Check And Adjust The Burners - KitchenAid OUTDOOR GRILL Manual

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 the burners
cool down completely.
