    Instuctionspiotoinstallation

    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 sstem and to a domestic

    hot water suppl sstem in compliance with its perormances and output power.

    Have the boiler installed b a Qualied Service Engineer and ensure the ollowing ope-

    rations are accomplished:

    a) accurate purging o the whole pipewor in order to remove an deposits.

    b) careul checing that the boiler is t or operation with the tpe o gas available. For

    more details see the notice on the pacaging and the label on the appliance itsel.

    c) careul checing that the fue terminal drat is appropriate; that the terminal is not

    obstructed and that no other appliance exhaust gases are expelled through the same

    fue duct, unless the fue is especiall designed to collect the exhaust gas coming rom

    more than one appliance, in conormit with the laws and regulations in orce.

    d) careul checing that, in case the fue has been connected to pre-existing fue ducts,

    thorough cleaning has been carried out in that residual combustion products ma

    come o during operation o the boiler and obstruct the fue duct.

    Instuctionspiotocommissioning

    Initial lighting o the boiler must be carried out b a licensed technician. Ensure the

    ollowing operations are carried out:

    a) compliance o boiler parameters with (electricit, water, gas) suppl sstems settin-

    gs.

    b) compliance o installation with the laws and regulations in orce.

    c) appropriate connection to the power suppl and grounding o the appliance.

    Failure to observe the above will render the guarantee null and void.

    Prior to commissioning remove the protective plastic coating rom the unit. Do not use

    an tools or abrasive detergents as ou ma spoil the painted suraces.

    Commissioning

    roomtempeatueadjustment

    The sstem 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 b turning control (12).

    To increase temperature values turn the control clocwise and anticlocwise to decrease

    it. Electronic modulation o the fame will enable the boiler to reach the set temperature

    b adapting the gas suppl to the burner to the actual heat exchange demand.

    DHWtempeatue

    adjustment

    The gas valve is provided with an electronic fame-modulating unction, which operates

    depending on the DHW temperature adjusting control (13) settings and on the quantit

    o water drawn rom the taps.

    This electronic device allows to eep the water coming out o the boiler at a constant

    temperature also when small quantities o water are drawn.

    To increase temperature values turn the control clocwise and anticlocwise to de-

    crease it.

    Fillingtheboile

    Important: Regularl chec that the pressure displaed b the pressure gauge (14) is

    0.7 to 1.5 bar, with boiler not operating. In case o overpressure, open the boiler drain

    valve (Figure 3b).

    In case the pressure is lower open the boiler lling tap (Figure 3a).

    We recommend ou open the tap ver slowl in order to let o the air.

    During this operation, the Summer/Winter selector (re. 1, gure 4) must be in the OFF

    position (0)

    In case pressure drops occur requentl have the boiler checed b a Qualied Service

    Engineer.

    Figue3a

    Figue3b

    The boiler is supplied with a hdraulic dierential pressure sensor, which blocs the boiler

    in case water is lacing or the pump is bloced.

    Tuningotheboile

    The electric suppl to the boiler must be removed in order to switch it o. When the

    selector (1) is in position (0) the boiler stas o, but the voltage remains present in the

    electric circuits o the apparatus.

    Polongedstandstillothesstem

    Fostpotection

    (centalheatingsstem)

    We recommend ou avoid draining the whole sstem as water replacements engen-

    der purposeless and harmul limestone deposits inside the boiler and on the heating

    elements.

    In case the boiler is not operated during wintertime and is thereore exposed to danger o

    rost we suggest ou add some specic-purpose anti-reeze to the water contained in the

    sstem (e.g.: proplene glcole coupled with corrosion and scaling inhibitors).

    The electronic management o boilers includes a rost protection unction in the central

    heating sstem which operates the burner to reach a heating fow temperature o 30 C

    when the sstem heating fow temperature drops below 5C.

    The rost protection unction is enabled i:

    * electrical suppl to the boiler is on;

    * the gas service coc is open;

    * the sstem pressure is as required;

    * the boiler is not bloced.

