Design information

Operation of the Vitodens in wet rooms

■ Room sealed operation:
The Vitodens is approved for installation in wet rooms (IP rating:
IP X4 D, splashproof).
The boiler may be installed in safety zone 1 if hosed water (such
as 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").

Electrical connection

The power supply must comply 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 10 A.
We recommend installing an AC/DC-sensitive RCD (RCD class B)
for DC (fault) currents that can occur with energy efficient equip-
ment.
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 equipment in rooms containing a bathtub or a shower must
be installed in such a way that users cannot be exposed to danger-
ous shock currents. VDE 0100 specifies that cables supplying per-
manently installed consumers in zones 1 and 2 should only be run
vertically and routed into the equipment from the back.
