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 connection of the separate ducts, fit the unit with the following starting accessory:
Ø 81
fig. 12 - Starting accessory for separate ducts
Before proceeding with 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 meq (equivalent metres) of every com-
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.
