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 burner will be enabled to run the
start-up sequence.
ELECTRICAL CONNECTIONS
All burner motors are tested at 400 V 3phase at 50 Hz, whilst auxiliaries are tested at 230V 1phase at 50 Hz.
Should it be necessary to power the burners at 230V/50Hz 3phase without neutral, carry out the necessary modifications accor-
ding to the burner’s wiring diagram, and check that the thermal relay is within the absorption field of the motor.
BURNER START-UP
Before starting the burner, make sure it is mounted correctly. Then check connections are correct according to the
diagram 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 burner 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 car-
ried out with the max. air delivery, the burner control circuit turns the air damper 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 igni-
tion 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.

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.
NOTE: ALL SAFETY DEVICES (AIR PRESSURE SWITCH, MINIMUM GAS PRESSURE SWITCH, GAS
SOLENOID VALVES AND GAS GOVERNOR) SHALL BE DULY SEALED AFTER CALIBRATION AND
BURNER START UP BY ECOFLAM’S TECHNICIANS.

The control box starts the burner
fan, to carry out the prepurging of
the combustion chamber, and
cheks the vent air pressure through
the air pressure switch. At the end
of prepurging, the ignition tran-
sformer cuts-in and generates a
spark between the electrodes. At
the same time the two gas valves
open (Vs safety valve and Vl 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 PRESSURE REGULATOR
The pressure regulator, complete with its incorporated filter, must be installed to avoid conta-
minants reaching the gas valve. It is important to ensure certain conditions: The pressure of the
gas must not exceed the established maximum pressure. To increase the pressure of the gas sup-
ply, tighten screw C; to reduce the pressure, loosen screw C. After making any adjustments, put
the cap back in place.

LEAKAGE CONTROL DEVICE DUNGS VPS 504-VDK 200
When the thermostats are closed, the gas leakage control device checks the valve seals by pressurizing the circuit
between the two gas valves. When test pressure is reached the device remains in stand-by for about 25 seconds. At
the end of the test the yellow pilot light on the control device lights up and the burner is enabled to carry out the
start-up cycle. If the seal on one of the valves is faulty and this causes a drop in test pressure, the device puts the
system into the safety condition and the red pilot right on the device lights up. The flame
control device starts the burner fan to carry out prewashing of the combustion
chamber,checking fan air pressure via the air pressure switch. After preventilation the ignition
transformer starts operating, generating a spark between the electrodes and simultaneously the
gas valves open (safety gas valve VS and first stage operating valve VL). If the flame does not
ignite or goes out, total safety is ensured by an ionization detection probe. The safety time
limit in the event of no flame is less than 2 seconds at start-up and less than 1 during operation. In the event of no
gas being supplied or of a considerable drop in pressure the minimum gas pressure switch interrupts burner opera-
tion. About 20/30 seconds after ignition the flame control device commands operation of the second stage via the
gas valve and air servocontrol, thus taking the burner to maximum power.

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 pressu-
re 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.

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.
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 position 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 detec-
tion failure. In this case, check the position of the
electrode, its electric connection and the earthing of the burner. The ionization current is normally > 20 µA.

CHECKS TO BE MADE TO ENSURE A PROPER INSTALLATION:
Before proceeding with the filling of the fuel system and subsequent burner start up, it is advisable to carry
out the following checks:
- Power line must be adequate to system’s adsorbed load
- Fuses must be adequate to the system’s load
- Boiler’s thermostats must have been properly connected
- Voltage and frequency must be within the specified limits
- Fuel type must be the one specified by the burner manufacturer
- Feed piping section must be adequate to the requested fuel flow rate
- Filters, cocks as well as fittings must have been properly installed
- Blast tube length must be the one specified by the boiler manufacturer
- Nozzle’s flow rate of the burner must be adequate to boiler’s output
MODULATING OPERATION
With the bumer in the start position and the appliance thermostats enabled, power is delivered to the resi-
stances (G) of the preheater and heating cartridges for the pumps and the fuel supply line to the head (O).
When the preheater thermostat reaches the set value, (usually a minimum of about 90°C is necessary to
guarantee a good level of circulation) the pump start-up is enabled (set point on out
1, if using the GEFRAN 200 thermoregulating device).
If the preheating system of the tank is also equipped for a fluid exchanger (hot water,
steam, diathermic oil) the thermostat may enable a contact in the terminal block for
any stop-start of the fluid electrovalve.
This is not a standard solution as the heated fluid is normally always connected. The pump starts to send
oil (the head has already been heated by its cartridge (O) and therefore has no residue of cold dense oil)
which flows from the tank to the head and then to the return line of the ring.
When the head thermostat reaches the set value (usually about 70-30°C the cycle starts properly and the
control programmer enables start-up. The servomotor sets itself at minimum (see chapter on regulation)
acting on the air and fùel via the pressure regulator on the return.
The electromagnet (A) opens the nozzle (Q) in the followmg condition :
-sparks from the ignition electrodes are generated by the transformer also governed by the burner
control device.
If the cell fails to detect the flame the burner shuts down (with the cyclic control programmer cutting in).
Once ignition has taken place and after the flame stabilisation period, the system starts operating in modu-
lating mode (see chapter 7).
-Before start-up make sure that the pump and delivery pipes are completely filled with hot fuel oil; the
absence of fuel oil can cause pump seizure.
-If there is a block, a specific waring light on the programmer and on the burner front control board
lights up and this signal is usually sent to the main control board of the equipment using the burner,
setting off a buzzer and warning light.
-Afew blocks are normal on first starting up (up to about 4); to release press the button on the
programmer (also found on the front of the bumer control board) for repeating the start cycle. Should
they continue to occur seek the help of a specialised technician.
N.B. The position of the programmer at the time of the block is memorised to supply an indication of the
cause of this block (see detailed instructions attached to Chapter 10).

OIL DELIVERY ADJUSTMENT
The diagram illustrates the fuel feeding system of these type of burners, which incorporates a by-pass nozz-
le with oil flow regulation on its return pipe. The oil supply is varied by acting on the nozzle through the
pressure in the return line. Max. oil supply is therefore reached when the pressure in the pump line is
about 30 bar and the return line is fully closed; min. oil supply when the return line is fully open(see also
diagram BERGONZO). Relevant pressure readings in the return line are as follows (return oil pressure has
to be measured on “M” pressure gauge): - max. oil supply : 20 to 30 bar in the pump.
- min. oil supply : 3 to 24 bar in the return.
