Replacing bypass nozzles
1.
Use a flat-head screwdriver (no. 2) to unscrew the
bypass nozzles. Remove the bypass nozzles.
2.
Select the appropriate replacement bypass nozzles
from the table. You can find additional information
about this in the section entitled "Technical data –
Gas" →
.
3.
Check that the seals on the bypass nozzles are
seated correctly and work properly. Only use by-
pass nozzles with absolutely faultless seals.
4.
Insert the new bypass nozzles and tighten them se-
curely. Ensure that all bypass nozzles have been
fastened to the correct taps.
5.
At this stage, it is important to test for leaks. You
can find additional information about this in the sec-

Fitting the control panel
To reassemble, proceed in the reverse order of disas-
sembly.
1.
Take hold of the front panel with both hands and
carefully fit it into place. Ensure that the cables are
not damaged and the connections do not come

Insert the screws (T15) (M4) that were removed
from the control panel.
3.
Insert and tighten the screws (T20) that were re-
moved from the front profiles on the right and left.

not fall out. Unscrew the two screws (T20) on the
front left and right on the hob. If there are any
burner connection screws, screw them all into the
cooktop.
5.
Install the burner bases in their respective positions
according to their size. Make sure that the ignition
plugs are placed in the appropriate openings next
to the burner bases. Place the enamelled burner
lids onto the centre of the appropriate lower parts of
the burner and, in doing so, note the sizes.
