Operation shutdown
This type of error is "non-volatile", which means that it is not
removed automatically.
On the display flash Err and the error code (es. Err/501), and
appears 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 qualified 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 flow temperature
probe, independently from other regulations, 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 (fixed) the boiler will check
the following:
a) if the central heating flow temperature is > 8°C, the pump
stops;
b) if the central heating flow temperature is between 4 and 8°C,
the pump will run for another two minutes;
c) if the central heating flow temperature is < 4°C, the burner will
fire (heating position) at minimum power until the temperature
reaches 33°C, the burner will go out and the pump will conti-
nue to run for two minutes.
If the flow temperature remains between 4-8°C the pump will
continue to run for two minutes for a maximum of 10 times
unless a temperature above 8°C is detected in the central he-
ating flow, after this the the burner will fire. If lockout is caused
by overheat the burner is kept OFF.
The anti-frost device activates only when (with the boiler opera-
ting correctly):
- the system pressure is correct;
- the boiler is electrically powered;
- there is a supply of gas.
Disposal and recycling boiler.
Our products are designed and manufactured for most of
the components of recyclable materials.
The boiler and its accessories have to be adequately
disposed and the various materials differentiated, where
possible.
The packaging used for the transport of the boiler must
be disposal by the installer / dealer.
ATTENTION!!
Recycling and disposal of the boiler and the
accessories must be made as required by
regulations.
Change of gas type
Our boilers are designed to function either with Natural
Gas (methane) or L.P.G. gas. If you need to change from
one gas to the other, one of our Authorised Service Cen-
tres 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.

appliance will invalidate the second year of the
