Adjusting Simmer Low and Main Low Settings on
Surface Burner for Natural Gas
1. Remove the surface burner control knobs and bezels (oven
control knobs and griddle control knobs do not have to be
removed).
2. Locate the Simmer low-turndown adjustment screw through
the bezel on the left side of the ignition switch.

C. Main low-turndown adjustment screw (inside stem)
3. With the burner ON, and set to Simmer Lo, adjust the
simmer flame down to the proper BTU level. Using a
1/8" x 4¼" (3.2 mm x 108 mm) flat blade screwdriver,
turn the simmer low-turndown adjustment screw
counterclockwise until the flame becomes stable, does not
flicker, or appear to race around the burner. Once the flame
is stable, turn the burner rate to SIMMER HIGH setting. The
flame should increase to approximately 2X the flame height.
If not, the low-turndown may be able to be adjusted low and
still remain stable. Repeat this step for all surface burners,
except the grill burner.
NOTE: Use a knob to adjust the burner valve.
NOTE: If your range has the IR grill, then skip ahead to the
Convert IR Grill Burner section.
NOTE: Adjust each burner individually.
4. With burner OFF, using the same flat blade screwdriver, turn
the main low-turndown adjustment screw 120-135 degrees
counterclockwise. This will set the main low burner rate to a
proper level.
5. Replace the bezels using the 2 screws which attach to the
valve brackets.
6. Push the surface knobs onto the valve stems.
7. Replace burner grates.
Flame Height
The cooktop flame should be a steady blue flame approximately
1/4" (6.4 mm) high.