    Gaschange

    These boilers produced or natural gas can be converted to wor with LPG.

    An gas change must be eected b a Qualied Service Engineer.

    necessar to wait some minutes at each intervention o the central heating temperature

    adjusting control (5). To relight the main burner immediatel place the selector switch (1)

    on (0) and then again on ( ). No waiting is needed when the boiler is in the DHW mode

    on models with this option.

    The ollowing remars and instructions are addressed to Service Engineers to help them

    carr out a aultless installation. Instructions regarding lighting and operation o the boiler

    are contained in the Instructions pertaining to the user section.

    Note that installation, maintenance and operation o the domestic gas appliances must be

    perormed exclusivel b qualied personnel in compliance with current standards.

    Please note the ollowing:

    * This boiler can be connected to an tpe o double- or single eeding pipe convector

    plates, radiators, thermoconvectors. Design the sstem sections as usual though

    taing into account the available output / pump head perormances, as shown on

    page 50.

    * Do not leave an pacaging components (plastic bags, polstrene, etc.) within

    childrens reach as the are a potential source o danger.

    * Initial lighting o the boiler must be eected b a Qualied Service Engineer.

    Failure to observe the above will render the guarantee null and void.

    Instuctionspiotoinstallation

    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 sstem and, on models

    withis option, to a domestic hot water suppl sstem in compliance with its perormances

    and output power.

    Beore connecting the boiler have the ollowing operations eected:

    a) careul checing that the boiler is t or operation with the tpe o gas available. For

    more details see the notice on the pacaging and the label on the appliance itsel.

    b) careul checing that the fue terminal drat is appropriate; that the terminal is not

    obstructed and that no other appliance exhaust gases are expelled through the same

    fue duct, unless the fue is especiall designed to collect the exhaust gase coming

    rom more than one appliance, in conormit with the laws and regulations in orce

    c) careul checing that, in case the fue has been connected to pre-existing fue ducts,

    thorough cleaning has been carried out in that residual combustion products ma

    come o during operation o the boiler and obstruct the fue duct.

    To ensure correct operation o the appliance and avoid invalidating the guarantee, observe

    the ollowing precautions

    1.Hotwatecicuit

    i the water hardness is greater than 20 F (1 F = 10 mg calcium carbonate per litre o

    water) install a polphosphate or comparable treatment sstem responding to current

    regulations

    2.Heatingcicuit

    2.1. new sstem

    Beore proceeding with installation o the boiler, the sstem must be cleaned

    and fushed out thoroughl to eliminate residual thread-cutting swar, solder and

    solvents i an, using suitable proprietar products

    2.2. existing sstem:

    Beore proceeding with installation o the boiler, the sstem must be cleaned

    and fushed out to remove sludge and contaminants, using suitable proprietar

    products

    To avoid damaging metal, plastic and rubber parts, use onl neutral cleaners, i.e. non-

    acid and non-alaline (e.g. SENTINEL X400 and X100), proceeding strictl in accordance

    with the maers directions

    Remember that the presence o oreign matter in the heating sstem can adversel aect

    the operation o the boiler (e.g. overheating and nois operation o the heat exchanger)

    Thetemplatetotheboileonthewall

    Decide upon the boiler location, then tape the template on the wall.

    Connect the pipewor to the gas and water inlets prearranged on the template lower

    bar.

    We suggest ou t two G3/4 stop cocs (available on demand) on the central heating

    sstem fow and return pipewor; the cocs will allow to carr out important operations

    on the sstem without draining it completel.

    I ou are either installing the boiler on a pre-existent sstem or substituting it, we

    suggest ou also t settling tans on the sstem return pipewor and under the boiler

    to collect the deposits and scaling which ma remain and be circulated in the sstem

    ater the purge.

    When the boiler is xed on the template connect the fue and air ducts (ttings supplied

    b the manuacturer) according to the instructions given in the ollowing sections.

