8 ADJUST BURNER FLAMES
Normally, burners do not need further
adjustment. Make adjustments only when
necessary.
A. Turn on the gas. Plug in electrical cord.
B. Turn all burners on highest setting and
check the flames. They should be blue in
color. When using LP gas, the flames may
have some yellow tipping at the ends of the
flame. Foreign particles in the gas line may
cause an orange flame at first, but this will
soon disappear.
C. Turn the burner knob to “LO” while
observing the flame.
Adjust the setting of the upper row of flames
using the valve bypass screw as follows:
Adjustments must be made with two other
burners in operation on a medium setting.
This prevents the upper row of flames from
being set too low, resulting in the flame
being extinguished when other burners are
turned on.
D. To adjust the flame, remove the knobs. Insert
a small flat-blade screwdriver into the hole
in the center of the valve stem to engage
screw.
• If the flames are too small or flutter, turn the
screw counterclockwise.
• If the flames are too large, turn the screw
clockwise.
E. Make the adjustment by slowly turning the
screw until flame appearance is correct.
