Put the WiFi Box onto the hood of the boiler using the magnet on
the back.
- Position the WiFi Box in a place where the WiFi signal is not weak
(recommended above 30%).
- Power up the WiFi Box using the relative cable and power supply
provided as standard.

Condensate collection
The discharge manifold (Fig. 5-5a) collects condensate water, any
evacuation water from the safety valve and the system discharge
water.
The manifold must be connected via a rubber pipe (not
provided) to an appropriate collection and evacuation system
in the white water discharge drain in compliance with current
regulations. The outer diameter of the manifold is 20 mm: it is
therefore advisable to use a rubber pipe Ø 18-19 mm closed
with a suitable clamp (not provided).
The manufacturer is not liable for any damage/flooding resulting
from the failure to channel the condensate.
Sealing of the condensate drainage connection line must be
guaranteed.

Electrical wiring
To access the electrical wirings, proceed as follows:
To access the terminal board:
- set the system's main switch to off
- undo the fixing screws (D) of the shell (fig. 6-6a)
USB
TA = Black
OT = Red
- move the shell base forward and then upwards to unhook it from
the chassis
- lift and then turn the instrument panel upside down (fig. 7)
- remove the electrical parts inspection cover (fig. 8)
The connection to the mains supply must be made via a separation
device with an omnipolar opening of at least 3.5 mm (EN 60335/1,
category 3).
The appliance operates with an alternating current of 230 Volt/50 Hz
and complies with the standard EN 60335-1.
It is obligatory to make the connection with a safe ground/earth,
in compliance with current directives.
The installer is responsible for ensuring the appliance is
suitably earthed; the manufacturer will not be liable for any
damage resulting from an incorrect or absent earth connection
It is also advisable to respect the phase-neutral connection
(L-N).
The ground/earth wire must be a couple of cm longer than the
others.
The boiler can operate with a phase-neutral or phase-phase supply.
For power supplies that are not earthed, it is necessary to use an
isolating transformer with earth-anchored secondary.
It is forbidden to use gas and/or water pipes to earth electrical appliances.
Use the power cable supplied to connect the boiler to the mains power
supply.
If the power cable needs to be replaced, use a cable of the HAR
H05V2V2-F type, 3 x 0.75 mm², with a maximum external diameter of 7
mm (fig. 9).
3.10
Gas connection
Before connecting the appliance to the gas network, check that:
- current prevailing standards have been met
- the gas type is appropriate for the appliance
- the piping is clean.
The gas pipe must be installed outdoors. If the pipe has to pass
through the wall, it must pass through the central opening in the
lower part of the template.
It is advisable to install a filter of suitable dimensions on the gas line
if the distribution network contains solid particles.
Once the appliance has been installed, check the connections are
sealed according to current installation regulations.
3.11
Flue gas exhaustion and air aspiration (fig. 10)
For flue gas discharge, refer to Standards UNI 7129-7131. Always
comply with local standards of the Fire Department, the Gas
Company and with possible municipal dispositions.
The discharge of flue gas is guaranteed by the centrifugal fan located
inside the combustion chamber. The boiler is supplied without the flue
gas outlet/air suction kit, since it is possible to use the accessories for
appliance with a forced draught sealed chamber that better adapts to
the installation characteristics.
It is essential for evacuating fumes and restoring boiler combustion
air that only original Riello pipes be used and that the connection is
made correctly as shown in the instructions provided with the flue
gas accessories.
A single smoke pipe can be connected to several appliances provided
that every appliance is the condensing type
The boiler is a C-type appliance (with airtight chamber), and must
therefore have a safe connection to the flue gas discharge pipe and
to the combustion air suction pipe; these both carry their contents
outside, and are essential for the operation of the appliance.
Both concentric and twin terminals are available.
As envisaged by standard regulations, the boiler is designed to
take in and dispose of flue gas condensate and/or meteoric water
condensate deriving from the flue gas discharge system. It does this
via its own drain-tap, if an external drain-tap is not fitted during the
design or installation phase.
The maximum lengths of the ducts refer to flue systems available
in the catalogue.
If a condensate relaunch pump is installed, check the technical
data (provided by the manufacturer) regarding output, to
ensure it operates correctly.
