Regulations and Directives

The design and operational characteristics of the Vitodens gas con-
densing boilers from Viessmann meet the requirements of EN 297.
They are CE-designated.
They may be installed in sealed heating systems with permissible flow
temperatures (= safety temperatures) up to 100 ºC compliant with
EN 12828. The maximum flow temperature is approx. 15 K below the
safety temperature.
Observe all standards and guidelines applicable to the installation and
operation of this system in your country.
Only qualified contractors must carry out the installation, the mains gas
and flue gas connections, the commissioning, the electrical connection
as well as general maintenance and repair work.
The installation of a condensing boiler may need to be notified to and
approved by your local gas supply utility.

In some regions, permits may be required for the flue system and con-
densate drain into the public sewer.
In some countries, the relevant flue gas inspector and water authorities
must be informed prior to commencing the installation.
We recommend that you carry out maintenance and cleaning proce-
dures annually. As part of the maintenance procedure, check the cor-
rect function of the entire system. Remedy any faults.
Condensing boilers must only be operated with specially designed,
tested and approved flue pipes.
Only recognised contractors may convert this boiler for use in countries
other than those stated on the type plate. That contractor must also
arrange the acceptance in accordance with the statutes of that coun-
try.
