Procedure:

1.Close the main gas tap in the gas supply.

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 table above).

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 drawing 10).

-Seal this setting with lacquer.

-Remount the burner in reverse order.

-Open the main gas tap.

Conversion from LP-gas to natural gas:

-Put the pressure regulator into operation. To do this the temperature regulating knob should be pulled straight forward. Next the red plastic cover that is now visible, should be removed. Turn the ‘no pr’ (no pressure regulation) screw completely up (see drawing 10).

-Seal this setting with lacquer.

-Remount the burner in reverse order.

-Open the main gas tap.

-Set the correct burner pressure (see table above).

5.If necessary adjust the pilot correctly (see “Pilot adjustment”).

6.Fit the correct sticker from the conversion set on the appliance so that it is clear that the appliance has been converted and on which gas the appliance operates.