    When installing the 2.24 CF model boiler with natural draught, mae the connection to the

    fue using a metal pipe which will provide resistance over time to the normal mechanical

    stresses, heat and the eects o the combustion products and an condensation the

    orm.

    The adjustment o this control is required to optimise perormance and combustion param-

    eters. The air suction coupling can be rotated to adjust excess air according to the total

    length o the fue and intae ducts or the combustion air.

    Turn this control clocwise to increase excess combustion air and anticlocwise to

    decrease it.

    The maximum length o the suction duct must be 10 metres.

    I the fue duct exceeds 6 m, the condensate collection it (supplied as an accessor)

    must be tted close to the boiler.

    To improve optimisation a combustion product analser can be used to measure the CO

    In the event o one o the ollowing aults:

    the fue terminal is obstructed

    the venturi is obstructed

    the an is bloced

    the connection between the venturi and the air pressure switch is not active

    the boiler will sta on stand-b and the light (4) will fash.

    Overheat thermostat (2.24 CF)

    Thans to a sensor placed on the heating fow, this thermostat interrupts the gas fow

    to the main burner in case the water contained in the primar sstem has overheated.

    Under such conditions the boiler is bloced and relighting (brief rotating selector

    (1) to position ( ) will onl be possible ater the cause o the anomal has been

    removed.

    It is orbidden to disenable this saet device

    Flame ionization detector

    The fame sensing electrode, placed on the right o the burner, guarantees saet o

    operation in case o gas ailure or incomplete interlighting o the main burner. Under

    such conditions the boiler is bloced. Rotate selector (1) brief to position ( ) to

    restore normal operating conditions.

    Hdraulic pressure sensor

    This device enables the main burner onl to be switched on i the sstem pressure

    is over 0.5 bars.

    Supplementar running o the pump

    The electronicall-controlled supplementar running o the pump lasts 3 minutes,

    when the boiler is in the central heating mode, ater the burner has switched o due

    to a room thermostat or intervention.

    Frost protection device (central heating sstem)

    Boilers electronic management includes a rost protection unction in the central

    heating sstem which operates the burner to reach a heating fow temperature o

    30C when the sstem heating fow temperature drops below 5 C.

    This unction is enabled when the electrical suppl to the boiler is on, the gas suppl

    is on and the sstem pressure is as required.

    Pump-blocing prevention

    In case there is no call or heat either rom the central heating sstem or 24 hours

    on end the pump will automaticall switch on or 10 seconds.

    This unction is enabled i the electrical suppl to the boiler is on.

    Hdraulic saet valve (heating circuit)

    This device is set to 3 bar and is used or the heating circuit.

    The saet valve should be connected to a siphoned drain. Use as a means o draining

    Checkocombustionpaametes

    The boiler has two connection points specicall designed to allow technicians to

    measure the combustion ecienc ater installation and ensure that the combustion

    products do not constitute a health ris, as required b Italian Presidential Decree n.

    412 o 26

    th

    August 1993.

    One connection point is connected to the fue gas discharge circuit, and allows monitoring

    o the qualit o the combustion products and the combustion ecienc.

    The other is connected to the combustion air intae circuit, allowing checing o an

    reccling o the combustion products in case o coaxial pipelines.

    The ollowing parameters can be measured at the connection point on the fue gas

    circuit:

    temperature o the combustion products;

    oxgen (O2) or carbon dioxide (CO2) concentration;

    carbon monoxide(CO) concentration.

    The combustion air temperature must be measured at the connection point on the air

    intae circuit, inserting the measurement probe to a depth o about 3 cm.

    For natural draught boiler models, a hole must be made in the fue gas discharge pipe at

    a distance rom the boiler equal to twice the inside diameter o the pipe itsel.

    The ollowing parameters can be measured through this hole:

    temperature o the combustion products;

    oxgen (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 b the person in charge o operating the sstem when it

    is commissioned, must be sealed in a wa which ensures that the combustion product

    discharge pipe is airtight during normal operation.
