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.
CONNECTION TO GAS PIPE
Once the burner has been connected to the gas supply, check that this last is perfectly sealed. Also verify that the chimney is not
clogged. Open the on-off valve and carefully bleed the piping through the pressure port, then check the pressure value through
a suitable pressure gauge. Turn on the system and adjust the thermostats to the needed temperature. When the thermostats
close, the leakage control device runs a valves leakage test, then enables the burner to start the ignition cycle.
OPERATION OF BURNER WITH GAS MULTICALOR 300.1-400.1
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 carried
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 ensu-
red at min. output. Simultaneously the ignition transformer receives voltage and after 3 seconds (pre-
ignition) opens the gas valve. Fuel flows to the combustion head and ignites, being governed by the
gas firing butterfly valve. Two seconds after gas valves have opened, the ignition transformer is excluded from the circuit. In

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 contaminants
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 supply, tighten screw
C; to reduce the pressure, loosen screw C. After making any adjustments, put the cap back in place.
CALCULATING THE BURNER CAPACITY
To calculate the burner's capacity in kW, proceed as follows: Check the gas flow rate (in liters)
on the counter and the time of the reading in seconds.
Proceed with the calculation using the following formula: x f = kW

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 com-
ply 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.
case of no ignition the burner goes to lock-out within two seconds. 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
dumper closes up fully.

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.

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 yel-
low 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 igni-
tion 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 operation. 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.

OPERATION OF BURNER WITH LIGHT-OIL FUEL MULTICALOR 300.1-400.1
Once installed the burner, check the following items:
- The burner power feeding and the main line protection fuses
- The correct length of pipes and that the same are sealed.
- The type of fuel, which must be suitable for burner.
- The connection of boiler’s thermostats and all the safeties.
- The motor rotation direction.
- The correct calibration of the motor’s thermal protection.
When all the above mentioned conditions are checked and accomplished, it is possible to go on with burner’s tests. Power the
burner. The control box feeds the ignition transformer and the burner’s motor at the same time, which will run a prepurging of
the combustion chamber. At the end of prepurging, the control box powers up the ignition transformer and opens the light-oil
valve, so the burner start . the servomotor will set up to the light-oil ignition position, whilst the control box powers up the
ignition transformer and the “Safety” and “Low flame” solenoid valves. After a safety interval of 2 seconds and a correct igni-
tion, the control box turns off the ignition transformer and, 10 seconds later, sets the motorised air damper to its maximum
opening and opens the 2nd stage solenoid valve (Multicalor 300.1) and 3rd stage solenoid valve (Multicalor 400.1). In case of
faulty ignition,the control box will shut down the burner in 2 sec.
In order to obtain a correct combustion, it shall be necessary to adjust the Low and High flame by following the instructions of
the Air servomotor and firing head adjustment.
During such a phase, it will be possible to manually switch between HIGH and LOW flame and viceversa, through the
High/Low flame switch. At the end of the adjusting phase, leave the switch in position “AUTO”. The fuel pump feeding pres-
sure, must remain around 12 bar.

VERIFY:
- That piping system is perfectly sealed;
- That the use of hoses is avoided whenever is possible (use copper pipes preferably);
- That depression is not greater than 0,45 bar, to avoid pump’s cavitation;
- That check valve is suitably designed for the duty;
The pump pressure is set at a value of 12 bar during the testing of burners. Before starting the burner, bleed the air in the pump
through the gauge port. Fill the piping with light-oil to facilitate the pump priming. Start the burner and check the pump fee-
ding pressure. In case the pump priming does not take place during the first prepurging, with a consequent, subsequent lock-
out of the burner, rearm the burner’s lock-out to restart, by pushing the button on the control box. If, after a successful pump
priming, the burner locks-out after the prepurging, due to a fuel pressure drop in the pump, rearm the burner’s lock-out to
restart the burner. Do never allow the pump working without oil for more than three minutes. Note: before starting the burner,
check that the return pipe is open. An eventual obstruction could damage the pump sealing device.

MAINTENANCE
YEARLY CHECKS
The burner’s periodical check (firing head, electrodes etc.) must be carried out by authorised personnel one or two times per
year, depending on the utilisation. Before going on with the maintenance controls of the burner, it should be advisable to check
its general conditions, according to the following steps:
Unplug the burner; close the fuel cock; shut down the gas supply; remove burner’s cover and clean the fan and air intake; clean
the firing head and check the electrode’s position; reassemble all the parts; check the connection’s sealing; check the chimney;
start the burner and check the combustion flue (CO2 = 9.5 ÷ 9.8; O = lower than 75 ppm).
BEFORE EVERY INTERVENTION CHECK:
The electric system is duly powered and the burner is plugged in.
The gas pressure must be the suitable one and the gas cock open.
The control devices must be properly connected.
When all the above conditions are met, start the burner by pressing the lockout enable pushbutton.
Check the burner’s cycle.
THE BURNER DOES NOT START:
Check the ON/OFF switch, the thermostats, the motor and the gas pressure.
The master switch is in position “0”. Fuses are blown out.
The control box is faulty.
THE BURNER RUNS THE PREPURGING AND SWITCHES TO LOCKOUT AT THE END OF CYCLE:
Check the fan and the air pressure.
Check the air pressure switch.
Control box faulty. Ignition transformer faulty.
Check the ignition cable. Electrodes are dirty or in wrong position.
Nozzles are clogged or worn. Filters are clogged. Light-oil pressure is too low.
Combustion air’s flow rate too high related to nozzle output.
THE BURNER RUNS THE PREPURGING BUT DOES NOT IGNITE:
Check the position of the electrodes; check the ignition cable;
Check the ignition transformer;
Check the control box.
THE BURNERS IGNITES BUT SWITCHES TO LOCKOUT AFTER THE SAFETY TIME:
Check phase and neutral for a correct connection.
Check gas solenoid valve.
Check the position of ionisation probe and its connection.
Check the control box.
Check nozzles (clogged or worn).
The photoresistor does not detect the flame.
The filters are clogged. Light-oil pressure too low.
Combustion air’s flow rate too high related to nozzle output.
THE BURNERS IGNITES BUT SWITCHES TO LOCKOUT AFTER FEW MOMENTS:
Check gas governor and gas filter.
Check gas pressure through a manometer.
Check ionization value (min. 70 µA).
THE BURNER DOES NOT SWITCHES TO HIGH (OR 3RD) FLAME:
Manual selector switch in wrong position.
Faulty control box. High (3rd) flame solenoid valve’s coils faulty. High (3rd) flame’s nozzle clogged.
Air damper’s jacket faulty or wrongly adjusted.
