ADJUST THE LOW FLAME (SIMMER)
SETTING
The top burner valves have low flame/simmer
adjustment screws in the center of the control shafts.
A flashlight may be needed to locate the screw. A small,
thin-blade screwdriver (approximately 1/8
″
blade width)
is needed to access the screw.
Light two other burners and set the knobs to a
medium to high setting.
Light the burner to be adjusted and turn the knob
to LOW.

Conversion Instructions
Remove the knob and insert a screwdriver into
the valve shaft.
Turn the adjustment screw until the flame reaches the
desired size.
Perform a flame stability test.
Flame Stability Test
Test 1: With the downdraft vent fan on HI, turn the
burner knob from HI to LOW quickly. If the LOW
flame goes out, increase the flame size and test
again.
Test 2: With the burner on the LOW setting, open
and close the cabinet door under the cooktop. If
the flame is extinguished by the air currents
created by the door movement, increase
the flame height and test again.
Flame Recheck
After the adjustment is made, turn all burners off. Ignite
each burner individually. Observe the flame at the HI
position. Rotate the valve to the LOW position and be
sure the flame size decreases as the valve is rotated
counterclockwise.
