2.2 Positioning, installation
Installation conditions for balanced flue operation (boiler type C)
As device type C , C
13x 33x
C to TRGI '86/96, Vitodens can be
63x
installed for balanced flue operation,
independent of the size or ventilation of
the boiler room.
It may, for example, be installed in rooms
with personnel traffic or in living areas, in
ancillary rooms without ventilation, in
cupboards (open top) and niches without
maintaining minimum clearances to
combustible components as well as in
attic rooms (pitched attics and long pane
rooms of a roof) where the balanced flue
air supply/exhaust pipe can be directly
routed through the roof.
Since the flue pipe union for balanced
flue operation is surrounded by
2
combustion air (coaxial pipe), no
clearances towards combustible
components need to be maintained
(further details on page 100).
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
boiler room.
Electrical interlocks with extraction
devices (cooker hoods etc.) are not
required with balanced flue operation.

Install Vitodens 300 with 66 kW in
accordance with the Combustion Order
(FeuVo) [or local regulations] in a
separate boiler room. Fit the mains
electrical isolator outside the installation
room.
Ventilation air and exhaust air apertures
are required in accordance with TRGI
(see page 99).
