Adjusting heating water temperature
Turning the selector A(g.18),afterhavingpositionedtheselector
mode on winter or winter comfort , it is possible to regulate
the heating water temperature.
Switching on
Switch on the boiler as follows:
- access the gas tap through the slots in the cover located in the
lower part of the boiler
- openthegastapbyturningitanti-clockwise(g.15)
- power the boiler.
- press the function selector until the indicator moves to the re-
quired function , depending on the kind of operation chosen.
- WINTER : with the selector in this position, the heating water
and domestic hot water functions are activated.
 InthispositiontheS.A.R.A.functionisenabledintheheating
mode (see chapter “Boiler functions”). The boiler actives the
temperature stabiliser in order to ensure the continuous produc-
tion of domestic hot water, even for small demands or when the
inlet water is already hot. This prevents temperature oscillations
duetotheburnerswitchingoff/on.
- WINTER COMFORT : with the selector in this position, as
well as the traditional function of heating water and domestic hot
water, the preheating function is also activated which keeps the
waterinthedomestichotwaterexchangerhotinordertoreduce
waiting times. The S.A.R.A. Booster and Domestic hot water
preheatingfunctionsareenabledinthisposition(seechapter
“Boilerfunctions”).
- SUMMER :with the selector in this position, just the tradi-
tional domestic hot water function is activated.
- SUMMER COMFORT : with the selector in this position, the
boiler provides just domestic hot water with a temperature stabi-
liser for small deliveries. Ideal at the times of year or in the areas
where the mains water is already warm. In these conditions, the
temperature of the hot water produced by a boiler with just tradi-
tionalfunctions(seeSUMMERandWINTERCOMFORT)may
be instable.

Inthiscase,contacttheTechnicalAssistanceCentre.
The boiler turns on in the status it was in before it was swi-
tched off: if the boiler was in the winter comfort mode when
it was switched off, it will turn on again in the winter comfort
mode.IfitwasintheOFFmode,thedisplaywillshowtwo
segmentsinthecentralarea(g.17).Pressthe button to
enable operation.
Turn clockwise to increase the temperature and anticlockwise to
decrease.Thebarsegmentslightup(every5°C)asthetempera-
ture is increased. The selected temperature value appears on the
display.IfyouentertheS.A.R.A.adjustmenteld(from55to65

andthegraduatedscalestartashing.Theselectedtemperature
value appears on the display.
Adjusting heating water temperature with an external sensor
connected
Whenanexternal probeisconnected,thevalue ofthedelivery
temperature is automatically chosen by the system which rapidly
adjustsambienttemperaturetothechangesinexternaltemperature.
Justthecentralsegmentofthebarisilluminated(g.19).
To increase or decrease the temperature with respect to the value
automatically calculated by the electronic board, turn the heating
water selector clockwise to increase and anticlockwise to decrea-
se.Thebarsegmentslightup(ateverycomfortlevel),correction
toleranceliesbetween-5and+5comfortlevels(g.19).When
choosing the level of comfort, the digit area of the display shows
the required level of comfort while the bar shows the matching
segment(g.20).
Adjusting domestic hot water temperature
To adjust domestic hot water temperature, turn switch B(g.21)
clockwise to increase and anticlockwise to decrease. The bar seg-
mentslightup(every3°C)asthetemperatureisincreased.
The selected temperature value appears on the display.
When choosing the temperature, both for heating and domestic
hot water, the display shows the value being selected. About4
secondsaftertheselectionhas been made, themodicationis
memorised and the display returns to the delivery temperature
read by the probe.

PARAMETERS
It is easy to convert from one gas family to another even after the
boiler has been installed. This operation must be performed by
professionallyqualiedstaff.Theboilerisdesignedtoworkwith
naturalgasorLPG.Theproductplateindicateswhichfuelithas
beenttedouttouse.
It is possible to convert the boiler from one kind of gas to the other
using kits which can be supplied on request:
- naturalgastoLPGconversionkit
- LPGtonaturalgasconversionkit.
To disassemble, proceed as follows:
- disconnect the boiler from the power supply and close the gas
tap
- remove the components to access to the internal parts of the
boiler(g.79-80)
- disconnect the sparkplug cable
- removetheburnerxingscrewsandremovethelatterwiththe
spark plug attached and corresponding cables
- removethenozzlesandwasherswithasocketorforkwrench
and replace them with the ones in the kit
 Usethewasherscontained in the kitevenforwasherless
collectors.
- put back the burner into the combustion chamber and tighten
thescrewsxingittothegascollector
- reconnect the spark plug cable
- remount components previously removed
- powertheboilerandopenthegastap(withtheboilerworking,
checktherearenoleaksinthegassupplycircuit).
Programmethe“Gastype”parameterandadjusttheboiler as
describedinthe“Adjustments”chapter.
The boiler may only be converted by qualied staff.
After conversion, adjust the boiler again as shown in the
relative paragraph and apply the new rating plate contai-
ned in the kit.
13 - GAS CONVERSION
To ensure the product remains in perfect working order, and to
comply with current legislation, systematically check the boiler at
regular intervals.
To analyse combustion, proceed as follows:
-access the CALIBRATION & SERVICE phase by setting the
passwordasindicatedinchapter“Adjustments”
- turnthedomestichotwatertemperatureselectortomaximum
heatingpower(parameterHH).
 Theboilerworksatmaximumpowerfor4minutes.
- the hole for inserting analysis instruments must be made in the
section of straight pipe immediately after it leaves the hood in
compliancewithcurrentlaw(A,g.81a).
The fumes analysis probe must be fully inserted.
IMPORTANT: the function that switches off the boiler when water
temperaturereachesamaximumofabout90°Cisstillenabled
during the combustion analysis phase.

reil; le fabricant décline toute responsabilité en cas de préju-
dices causés par une erreur ou l’absence de mise à la terre.
Pourlebranchementélectriqueutilisezle câble d’alimentation
fourni.Lethermostatd’ambianceet(ou)l’horloge-programmateur
sebranchentdelafaçonindiquéesurleschémaélectrique.
Si vous remplacez le câble d’alimentation, utilisez un câble de
type HAR H05V2V2-F, 3 x 0,75.
6 - REMPLISSAGE ET VIDANGE DE
