Appliance shut-o conditions
The boiler is protected from malfunctions by means of internal
checks performed by the electronic P.C.B., which stops the boiler
from operating if necessary. In the event of the boiler being shut o
in this manner, a code appears on the control panel display which
refers to the type of shut-o and the reason behind it.
Two types of shut-o may occur:
Safety shut-o
This type of error is “volatile”, which
means that the boiler starts up again
automatically as soon as the problem
which caused the shut-o is removed;
Err” and the error code
(e.g. Err/110)
)  ash on the display and the
symbol appears.
In fact, soon as the cause of the shut-o
disappears, the boiler starts up again
and continues to operate normally.
If the boiler still indicates a safety shut-
o , switch it o . Make sure the external electric switch is in the OFF
position, shut o the gas valve and contact a quali ed technician.
Safety shut-o due to insu cient water pressure
If the water pressure inside the heating
circuit is insu cient, the boiler will
perform a safety shut-o .
Code 108 (e.g. Err/108) will appear
on the display, in addition to the
symbol.
The system may be restarted,
re-balancing the value, by using the
 lling valve.
If the re-balancing request is
performed on a frequent basis, switch
the boiler o , bring the external
electric switch to the OFF position, shut o the gas valve and contact
a quali ed technician to check for any leaks of water.
Operation shutdown
This type of error is “non-volatile”, which means that it is not removed
automatically.
On the display  ash Err and the error code (es. Err/501), and
appears RESET whit the symbol
.
In this case the boiler does not restart automatically, but it may be
reset by pressing the RESET button.
If the problem manifests itself again after several attempts to reset
the appliance, contact a quali ed technician.
Important
If this shutdown occurs frequently, contact an authorised service
centre for assistance. For safety reasons, the boiler will allow
a maximum of 5 reset operations to take place in 15 minutes
(individual presses of the RESET button).
If the shutdown is occasional or an isolated event, this is not
Necessarily a problem.

Anti-frost Device.
The anti-frost function acts on the central heating  ow temperature probe,
independently from other settings, when the electrical supply is turned on.
If the primary circuit temperature falls below 8°C the pump will run for 2
minutes.
After the two minutes of circulation ( xed) the
boiler will check the following:
a - if the central heating  ow temperature is >
8°C, the pump stops;
b - if the central heating  ow temperature is
between 4 and 8°C, the pump will run for
another two minutes;
c - if the central heating  ow temperature is <
4°C, the burner will  re (heating position)
at minimum power until the temperature
reaches 33°C, the burner will go o and
the pump will continue to run for two
minutes.
L’attivazione della sicurezza antigelo è
segnalata sul display dal simbolo
.
The anti-frost device activates only when (with the boiler operating correctly):
- the system pressure is correct;
- the boiler is electrically powered;
- there is a supply of gas.
Change of gas type
Our boilers are designed to function either with Natural Gas
(methane) or L.P.G. gas.
The models 5R are designed to function
either with 5R gas or 7R gas. If you need to change from one gas to
the other, one of our Authorised Service Centres must be contacted
to convert the appliance.
Maintenance
Schedule an annual maintenance check-up for the boiler with a
competent person.
Correct maintenance always results in savings in the cost of running
the system.
