System water characteristics
In case of water with hardness exceeding 25° Fr (1°F = 10ppm CaCO3), use suitably
treated water to prevent possible encrustations in the boiler. Treatment must not
reduce the hardness to values below 15°F (Decree 236/88 on water intended for
human consumption). However, treatment of the water is essential in case of very
large systems or frequent system water replenishment.
Frost protection system, antifreeze liquids, additives and inhibitors
A frost protection system activates the boiler in heating mode when the system
flow temperature drops below 6°C. The device is not active if the power and/or
gas supply to the unit are disconnected. If necessary, the use of antifreeze liquids,
additives and inhibitors is allowed, only and exclusively if their manufacturer
provides a guarantee ensuring that the products are suitable for use and do not
cause damage to the boiler exchanger or to other components and/or materials of
the boiler and system. The use of antifreeze liquids, additives and generic inhibitors,
not specifically suitable for use in heating systems compatible with the boiler and
system materials, is prohibited.

“Hi” - History Menu
The microprocessor is able to store the total hours with card powered (Ht), the last
10 faults (with details of time they occurred relevant to parameter Ht) and burner
operation hours (Hb).
The History datum item H1 represents the most recent fault that occurred, whereas
the History datum item H10 represents the least recent. The codes of the faults
saved are also displayed in the corresponding menu of the Opentherm remote
control.
Note for calculation of hours:
• Every 24 hours, the number shown in the part of the display normally reserved
for system pressure is increased by one unit.
• Every hour, the number shown in the part of the display normally reserved for
room temperature is increased by one unit.
Press the Heating buttons to scroll the list of faults.
Ht Total hours with card fed.
H1 Fault code --> Time fault occurred (relevant to Ht)
H2 Fault code --> Time fault occurred (relevant to Ht)

4.2 Commissioning
Checks to be made at first lighting, and after all maintenance operations
involving disconnection from the systems or an operation on safety de-
vices or partsof the boiler:
Before lighting the boiler
• Open any on-off valves between the boiler and the systems.
• Check the tightness of the fuel system.
• Check the pre-filling of the expansion tank
• Fill the water system and make sure that all air contained in the boiler and the
system has been vented by opening the air vent valve on the boiler and any vent
valveson the system.
• Make sure there are no water leaks in the system, hot water circuits, connec-
tions orboiler.
• Make sure the electrical system is properly connected and the earth system
worksproperly.
• Make sure there are no flammable liquids or materials in the immediate vicinity
ofthe boiler.
• Fit the pressure gauge and the vacuum gauge on the pump (remove after start-
ing)of the burner.
• open the gate valves along the diesel pipe
Start-up
fig.30 - Starting
A
When the thermostatic line closes, the burner motor starts turning together with
thepump: all the oil sucked is sent to the return. The burner blower and the ignition
transformer are also working, therefore the following stages are carried out:
• firebox preventilation.
• prewash of a part of the oil circuit.
• preignition, with discharge between electrode tips.
B
At the end of prewash, the unit opens the electromagnetic valve: the oil reaches the
nozzle, where it is finely sprayed.
Its contact with the discharge between the electrode tips creates the flame.
The safety time begins simultaneously.
