
operation. However, variations in gas supply and other
conditions may make minor adjustments to air shutter or low
flame setting necessary. It is recommended that a qualified
person make burner adjustments.
Checking and adjusting the grill burner flames requires
removing the grates and flame tamers.
Burner Flame Characteristics
The flames of the grill burners and side burners (on some
models) should be blue and stable with no excessive noise or
lifting (LP gas flames will have a slightly yellow tip). A yellow
flame indicates not enough air. If flame is noisy or lifts away
from the burner, there is too much air. Some yellow tips on
flames when the burner is set to HIGH setting are acceptable
as long as no carbon or soot deposits appear. The flames
should be approximately 1" (2.5 cm) high.
Check that burners are not blocked by dirt, debris, insect nests,
etc., and clean as necessary. If they are clean, adjust air
shutters as needed.
IMPORTANT: Before adjusting air shutters, let burners cool
down completely.
