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 grate and sear plates.
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.
Main burner
Side burner
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.
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 sear plates.
5. Remove the 2 screws that hold the burner in place. Remove 
gas burner from the grill. 
6. If flame is yellow (not enough air), turn air shutter adjustment 
screw counterclockwise.
If flame is noisy or lifts away from burner (too much air), turn 
air shutter adjustment screw clockwise.
Adjustment should be made clockwise or counterclockwise 
from 
¹⁄₈" (3.2 mm) to ¹⁄₄" (6.4 mm).
7. Replace gas burner, sear plates and grates.
8. Light grill using information in the “Outdoor Grill Use” section. 
See “Burner Flame Characteristics.”
Low Flame Adjustment
If flame goes out on the “LO” setting, the low flame setting must 
be adjusted.
1. Turn off the valve and wait until grill and burners are cool.
2. Remove grill grates and sear plates.
3. Light grill using information in the “Outdoor Grill Use” section.
4. Turn burner to its lowest setting and remove knob.
5. Hold valve stem with pliers and insert a small flat-blade 
screwdriver into the shaft.
6. Watch the flame and slowly turn the screwdriver 
counterclockwise.
7. Adjust flame to minimum stable flame.
8. Replace the control knob and turn off the burner.
9. Repeat steps 3 through 8 for each burner if needed.

cooled.
