Instructions prior to installation
This boiler is designed to heat water at a lower than boiling temperature at atmospheric
pressure. The boiler must be connected to a central heating system and to a domestic
hot water supply system in compliance with its performances and output power.
Have the boiler installed by a Qualied Service Engineer and ensure the following ope-
rations are accomplished:
a) accurate purging of the whole pipework in order to remove any deposits.
b) careful checking that the boiler is t for operation with the type of gas available. For
more details see the notice on the packaging and the label on the appliance itself.
c) careful checking that the ue terminal draft is appropriate; that the terminal is not
obstructed and that no other appliance exhaust gases are expelled through the same
ue duct, unless the ue is especially designed to collect the exhaust gas coming from
more than one appliance, in conformity with the laws and regulations in force.
d)
careful checking that, in case the ue has been connected to pre-existing ue ducts,
thorough cleaning has been carried out in that residual combustion products may
come off during operation of the boiler and obstruct the ue duct.
Instructions prior to commissioning
Initial lighting of the boiler must be carried out by a licensed technician. Ensure the
following operations are carried out:
a) compliance of boiler parameters with (electricity, water, gas) supply systems settin-
gs.
b) compliance of installation with the laws and regulations in force.
c) appropriate connection to the power supply and grounding of the appliance.
Failure to observe the above will render the guarantee null and void.
Prior to commissioning remove the protective plastic coating from the unit. Do not use
any tools or abrasive detergents as you may spoil the painted surfaces.
Commissioning
of the boiler
To correctly light the burner proceed as follows:
1) provide power supply to the boiler;
2) open the gas cock;
3) turn the selector switch (1) to set the boiler on summertime (
) or wintertime (
) operation;
4) turn the central heating (12) and domestic hot water (13) adjusting controls in order
to light the main burner.
To increase temperature values turn the control clockwise and anticlockwise to
decrease it.
When on summertime operation (
) the main burner and the pump will start running
only when there is a call for hot water.
Instructions pertaining to the user

Warning: During initial lighting, until the air contained in the gas pipes is not released,
the burner may fail to light immediately and that may cause a ‘blockage’ of the boiler.
Under such circumstances we recommend you repeat the ignition procedure until gas is
delivered to the burner, and briey set knob (1) to (
) (also see gure 4).

Room temperature adjustment
The system must be equipped with a room thermostat (see the relevant regulations) to
control the temperature in the rooms.
In case there is no room thermostat, during initial lighting, it will be possible to control
the room temperature by turning control (12).
To increase temperature values turn the control clockwise and anticlockwise to decrease
it. Electronic modulation of the ame will enable the boiler to reach the set temperature
by adapting the gas supply to the burner to the actual heat exchange demand.
DHW temperature
adjustment
The gas valve is provided with an electronic ame-modulating function, which operates
depending on the DHW temperature adjusting control (13) settings and on the quantity
of water drawn from the taps.
This electronic device allows to keep the water coming out of the boiler at a constant
temperature also when small quantities of water are drawn.
To increase temperature values turn the control clockwise and anticlockwise to de-
crease it.
Filling the boiler
Important: Regularly check that the pressure displayed by the pressure gauge (14) is
0.7 to 1.5 bar, with boiler not operating. In case of overpressure, open the boiler drain
valve (Figure 3b).
In case the pressure is lower open the boiler lling tap (Figure 3a).
We recommend you open the tap very slowly in order to let off the air.
During this operation, the Summer/Winter selector (ref. 1, gure 4) must be in the OFF
position (0)
In case pressure drops occur frequently have the boiler checked by a Qualied Service
Engineer.
Figure 3a
Figure 3b
The boiler is supplied with a hydraulic differential pressure sensor, which blocks the boiler
in case water is lacking or the pump is blocked.
Turning off the boiler
The electric supply to the boiler must be removed in order to switch it off. When the
selector (1) is in position (0) the boiler stays off, but the voltage remains present in the
electric circuits of the apparatus.
Prolonged standstill of the system
Frost protection
(central heating system)
We recommend you avoid draining the whole system as water replacements engen-
der purposeless and harmful limestone deposits inside the boiler and on the heating
elements.
In case the boiler is not operated during wintertime and is therefore exposed to danger of
frost we suggest you add some specic-purpose anti-freeze to the water contained in the
system (e.g.: propylene glycole coupled with corrosion and scaling inhibitors).
The electronic management of boilers includes a ‘frost protection’ function in the central
heating system which operates the burner to reach a heating ow temperature of 30° C
when the system heating ow temperature drops below 5°C.
The frost protection function is enabled if:
* electrical supply to the boiler is on;
* the gas service cock is open;
* the system pressure is as required;
* the boiler is not blocked.
Gas change
These boilers produced for natural gas can be converted to work with LPG.
Any gas change must be effected by a Qualied Service Engineer.

