Regular annual maintenance will maintain the proper functioning of the heating device, ensure its greater efficiency,
maintain the warranty and extend the life span of the device itself.
The procedures described in the previous section are advisable at the end of the heating season. The purpose is to check
and ensure the perfect operation of all components.
CHARACTERISTIC BUILT-IN ELEMENTS
THE BOILER IS A COMPLETE PRODUCT AND IT HAS ALL NECESSARY HEATING SYSTEM ELEMENTS BUILT IN, AND THESE
INCLUDE:
CIRCULATION PUMP
It is installed on the return pipe of the boiler , on the boiler itself.
The circulation pump is RS30 / 6.
Another pump is not required except for special heating (floor, with accumulating boiler, etc.).
The pump is reached by removing the so-called the inspection cover which, when you are facing the boiler , is attached
to the sheet metal on the left side of the boiler with screws (Figure 17). Therefore, there must be a greater distance between the
left side of the boiler and the wall. The diagram proposes 700mm.
The circulation pump (Figure 18) has the ability to operate at 2 or 3 speeds, depending on the resistance in the heating
system. The second speed is factory set. If necessary, you can change the speed.
If a high efficiency pump (for the needs of the EU) is installed, it adjusts the speed itself depending on the resistance in
the system.
The electronic parameters are set to activate the pump at water temperature of 50 ° C, and switches off at 47 ° C.
The pump shaft must be in a horizontal position. Therefore, be careful when connecting to a heating installation so that
it does not rotate.
When the pump does not operate for a long period of time, there is a risk that the pump shaft jams and cannot start at
the set water temperature (50 °C.). In this case, reach the pump and use the screwdriver to remove the short screw from
the pump head (a little water will flow), and then use the screwdriver to get the pump shaft located under the removed
screw working by turning the pump shaft with the screwdriver left-to-right.

EXPANSION TANK
By removing the inspection cover (Figure 17), you can reach the expansion tank (Figure 19).
The volume of the expansion tank is 18 litres.
The factory set pressure is 1 bar.
It has function to stabilize the pressure in the heating installation.
It meets the boiler heat capacity of 37.5KW and another tank is not required up to this heat power. It can be used, but it
does not have to.
For larger systems, larger expansion tanks are needed for larger water volumes.
The expansion tank has a pressure regulating valve in it.
FILL AND DRAIN COCK
By removing the inspection cover (Figure 17), the fill and drain cock is reached (Figure 20).
As the name says, it serves to fill and drain the installation.
It is located at the lowest point of the system.
The inlet connector is R1 / 2 "and the outlet connector has hose extension. It is ball shaped.
ELECTRONIC SYSTEM
By simply removing the inspection cover (Figure 17), you can reach the electronic system (Figure 21).
The electronic system is "TIEME" from Italy.
The electrical connection diagram is given in this Manual.
All cables, from all consumers, from safety mechanical thermostats, electronic probes, pressure switches, etc. are
connected to the electronic system.
