AIR INTAKE (Quadra ie m)
FILLING THE HEATING SYSTEM
See diagram in fig. 4 showing the various reference
components.
After making the water connections, fill the heating
system.
Do this when the system is cold as follows:
- open the cap of the automatic air vent (A) by two or
three turns
- make sure that the cold water inlet tap is open
- open the filling tap (B) until the pressure on the
thermohydrometer (fig. 5) must range between 1 and
1.5 bar.
Then close the filling tap.
As the boiler features an efficient air separator, no
manual operations are required.
The burner only ignites if the air has finished venting.
DRAINING THE HEATING SYSTEM
To drain the heating system proceed as follows:
- switch off the boiler
- loosen the boiler drainage valve (C)
- empty out the bottom parts of the system
DRAINING THE DOMESTIC HOT WATER SYSTEM
If there is the risk of freezing, drain the domestic hot
water system as follows:
- close the general water tap
- open all the hot and cold water taps
- svuotare i punti più bassi.
ATTENTION
The safety valve outlet must be connected to an
appropriate drainage system.
The manufacturer will not be held liable for eventual
flooding due to interfering with the safety valve.
The boiler is fitted with a fumes thermostat for checking
that the products of combustion are correctly
discharged. In the event of a fault, it promptly shuts
down the appliance.
This control system must never be tampered with.
Safety devices may only be replaced by the
Technical Assistance Service which only uses
original spare parts.
After repairing the device, perform an ignition test
and check that the fumes outlet thermostat works
properly.
The fumes outlet and the flue connection must
comply with standards and/or with local and
national regulations.
Rigid ducts must be used, the connections
between the elements must be airtight and all the
components must be resistant to high
temperatures, condensate and mechanical stress.

the room must comply with technical standards.
It is forbidden to obstruct or reduce the size of the
ventilation openings in the room.
7. FUMES OUTLET AND COMBURENT
AIR INTAKE (Quadra ie FF m)
Refer to standards and laws in force for evacuation of
combustion products.
A centrifuge fan located inside the combustion chamber
evacuates combustion products and it is constantly
controlled by a pressure switch to make sure it works
properly.
CONCENTRIC OUTLETS (Ø 60-100)
The boiler is supplied complete with a place for
connecting up the coaxial exhaust/suction ducts and
with the opening for air inlet (M) closed – (fig. 8).
The coaxial flue ducts can be turned in any direction
best suited to room requirements, keeping to maximum
lengths given in the table.
See instructions given in the kit for installation.
Fig. 8 shows the reference quotas for marking out the
Ø 105 mm opening through the wall with respect to the
boiler supporting plate.
A flange will have to be inserted depending on the length
of the flue duct used, selecting it from amongst those
in the boiler (see table given here below). Fig. 8

CONCENTRIC OUTLETS (Ø 80-125)
The boiler is furnished predisposed for connection to
concentric outlets/inlets and with the air aspiration
aperture closed.
The concentric outlets may be oriented in the direction
best suited to the requirements of the premises,
respecting the maximum lengths indicated at the table
below. For installation, follow the instructions provided
with the kit.
Execute a Ø 140 mm hole for transit through the wall.
Depending on the length of ducts used, it is necessary
to insert a flange selecting one from those contained in
the boiler (see table below).
Particular care is required with the external temperature
and the length of the pipe. Refer to the graphics to
establish whether the condensation trap is mandatory
or not.
In the case of operation at boiler temperatures below
60 °C, the use of a condensation trap is mandatory.
In the case of use of condensation trap the fumes
discharge pipe must be inclined by 1% towards the trap.
Connect the condensation trap siphon to a white water
outlet pipe.
Non insulated discharge pipes are potential sources of
danger.

Fig. 13
Fig. 14
There is a LED on the control panel, previously
described as the “Boiler status LED”, which changes
colour depending on the operating status of the
appliance: green LED, red LED and yellow LED.
Green LED
- Flashing 1 second on - 5 seconds off = boiler on
stand-by, no flame.
- Flashing 0,5 seconds on – 0,5 seconds off = appliance
temporarily stopped due to the following automatically
resettable faults:
- water pressure switch (waiting time abt. 10 minutes)
- differential air pressure switch (waiting time abt. 10
minutes)
- transitory waiting for ignition.
In this phase, the boiler waits for operating
conditions to be reset. If the boiler does not start
working properly after the waiting time has elapsed,
it stops permanently and the red LED lights up.
- Rapid flashing with brief visualisation, access to the
S.A.R.A. (Automatic Ambient Adjustment System)
function.
Turning the heating water temperature selector to the
range given in fig. 13 – temperature measuring from
55 to 65°C – starts up the S.A.R.A. self-regulating
system: the boiler changes the delivery temperature
by a signal to switch off given by the room thermostat.
A countdown of 20 minutes starts upon reaching the
temperature set by the heating water temperature
selector.
If in the meantime the room thermostat keeps asking
for more heat, the set temperature will be
automatically increased by another 5°C.
Another countdown of 20 minutes begins once the
new set temperature has been reached.
This new temperature value is the result of the
temperature set manually with the heating water
temperature selector and the +10 °C increase of the
S.A.R.A. function.
After the second increase cycle, the temperature
value remains unchanged until the request for heat
terminates and interrupts the cycle.
After another heat request, the boiler will work at the
temperature set with the heating water temperature
selector.
- A fixed green light indicates that the flame is present
and the boiler is working correctly.
Red LED
The red LED steady indicates that the boiler has blocked
due to one of the following faults:
- flame blocked
- ACF electronic fault alarm
- fumes thermostat (Quadra ie m)
- differential air pressure switch (after the transitory
phase) (Quadra ie FF m)
- NTC heating probe
- water pressure switch (after the transitory phase)
Flashing = Limit thermostat working
Turn the programme selector to off-set to start up again,
wait for 5-6 seconds and then turn it to the desired
position: summer or winter.
Yellow LED
Steady = problem with hot water NTC gauge. Only
displayed when boiler in stand-by.
The boiler works normally, but cannot guarantee a
regular hot water temperature.
Call in the Service Centre for a check.
Flashing = “chimney sweep” programme working.

G. S.A.R.A. SYSTEM
Turning the heating water temperature selector (C) to
the range given in figure 2, will activate the S.A.R.A.
self-regulating system: the boiler will automatically
change the temperature of the central heating water on
the basis of the temperature set by the room thermostat
and the time needed to reach it, reducing service time,
making it easier to work and saving on energy.
The boiler will work at the temperature set by the heating
water temperature selector (C) the next time it has to
heat up again.
H. CONTROLS
Make sure the heat-water gauge reads pressures
between 0.6 and 1.5 bar when the system is cold at the
start of the central heating season and every now and
again while it is being used.
The boiler will turn itself off if there is insufficient water
in circulation. The water pressure must never for any
reason drop to below 0.5 bar (red range).
Should this occur the pressure of the water in the boiler
must be taken back to normal again by:
turning the programme selector (D) to .
opening the filling stopcock underneath the boiler until
pressure returns to normal.
carefully turning off the filling stopcock again.
turning the programme selector (D) back to its original
position.
