boiler
To have access to the control system of the boiler, open the transparent
panel which covers the control panel. The panel rotates down.
To open the upper door of the boiler pull on its upper corners so that the
door will be released from the outer casing.
To correctly light the boiler proceed as follows:
• Provide power supply to the boiler;
• Open the gas cock;
• Verify that the system is full of water and the pressure is the right one
(see point 7);
• Turn the selector switch (ref. 1 fi gure 1) to set the boiler on
operation.
• Regulate the room thermostat (if present) at the desired temperatu-
re.
• Set the Central Heating regulation knob (ref. 2 fi gure 1) in order to
have the boiler at the desired temperature.
For a better energy saving we suggest you to set the regulation knobs in
the "COMFORT" position, environment conditions permitting.
Important: when selector is set to
to wait few minutes every time the heating regulation device switches
off the burner (ref. 2 fi gure 2). If you want the burner to switch on im-

4.1 Operation with Water Storage Tank Unit
The boiler water adjustment knob (Ref. 3 Figure 1) is only active when
there is a Tank unit. In this case it is possible to adjust the domestic
hot water temperature by turning the knob onto the required hot water
setting.
With the summer/winter selector set to winter mode
water of the tank has reached the selected temperature, the boiler works
automatically for the heating system (priority is given to the domestic
hot water supply).
It is possible to exclude the sanitary mode just setting the knob (ref. 3
fi gure 1) to the minimum value, that corresponds to the anti-frost function
of the tank.
With the summer/winter selector set to summer mode
alight and the tank's pump works only when the temperature of the water
inside the tank is less than the value set with the DHW knob.
