Condensate collection
The discharge manifold (Fig. 5) collects condensate water, any
evacuation water from the safety valve and the system discharge
water.
b
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).
b
The manufacturer is not liable for any damage/flooding resulting
from the failure to channel the condensate.
b
S ealing of the condensate drainage connection line must be
guaranteed.
3.8
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.
b
It is obligatory to make the connection with a safe ground/earth,
in compliance with current directives.
b
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
b
It is also advisable to respect the phase-neutral connection (L-N).
b
T he 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.
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).
3.9
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.
3.10
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.
b
The maximum lengths of the ducts refer to flue systems
available in the catalogue.
b
If a condensate relaunch pump is installed, check the technical
data (provided by the manufacturer) regarding output, to ensure
it operates correctly.
b
The straight length measurement is inclusive of the first bend
(boiler connection), terminals and joints; with the exception of
the vertical coaxial duct Ø 60-100 mm, where the straight length
does not include the bends.
POSSIBLE OUTLET CONFIGURATIONS (fig. 11)
B23P-B53P - Suction in room, with external outlet.
C13-C13x - Concentric wall outlet. Pipes can leave the boiler
independently, but the outputs must be concentric or near enough in
order 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.
b
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
instructions 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.
b
In this case, the combustion air is picked up from the boiler
installation room (which must be a suitable technical room with
proper ventilation).
b
The non insulated flue gas outlet pipes are potential sources of
danger.
