OPERATION WITH DIFFERENT TYPES OF GAS
CONVERSION FROM NATURAL GAS TO LIQUID GAS
Proceed with burner jets replacement. Insert the diaphragm (I) included in the kit. Also replace the spring (C)
under the rod of the coil (E), checking that it is assembled the right way round. Switch the bridge on the
modulation board from NATURAL GAS to the B-P position.
Then adjust as indicated in the paragraph "ADJUSTMENTS", page 66.
For jets diameter and operating gas pressure see the table here-under.
