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.
NOTE:
The rotisserie burner cannot be adjusted.
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 HI setting are acceptable
as long as no carbon or soot deposits appear. The flames should be
approximately 1" (2.5 cm) high.
1" (2.5 cm)
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
completely.
