Instructions pertaining to the user - INSTRUCÿIUNI PENTRU UTILIZATOR
Instructions prior toinstallationThis boiler is designed to heat water at a lower than boiling temperatureat atmospheric pressure. The boiler must be connected to a central heatingsystem and to a domestic hot water supply system in compliance withits performances and output power.Have the boiler installed by a Qualified Service Engineer and ensure thefollowing operations are accomplished:
a) accurate purging of the whole pipework in order to remove anydeposits.
b) careful checking that the boiler is fit for operation with the type ofgas available. For more details see the notice on the packaging andthe label on the appliance itself.
c) that the terminal is not obstructed and that no other appliance exhaustgases are expelled through the same flue duct, unless the flue isespecially designed to collect the exhaust gas coming from more thanone appliance, in conformity with the laws and regulations in force.
d) careful checking that, in case the flue has been connected to pre-existing flue ducts, thorough cleaning has been carried out in thatresidual combustion products may come off during operation of theboiler and obstruct the flue duct thus engendering dangerous situations.
Instructions prior tocommissioningInitial 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 settings.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 theunit. Do not use any tools or abrasive detergents as you may spoil thepainted surfaces.
Commissioningof the boilerTo 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 (5) and domestic hot water (6) adjusting
controls in order to light the main burner.To increase temperature values turn the control clockwise andanticlockwise to decrease it.When on summertime operation ( ) the main burner and the pumpwill start running only when there is a call for hot water.

The control panel on the boiler model 1.240 Fi is not equipped withknob (6) for the regulation of domestic water temperature.In the event of installing a BAXI boiler, also refer to the instructionsprovided with the appliance.
Warning: During initial lighting, until the air contained in the gas pipesis not released, the burner may fail to light immediately and that maycause a ‘blockage’ of the boiler. Under such circumstances we recommendyou repeat the ignition procedure until gas is delivered to the burner, andand set knob (1) briefly to ( ) (also see figure 4).
Room temperatureadjustmentThe system must be equipped with a room thermostat (see the relevantregulations) to control the temperature in the rooms.In case there is no room thermostat, during initial lighting it will bepossible to control the room temperature by turning control (5).To increase temperature values turn the control clockwise andanticlockwise to decrease it. Electronic modulation of the flame willenable the boiler to reach the set temperature by adapting the gas supplyto the burner to the actual heat exchange demand.
DHW temperatureadjustmentFor models 240 i and 240 Fi
The gas valve is provided with an electronic flame-modulating function,which operates depending on the DHWtemperature adjusting control (6)settings and on the quantity of waterdrawn from the taps.This electronic device allows to keep thewater coming out of the boiler at aconstant temperature also when smallquantities of water are drawn.
To ensure energy saving and economicalmanagement of your boiler, werecommend you place the switchadjusting the hot water temperature on“--comfort--” (see figure 2). Inwintertime it will be necessary toincrease the DHW temperatureaccording to needs.

Umplerea cazanului cu apaIMPORTANT: Verificati regulat daca presiunea arata demanometru (7) este intre 0.5 – 1 bar, c<nd boilerul nufunctioneaza. In caz de suprapresiune, deschide^i valva de drenaj.In cazul in care presiunea este mica deschide^i robinetul deumplere (fig. 3) pentru modelele 240 I si 240 Fi.
Recomandam sa deschide^i robinetul de umplere foarte ¶ncetpentru a permite evacuarea aerului.In cazul in care presiunea scade frecvent boilerul trebuie verificatde c™tre un tehnician autorizat.

