1. Remove the pan supports and lift the burners out of
their housing. The burner consists of two separate
parts (see pictures).
2. Unscrew the nozzles using a 7 mm socket spanner.
Replace the nozzles with models that are configured
for use with the new type of gas (see Table 1). The
two nozzles have the same hole diameter.
3. Replace all the components by completing the
above operations in reverse order.
• Adjusting the burners' primary air :
Does not require adjusting.
• Setting the burners to minimum:
1. Turn the tap to the low flame position.
2. Remove the knob and adjust the adjustment screw,
which is positioned in or next to the tap pin, until the
flame is small but steady.
3. Having adjusted the flame to the required low
setting, while the burner is alight, quickly change the
position of the knob from minimum to maximum and
vice versa several times, checking that the flame
does not go out.
