To Convert Surface Burners from Natural Gas to
Propane
1. If the burner grates are installed, remove them.
2. Remove burner cap.
3. Remove the burner base by first removing (2) T-20 screws.
4. Apply masking tape to the end of a 1/4" (6.4 mm) nut driver
to help hold the gas orifice spud in the nut driver while
changing it. Insert nut driver into the gas opening and press
down onto the gas orifice spud and remove by turning the
gas orifice spud counterclockwise and lifting out. Set gas
orifice spud aside.
5. Replace with correct Propane gas orifice spud. See the
"Propane Gas Orifice Spud/Hood Chart".
Use the following chart to find the exact orifice spud
placement.

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.

B. 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 clockwise until
the flame height is below the bottom of the cap. If the flame
becomes unstable and flickers or appears to race around the
burner, the adjustment is too low and the screw should be
adjusted counterclockwise until the flame 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 flat 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.
