3.1

Preliminary checks

The first ignition should be carried out by expert per-
sonnel from an authorised Technical Assistance Service
Centre. Before starting up the boiler, check:
ƒ that the data of the supply networks (electricity, wa-
ter, gas) correspond to the label data
ƒ that the extraction pipes of the flue gases and the air
suction pipes are working correctly
ƒ that conditions for regular maintenance are guaran-
teed if the boiler is placed inside or between items of
furniture
ƒ the seal of the fuel adduction system
ƒ that the fuel flow rate corresponds to the values re-
quired for the boiler
ƒ that the fuel supply system is sized to provide the
correct flow rate to the boiler, and that it has all the
safety and control devices required by current regu-
lations
ƒ that the circulator rotates freely because, especially
after long periods of non-use, deposits and/or res-
idue may hamper its free movement (see paragraph
"1.10 Manual circulator reset")
ƒ that there is water in the drain-trap (if not, fill it).
After a long period of non-use or following maintenance
work, at the first subsequent ignition (before starting
up the appliance) it is vital to fill the condensate collec-
tion drain-trap by pouring about 1 litre of water into the
boiler combustion analysis outlet and check:
- the safety disc is floating
- the water leaving the boiler via the discharge tube is
running off correctly
- the seal on the condensate discharge connection line
is firm.
When the condensate discharge circuit (pipes and drain-
trap) is working properly, the condensate does not ex-
ceed the maximum level (max). The preventive filling of
the drain-trap, and the presence of the safety disc in-
side this element, aims to prevent the flue gases from
escaping into the room.
High efficiency mode
The boiler is equipped with an automatic function that
is activated at the first power supply or after 60 days
of non-use (electrically powered boiler). In this mode
the boiler, for 60 minutes, limits the heating power to a
minimum and the maximum DHW temperature to 55 ° C.
Activating the chimney sweep temporarily disables this
function.
The function is managed by parameter P7.08, which is
set by default to 0 (function not active).
During execution, the function is shown on the display
with the word HEM and, if P1.05 = 1, with the scrolling
message "HIGH EFFICIENCY MODE".

Programming the boiler

ƒ Turn the main system switch ON.
ƒ Open the gas tap to allow fuel to flow.
If necessary, the interface goes automatically to the clock
menu. The main page shows the icons
lit up, along with ENTER, and the first two digits of the
clock (00:00) will be flashing (0.5 sec ON, 0.5 sec OFF).
To set the time and day, proceed as follows:
ƒ set the hour using the
