3 COMMISSIONING
3.1 Preliminary checks
The rst ignition should be carried out by expert per-
sonnel from an authorised Technical Assistance Service
Centre. Before starting up the boiler, check:
that the data of the supply networks (electricity, wa-
ter, gas) correspond to the label data
that the extraction pipes of the ue gases and the air
suction pipes are working correctly
that conditions for regular maintenance are guaran-
teed if the boiler is placed inside or between items of
furniture
the seal of the fuel adduction system
that the fuel ow rate corresponds to the values re-
quired for the boiler
that the fuel supply system is sized to provide the
correct ow rate to the boiler, and that it has all the
safety and control devices required by current regu-
lations
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”)
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 rst subsequent ignition (before starting
up the appliance) it is vital to ll 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 oating
- the water leaving the boiler via the discharge tube is
running off correctly
- the seal on the condensate discharge connection line
is rm.
When the condensate discharge circuit (pipes and drain-
trap) is working properly, the condensate does not ex-
ceed the maximum level (max). The preventive lling of
the drain-trap, and the presence of the safety disc in-
side this element, aims to prevent the ue gases from
escaping into the room.
High efciency mode
The boiler is equipped with an automatic function that
is activated at the rst 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”.
3.2 Programming the boiler
Turn the main system switch ON.
Open the gas tap to allow fuel to ow.
If necessary, the interface goes automatically to the clock
menu. The main
page shows the icons ,
, and
lit up, along with ENTER, and the rst two digits of the
clock (00:00) will be ashing (0.5 sec ON, 0.5 sec OFF).
To set the time and day, proceed as follows:
set the hour using the and arrows, then con-
rm with button A
set the minutes using the and arrows, then
conrm with button A
set the day of the week using the and arrows.
The segment corresponding to the selected day will
ash. Press the MENU button in line with the
icon to conrm the time and day setting. The clock
will ash for 4 seconds, then the main screen will be
displayed again.
to quit the time programming function without saving
the new values, just press the button.
NOTE:
the TIME and DAY settings can be modied at any time
by accessing menu P1, parameter P1.02, or by pressing but-
tons A+C for at least 2 seconds.

Every time the boiler is electrically powered, a venting
cycle is run (it lasts 6 min).
