Correct flame formation
Burner
The flame formation and temperature development must be
checked for each burner after the appliance is converted to a
different gas type.
In the event of a problem, compare the nozzle values to the
values in the table.
Only for models without safety pilot
1.
Ignite the hob burner as described in the operating
instructions.
2.
Check the large and small flames for the correct flame
formation. The flame must burn evenly and continuously.
3.
Using the burner knob, switch quickly between the large and
small frame. Repeat this process a few times. The gas flame
must not flicker or go out.
Only for models with safety pilot
1.
Ignite the hob burner as described in the operating
instructions.
2.
Turn the burner knob to the small flame setting.
Check whether the ignition is activated by holding the knob in
the "small flame" position for approximately 1 minute.
3.
Check the large and small flames for the correct flame
formation. The flame must burn evenly and continuously.
4.
Using the burner knob, switch quickly between the large and
small frame. Repeat this process a few times. The gas flame
must not flicker or go out.
Oven
Lower gas burner or grill burner (optional)
1.
Ignite the lower gas burner as described in the operating
instructions.
2.
Check the flame formation with the oven door open:
The flame must burn evenly throughout (it may be slightly
uneven in the first few minutes, but after a few minutes, the
flames should burn constantly).
3.
To check that the thermocouple is functioning correctly, let
the appliance run for a few minutes.
If necessary, check the settings. If it is not functioning
correctly, replace the bypass screw in the burner.
