21.6 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 41.
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 41.
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 41.
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 41.
Checking the lower oven gas burner nozzle
Check the leak tightness of each bypass nozzle.
Open the gas connection shut-off.
1.
To check, carefully cover the hole for the burner
2.
nozzle in the oven's lower gas burner with your fin-
ger or a special device.
Apply suitable foam around the nozzle.
3.
Press the function control knob for the oven and
4.
turn the knob anti-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 41.
21.7 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
cooker burner
Ignite the gas cooker burners in accordance with
1.
the instructions in the operating manual.
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
1 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.
Checking the correct burner behaviour for the
lower oven gas burner
Ignite the lower oven gas burner in accordance with
1.
the instructions in the operating manual.
→ "Basic operation", Page 19
Open the oven door and observe the flame.
2.
a The flame must burn evenly.
a The flame may fail during the first few minutes. How-
ever, the flame must stabilise after a few minutes.
Switch on the appliance for a few minutes to check
3.
whether the thermocouple becomes sufficiently
warm.
a Adjust the settings, if required. If the bypass nozzle
on the burner is faulty, replace this.
