Installation conditions for balanced flue operation (boiler type C)
As device type C , C
13x 33x
C to TRGI '86/96, the 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 spaces,
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.
The flue pipe union for balanced flue
operation is surrounded by combustion
2
air (coaxial pipe). Consequently,
clearances towards combustible
components are not required (further
details on page 128).
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.
Vitodens 300 with 66 kW
Install the Vitodens 300 with 66 kW in
accordance with the Combustion Order
(FeuVo) [or local regulations] in a
separate boiler room. Fit the mains
isolator outside the installation room.
Ventilation air and extract air apertures
are required in accordance with TRGI (see
page 127).
