Table. 4 - Typology
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.

Type Description
C2X Intake and exhaust in common flue (intake and exhaust in same flue)
C4X Intake and exhaust in common and separate flues, but undergoing similar wind conditions
C8X Exhaust in single or common flue and wall intake
B3X Intake from installation room by means of concentric duct (that encloses the exhaust) and exhaust in
common flue with natural draught
IMPORTANT- THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION
C93 Exhaust to a vertical terminal and intake from existing flue.
If the boiler is to be connected BLUEHELIX PRO C to a collective flue or to 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
IMPORTANT
The boiler has an internal trap for draining condensate. Install the inspection union "A"
and hose "B" by press fitting. Before commissioning, fill the trap with approx. 0.5 L of
water and connect the hose to the disposal system.
B
ATTENTION: THE UNIT MUST NEVER BE OPERATED WITH THE TRAP
EMPTY!
OTHERWISE THERE IS A DANGER OF SUFFOCATION DUE TO THE EMIS-
SION OF THE COMBUSTION FUMES.
