holder.
Carefully insert the knobs.
7.
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 51.
Check whether the appliance is working correctly.

23.6 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 51.
Checking the gas connection
1.
Open the gas connection shut-off.
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 51.
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 51.
Nozzle values for the auxiliary burner
Note the following information for the gas types that are listed in the table for some burners.
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.
the burner that is to be checked.
Press on the tap spindle and turn it anti-clockwise.
4.
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 51.
23.7 Checking the correct burner behaviour
Check the burning and soot formation of each burner
after the product has been converted to a different gas
type. If there is a problem, compare the nozzle values
with the values in the table.
Checking the correct burner behaviour of the
cover burner
1.
Ignite the gas cooker burners in accordance with
the instructions in the operating manual.
→ "Operating the hotplate", Page 17
Set the gas cooker knob to the small flame setting.
2.
Check whether the flame safety system is working
by keeping the flame at the "small flame" setting for
one minute.
Check that the burners are burning correctly with
3.
both large and small flames.
a The flame must burn evenly and steadily.
Turn the burner knob back and forth quickly
4.
between the large flame setting and the small flame
setting. Repeat this process several times.
a The gas flame must not flicker or go out.
