USE OF THE BOILER
To ensure that your system operates correctly, please
have it serviced annually by a qualified engineer;
servicing should be completed before the start of the
heating season.
Starting the burner:
in normal operation the burner starts automatically if
the temperature of the boiler is below the set point.
Before carrying out any work on the boiler, isolate it
from the electrical supply at the switch on the external
control box.
Also move the main switch on the control panel to
“OFF”.
• You should familiarise yourself with the control panel
(fig. 1)
The user must not attempt to gain access to the
components inside the control panel.
1. Main switch
Use this switch to turn the boiler on and off.
2. Summer/Winter switch
Use this switch to start and stop the heating pump.
3. Energy selection switch
This is used to switch the heating pump and the burner off (or on).
It is used to switch a 2.4 kW resistor on (or off) for the provision of
hot water.
4. Indicator lamp of the heating element
This lamp indicates that the heating element is energised.
5. Time clock
This allows the boiler to be limited ON and OFF operates on a 24
hour sequence. Around the outside of the clock there are a number
of white tabs, these allow 15 minute switching periods. To set the
time clock simply push outwards the number of tabs required for
ON period.
Remember : TAB IN = BNE OFF
TAB OUT = BNE ON
6. Hot water temperature control thermostat
In hot water mode, the temperature of the hot water can be adjusted
from 60 to 80°C.
7. Thermostat-pressure gauge
This gauge shows the temperature of the boiler and the pressure in
the primary heating circuit. The temperature must not exceed 90°C.
If it rises above this point, turn off the boiler and check the settings
on the thermostat. If the problem persists, call a technician.
The pressure must not fall below 1 bar. If it does fall below this point,
look up the section entitled “Gauge pressure of the heating installation”
in this section below.
8. Heating temperature control thermostat
n “Winter” position the boiler temperature can be set to between 60
and 90°C.
It is advisable to set this thermostat 10°C above the hot water
thermostat setting.
Pump operation:
The pump is controlled by a reset high limit thermostat, which is
located at the rear of the boiler. This is pre-set at 45°C. When the
boiler starts up, it delays the activation of the boiler pump, there by
preventing any risk of corrosion in the combustion chamber.
Gauge pressure of the heating system
Your system must be fitted with a heating safety valve calibrated to
3 bars.
Ensure that the system is always under water pressure. When the
system is cold and the air inside it has been vented, the gauge
must indicate a pressure between 0.5 and 1.5 bar depending on the
height of the building.
To add water: (fig. 9 page 9)
• Open the filling valve (5).
• Close the valve properly after filling.
• Vent the system in order to obtain an accurate reading of the
pressure inside the heating circuit.
Safety valves (heating circuit) (fig. 9 page 9 - item 2)
If water is found to be escaping from one of the safety valves, stop
the boiler and contact your installer for advice.
A monthly test is recommended:
Lift the lever on the drain cock for a few seconds to ensure that the
safety valve is working correctly.
If there is a problem after this short test, please
contact your installer for advice.

EN • 5
664Y1200.B
ENGLISHFRANCAISNEDERLANDSESPAÑOL
The water escaping from the safety valve can
be extremely hot and cause serious burns.
Safety group (hot water circuit)
It is normal for water to escape from the safety group each time the
hot water tank is heated. A hot water expansion vessel may reduce
or even prevent this escape. (fig. 10 page 9 - item. 6)
A monthly test is recommended:
Lift the lever on the drain cock for a few seconds to ensure that the
safety valve is working correctly.
If there is a problem after this short test, please
contact your installer for advice.
The water escaping from the safety group can
be extremely hot and cause serious burns.
BURNER SHUTDOWN
If the burner is not working:
1. The burner indicator lamp lights up.
2. Press the burner reset button (fig. 2) on the burner. Turn the boiler
off for several seconds at the main switch, then restart the boiler.
fig. 2
3. If the burner still does not work, remove the boiler front panel
and reset the high limit thermostat on the top of the boiler body
(fig. 3).

INSTALLATION
ELECTRICAL CONNECTIONS
Power supply principle
The boiler operates on a single-phase supply of 230 V/50 Hz.
You should install a control box with main switch and 6A fuses
externally to the boiler to allow the boiler to be isolated from the
supply for servicing and repairs.
Statutory compliance
The installation must comply with your local standards and codes
of practice.
Safety
The stainless steel if present water tank must be provided with a
separate earth.
The boiler must be isolated from the electrical supply
before any work is carried out on it.
The heating element consists of two 2.4 kW electrical
resistors.
One of these two resistors is wired and used as the main
resistor. The other resistor is not used, and serves only
as a back-up if the first resistor becomes faulty.
The two resistors must never be connected to operate
together, as this will damage the internal wiring of the
boiler.
