Conversion Instructions for Item #0503231
Main Burner Conversion
1. Pull off the R-pins and take the main
burners out. Adjust main burners' air
shutters by loosening the air shutter
screws. (Fig. 89)
2. The settings are:
1/4 in. open for LP gas.
1/16 in. - 1/8 in. open for NG gas.
You need to adjust the openings before you
put the burners back in the burner box.
(Fig. 90)
3. Remove the LP orifices first with the orifice
removal tool, then install the NG orifice.
Make sure you are using the correct orifice,
marked "1.37". (Fig.91)
When this step is completed, install the
main burners back to the firebox and
secure to the bracket with the R-pins.
Make sure the orifices are aligned with the
burners and the ignition pins are installed
in their original positions. Check the sparks
before operating the grill.
