SEALED INSTALLATION (TYPE C)
Coaxial flues (Ø 60/100)
Coaxial flues can be oriented in whatever direction is
most convenient for the room, provided the maximum
lengths specified alongside are respected.
9
Ensure that the flue gas vent pipe has a 1% slope
towards the boiler.
9
Use of flue pipes longer than the maximum speci-
fied alongside leads to a loss of heat output from
the boiler (see table alongside).
9
The boiler automatically adapts its ventilation sy-
stem to suit the type of installation and the length
of the flue. Never obstruct or partly choke the com-
burent air intake pipe.
9
Use only flues specifically designed for use with
condensing boilers . Follow the instructions provi-
ded in the flue pipe kit to install the flues.
B23P Upstream fan. Comburent air intake
directly from the room where the boiler
is installed. Flue gas vent via horizontal
or vertical flues designed to operate at
positive pressure, with air ventilation to
room .
B53P Upstream fan. Comburent air intake directly
from the room where the boiler is installed.
Flue gas vent via horizontal or vertical flues
designed to operate at positive pressure, with
air ventilation to room.
C13 Concentric wall vent. Twin flue pipes can also
be used, but the wall through-pipes must
be concentric or located close enough to be
subjected to similar wind conditions.
C23 Concentric vent to shared flue (air intake and flue
gas vent via same concentric pipe).
C33 Concentric roof vent. Outlets as for C13.
C43 Vent and air intake via shared twin pipes,
subjected to similar wind conditions.
C53 Separate wall or roof vent and air intake, in areas
of different pressure but never on opposite
walls.
C63 Upstream fan. Comburent air intake and flue gas
vent without flue terminals.
C83 Upstream fan. Comburent air intake through wall
and flue gas vent to roof.
In Italy, refer to DPR 412 and UNI CIG 7129 standard.
9
Maximum straight length is the maximum length of
the flue without bends, terminals or joints.
