In rooms where air contamination from halogenated hydrocar-
bons or organosilicon compounds (e.g. siloxanes) may occur,
such as hairdressing salons, printing shops, chemical cleaners, labo-
ratories, etc., the Vitodens may only be operated as a room sealed
system.
If in doubt, please consult us.
Never install the Vitodens in areas subject to very dusty conditions.
The installation location must be kept free from frost and must be
adequately ventilated.
Provide a condensate drain and a discharge pipe for the safety valve
in the installation room.
The max. ambient temperature of the system must not exceed
35 °C.
If these instructions are not observed, any consequential appliance
damage directly related to any of these causes is excluded from our
warranty.
a When installing in Austria, observe all current safety regulations
as defined by ÖVGW-TR Gas (G1), ÖNORM, ÖVGW, ÖVE and
locally applicable standards.
Multi boiler systems with flue systems under negative pressure
Systems with several Vitodens with separate hydraulic connections
require a flue gas cascade suitable for negative pressure or individ-
ual flue gas routing for each boiler.
Installation room
Permissible:
■ Siting gas equipment on the same floor
■ Living space with interconnected room air supply
■ Ancillary rooms with interconnected room air supply (larders, base-
ments, utility rooms, etc.)
■ Ancillary rooms with vents to the outside: Ventilation air/extract air
150 cm
2
or 2 × 75 cm
2
each at the top and bottom of the same
wall, up to 35 kW
■ Attic rooms, but only with adequate minimum chimney height, acc.
to DIN 18160 – 4 m above inlet (negative pressure operation).
Not permissible:
■ Stairwells and communal hallways. Exception: In detached and
two-family houses of low height, top edge of floor in the top storey
< 7 m above ground level.
■ Bathrooms and toilets without outside windows with shaft ventila-
tion
■ Rooms where explosive or flammable materials are stored
■ Rooms that are ventilated mechanically or via individual duct sys-
tems to DIN 18117-1
Observe all local fire regulations.
Connection on the flue gas side
The connection piece to the chimney should be as short as possible.
Therefore position the Vitodens as close to the chimney as possible.
The flue should be designed to be as straight as possible. If bends
are unavoidable, do not arrange these one after the other. The entire
flue gas path must be able to be checked and cleaned as required.
No special protective measures or clearances towards combustible
objects, such as furniture, packaging or similar, need to be taken/
observed. The surface temperatures of the Vitodens and the flue
system do not exceed 85 °C at any point.
For further details, see the technical guide on flue systems for the
Vitodens.
Extractors
When installing appliances with extraction to the outside (cooker
hoods, extractor fans, etc.), ensure that air extraction will not create
negative pressure inside the installation room. A return flow of flue
gases could result if the ventilation system and the Vitodens are
operated simultaneously. In such cases, install an
interlock circuit .
Safety equipment for the installation room
Viessmann heat generators are tested and approved in accordance
with all safety regulations and are therefore fail-safe. Unpredictable
external factors may, in the rarest of cases, lead to the potentially
harmful escape of carbon monoxide (CO). For this case, we recom-
mend using a CO limiter.

The Vitodens can be installed for
room sealed operation independ-
ent of the size and ventilation of the installation room.
Installation room
Suitable siting locations include:
■ Recreational rooms and other living spaces
■ Unventilated ancillary rooms
■ Cabinets (open at the top)
■ Recesses without compulsory clearance towards combustible
materials
■ Attic rooms (pitched attics and long panes) where the balanced
flue pipe can be routed directly through the roof
The installation room must be free from the risk of frost.
The max. ambient temperature of the system must not exceed
35 °C.
Provide a condensate drain and a discharge pipe for the safety valve
in the installation room.
Electrical interlocks for extractors (extractor hoods, etc.) are not
required with room sealed operation.
Connection on the flue gas side
The flue should be designed to be as short and straight as possible.
If bends are unavoidable, do not install them directly one after
another. The entire flue gas path must be able to be checked and
cleaned as required.
Since the flue pipe connection for room sealed operation is surroun-
ded by combustion air (coaxial pipe), no clearances towards com-
bustible materials need be maintained.
Ventilation air ducts with which oil or solid fuel boilers were previ-
ously used must not contain any sulphur or soot deposits on the
inner surfaces.
Sulphur and soot deposits cause operating faults.
If thorough cleaning is not possible, a balanced flue pipe must be
laid through the shaft. Alternatively, lay separate ventilation air and
flue gas pipes.
Viessmann accepts no liability for damages caused by a failure to
observe these stipulations.
Close off and seal any other connection apertures with appropriate
materials.
This does not apply to any cleaning or inspection apertures that are
provided with chimney cleaning covers and that are identified with an
appropriate test mark.
For further details, see the technical guide on flue systems for the
Vitodens.
