CONNECTION TO THE GAS PIPELINE
Once connected the burner to the gas pipeline, it is necessary to control that this last is perfectly sealed. Also verify that
the chimney is not obstructed. Open the gas cock and carefully bleed the piping through the pressure gauge connector,
then check the pressure value trough a suitable gauge. Power on the system and adjust the thermostats to the desired
temperature. When thermostats close, the sealing control device runs a seal test of valves; at the end of the test the bur-
ner will be enabled to run the start-up sequence.
BURNER START-UP
Before starting the burner, make sure it is mounted correctly. Then check connections are correct according to the dia-
gram and piping is appropriate to the system. Before connecting the burner to the electricity supply, make sure voltage
corresponds to burner plate data. The connection diagram and start-up cycle are shown separately. For wiring from
control box to burner, see the enclosed connection diagram. Pay particular attention to neutral and phase connections :
never exchange them!. Vent air and impurities of gas pipe. Check gas pressure conforms to the limits stated on the bur-
ner plate when connecting a master gauge to the test port provided on the burner. Blower motor starts and pre-purging
begins. Since pre-purging has to be carried out with the max. air delivery, the burner control circuit turns the air dam-
per to the max. delivery position by the air servocontrol in approximately 30 seconds time. When the servocontrol is
fully open, a signal to the electronic control unit starts the 66 seconds pre-purge cycle. At the end of the prepurging
time, the air servocontrol gets to the Low Flame position so that burner ignition is ensured at min. output.
Simultaneously the ignition transformer receives voltage and after 3 seconds (pre-ignition) opens the pilot gas valve.
Fuel flows to the combustion head and ignites. Two seconds after pilot gas valves have opened, the ignition transformer
is excluded from the circuit. In case of no ignition the burner goes to lock-out within two seconds. After 6 sec. open the
working gas valve, governed by the gas firing butterfly valve.Now the burner is operating at the min. firing rate (about
30% of the max. firing rate). The air servocontrol runs at the Low Flame position and in case the temperature control
has to be set at the max. output it goes to a fully open position of air damper and butterfly valve. During the burner-off
periods the air damper closes up fully.
ELECTRICAL CONNECTIONS
All burners factory tested at 400 V 50 Hz three-phase for motors and 230 V 50 Hz monophase with neutral for auxi-
liary equipment. If mains supply is 230 V 50 Hz threephase withuot neutral, change position of connectors on burner
as in fig. Protect burner supply line with safety fuses and any other devices required by safety standards obtaining in the
country in question.
ADJUSTING THE COMBUSTION PROCESS
IMPORTANT: to obtain the right adjustment of the combustion and thermal capacity it is important to analyze the reducts of
combustion with the aid of suitable instruments. The combustion and thermal capacity adjustment is done simultaneously,
together with the analysis of the products of combustion, making sure that the measured values are suitable and that they comply
with current safety standards. On this matter, please refer to the table and figure below.
THESE OPERATIONS MUST BE DONE BY PROFESSIONALLY-QUALIFIED TECHNICIANS.

The control box starts the burner
fan, to carry out the prepurging
of the combustion chamber, and
cheks the vent air pressure throu-
gh the air pressure switch. At the
end of prepurging, the ignition
transformer cuts-in and generates
a spark between the electrodes.
At the same time the two gas valves open (Vs safety valve and Vl Low flame working valve). The total safety, in case of missed
ignition or casual burner's flame-out, is granted by a ionisation probe which cuts-in and sets the burner shutdown within the
safety time. In case of gas lack or a major pressure drop, the minimum air pressure switch shuts down the burner.

Adjusting the maximum gas flow rate (see figure on solenoid valve adjustments) or adjust the gas pressure in the gover-
nor.
ADJUSTING THE MAXIMUM AIR FLOW RATE
Adjusting the maximum air flow rate (see figure, detail 2). Loosen the nut holding the air damper transmission rod;
The correct air flow as established by analyzing the combustion process.
ADJUSTING THE INTERMEDIATE BURNER CAPACITY
Using the selector, start the servomotor (closing or opening) and position on 0 to stop the stroke; the adjustment is
made as outlined below. Repeat the operation for the other cam points.
Adjustment the intermediate gas flow rates (see figure, detail 3): - using a suitable Allen wrench, change the position of
the cam guide blade; if you screw it down, the flow rate is reduced; if you unscrew it, the flow rate increases.

