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

Design information

Installation conditions for room sealed operation (appliance type C)

The Vitodens can be installed as appliance type C
C , C or C to TRGl 2008, for room sealed operation independ-
63x 83x 93x
ent of the size and ventilation of the installation room.
It may, for example, be installed in recreation rooms, in other living
spaces, in ancillary 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. Since the flue pipe connection piece for room sealed operation is
surrounded by combustion air (coaxial pipe), no clearances towards
combustible parts need to be maintained (for further details, see the
technical guide "Flue systems for the Vitodens").
The installation area must be safe from the risk of frost.
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 Combustion Order (FeuVo) [Germany] boilers
from 50 kW must be installed in a separate room [observe local regu-
lations]. Fit the mains isolator outside the installation room.
Operation of the Vitodens in wet areas
The Vitodens is approved for installation in wet areas (IP rating:
IP X 4D, splashproof)
Electrical connection
The power supply must comply with the requirements of your local
power supply utility and current VDE [or local] regulations (a: ÖVE
regulations).
Protect the power cable with a fuse with a max. rating of 16 A.
We recommend installing an AC/DC-sensitive RCD (RCD class B) for
DC (fault) currents that can occur with energy efficient equipment.
Make the power supply (230 V~, 50 Hz) via a permanent connection.
Connect the supply cables and accessories at the terminals inside the
boiler.
Allow cables/leads in the shaded area to protrude at least 800 mm from
the wall (see diagram):

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 garages, maintain a clearance between
the floor and the burner of at least 500 mm. Install a frame or deflector
(provided on site) to protect the boiler against mechanical damage.
Safety equipment for the installation room
Viessmann heat sources are tested and approved in accordance with
all safety regulations and are therefore fail-safe. Unpredictable, exter-
nal factors may, in the rarest of cases, lead to the potentially harmful
escape of carbon monoxide (CO). For this case, we recommend using
a CO limiter. This can be ordered as a separate accessory (part no.
7499 330).
When installing the Vitodens in wet areas, observe the safety zones
and minimum wall clearances according to VDE 0100 [or local regu-
lations]. The Vitodens 200-W may be installed in safety zone 1.
