INSTRUCTIONS
We recommend that you have your system serviced
each year by a qualified engineer.
Starting the burner:
In normal operation the burner starts automatically if
the temperature of the boiler is below setpoint.
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
1 - Control thermostat
If the boiler is being used to generate hot water only, the boiler
temperature can be set to between 60 and 90°C. If the boiler
is being used for hot water and heating, then the boiler’s control
thermostat should normally be set to 80°C to guarantee optimum
operating conditions.
2 - Main switch
This switch is used to start and stop the boiler
3 - Summer/Winter switch
Switches ON and OFF the heating pump.
4 - Thermometer
The thermometer shows the boiler temperature in the heating
circuit. This temperature should not exceed 90°C. If it does,
stop the boiler and check the settings on the thermostat. If the
problem persists, contact your installer for advice.
5 - ACV climatic controller (optional)
Refer to the instructions supplied with the controller if you have
this option.

PRESSURE IN THE HEATING SYSTEM
The Central Heating pressure must be minimum 1 bar and must
be periodically checked by the end user.
Make sure that the appliance is powered off when filling the
system. To do this, turn the on/off switch. For more information,
please ask your installer when the system is delivered. A safety
valve is provided underneath the appliance. If the system pressure
exceeds 3 bars, this valve opens and drains the water from the
system. In this case, please contact your installer.
The water escaping from the safety valve
can be extremely hot and cause very
serious burns.
