Siting Conditions For Room Sealed Operation (Appliance Type C) - Viessmann VITODENS 200-W Type B2HA Technical Manual

Design information

Siting conditions for room sealed operation (appliance type C)

The Vitodens can be installed as equipment type C
C , C or C to TRGl 2008, for room sealed operation inde-

pendent of the size and ventilation of the installation room.
Installation room
It may, for example, be installed in recreation rooms, in other living
spaces, in adjacent rooms without ventilation, in cupboards (open at
the top) and recesses, without maintaining minimum clearances to
combustible parts, as well as in attic rooms (pitched attics and long
panes) where the balanced flue pipe can be routed directly through
the roof.
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.
Vitodens 200-W from 60 kW
In accordance with the German Combustion Order (FeuVo), boilers
from 50 kW must be installed in a separate room [check local regula-
tions]. Fit the mains isolator outside the installation room.
Appropriate ventilation air and extract air apertures are required in
accordance with TRGI (see the technical guide on flue systems for
the Vitodens).
Connection on the flue gas side
The flue pipe should be designed to be as short and straight as pos-
sible.

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 of the chimney. Sulphur and soot deposits cause
faults. If thorough cleaning is not possible, a balanced flue pipe must
be laid through the shaft. Alternatively, a separate balanced flue can
be routed. Viessmann accepts no liability for damages caused by a
failure to observe these stipulations.
Operation of the Vitodens in wet rooms
■ Room sealed operation:
The Vitodens is approved for installation in wet rooms (IP rating:
IP X4, splashproof).
The boiler may be installed in safety zone 1 if hosed water (e.g.
from massage showers) is prevented.
■ Open flue operation:
The Vitodens must not be installed in safety zone 1 or safety zone
2.
When installing the Vitodens in wet rooms, observe the safety zones
and minimum wall clearances according to VDE 0100 [or local regu-
lations] (see also "Electrical safety zone").

Using third party flue systems
Every approved flue system can be used for type C6. These flue
systems are not tested together with the boilers and do not have
system certification in accordance with EC Gas Appliances Directive
2009/142/EC. When using, follow the Viessmann design specifica-
tions in the flue system technical guide for appliance types C

information.
If aluminium flue pipes are used, a condensate trap must additionally
be installed above the boiler flue connection.
Installation in a garage
Tests carried out by the Gaswärme-Institut e.V., Essen, have con-
firmed that the Vitodens is suitable for installation in garages.
When installing this boiler in a garage, maintain a clearance between
the floor and the burner of at least 500 mm. Install a frame or deflec-
tor (provided on site) to protect the boiler against mechanical dam-
age.
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. This can be ordered as a separate acces-
sory.

Electrical equipment in rooms containing a bathtub or a shower must
be installed in such a way that users cannot be exposed to danger-
ous body currents. VDE 0100 specifies that cables supplying perma-
nently installed consumers in zones 1 and 2 should only be run verti-
cally and routed into the equipment from the back.