ADJUSTMENT OF GAS MINIMUM PRESSURE SWITCH
Unscrew off and remove cover M. - Set regulator N to a value equal to 60% of gas nominal feed pressure
(i.e. for nat. gas nom. pressure = 20 mbar, set regulator to a value of 12 mbar; for L.P.G. nom.
pressure of G30/G31- 30/37 mbar, set regulator to a value of 18 mbar).Screw up cover M
ADJUSTMENT OF THE AIR PRESSURE SWITCH
Unscrew screws A and B and remove cover C.- Set the pressure switch to the minimum by
turning regulator D to position 1.
- Start the burner and keep in low flame running, while checking that combustion is cor-
rect. Through a small cardboard, progressively obstruct the air intake until to obtain a CO2 increase of
0,5÷0,8% or else, if a pressure gauge is available, connected to pressure port E, until reaching a
pressure drop of 1 mbar (10 mm of W.G.). - Slowly increase the adjustment value of the air
pressure switch until to have the burner lockout. Remove the obstruction from the air intake,
screw on the cover C and start the burner by pressing the control box rearm button.
Note: The pressure measured at pressure port E must be within the limits of the pressure
switch working range. If not, loose the locking nut of screw F and gradually turn the
same: clockwise to reduce the pressure; counterclockwise to increase. At the end tighten the
locking nut.

IGNITION END IONIZATION ELECTRODES
Ionization Probe
Ignition Electrode
The ionization current is checked by inserting a
microammeter with an end of scale of 50 µA (d.c.)
in series with the ionization probe. A faulty posi-
tion of the electrode can lead to a reduction in the
ionization current and cause a safety cut-out of the
burner due to a flame detection failure. In this case,
check the position of the electrode, its electric con-
nection and the earthing of the burner. The ioniza-
tion current is normally > 20 µA.

режде чем зажечь горелку, следует убедиться, что ее монтаж был выполнен правильно. роверить соответствие
схемам электросоединений и состояние трубопроводов системы отопления. о подачи электроэнергии убедиться, что
напряжение соответствует параметрам, указанным на табличке технических характеристик. Электрическая схема и
пусковой цикл описаны отдельно. ля подключения к горелке панели управления смотрите прилагаемую схему.
Особое внимание следует уделить положению нуля и фазы: ни в коем случае не менять их местами! роверить
заземление системы отопления. ля трехфазных двигателей обязательно проверить направление вращения
(указано стрелкой). родуть газопровод для удаления из него посторонних веществ и стравить из него воздух.
Удостовериться, что давление газа находится в пределах, указанных на табличке. Это делается с помощью
поверочного манометра, который устанавливается в специальное гнездо отбора давления на горелке. атем
запускается двигатель, и начинается предварительная продувка горелки. римерно за 30 сек. сервопривод
полностью открывает воздушную заслонку. огда заслонка оказывается в полностью открытом положении, по
импульсу, поступающему на аппаратуру управления, начинается цикл предварительной продувки
продолжительностью около 66 сек. о завершении продувки сервопривод перемещает заслонку в положение первой
ступени, после чего становится возможен розжиг горелки на минимальной мощности. Одновременно с этим подается
напряжение на трансформатор розжига, и спустя 3 сек. (предварительный розжиг) напряжение подается на
пилотный клапан. пустя 2 сек. после открывания пилотного клапана. трансформатор исключается из электрической
цепи. сли розжиг не происходит, не более чем через 2 сек. происходит аварийная остановка горелки. россельный
клапан регулирует расход газа в огневой головке. орелка работает на минимальной мощности (около 30% от
максимальной). одуляционное устройство управляет сервоприводом: в зависимости от потребности системы
отопления сервопривод переходит в положение максимального раскрытия либо останавливается в среднем
положении. а счет изменения положения сервопривода гарантируется пропорциональность расхода газа и воздуха
таким образом, что при любой мощности (30% - 100%) обеспечивается оптимальное качество сгорания.
ри выключении горелки сервопривод возвращается в положение "закрыто".
