All conversions require the air/gas ratio to be set correctly in accordance with the gas that will be used. The procedure for setting the air/gas ratio is included in these instructions.

Conversion of the setting ring

1.Switch off the electrical supply to the appliance

2.Close the gas tap on the gas supply to the appliance

3.Remove the front cover of the appliance

4.Disconnect the coupling above the gas valve and turn the gas mixing pipe backwards

6.Reconnect the coupling above the gas valve and open the gas tap

7.Check the gas connections for tightness/leaks

8.Switch on the electrical supply to the appliance

9.Check, and when needed change the gas/air ratio (CO2% ). See table below and text at the next page.

CAUTION

It is not possible to adjust the CO2 level at high setting. When the CO2 level at high setting is not within the prescribed tolerance band, please contact your supplier. For adjusting the CO2 level at low setting see the table below and the text on the next page.

10.Apply a LPG sticker to the nut at the upper side of the gas valve

11.Apply a LPG sticker to the appliance plate (lower left corner) in such a way that the G20 data is covered.

12.Remount the front cover of the appliance.

Conversion Instructions Natural Gas G20 to Natural Gas G25

Setting gas/air adjustment

Setting by measurement of the CO2 content of the combustion gases

A.Cover screw

B. Adjusting screw for low position

1.	Switch the appliance off with the the on/off	key (		-	on	display)
2.	Unscrew the CO2 measuring nipple and connect the measuring hose.
3.	Remove the front panel from the appliance.
4.	Switch the appliance on with the on/off key.
5.	Adjust the appliance to the highest power by simultaneously pressing the keys
	and on the operating panel until an	H	appears on the display.
6.	Check if the CO2 level is in accordance with the value mentioned in the table on
	the previous page.

CAUTION

It is not possible to adjust the CO2 level at high setting.

When the CO2 level at high setting is not within the prescribed tolerance band please contact your supplier.

7.Note the measured CO2 value and adjust the appliance to the lowest power by

simultaneously pressing the keys and on the operating panel until an

L appears on the display.

8.Measure the CO2 value. If the CO2 value does not correspond with the value in the table on the previous page proceed with setting as follows:

9.Remove the cover cap (A, Torx T15)

10.Adjust the set screw (B) to the correct CO2 value (clockwise higher and anticlockwise lower).

11.After measurement and setting replace the cover cap (A) and close the CO2 measurement nipple.

12.Adjust the appliance to the maximum power by simultaneously pressing the keys and (2 x) on the operating panel until an H appears on the display.
