Initial procedures
To guarantee safety and the correct operation of the appliance, the
boiler must be prepared for operation by a qualifi ed technician who
possesses the skills which are required by law.
Electricity supply
- Check that the voltage and frequency of the electricity supply
correspond to the data shown on the boiler data plate;
- Make sure that the earthing connection is effi cient.
Filling the hydraulic circuit
Proceed in the following manner:
- Open cold water inlet tap;
- Lift the cap on the automatic air relief valve on the circulation
pump;
- Gradually open the valve under the boiler
- Open each air release tap starting with the lowest point and close it only
when clear water, free of air, is visible.
-
Clause the valve under the boiler when at least 1 bar registers on
the pressure gauge.
Gas supply
Proceed in the following manner:
- make sure that the main gas supply uses the same type of gas as
indicated on the boiler data plate;
- Open all doors and windows;
- Make sure there are no sparks or naked fl ames in the room;
- Make sure that the system does not leak fuel using a cut-off valve
inside the boiler itself which should be closed and then opened
while the gas valve is disabled. The meter must not show any signs
of gas being used for 10 minutes.

First ignition
1. Make sure that:
- The gas valve is closed;
- The electrical connection has been properly carried out. Make
sure that, in any case, the
green/yellow
earthing
is connected to an effi cient
earthing system;
- Use a screwdriver to lift the cap
on the automatic air relief valve;
-
the system pressure is at least 1
bar on the pressure gauge
-
Switch on the boiler (by pressing
the ON/OFF button) and select
the standby mode, where no
hot water or heating requests
are made.
-
Start the deaeration cycle by
pressing MODE for 10 seconds
The boiler will start a deaeration cycle lasting about 7 minutes. If
you need to stop it press MODE.
-
At the end, check that the system is completely deaerated and, if
not, repeat the procedure.
-
Check whether the siphon contains water; if not, it must be
refi lled.
N.B.: if the boiler will not be used for long periods, the
siphon should be fi lled before the boiler is started up again.
It is dangerous not to refi ll the siphon as fumes may be
released into the environment.
-
Bleed the air from the radiators;
-
The exhaust duct for combustion products should be suitable
and free from any obstructions;
-
Any necessary ventilation inlets in the room should be open
(type B installation).
2. Open the gas valve and check the connection seals, including
the boiler connection seals, making sure that the meter does not
detect any passage of gas. Eliminate any leaks.
3. Start the boiler by selecting the heating or domestic hot water
operation.
Deaeration cycle
During the fi lling stage or if there is excess air in the system,
the deaeration cycle can be activated by holding the MODE
button for 10 seconds. The boiler will start a cycle which lasts
approximately 7 minutes. When this is complete the menu screen
will be restored. The cycle may either be repeated, if necessary,
or stopped by pressing MODE. Press the MODE button until the
normal display screen is restored.