*
This boiler can be connected to any type of double- or single feeding pipe convector
plates, radiators, thermoconvectors. Design the system sections as usual though
taking into account the available output / pump head performances, as shown on
page 50.
* Do not leave any packaging components (plastic bags, polystyrene, etc.) within
children’s reach as they are a potential source of danger.
*
Initial lighting of the boiler must be effected by a Qualied Service Engineer.
Failure to observe the above will render the guarantee null and void.
Instructions prior to installation
This boiler is designed to heat water at a lower than boiling temperature at atmospheric
pressure. The boiler must be connected to a central heating system and, on models
withis option, to a domestic hot water supply system in compliance with its performances
and output power.
Before connecting the boiler have the following operations effected:
a)
careful checking that the boiler is t for operation with the type of gas available. For
more details see the notice on the packaging and the label on the appliance itself.
b) careful checking that the ue terminal draft is appropriate; that the terminal is not
obstructed and that no other appliance exhaust gases are expelled through the same
ue duct, unless the ue is especially designed to collect the exhaust gase coming
from more than one appliance, in conformity with the laws and regulations in force
c)
careful checking that, in case the ue has been connected to pre-existing ue ducts,
thorough cleaning has been carried out in that residual combustion products may
come off during operation of the boiler and obstruct the ue duct.
To ensure correct operation of the appliance and avoid invalidating the guarantee, observe
the following precautions
1.
Hot water circuit
if the water hardness is greater than 20 °F (1 °F = 10 mg calcium carbonate per litre of
water) install a polyphosphate or comparable treatment system responding to current
regulations
2.
Heating circuit
2.1. new system
Before proceeding with installation of the boiler, the system must be cleaned
and ushed out thoroughly to eliminate residual thread-cutting swarf, solder and
solvents if any, using suitable proprietary products
2.2.
existing system:
Before proceeding with installation of the boiler, the system must be cleaned
and ushed out to remove sludge and contaminants, using suitable proprietary
products
To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-
acid and non-alkaline (e.g. SENTINEL X400 and X100), proceeding strictly in accordance
with the maker’s directions
Remember that the presence of foreign matter in the heating system can adversely affect
the operation of the boiler (e.g. overheating and noisy operation of the heat exchanger)
The template to fix the boiler on the wall
Decide upon the boiler location, then tape the template on the wall.
Connect the pipework to the gas and water inlets prearranged on the template lower
bar.
We suggest you t two G3/4 stop cocks (available on demand) on the central heating
system ow and return pipework; the cocks will allow to carry out important operations
on the system without draining it completely.
If you are either installing the boiler on a pre-existent system or substituting it, we
suggest you also t settling tanks on the system return pipework and under the boiler
to collect the deposits and scaling which may remain and be circulated in the system
after the purge.
When the boiler is xed on the template connect the ue and air ducts (ttings supplied
by the manufacturer) according to the instructions given in the following sections.
When installing the 2.24 CF model boiler with natural draught, make the connection to the
ue using a metal pipe which will provide resistance over time to the normal mechanical
stresses, heat and the effects of the combustion products and any condensation they
form.

...coaxial flue - air duct (concentric)
This type of duct allows to disengage exhaust gases and to draw combustion air both
outside the building and in case a LAS ue is tted.
The 90° coaxial bend allows to connect the boiler to a ue-air duct in any direction as it
can rotate by 360°. It can moreover be used as a supplementary bend and be coupled
with a coaxial duct or a 45° bend.
(*) The restrictor must be removed in case the ue duct length exceeds 1 m.
If the ue outlet is placed outside, the ue-air ducting must protrude at least 18mm out
of the wall to allow alluminium weathering tile to be tted and sealed to avoid water
leakages.
Ensure a minimum downward slope of 1 cm towards the outside per each metre of
duct length.
A 90° bend reduces the total duct length by 1 metre.
A 45° bend reduces the total duct length by 0.5 metre.

