4. Switch on the power to the entire cascade
5. After the "FH" procedure, check the correct operation of the cascade:
• Module 1: arrow symbol at top left of the display
• Module 2: arrow symbol at bottom right of the display
• Module 3: arrow symbol at bottom right of the display
• Module 4: arrow symbol at top right of the display
If this does not occur, disconnect the power and check the wiring in fig. 23.
Settings
All adjustments must be made on all the modules.
Possible faults
If the electrical connection of a module is disconnected for any reason, module 1 will ac-
tivate fault F70.
If the electrical connection of a module is disconnected for any reason, the next module
will activate fault F71.
3.5 Fume ducts
The unit is a "C type" with sealed chamber and forced draught, the air inlet and fume out-
let must be connected to one of the following extraction/suction systems. The unit is ap-
proved to operate with all the Cxy and Bxy flue configurations given on the dataplate
(some configurations are given by way of example in this section). Some configurations
may be expressly limited or not permitted by law, standards or local regulations. Before
proceeding with installation, check and carefully observe the above-mentioned prescrip-
tions. Also, comply with the provisions on the positioning of wall and/or roof terminals and
the minimum distances from windows, walls, ventilation openings, etc.
B
This C-type unit must be installed using the inlet and fume outlet ducts supplied
by the manufacturer in accordance with UNI-CIG 7129/92. Failure to use them
automatically invalidates every warranty and relieves the manufacturer of any
liability.
For fume exhaust pipes longer than 1 metre, during installation take in account
A
the natural expansion of the materials when the boiler is operating.
To prevent deformations, leave an expansion space of approx. 2 ÷ 4 mm for every metre
of pipe.

Connection with coaxial pipes
fig. 25 - Examples of connection with coaxial pipes (
For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to fig. 33. Any horizontal sections of the fume exhaust must
be kept sloping slightly towards the boiler, to prevent possible condensate from flowing
back towards the outside and causing dripping.

Before carrying out installation, check with table 2 that the maximum permissible length
is not exceeded, taking into account that every coaxial bend gives rise to the reduction
indicated in the table. For example, a Ø 80/125 duct comprising a 90° bend + 1 horizontal
metre has a total equivalent length of 1.5 metres.

Separate Ø80 ducts can be connected directly to the unit.
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 4 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 3.

3.6 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 approx. 0.5 l. of water and connect the hose
to the disposal system.

ATTENTION: The unit must never be operated with the trap empty!
