Before proceeding with the adjustment, SHUT OFF THE GAS SUPPLY TO THE
APPLIANCE PRIOR TO DISCONNECTING THE ELECTRICAL POWER.
If the information in this manual is not followed exactly, fire or shock may result
causing property damage or personal injury.
3) Adjust the burner’s control valve to MIN to see that the flame continues to wrap around the burner. Blow out the flame, or
use a quick fan motion from a writing tablet or piece of cardboard to extinguish the flame. Observe the burner’s ability to reig
nite and wrap around (also called “carry-over”) the burner within several seconds. This flame “carry-over” is essential for
proper burner ignition and reignition.
4) If the flame performance is not acceptable it may be necessary to readjust the valve screw (fig. 2 and 3 on page 34) for a
burner that does not have sufficient carry-over of the flame.
STEP 3
Screwdriver for valve screw setting:
A flat-head screwdriver is used to reposition the valve screws for minimum flow settings on the knobs.
Setting valve screws on ranges:
1) SHUT OFF THE GAS SUPPLY TO THE APPLIANCE AND DISCONNECT THE ELECTRICAL POWER.
2) Remove knob from the valve stem by slowly pulling knob straight out, away from the control panel.
3) For Natural Gas ranges, note the original position of the slot in the valve screw. This can be done by engaging the
screwdriver’s blade in the screw slot and marking the screwdriver’s handle to indicate the starting position of the valve
screw. With the screwdriver still engaged, carefully rotate the valve screw counter-clockwise (CCW) 1/4 turn (or 90
degrees) from its original position. Repeat this procedure to adjust the setting for each valve screw. For LP Gas ranges or an
appliance that has been converted to LP Gas, adjustment is rarely necessary.
4) Turn on the gas and electrical power to the appliance. Reevaluate the flames. Repeat Steps 1 through 3 if further
adjustment is necessary.
