8.5
Connecting pipe of the safety valve
Caution!
Danger of hot water burns!
The connecting pipe of the pressing of the safety valve is connected to the drain pipe to the sewage system.
Otherwise, there is always the risk of flooding, for which the manufacturer of the central heating station is not responsible.
8.6
Air/ burnt gases input/ output pipes
The smoke vent is an important part of the functioning of the central heating gas boiler; and it needs to comply with the
following requirements:
- it must be made of water-proof material, resistent to the temperature of the gases and to condensation;
- it must have sufficicent metallic durability and reduced thermal conductibility;
- it must be completely air-tight so as to avoid dropping of temperature caused passive flow of air;
Recommended distances are presented in chapter 11.1.
Caution!
It is obligatory to place central heating stations in rooms with proper ventilation systems according to applicable
norms.
This boiler with natural flue is designed to be connected exclusively to an exhaust pipe common to more houses in
the existing builidings, by which the burning exhaust are evacuated towards the exterior of the building housing the
boiler. This draws the burning air directly from the room and has a flue clack valve. Because of lower efficiency, any other use
of this boiler must be avoided, otherwise it may result in higher energy consumption and bigger operational costs.
Danger!
It is completely forbidden to use the central heating station without the burnt gases output pipes because it
endangeres people’s life and health of people.
Installation is to be performed only by authorized personnel following applicable laws.
8.7
Electric grid connection
The central heating station must be connected to one-phase network of 230V - 50Hz with protection null.
Dispersion withstand of the earthing switch (earthing) must comply with applicable norms (maximum 4 ohm, and the working
null must not have residual current).
Electric powering of the central heating station will be executed from a separate circuit provided with differential protection
fuses of 30 mA.
External connections must comply with applicable norms. Connection to the electric grid of the building must allow the entire
electric insulataion of the central heating station for situations when interventions are required.
Grid connection is done taking into account the symbolism of colours as follows:
Brown
= phase,
Blue
= null,
Green and Yellow
=
earthing.
The current plug must be accessible so that the user can easily disconnect it.
Caution!
It is not allowed to mount the central heating station with a defective electric installation or with no earthing.
Danger of death by electric shock with electric contacts!
8.8
Installation filling and emptying
The following operations are executed to fill the installation:
- ellectrically power the central heating station;
- open the filling tap (fig. 1.4) of the central heating station
and of the thermal/ house water installation;
- load the boiler with a pressure of about 0.4 bar, indicated on
the display;
- open the pump air vent;
- activate the boiler ventilation module to vent the system:
press the J7(
) key for activation and the pump will start,
the boiler is in the OFF (Stand-by) state, to deactivate it press
the J7(
) or by turning on the POWER button;
- Adjust the pump operation (5, 6 or 7m) depending on the
installation (see chapters 8.3 and 11);
- continue to fill the system, with the ventilation function
switched on up to
1.1-1.5 bar
;
*figure contains ERP pump
- check the tightness of the entire system. If there are losses, the problems must be remedied;
In the case of plants equipped with automatic ventilation: keep the pump on until noises are heard in the installation;
In the case of plants without automatic ventilators: manually operate the manual air vent to remove the air from the main
exchanger until noises are heard in the installation;
- heat the radiators;
- Make 2-3 cycles of 50-60 seconds of air-venting, following the steps described above;
- check the system pressure indicated on the display. If necessary, fill with thermal agent following the above steps.
- Remove the flexible hose.
If necessary, fill with thermal agent following the above steps.
