FIRST START-UP
5.1
Filling the installation
Use a filling valve to fill the installation slowly until the pressure shown on the thermohydrometer is
between 1 - 1.5 bar.
5.2
Checking the circulating pump functioning
Unscrew the circulating pump cap so that the rotation shaft is visible. Connect the boiler main
switch and check if the pump shaft is turning. Screw the cap back on.
If the shaft is not turning, switch off the boiler main switch and use a suitable screwdriver to turn
the pump shaft in both directions to unblock it. Turn on the main switch again and check the shaft
is turning. Screw the cap back on.
5.3
Bleed the air from the installation
Connect the boiler main switch and drain the air from the installation and the boiler using the air
vent valves provided in the installation and on the boiler.

INSTALLATION DELIVERY
The installer will explain how the boiler functions to the user, making all necessary observations such
as how to fill, bleed and drain the boiler.
6.1
Observations
If the boiler does not start up when you have checked that the power is reaching it, the installation
is filled with water at the correct pressure, the circulating pump is turning and the boiler has not
been cut out by the safety circuit breaker, turn off the main switch and contact the installer.

OPERATION
7.1
Power setting selection
The total power to the boiler may be reduced by half, using the half-power switches on the control
panel. When both switches are connected, the boiler will function at maximum power.
7.2
Temperature selection
This is done using the control thermostat command on the control panel. Turn it clockwise for a
higher temperature, or anticlockwise for a lower temperature. When the selected temperature is
reached, it will automatically be kept constant by the thermostat.
To regulate the room temperature you will need to install a room thermostat. This thermostat
switches off the boiler when the selected temperature is reached, and starts it up again when the
temperature drops.
The boiler is pre-wired for connection of a room thermostat. To do this, remove the bridge from the
connector block and connect the room thermostat.
