2.Demount the burner (see “Cleaning”).

3.Replace the injector of the main burner and the pilot burner with the correct injectors from the conversion set (see tables above).

4.a Conversion from natural gas to LP- gas

-Put the pressure regulation of the gas control block out of operation. To do this the temperature regulating knob should be pulled straight forward. Turn the ‘no pr’ (no pressure regulation) screw down tight (see Figure 10).

-Seal this setting with lacquer.

-Remount the burner in reverse order.

-Open the main gas tap.