This type of ducting allows to disengage exhaust ue gases both outside the building
and into single ue ducts.
Comburant air may be drawn in at a different site from where the ue terminal is lo-
cated.
The splitting kit consists of a ue duct adaptor (100/80) and of an air duct adaptor.
For the air duct adaptor t the screws and seals previously removed from the cap.
The restrictor must be removed in case you install separated ue and air duct termi-
nals.
The 90° bend allows to connect the boiler to ue-air ducting regardless of direction as it
can be rotated by 360°. It can moreover be used as a supplementary bend to be coupled
with the duct or with a 45° bend.

flue air control adjustment
The adjustment of this control is required to optimise performance and combustion param-
eters. The air suction coupling can be rotated to adjust excess air according to the total
length of the ue and intake ducts for the combustion air.
Turn this control clockwise to increase excess combustion air and anticlockwise to
decrease it.
The maximum length of the suction duct must be 10 metres.
If the ue duct exceeds 6 m, the condensate collection kit (supplied as an accessory)
must be tted close to the boiler.
To improve optimisation a combustion product analyser can be used to measure the CO
2
contents of the ue at maximum heat output, gradually adjusting air to obtain the CO
2
reading in the table below, if the analysis shows a lower value.
To properly install this device, also refer to the technical data accompanying the tting.
Separated horizontal flue terminals installation options
IMPORTANT: Ensure a minimum downward slope of 1 cm toward the outside per each

Gas change modalities
A Qualied Service Engineer may adapt this boiler to operate with natural gas (G. 20) or
with liquid gas (G. 30, G. 31).
The procedure for calibrating the pressure regulator may vary according to the type of
gas valve tted (HONE
YWELL or SIT; see gure 12).
Carry out the following operations in the given sequence:
A) substitute the main burner injectors;
B)
change the modulator voltage;
C) proceed with a new max. and min. setting of the pressure adjusting device.
A) Substitute the main burner injectors
• carefully pull the main burner off its seat;
• substitute the main burner injectors and make sure you tighten them fast to avoid
leakage. The nozzle diameters are specied in table 2.
B)
Change the modulator voltage
• remove the 2 screws securing the control board cover and hinge it upward;
• set the jumper or the switch, according to the type of gas used, as described in the
chapter on page 52.
C) Pressure adjusting device setting
• connect the positive pressure test point of a differential (possibly water-operated)
manometer to the gas valve pressure test point (Pb) (Figure 12); connect, for sealed
chamber models only, the negative pressure test point of the manometer to a “T”
tting in order to join the boiler adjusting outlet, the gas valve adjusting outlet (Pc)
and the manometer. (The same measurement can be carried out by connecting the
manometer to the pressure test point (Pb) after removing the sealed chamber front
panel);
If you measure the pressure of burners by different means you may obtain an altered
result in that the low pressure created in the sealed chamber by the fan would not
be taken into account.
C1) Adjustment to rated output
• open the gas tap and rotate knob (1) to set the boiler to the Winter setting ( );
• open a hot water tap to reach a minimum 10 l/minute ow rate or ensure that maximum
heating requirements are set;
•
remove the modulator cover;
• adjust the tube brass screw (A) Fig. 13 to obtain the pressure settings shown at table
1 on page 51;
• check that boiler feeding dynamic pressure, as measured at the inlet gas valve
pressure test point (Pa) (Figure 12) is correct (30 mbar for G.30, 37 mbar for G.31,
20 mbar for natural gas);
C2) Adjustment to reduced heat output
• detach the modulator feeding cable and unscrew the (B) Fig. 13 screw to reach the
pressure setting corresponding to reduced heat output (see table 1 on page 51);
• connect the cable again;
• t the modulator cover and seal.
C3) Final checks
• apply the additional dataplate, specifying the type of gas and settings applied.

