Condensate collection
The discharge manifold (Fig. 5) collects condensate water, any evac-
uation water from the safety valve and the system discharge water.
The manifold must be connected via a rubber pipe (not provid-
ed) to an appropriate collection and evacuation system in the
white water discharge drain in compliance with current regula-
tions. The outer diameter of the manifold is 20 mm: it is there-
fore 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 result-
ing from the failure to channel the condensate.
Sealing of the condensate drainage connection line must be
guaranteed.
3.9
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)
- 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 suita-
bly 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 low-
er 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 and UNI
11071. 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 accesso-
ries 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 provid-
ed 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 UNI 11071, the boiler is designed to take
in and dispose of flue gas condensate and/or meteoric water conden-
sate 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.
if a condensate relaunch pump is installed, check the technical
data (provided by the manufacturer) regarding output, to en-
sure it operates correctly.
POSSIBLE OUTLET CONFIGURATIONS (fig. 11)
B23P-B53P - Suction in room, with external outlet.
C13-C13x - Concentric wall outlet. Pipes can leave the boiler inde-
pendently, but the outputs must be concentric or near enough in or-
der to be subjected to similar wind conditions (within 50 cm)
C33-C33x - Concentric roof outlet. Output as C13.
C43-C43x - Discharge and suction in common, separate smoke
pipes, but subjected to similar wind conditions.
C53-C53x - Separate wall or roof outlet and suction line and in areas
with different pressures. Outlet and suction line must never be placed
on opposite walls.
C63-C63x - Outlet and suction line carried out with pipes marketed
and certified separately (1856/1).
C83-C83x - Outlet in single or regular smoke pipe and wall suction
line.
C93-C93x - Discharge on the roof (similar to C33) and air suction
from a single existing smoke pipe.
See the prevailing standards.
"FORCED OPEN" INSTALLATION (TYPE B23P/B53P)
Flue gas discharge pipe ø 80 mm (fig. 12)
The flue gas outlet pipe can be directed to the most suitable direction
according to installation requirements. For installation, follow the in-
structions supplied with the kit.
In this configuration, the boiler is connected to the flue gas outlet pipe
of ø 80 mm through an adaptor of ø 60-80 mm.
In this case, the combustion air is picked up from the boiler
installation room (which must be a suitable technical room with
proper ventilation).
The non insulated flue gas outlet pipes are potential sources of
danger.
Arrange the flue gas discharge pipe so it slopes by 3° towards
the boiler.
