Area 2
■ Cupboards (open at the top)
■ Recesses without compulsory clear-
ance towards combustible materials
■ Attic rooms (pitched attics and long
panes) where the balanced flue can be
routed directly through the roof
Since the flue pipe connection for room-
sealed operation is surrounded by com-
bustion air (coaxial pipe), no clearances
towards combustible materials need 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.

areas, observe the safety zones and
minimum wall clearances according to
VDE 0100 [or local regulations] (see also
"Electrical safety zone"). The Vitodens
may be installed in area 1 if hosed water
(e.g. from massage showers) is preven-
ted.
