Air Shutter Adjustment
This appliance is shipped from the factory with air
shutters adjusted for use with Natural Gas. If further
adjustment is necessary, or to reset for use with LP,
adjust air shutters as follows:
Grill Burner and Surface Burner Cartridge Air
Shutters
(See Illustrations “A” & “B”)
The left hand air shutter controls the rear half of the
burner. The right hand shutter controls the front half.
Access to air shutters on the surface burner cartridge may
be found through openings on the bottom of the cartridge
housing.
Slide air shutters backward or forward to increase or
decrease the size of the air opening. Air shutters fit
snugly, so a screwdriver blade may be required to make
this adjustment (see illustration).
Observe change in flame appearance as the air shutter is
moved. Adjustment is satisfactory when a clearly defined,
even blue flame results at the high flame setting. The
snug fit of the air shutter assures it will remain positioned
correctly.

On any burner, closing the air shutter too far will cause
the flame to become soft and yellow tipped. Opening the
air shutter too wide will cause the flame to blow away
from the burner ports. Proper adjustment will produce a
sharp, clearly defined, even blue flame.

Low Flame Adjustment
(See Illustration “C”)
This appliance is shipped from the factory with low and
medium flame settings adjusted for use with Natural Gas.
If further adjustment is necessary, or to readjust for use
with LP, proceed as follows:
1. Light burner and set control knob for low flame.
2. Remove control knob from valve stem.
CAUTION
NEVER USE A METAL BLADE TO PRY KNOB OFF.
IF KNOB CANNOT BE EASILY REMOVED, TUCK THE
FOLDS OF A CLOTH DISHTOWEL UNDER THE KNOB
AND PULL THE TOWEL UPWARD WITH STEADY,
EVEN PRESSURE.

at center of valve stem and engage blade with slot in
adjusting screw.
4. Turn center stem adjusting screw to set flame size.
S
clockwise to reduce.

counterclockwise to increase.
5. Replace control knob when adjustment is completed.
Proper adjustment will produce a stable, steady blue
flame of minimum size. The final adjustment should be
checked by turning knob from high to low several times
without extinguishing the flame.
This adjustment, at low setting, will automatically provide
the proper flame size at medium setting.
