details on the rating plate. If pressure is
too high, install a pressure regulator.
Attention: If the measured gas flow
•
pressure deviates from the values in
the table, the gas supplier must be
informed:
If the connected gas flow pressure is
outside the permitted range, the
appliance must not be operated. The gas
supply to the appliance will have to be
sealed.
Attention! In order to ensure that the
