usE of thE BoilEr
Please get your system serviced every year by a qualified
technician. More frequent servicing may be required depending
on boiler use. If this is the case, consult your installer for
advice.
Starting the burner:
In normal operation, the burner starts automatically as soon as
the boiler drops below the temperature setpoint.
Before the boiler is serviced, switch off the electrical supply
with the external isolator.
Also switch the general switch on the control panel to “OFF”.
hEatinG circuit prEssurE
The heating circuit pressure must be at least 1 bar and must be regularly
checked by the end user. Always make sure that the appliance is off when
refilling the system. To do this, use the ON/OFF switch. For further information,
please contact your installer.
A safety valve is provided under the appliance. If the pressure of the installation
exceeds 3 bars, this valve opens and water from the system is drained off. If this
happens, please contact your installer.
water from the safety valve may be extremely hot
and cause very severe burns.
GEttinG to KnoW thE control panEl
1 - Control thermostat
If the boiler is only used for producing hot water, the boiler temperature may
be adjusted between 60 °C and 90 °C.
If the boiler is used for hot water and heating, the boiler’s control thermostat
will generally be set to 80 °C for optimum operating conditions.
2 - General switch
This switch is used for starting and shutting down the boiler.
3 - Summer/winter selector
This is used to turn the heating circulator on and off (if connected directly to
boiler wiring).
4 - Temperature-pressure gauge
This gauge displays the boiler temperature and the pressure inside the primary
circuit. The temperature should not exceed 90 °C. If it is higher than this,
the boiler should be shut down and the thermostat settings checked. If the
problem persists, call a technician. The pressure should not fall below 1 bar.
If it does, consult the “Heating system pressure” paragraph further on in this
section.
5 - ACV controller (optional)
Refer to the controller instructions if you have this option.
6 - Manual reset safety thermostat
If the boiler temperature exceeds 103 °C, this safety device will shut down
the boiler and the overheat warning light will come on. To restart, the boiler
temperature must fall below 60 °C. Unscrew the cover and press the restart
button using a pen or a similar pointed object, then replace the cover. If the
problem persists, turn the boiler off and call a technician.
