Operation Of The Vitodens In Wet Areas; Electrical Connection - Viessmann VITODENS 200-W Technical Manual

Design information
(cont.)
It may, for example, be installed in recreation rooms, in other living
space, in ancillary rooms without ventilation, in cupboards (open at the
top) and recesses without maintaining minimum clearances to com-
bustible parts as well as in attic rooms (pitched attics and ancillary
rooms) where the balanced flue pipe can be directly routed through
the roof. Since the flue pipe connecting piece for balanced flue oper-
ation is surrounded by combustion air (coaxial pipe), no clearances
towards combustible parts need to be maintained (for further details,
see the technical guide "Flue gas systems for the Vitodens").
The installation location must be safe from the risk of frost.
Provide a condensate drain and a blow-off line for the safety valve in
the installation room.

Operation of the Vitodens in wet areas

The Vitodens is approved for installation in wet areas (e.g. bath or
shower rooms) (protection IP X4 D, splash-proof).
When installing the Vitodens in wet areas, observe the safety zones
and minimum wall clearances according to VDE 0100 [or local regu-
lations] (see also "Electrical protection area"). The Vitodens may be
installed in safety zone 1, if hosed water (e.g. through massage
showers) is prevented.

Electrical connection

Ensure the power supply complies with the requirements of your local
power supply utility and current VDE [or local] regulations.
Protect the power cable with a fuse with a maximum 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).

Electrical interlocks for extractors (extractor hoods, etc.) are not
required with balanced flue operation.
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. Protect the boiler on site
with a bracket or deflector against mechanical damage.
Electrical equipment in rooms containing a bathtub or a shower must
be installed in such a way that users cannot be exposed to dangerous
body currents.
The VDE 0100 specifies that cables to supply permanently installed
consumers in zones 1 and 2 will only be run vertically and fed into the
equipment from the back.
