there is a gas leak" → Page 39.
20.7 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.
