Type Description
C1X Wall horizontal exhaust and intake. The inlet/outlet terminals must be concentric or close enough to be
undergo similar wind conditions (within 50 cm)
C3X Roof vertical exhaust and intake. Inlet/outlet terminals like for C12
C5X Wall or roof exhaust and intake separate or in any case in areas with different pressures. The exhaust and
intake must not be positioned on opposite walls.
C6X Intake and exhaust with separately certified pipes (EN 1856/1)
B2X Intake from installation room and wall or roof exhaust
IMPORTANT - THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION
For the connection of separate ducts, fit the unit with the following starting accessory:
Ø 81
fig. 19 - Starting accessory for separate ducts
Before installation, make sure the maximum permissible length has not been exceeded,
by means of a simple calculation:
1. Completely establish the layout of the system of split flues, including accessories
and outlet terminals.
2. Consult the table 6 and identify the losses in m
ponent, according to the installation position.
3. Check that the sum total of losses is less than or equal to the maximum permissible
length in table 5.

IMPORTANT - THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION
If the boiler is to be connected BLUEHELIX 25 K 50 to a collective flue or a single flue
with natural draught, the flue or chimney must be expressly designed by professionally
qualified technical personnel in conformity with the current regulations and be suitable
for sealed chamber units equipped with fan.

3.7 Condensate drain connection

The boiler has an internal trap for draining condensate. Fit the inspection union A and
the hose B, pressing it in. Fill the trap with about 0.5 L of water and connect the hose to
the disposal system.
