Press the heating buttons
onds to activate the mode. The boiler lights at the maximum heating power set as
described in the following section.
The heating symbol (detail 13 - fig. 1) and DHW symbol (detail 9 - fig. 1) flash on the
display; the heating power will be displayed alongside.
To deactivate the TEST mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes.
In TEST mode, press the button (detail 7 - fig. 1) to obtain the following operation:
• Top boiler shell on; bottom boiler shell off.
• Top boiler shell off; bottom boiler shell on.
• Top boiler shell on; bottom boiler shell on.
To adjust the heating power, switch the boiler to TEST mode (see sec. 4.1).
Press the (details 3 and 4 - fig. 1) to increase or decrease the power
(min. = 00 - max. = 100).
Press the (detail 8 - fig. 1) within 5 seconds; the max. power will remain
that just set. Exit the TEST mode (see sec. 4.1).

Checks to be made at first lighting, and after all maintenance operations that involved
disconnection from the systems or an operation on safety devices or parts of the boiler:
• Open any on-off valves between the boiler and the systems.
• Check the tightness of the gas system, proceeding with caution and using a soap and water
solution to detect any leaks in connections.
• Check correct prefilling of the expansion tank (ref. sec. 5.4).
• Fill the water system and make sure all air contained in the boiler and the system has been
vented, by opening the air vent valve on the boiler and any vent valves on the system.
• Fill the condensate trap and check correct connection of the condensate elimination system.
• Make sure there are no water leaks in the system, DHW circuits, connections or boiler.
• Check correct connection of the electrical system and efficiency of the earthing system
• Make sure the gas pressure value for heating is that required.
• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler
• Turn the unit on as described in sec. 2.3.
• Make sure the fuel circuit and water systems are tight.
• Check the efficiency of the flue and air-fume ducts while the boiler is working.
• Check the correct tightness and functionality of the condensate elimination system and trap.
• Make sure the water is circulating properly between the boiler and the systems.
• Make sure the gas valve modulates correctly in the heating and domestic hot water produc-
tion phases.
and
• Check proper boiler lighting by doing several tests, turning it on and off with the room thermo-
stat or remote control.
• Using a combustion analyser connected to the boiler fume outlet, check that the CO
in the fumes, with the boiler operating at max. and min. output, corresponds to that given in
the technical data table for the corresponding type of gas.
• Make sure the fuel consumption indicated on the meter matches that given in the technical
data table on sec. 5.4.
• Check the correct programming of the parameters and carry out any necessary customization
(compensation curve, power, temperatures, etc.).
To keep the unit working properly over time, it is necessary to have qualified personnel make an
annual check that includes the following tests:
• The control and safety devices (gas valve, flow meter, thermostats, etc.) must function cor-
rectly.
• The fume extraction circuit must be fully efficient.
• The airtight chamber must be sealed
• The air-fume end piece and ducts must be free of obstructions and leaks
• The condensate evacuation system must be efficient with no leakage or obstructions.
• The burner and exchanger must be clean and free of scale. When cleaning, do not use chem-
ical products or wire brushes.
• The electrode must be free of scale and properly positioned.
• The gas and water systems must be airtight.
• The water pressure in the cold water system must be about 1 bar; otherwise, bring it to that
value.
