Burner Adjustment
Grill burner air adjustment
Each grill burner is tested and adjusted at the factory prior to
shipment; however, variations in the local gas supply or a conversion
from one gas to another may make it necessary to adjust the burners.
The flames of the burners (except the rotisserie burner) should be
visually checked and compared to that of the drawing in Fig.12.
Flames should be blue and stable with no yellow tips (LP units may
have some yellow tipping), excessive noise or lifting. If any of these
conditions exist, check if the air shutter or burner ports are blocked
by dirt, debris, spider webs, etc. Proceed with air shutter adjustment.
The amount of air which enters a burner is governed by a metal cup
at the inlet of the burner called an air shutter. It is locked in place
by a screw which must be loosened prior to lighting the burner for
adjustment.
IMPORTANT!
Before lighting, inspect the gas supply piping or hose prior to turning the gas “on”. If there is evidence
of cuts, wear, or abrasion, it must be replaced prior to use.
Grill burner flame height
Before beginning, ensure the grill is off and cool. To access the grill burner air shutters, first remove
the grates and radiants from the firebox, then remove the grill burner using instructions shown on
page 35. With a screw driver, loosen the lock screw on the face of the air shutter slightly so that the
air shutter can be adjusted.
To adjust
1
Be careful as the burner may be very hot.
2
If the flame is yellow, indicating insufficient air, turn the air shutter counter-clockwise to allow more air
to the burner.
3
If the flame is noisy and tends to lift away from the burner, indicating too much air, turn the air shutter
clockwise.
Note: reinstall the U-burner, ensuring the burner is level. Light the burner and check the flame.
If the color of the flame is blue and the height is stable, remove the burner and tighten the air
shutter screw. If the flames show instability or an inconsistent color, repeat the above procedure to
readjust the air shutter.
Low flame setting adjustment
The valves on the grill feature an adjustable low setting. Due to fluctuations in gas pressure, heating
value or gas conversion, you may feel it necessary to increase or decrease gas flow in the low
position. We do not recommend adjusting the infrared rotisserie burner.
To adjust
1
Light the burner.
2
Turn the control knob to the lowest setting (counter-clockwise).
3
Remove the knob.
4
While holding the valve shaft with pliers, insert a thin, flat tipped
screwdriver into the shaft and while viewing the burner adjust to a
minimum stable flame.
y
For safety reasons the flame must never extend beyond the bottom of the cooking utensil. Never allow
flames to curl up the side of the pan.
y
Utensils which conduct heat slowly (such as glass-ceramic) should be used with medium to low flames.
If you are cooking with a large amount of liquid, a slightly larger flame can be used.

Side burner flame height
The correct height of the flame mainly depends on the size of the
bottom of the cooking utensil, the material of the cooking utensil,
the amount and type of food and the amount of liquid in the
utensil. Following are some basic rules for selecting flame height.
