ECONCEPT 51/51i - 101/101i
Accessing the electrical terminal block
The electrical terminal block is located inside a sealed box at the bottom left of the cab-
inet. Make the electrical connections as shown in the wiring diagram on sec. 47 and run
the cables through the special cable glands.

2.
Carry out all the electrical connections (terminals 4 to 24) 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. 27.
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 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 concerning the positioning of wall and/or roof terminals and minimum distances
from windows, walls, ventilation openings, etc.
Manifold, ducts and flue must be suitably sized, designed and made in compliance with
current regulations. These must be made of suitable materials, i.e. resistant to heat and
corrosion, smooth on the inside and hermetic. In particular, joints must be condensate
tight. Also provide for suitable condensate drain points, connected to a trap to prevent
the condensate formed in the flues from running into the generators.
B
The unit is equipped with two separate Ø80 flue connections for the two burner
- exchanger units (fig. 28) located inside the cabinet.
The combustion circuits of the two units are completely independent. When
joining the two fume outlets to a single flue or manifold (in case of a single mod-
ule or connection in cascade) it is necessary to install a fume anti-backflow
valve on each outlet to prevent operation anomalies or to creation of hazard-
ous conditions. Make sure to use the optional kits FERROLI, provided with spe-
cial anti-backflow valves for installing inside the cabinets, in a position protected
against the atmospheric agents.
Before carrying out the flue connection, make sure to fill the condensate tank
A
as indicated incap. 3.6.
