BOILER OPERATING INSTRUCTIONS
Make sure that the authorised technician who tested the boiler has stamped the guarantee booklet.
The installation, first start-up, regulation and maintenance operations must be carried out exclusively by qualified
personnel. Incorrect installation can cause damage to property and injury to persons or animals, for which the
manufacturer will not be held responsible.
During the installation, the technician must carry out the following checks:
■ The data on the data plate must correspond to that of the mains supply networks (gas, electricity, water);
■ The boiler must be regulated according to its designed use and performance;
■ The flue gas exhaust and combustion air intake system must be correctly installed and operational;
■ The exhaust gas discharge and ventilation systems must comply with the requirements of national and local
standards regardless of whether the boiler is installed indoors, outdoors or in its own cabinet (see section
“Reference standards”.
General warnings
 If there is any doubt as to whether the appliance has been tested by an authorised technician, do not attempt
to start it. All maintenance and gas conversion operations MUST BE CARRIED OUT BY PROFESSIONALLY
QUALIFIED PERSONNEL, registered in accordance with current legislation.
 Make sure that the requirements relating to the air intake and ventilation of the room in which the
boiler is to be installed have been complied with.
 The boiler is fitted with an antifreeze system. If the boiler is installed in a location where there is a risk of
freezing, the anti-freeze system will only come into operation if there is power supply to the boiler and the gas
supply valve is open. The manufacturer will not be held responsible for damage to the boiler caused by non-
compliance with this instruction.
 Should any part of the boiler freeze-up, do not attempt to light it under any circumstances, but instead call the
Service Centre immediately.
 The appliance’s combustion system must be checked every two years. This check includes testing the
efficiency of the boiler and must be carried out by authorised personnel possessing the qualifications as
required by current law.
 Do not obstruct the ventilation openings in rooms where there are gas-burning appliances installed (boiler,
cooker, etc.).

Starting - up the boiler
 Open the gas Isolation valve located under the boiler.
 Switch on the boiler by placing the ON/OFF switch
(1) in the ON position (see “Control panel”).
 The boiler will light automatically (with the WINTER
mode selected and room thermostat connected).
 Check that there are no flashing numbers on the
display 8 (see error codes). If code H2O appears on
the display 8 this denotes that there is no water in the
boiler. Consequently, fill the system as described in
section “Filling the system”.
■ “WINTER” mode
To switch boiler operation to “WINTER” mode, press
button 6 (see fig. 1). The boiler will only work for the
central heating system. The “WINTER” mode setting of the boiler is signalled by the symbol lit continuously on
the control panel.
The automatic ignition system will light the burner every time there is a demand for room heating. In this case, the
symbol on the control panel will flash.
■ Regulating the heating temperature
The heating temperature is regulated by knob 2 (see fig.1).
 Rotating the knob anticlockwise reduces the temperature.
 Rotating the knob clockwise increases the temperature.
 The range of temperature settings for the central heating runs from a minimum of 30°C to a maximum of 80°C,
or, in the case of low temperature operation, from a minimum of 25°C to a maximum of 59°C.

■ Topping-up the system with water
The water pressure in the central heating circuit must be
checked during the entire period of operation of the boiler.
In this respect, the reading on the pressure gauge M (fig.
2), located on the lower part of the boiler, must not be less
than 1 bar.
If there is insufficient water in the boiler, the code H2O will
flash on the display (see fig 2).
To bring the system back up to pressure, open the
external filling tap R (fig. 2) and use the pressure gauge M
(fig. 2) to check that the system pressure reaches 1 bar
and that the code H2O lights up.
When the operation is complete, close the fill tap.
Diagnostics – Error codes:
This paragraph contains a list of error codes that the boiler may generate on the display 8 (see “Control panel”)
together with the relative indications and the operations that the user can carry out to reset the boiler.
If the problem re-occurs after the following actions have been taken, call an authorised Service
Centre.
_E01_ Ionisation block
Code E01 lit continuously on the display.
 Check that the gas valve on the boiler and gas meter are open and that there is gas in the mains supply (or in
the tank).
 Switch off then switch on the appliance using switch 1 (see “Control panel”) on the control panel.
 When the error code on the display disappears, the boiler will restart.
If the problem persists, Call the Service Centre.
_E02_ Safety Thermostat tripped
Code E02 lit continuously on the display. Call the Service Centre.
_h2o_ Water Pressure Switch tripped
Code H2O lit continuously on the display.
 Check the water pressure in the central heating circuit. The reading on the pressure gauge M (see fig. 2),
located on the lower part of the boiler, must not be less than 1 bar .
 If the pressure is less than 1 bar, top-up the system as described in paragraph “Filling the system”.
 The boiler will restart automatically.
If the problem persists, Call the Service Centre.

system.
 Leave the boiler in standby, leaving the electricity and gas supplies connected and, consequently the anti-freeze
