QUADRIFOGLIO
For the connection in cascade
Note: The boiler's electronics can manage up to 6 modules.
1. Connect the modules as shown in fig. 33 (example with 4 modules)

2. Carry out all the electrical connections (terminals 4 to 27) on module no. 1
3. On the remaining modules, only connect the power supply and possible contacts
for: burner lit (300), fault contact (301) and remote reset input (302).
4. Switch on the power to the entire cascade
5. After the "FH" procedure, check 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. 33.
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.

3.6 Flue connection

Important
The unit is a B23 type with combustion air drawn from the installation room and fume ex-
haust by means of a fan (operation with flue pressurised), and must be connected to one
of the discharge systems indicated below. Before proceeding with installation, check and
carefully comply with the local regulations and provisions. Also, comply with the provi-
sions on the positioning of wall and/or roof terminals and the minimum distances from
windows, walls, ventilation openings, etc.
Manifold, ducts and flue must be suitably sized, designed and made in compliance with
current regulations. They must be made of suitable materials, i.e. resistant to heat and
corrosion, smooth on the inside and tight. In particular, joints must be condensate proof.
Also, provide for adequate condensate drainage points, connected to a trap to prevent
the condensate formed in the flues from running inside the generators.
B
Each unit is provided with two flue connections to offer greater installation flexibility. Use
only one of the outlets and check that the other one is correctly plugged (see fig. 34).
When installing in a bank with fume outlets connected to a single flue or manifold a fume
anti-backflow valve must be installed on each outlet to prevent operation faults or
the onset of dangerous conditions. Make sure to use the optional kits FERROLI, provid-
ed with special anti-backflow valves.

Before carrying out the flue connection, make sure to fill the condensate trap
A
with approx. 0.5 litres of water through the flue connections.
To calculate the maximum length of the flues, refer to the max. available head indicated
in table 2.

3.7 Condensate drain connection

The boiler is equipped with a trap to drain condensate Carry out the following instructions for fitting.
fig. 35 - Condensate outlet connection
Neutralizer kit
The following condensate neutralizer kits are available on request:
code 051000X0 up to 320 kW (per single device)
code 051000X0 up to 1500 kW (per bank)
Connect these neutralizers directly to the boiler outlet without putting the trap in be-
tween. The trap function is carried out by the neutralizer.
4. SERVICE AND MAINTENANCE
All adjustment, conversion, commissioning and maintenance operations described be-
low must only be carried out by Qualified Personnel (meeting the professional technical
requirements prescribed by the current regulations) such as those of the Local After-
Sales Technical Service.
FERROLI declines any liability for damage and/or injury caused by unqualified and un-
authorised persons tampering with the unit.
4.1 Adjustments
Gas conversion
The unit can operate on Natural Gas or LPG and is factory-set for use with one of these
two gases, as clearly shown on the packing and on the dataplate. Whenever a different
gas to that for which the unit is set has to be used, the special conversion kit will be re-
quired, proceeding as follows:
1. Disconnect the power supply to the boiler.
2. Remove the panels.
3. Detach the electrical connections from the gas valve controller.
4. Unscrew the knob "A" fastening the gas valve (see fig. 36, fig. 37 and fig. 38 for the
various models).
5. Undo the fixing screws "E" and remove the gas valve.
6. Replace the gas valve "F" positioning it inside the gasket "G" with that contained
in the conversion kit. Refit the parts and check the tightness.
7. Modify the parameter for the type of gas:
• put the boiler in standby mode
• press the DHW buttons simultaneously (part 1 and 2 - fig. 1) for 10 seconds.
the display shows "P01" flashing.
• press the DHW buttons simultaneously (part 1 and 2 - fig. 1) to set parameter
00 (for operation with natural gas) or 01 (for operation with LPG).
• press the DHW buttons simultaneously (part 1 and 2 - fig. 1) for 10 seconds.
The boiler will return to standby mode
8. Apply the label, contained in the conversion kit, near the dataplate.
9. Using a combustion analyzer connected to the boiler fume outlet, make sure the
CO content in the fumes, with the boiler operating at max. and min. output, com-

plies with that given in the technical data table for the corresponding type of gas.
