FILLING INSTRUCTIONS
A method for initially filling the system and replacing lost water
during servicing and initial filling (in accordance with current Water
Regulations), is provided as an integral part of the connection kit
(see Fig. 3.1).
To fill the system and replace lost water it is necessary to proceed
as follows:
-
Switch off the power to the boiler;
-
Ensure that the flexible hose is connected to both the cold
water inlet connection and the C.H. flow connection;
-
Open the black lever on the valve for the C.H. flow connection
and slowly open the black handle on the valve for the cold water
inlet until water is heard passing through the valves;
-
Once the pressure gauge
37
(Fig. 2.1) reads between 1 and
1.5 bar close the levers on both the cold water connection and the
C.H. flow connection
-
Switch the power to the boiler back on.

CONDITIONS FOR STOPPAGE OF THE BOILER
This boiler is fitted with safety devices which are activated in certain situations
and cause the boiler to stop operating.
There are two types of stoppage:
- Operating failure (A)
- Safety stop (E)
OPERATING STOPPAGE "A"
This type of stoppage is displayed in the form of a number preceded by a
letter (A) as shown in the following table.
To clear this type of stoppage, press the reset button (
Reset
).
In the table, each error code is associated with the problem causing it to
appear.
In the case of error
A 02
, before
calling a qualified technician, check
the pressure gauge to see if the
water pressure in the appliance is 1
bar. If necessary, restore the
pressure using the filling valve
located under the boiler and perform
an ON/OFF operation by pressing
the button. If the pressure falls
frequently in the appliance, have a
plumber check for water leaks.
N.B. Warning! The boiler is always
connected to an electrical supply.
IMPORTANT
If this type of failure occurs too often,
call an approved after sales technical
service. For safety reasons, the
boiler will only allow 5 reignition
attempts in 15 minutes (pressing of
the RESET button). After the fifth
attempt, the boiler goes into safety
shutdown mode E 99.
This is therefore not a problem in the
case of sporadic or isolated
stoppages.
SAFETY SHUTDOWN “E”
In the event of a safety shutdown, indicated by display of the letter E followed by a
number, there is no need to take action. The boiler will automatically attempt to reset and
restart. If this does not occur, call a qualified technician. Switch off the boiler as described
in the previous paragraph, close the gas tap and move the external electrical supply
switch to the OFF position.
Antilocking of pump and three-way valve
To prevent locking of the components, the appliance performs a self-test every 24 hours:
the pump starts up for 3 seconds and the diverting valve is operated.
