Adjusting Simmer Low and Main Low Settings on
Surface Burner for Propane
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.
3. With the burner ON, and set to Simmer Lo, adjust the
simmer ame down to the proper BTU level. Using a
1/8" x 4¼" (3.2 mm x 108 mm) at blade screwdriver, turn
the simmer low-turndown adjustment screw clockwise until
the ame height is below the bottom of the cap. If the ame
becomes unstable and ickers or appears to race around the
burner, the adjustment is too low and the screw should be
adjusted counterclockwise until the ame is 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 at blade screwdriver, turn
the main low-turndown adjustment screw 120-135 degrees
clockwise. 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.
