Connect the boiler to a 230V ~50 Hz mains supply.
VERY IMPORTANT: before turning the boiler on
make sure that the installation has been filled.
Domestic hot water
Turn on the cold water stopcock beneath the boiler.
Fill the unit by turning on the various hot water taps
in the installation.
Make sure that the assembly is completely airtight
and watertight.
The installation of a scale reducer/water softener is
recommended in hard water areas
To increase the hot water temperature, reduce the
flow of water at the hot water tap. This may be necessary in winter months.
Central heating system
The correct installation is to be carried out as follows:
Open the radiator air vents.
With the stopcock on and domestic cold water
going through to the boiler, fill the central heating system by opening the filling tap provided by your
installer.
Close the air vents off once water starts coming out
of each of them.
Close the filling tap when the pressure gauge
exceeds the pressure of 1.3 bar. Max = 1.5 bar.
By turning the main control switch to the winter setting . When the pump works the pressure in the digital display increases.
Vent the central heating system once more. Then
let the pressure in the system settle at 1.3 bar. Max =
1.5 bar..
Make sure that there are no leaks in the installation.
Make sure that the heating system is completely
full and vented. The pressure gauge should show
between 1.3 and 1.5 bar with cold water in the heating system.
Make sure that the boiler is wired to the correct volt-
age.
Make sure that the combustion flue outlet is not
restricted.
Gas circuit
Turn on the gas stopcock to the installation.
Check that the whole gas circuit and gas connec-
tions to the boiler are airtight.
Settings
Before leaving the factory the boiler is pre-set in
accordance with the information on the adhesive data
plate, and therefore needs no further adjustment.
Should the type of gas need to be changed, check
with the corresponding section.

Domestic hot water service.
Turn the main control switch in the summer setting in
order to turn the boiler on , see the figure below
(the green light turns on). At that moment the boiler
will be ready to supply domestic hot water whenever
there is a demand for it.
When you turn on any of the hot taps the boiler will
automatically come on with the pilot light switching on
first of all followed by the burner. A water temperature
of between 35° and 60° C can be selected by turning
the domestic hot water temperature regulating knob.
When the D.H.W. temperature regulating knob is
turned the digital display will show the values of the
temperature.
Hot water and central heating service.
Turn the switch to the winter setting . The burner
will automatically fire up if the clock and/or the roomthermostat are calling for heat. A temperature of
between 60° and 85° C can be selected by turning
the heating temperature regulating knob. This will
stay on until it achieves the temperature selected
either in the room thermostat or in the boiler itself.
Whenever domestic hot water is required when it is at
the central heating setting, the boiler is designed to
give priority to the supply of domestic hot water, with
the central heating on hold, until the demand for
domestic hot water ceases. When the D.H.W. temperature regulating knob is turned the digital display
will show the values of the temperature.
Switching off the boiler.
Turn the main switch to the setting O.
Reset of the boiler.
This unit has a built-in reset indicator. Whenever
any fault is detected in the ignition process, the boiler goes to lock out and the reset indicator switches
on and the fault code is shown in the display.
To reset the boiler turn the main switch to position
O. The reset indicator should then turn off.
When the system pressure either falls down to 0.6
bar or goes over 2.8 bar, the display will shown F-3.
It needs to fill it up to 1.3-1.5 bar (when system cold).
IMPORTANT: If the boiler has not been used for a
length of time, or a new gas bottle is connected, the
unit could lock out due to the presence of air in the
pipes. Should this happen, the ignition procedure
should be repeated until the gas circuit is cleared of
all air in the gas supply.
USER
Check the gas connections and make sure that the gas is coming into the boiler (that the gas tap is open)
Make sure that the heating system is completely full and vented. The pressure gauge should show between
1.3 and 1.5 bar with cold water in the heating system.
Make sure that the electricity supply to the boiler is switched on.

6.- FAULT CODES
Should a fault develop within the boiler
(diagnostic), the P.C.B. will diagnose the
possible cause via the reset indicator light
(Red Neon) and the digital display. The
fault will be shown in the display.
Each fault code begins with an “F” followed by a number. Ranging from 1 - 13.
To reset the fault use the reset switch (4)
(see Control Panel page 4)
The boiler has an frost protection security system.
IMPORTANT: the boiler must be electrically
supplied and gas connected for this to operate.
Frost protection
When the heating thermistor detects a temperature of
6ºC, only the pump will switch and will continue to run
until a temperature of 9ºC is obtained.
If the temperature drops to 3ºC, the boiler will start on
minimum power until the temperature of 20ºC is
obtained.
NOTE: If the boiler is not to be used for a long period drain the heating installation using the valve (Z)
beneath the boiler and the D.H.W. installation.
The D.H.W circuit must be drained down as follows:
Turn off the cold water supply.
Open all the hot water outlet taps in the installation
(at least one tap should be found at a level lower than
the boiler).
Release the tap to drain the flow switch to allow air
to come in and for the stored water in the boiler to be
able to leave.(see figure)
When the operation is finished, close the hot water
outlet taps and the draining tap.
To put the boiler back into service, open the cold
water inlet tap.
When the boiler is not being used, the pump will automatically run for one minute every 24 hours to prevent seizure. TO ENSURE OPERATION OF THIS
DEVICE ELECTRICAL SUPPLIES MUST BE ON.
If the pump jammed when the appliance is turned
back on, consult your installer or service engineer.
