3 COMMISSIONING
Preliminary checks
3.1
The first ignition should be carried out by expert personnel from an
authorised Technical Assistance Service Centre.
Before starting up the boiler, check:
ƒ that the data of the supply networks (electricity, water, gas) cor-
respond 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 guaranteed 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 required 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 devic-
es required by current regulations
ƒ that the circulator rotates freely because, especially after long
periods of non-use, deposits and/or residue may hamper its free
movement (see paragraph "1.7 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 collection 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 exceed the maximum
level (max). The preventive filling of the drain-trap, and the pres-
ence of the safety disc inside 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
