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 cold down
completely.
To Adjust:
1. Light grill using information in the "Outdoor Grill Use" section.
2. Observe flame to determine which burners need adjustment
and how the flame is acting.
3. Turn off the valve and wait until grill and burners cool
completely.
4. Remove grill grates and flame tamers.
5. Remove the 2 screws and cotter pin that hold the burner in
place. Remove gas burner from the grill.