Centrala este dotata cu un presostat hidraulic diferen^ial, carenu va permite func^ionarea cazanului in cazul in care existascurgeri sau pompa este blocata.
Oprirea cazanuluiPentru ¶nchiderea boilerului roti^i butonul (1) in pozi^a „0”, astfelalimentarea cu energie electrica a cazanului va fi ¶ntrerupta.
Neutilizarea o perioadaindelungata. Prote≠ia la inghet(sistemul de ¶nc™lzire centrala)Recomandam sa evita^i evacuarea totala a apei, deoarece aceastapoate cauza depunerea de calcar in interiorul boilerului si peelementele de ¶nc™lzire.In cazul in care boilerul nu functioneaza in perioada de iarna side aceea exista pericolul de inghet va recomandam sa introduce^iin apa o substan^a anti inghet (ex: propilena glicol combinata cuinhibitori corozivi si de depuneri)
Schimbarea gazuluiCazanul poate fi alimentat at<t cu gaz metan cat si cu GPL.Schimb™rile privitoare la tipul de combustibil cu care sealimenteaz™ cazanul trebuie executate numai de personal calificatsi autorizat.
The boiler is supplied with a hydraulic differential pressure sensor, whichblocks the boiler in case water is lacking or the pump is blocked.
Turning off the boilerTo turn off the boiler turn the selector switch (1) on (0); you will thusisolate the electrical supply to the boiler.
Prolonged standstill of thesystem.Frost protection (centralheating system)We recommend you avoid draining the whole system as waterreplacements engender purposeless and harmful limestone deposits insidethe boiler and on the heating elements.In case the boiler is not operated during wintertime and is thereforeexposed to danger of frost we suggest you add some specific-purposeanti-freeze to the water contained in the system (e.g.: propylene glycolecoupled with corrosion and scaling inhibitors).
Gas changeThese boilers produced for natural gas can be converted to work withLPG.Any gas change must be effected by a Qualified Service Engineer.
Filling the boilerImportant: Regularly check that the pressure displayed by the pressuregauge (7) is 0.5 to 1 bar, with boiler not operating. In case of overpressure,open the boiler drain valve.In case the pressure is lower open the boiler filling tap (figure 3) formodels 240 i and 240 Fi.The boiler filling tap on the model 1.240 Fi, is fitted by the installer onthe lower section of the unit (see ref. 9 figure 17 on page 23).We recommend you open the tap very slowly in order to let off the air.In case pressure drops occur frequently have the boiler checked by aQualified Service Engineer.

of a differential (possibly water-operated) manometer to the gas valvepressure test point (Pb) (Figure 12);connect, for sealed chamber modelsonly, the negative pressure test point ofthe manometer to a “T” fitting in orderto join the boiler adjusting outlet, the gasvalve adjusting outlet (Pc) and themanometer. (The same measurement canbe carried out by connecting themanometer to the pressure test point (Pb)after removing the sealed chamber frontpanel);If you measure the pressure of burnersby different means you may obtain analtered result in that the low pressurecreated in the sealed chamber by the fanwould not be taken into account.
• open the gas tap and rotate knob (1) toset the boiler to the Winter setting ( );
• open a hot water tap to reach a minimum 10 l/minute flow rate orensure that maximum heating requirements are set;
• remove the cap from the valve and adjust the pressure regulator screw(Pmax) in figure 12 to obtain the pressure values as specified in table1 on page 17;
• check that boiler feeding dynamic pressure, as measured at the inletgas valve pressure test point (Pa) (Figure 12) is correct (30 mbar forG.30, 37 mbar for G.31, 20 mbar for natural gas);
• re-fit the cap on the valve.
B2) Adjustment to reduced heat output:• Set Winter/Summer selector (1) to position (0);• Disconnect the NTC probe;• set selector (1) to Winter and ensure heating activation;• connect the NTC probe;• adjust screw (Pmin) on the gas valve (figure 12) to obtain the pres-
sure value set for minimum power (table 1 on page 17). This opera-tion must be performed within 25 second after which the boilerresumes normal operation.
B3) Final checks• apply the additional dataplate, specifying the type of gas and settings
applied;• seal the cap on the pressure regulator in the event of use with LPG.

