(cont.)
■ Cupboards (open at the top)
■ Recesses without compulsory clear-
ance towards combustible materials
■ Attic rooms (pitched attics and long
panes) where the balanced flue pipe
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 on flue systems for the
Vitodens.
The installation room must be safe from
the risk of frost.