Control and operation devices
The boiler has been designed in full compliance with European reference standards and
in particular is equipped with the following:
• Central heating temperature adjustment potentiometer
This potentiometer sets the central heating ow max. temperature. Its temperature
range goes from 30 °C min. to 80 °C max.
To increase the temperature turn knob (12) clockwise and anticlockwise to decrease
it.
• Domestic hot water temperature adjusting potentiometer
This potentiometer sets the domestic hot water max. temperature. Its temperature
range goes from 35 °C min. to 55 °C max according to the water inlet ow rate.
To increase the temperature turn knob (13) clockwise and anticlockwise to decrease
it.
• Air pressure switch for forced draft models (2.24 FF)
This switch allows the main burner to switch on provided the exhaust ue duct
efciency is perfect.
In the event of one of the following faults:
• the ue terminal is obstructed
• the venturi is obstructed
• the fan is blocked
• the connection between the venturi and the air pressure switch is not active
the boiler will stay on stand-by and the light (4) will ash.
• Overheat thermostat (2.24 CF)
Thanks to a sensor placed on the heating ow, this thermostat interrupts the gas ow
to the main burner in case the water contained in the primary system has overheated.
Under such conditions the boiler is blocked and relighting (briey rotating selector
(1) to position (
) will only be possible after the cause of the anomaly has been
removed.
It is forbidden to disenable this safety device
• Flame ionization detector
The ame sensing electrode, placed on the right of the burner, guarantees safety of
operation in case of gas failure or incomplete interlighting of the main burner. Under
such conditions the boiler is blocked. Rotate selector (1) briey to position (
) to
restore normal operating conditions.
• Hydraulic pressure sensor
This device enables the main burner only to be switched on if the system pressure
is over 0.5 bars.
•
Supplementary running of the pump
The electronically-controlled supplementary running of the pump lasts 3 minutes,
when the boiler is in the central heating mode, after the burner has switched off due
to a room thermostat or intervention.
• Frost protection device (central heating system)
Boilers electronic management includes a “frost protection” function in the central
heating system which operates the burner to reach a heating ow temperature of
30°C when the system heating ow temperature drops below 5 °C.
This
function is enabled when the electrical supply to the boiler is on, the gas supply
is on and the system pressure is as required.
•
Pump-blocking prevention
In case there is no call for heat either from the central heating system for 24 hours
on end the pump will automatically switch on for 10 seconds.
This function is enabled if the electrical supply to the boiler is on.
• Hydraulic safety valve (heating circuit)
This device is set to 3 bar and is used for the heating circuit.
The safety valve should be connected to a siphoned drain. Use as a means of draining
the heating circuit is strictly prohibited.

Check of combustion parameters
The boiler has two connection points specically designed to allow technicians to
measure the combustion efciency after installation and ensure that the combustion
products do not constitute a health risk, as required by Italian Presidential Decree n.
412 of 26
th
August 1993.
One connection point is connected to the ue gas discharge circuit, and allows monitoring
of the quality of the combustion products and the combustion efciency.
The other is connected to the combustion air intake circuit, allowing checking of any
recycling of the combustion products in case of coaxial pipelines.
The following parameters can be measured at the connection point on the ue gas
circuit:
• temperature of the combustion products;
• oxygen (O2) or carbon dioxide (CO2) concentration;
• carbon monoxide(CO) concentration.
The combustion air temperature must be measured at the connection point on the air
intake circuit, inserting the measurement probe to a depth of about 3 cm.
For natural draught boiler models, a hole must be made in the ue gas discharge pipe at
a distance from the boiler equal to twice the inside diameter of the pipe itself.
The following parameters can be measured through this hole:
• temperature of the combustion products;
• oxygen (O2) or carbon dioxide (CO2) concentration;
• carbon monoxide (CO) concentration.
The combustion air temperature must be measured close to the point where the air
enters the boiler.
The hole, which must be made by the person in charge of operating the system when it
is commissioned, must be sealed in a way which ensures that the combustion product
discharge pipe is airtight during normal operation.
Output / pump head performances
This is a high static head pump t for installation on any type of single or double-pipe
heating systems. The air vent valve incorporated in the pump allows quick venting of
the heating system.
