Preface
Dear Customer,
Your Buderus
500 Series
wall-mounted condensing gas sys-
tem boiler has been designed and built in accordance with
state-of-the-art technological standards and the recognised
safety rules. Special focus has been placed on operator con-
venience in this respect.
Carefully read the safety instructions and operating manual to
ensure safe, economic and ecologically beneficial use of the
unit.
Due to the high efficiency of the boiler a plume of water vapour
may form at the terminal during operation. This is normal.
