4 INSTALLATION
Ensure that the mains voltage available coincides with that shown on the rating label.
The electrical installation must comply with the current regulations. The cross-section of the power
conductors must be sufficient for the rated power or the power to which the boiler has been limited.
Install the necessary electrical protections as indicated in the current regulations. In the event of these
regulations not being complied with, the manufacturer will not be liable for any bodily injury or material
damage that may occur.
It is necessary to install the boiler in such a manner that it can be separated from all the poles of the
electricity mains with a contact clearance width of a minimum of 3 mm.
The hydraulic connections to the heating and S.H.W. circuit must be carried out respecting the out and
return marked on the boiler.
Install purges in the radiators and high points of the installation.
Install the discharge valve at the lowest point of the installation, in order to be able to empty the
installation completely if necessary.
We recommend running the heating circuit pressure safety valve to the drain in order to avoid a water
spillage in the event of the pressure exceeding 3 kg/cm
It is essential to run the safety pressure valve of the S.H.W. header rated at 7 kg/cm
If the circuit pressure exceeds 5 kg/cm
at the exit from the water meter of the dwelling.
It is essential to connect the boiler to a good earth connection.
The boiler can be controlled by an external regulator, for example an ambient thermostat or an ambient
chrono-thermostat. This must be connected to the terminals on the electronic board once the existing
bridge between both terminals has been suppressed. (See the electrical diagram). The use of an external
regulator is essential for the modulating system to work.
The installation must be performed in such a manner as to facilitate maintenance and repair work. The
hydraulic connections must be made using flexible couplings or hoses in order to facilitate disconnecting
the boiler from the circuit. If these aspects of the installation are not adhered to, the Technical Service will
not be obliged to repair the boiler.
Before carrying out any work inside the boiler, do not forget to disconnect the electrical supply.
This boiler is not designed to be installed in the open air.
If the heating installation includes hydraulic thermostatic valves or automatic area controls, it is necessary
to avoid at all times interrupting the water circulation, as this will activate the safety thermostat.
5 COMMISSIONING
5.1 HEATING
Check that the drainage points located in the lower part of the installation are completely closed.
Open the purges of the installation and the boiler.
Open the filling valve until the water pressure gauge reads between approximately 1 and 1.5 bar.
Close the installation purges when water begins to flow through them. The boiler purge must not be closed.
Start the heating by pushing the
Select a set point higher than the temperature indicated on the heating display and check the consumption once the
operating indicator of the central heating resistances lights up. The S.H.W. has priority; if the S.H.W. is connected
and consuming, this point cannot be verified.
Purge the installation again if necessary.
Reinstate any possible losses in pressure by opening the filling valve until the pressure gauge reads between 1 and
1.5 bar.
If the boiler includes the option of radiant floor heating (requested on placing the order), the central heating safety
thermostat will activate at 80°C and the temperature of the heating resistance cannot exceed 50°C.