Control and operationdevicesThe boiler has been designed in full compliance with European referencestandards and in particular is equipped with the following:
• Central heating temperature adjustment potentiometerThis potentiometer sets the central heating flow max. temperature.Its temperature range goes from 30 °C min. to 85 °C max.To increase the temperature turn knob (5) clockwise and anticlockwiseto decrease it.
• Domestic hot water temperature adjusting potentiometer (not fiitedon model 1.240 Fi)This potentiometer sets the domestic hot water max. temperature. Itstemperature range goes from 35 °C min. to 65 °C max according tothe water inlet flow rate.To increase the temperature turn knob (6) clockwise and anticlockwiseto decrease it.
• Air pressure switch for models 240 Fi and 1.240 FiThis switch allows the main burner to switch on provided the exhaustflue duct efficiency is perfect.In the event of one of the following faults:• the flue terminal is obstructed• the venturi is obstructed• the fan is blocked• the connection between the venturi and the air pressure switch is
not activethe boiler will stay on stand-by.
• Flue thermostat for model 240 iThis device has a sensor positioned on the left section of the flueextraction hood and shuts off the gas flow to the main burner if theflue duct is obstructed or in the event of draught failure.Under such conditions the boiler is blocked and relighting (by meansof button in Figure 6 page 7) will only be possible after the cause ofthe anomaly has been removed.
• Overheat thermostatThanks to a sensor placed on the heating flow, this thermostatinterrupts the gas flow to the main burner in case the water containedin the primary system has overheated. Under such conditions the boileris blocked and relighting (by means of button in Figure 5 page 7) willonly be possible after the cause of the anomaly has been removed.
It is forbidden to disenable this safety device
• Flame ionization detectorThe flame sensing electrode, placed on the right of the burner,guarantees safety of operation in case of gas failure or incompleteinterlighting of the main burner.Under such conditions the boiler is blocked.Rotate selector (1) briefly to position ( ) to restore normal operatingconditions.
• Hydraulic differential pressure sensorThis pressure sensor, fitted on the hydraulic assembly, allows themain burner to light provided the pump head is as required and protectsthe flue-water exchanger from possible lacks of water or blockingsof the pump.
• 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 a a meansof draining the heating circuit is strictly prohibited.

Check of combustionparametersTo measure combustion performance and hygiene levels of combustionproducts, the forced draught boiler models are equipped with two testpoints on the tapered coupling specifically designed for this purpose.One of the two test points is connected to the exhaust flue duct to allowmeasurements of the combustion products hygienic standards andcombustion efficiency.The second test point is connected to the comburant air inlet duct tocheck possible combustion products circulation in case of coaxial ducts.The exhaust flue duct test point allows measurements of the following:• combustion products temperature;• concentration of oxygen (O
2) or, alternatively, of carbon dioxyde
(CO2);
• concentration of carbon monoxyde (CO).The comburant air temperature must be measured at the test pointconnected to the air inlet duct.
For natural draught models a hole should be drilled on the flue exhaustduct at a distance from the boiler that is twice the internal diameter of theduct.This hole enables readings of the following values:• combustion product temperature;• concentration of oxygen (O
2) or alternatively of carbon dioxide (CO
2);
• concentration of carbon monoxide (CO).Measurements of the combustion air temperature must be taken in thevicinity of the boiler air inlet.The hole, to be made by the head of the system on initial unit set-up andmust be closed off to guarantee comnbustion product extraction sealingefficiency during normal operation.

din circuitul de apa calda menajera- inchideti ie`irea circuitului de apa calda menajera;- desface^i cei doi robinet de oprire- scoate^i filtrul
Daca ansamblul nu este livrat cu robinet este necesara scoatereaschimb™torului apa-apa pentru purjare.Recomandam curatarea suportului schimb™torului si senzorulNTC al sistemului.
How to purge the DHWsystem from limestonedeposits(Not applicable on model 1.240 Fi)
To clean the DHW system it is not necessary to remove the DHW heatexchanger if the assembly is equipped with the appropriate taps (suppliedon demand) placed on the hot water outlet and inlet.
To carry out the purge it is necessary to:• close the cold water inlet• drain the DHW system from the water contained therein by means of
a hot water tap• close the DHW outlet• unscrew the two stop cocks caps• remove the filters.
In case the appropriate tap is not supplied it is necessary to disassemblethe DHW heat exchanger, as described in the following section, and dothe purge aside. We recommend you also purge from limestone depositsthe DHW heat exchanger seat and the NTC sensor fitted on the DHWsystem.To purge the exchanger and/or the DHW system we suggest the use ofCillit FFW-AL or Beckinser HF-AL.
