Replacing bypass nozzles
Use a flat-head screwdriver (no. 2) to unscrew the
1.
bypass nozzles. Remove the bypass nozzles.
Select the appropriate replacement bypass nozzles
2.
from the table. You can find additional information
about this in the section entitled "Technical data –
Gas" → Page 54.
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.
At this stage, it is important to test for leaks. You
5.
can find additional information about this in the sec-
tion entitled "Leak and function test" → Page 53.
Fitting the control panel
To reassemble, proceed in the reverse order of disas-
sembly.
Take hold of the front panel with both hands and
1.
carefully fit it into place. Ensure that the cables are
not damaged and the connections do not come
loose. Lower it slightly and insert it into the front
panel.
2.
Insert the screws (T15) (M4) that were removed
from the control panel.
Insert and tighten the screws (T20) that were re-
3.
moved from the front profiles on the right and left.
Attach the plastic covers.
Carefully install the hob. Ensure that the plastic
4.
parts which must remain underneath the screws do
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.
Install the burner bases in their respective positions
5.
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.
If one of the burners is a wok burner, screw in
‒
the four screw (M4) that were removed from the
wok burner.
Fit the pan support grids and the pan support
‒
racks. Ensure that the 80 mm pan support is fit-
ted on the auxiliary burner.
Carefully insert the knobs.
6.
At this stage, it is important to check that the gas
‒
burners are burning correctly. You can find addi-
tional information about this in the section en-
titled "Checking the correct burner behaviour"
→ Page 54.
Check whether the appliance is working correctly.

23.7 Leak test and function test
The leak test must be carried out by two people.
WARNING ‒ Risk of explosion!
Sparks, flames or open flames may cause explosions
during the leak and function test.
Ensure that no sparks are produced.
▶
Do not use any fire or naked flames.
▶
Only check the leak tightness using a suitable foam.
▶
Gas leak
¡ Close the gas connection locking device.
¡ Ventilate the relevant location sufficiently.
¡ Check the gas and nozzle connections once more.
¡ Repeat the leak test → Page 53.
Checking the gas connection
Open the gas connection shut-off.
1.
Apply suitable foam around the gas connection.
2.
a If dispersions and bubbles occur on the foamy sur-
face and these indicate that gas is escaping, follow
the instructions in the section entitled "What to do if
there is a gas leak" → Page 53.
Follow the same instructions for the part that is
3.
sealed with the blind plug.
Checking the cooker burner nozzles
Check the leak tightness of each nozzle.
Open the gas connection shut-off.
1.
To check, carefully cover the hole in the burner
2.
nozzle with your finger or a special device.
Apply suitable foam around the nozzle.
3.
Press on the burner knob and turn the knob anti-
4.
clockwise. Gas therefore comes to the nozzle.
a If dispersions and bubbles occur on the foamy sur-
face and these indicate that gas is escaping, follow
the instructions in the section entitled "What to do if
there is a gas leak" → Page 53.
Checking the bypass nozzles
Check the leak tightness of each bypass nozzle.
Open the gas connection shut-off.
1.
To check, carefully cover the hole in the burner
2.
nozzle with your finger or a special device.
Apply suitable foam around the bypass nozzle on
3.
