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 verifythat the chimney is not obstructed. Open the gas cock and carefully bleed the piping through the pressure gaugeconnector, then check the pressure value trough a suitable gauge. Power on the system and adjust the thermostats tothe desired temperature. When thermostats close, the sealing control device runs a seal test of valves; at the end ofthe test the burner will be enabled to run the start-up sequence.

ELECTRICAL CONNECTIONSAll burners factory tested at 400 V 50 Hz three-phase for motors and 230 V 50 Hz monophase with neutral forauxiliary equipment. If mains supply is 230 V 50 Hz threephase withuot neutral, change position of connectors onburner as in fig. Protect burner supply line with safety fuses and any other devices required by safety standards obtai-ning in the country in question.

BURNER START-UPBefore starting the burner, make sure it is mounted correctly. Then check connections are correct according to thediagram and piping is appropriate to the system. Before connecting the burner to the electricity supply, make surevoltage corresponds to burner plate data. The connection diagram and start-up cycle are shown separately. Forwiring from control box to burner, see the enclosed connection diagram. Pay particular attention to neutral andphase connections : never exchange them!. Vent air and impurities of gas pipe. Check gas pressure conforms to thelimits stated on the burner plate when connecting a master gauge to the test port provided on the burner. Blowermotor 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 bythe 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 ofthe prepurging time, the air servocontrol gets to the Low Flame position so that burnerignition is ensured at min. output. Simultaneously the ignition transformer receives voltageand after 3 seconds (pre-ignition) opens the pilot gas valve. Fuel flows to the combustion head and ignites. Twoseconds 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 gasfiring butterfly valve.Now the burner is operating at the min. firing rate (about 30% of the max. firing rate). The airservocontrol runs at the Low Flame position and in case the temperature control has to be set at the max. output itgoes to a fully open position of air damper and butterfly valve. During the burner-off periods the air damper closesup fully.

ADJUSTING THE COMBUSTION PROCESSIMPORTANT: to obtain the right adjustment of the combustion and thermal capacity it is important to analyzethe reducts of combustion with the aid of suitable instruments. The combustion and thermal capacity adjustment isdone simultaneously, together with the analysis of the products of combustion, making sure that the measuredvalues are suitable and that they comply with current safety standards. On this matter, please refer to the table andfigure below.THESE OPERATIONS MUST BE DONE BY PROFESSIONALLY-QUALIFIED TECHNICIANS.

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

CALCULATING THE BURNER CAPACITYTo 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 = kWe

The control box starts the burnerfan, to carry out the prepurging ofthe combustion chamber, andcheks the vent air pressure throughthe air pressure switch. At the endof prepurging, the ignition tran-sformer cuts-in and generates aspark between the electrodes. Atthe same time the two gas valvesopen (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 gaslack or a major pressure drop, the minimum air pressure switch shuts down the burner.

The ionization current is checked by inserting a microam-meter with an end of scale of 50 µA (d.c.) in series withthe ionization probe. A faulty position of the electrodecan lead to a reduction in the ionization current and causea safety cut-out of the burner due to a flame detection fai-lure. In this case, check the position of the electrode, itselectric connection and the earthing of the burner. Theionization current is normally > 20 µA.

OIL DELIVERY ADJUSTMENTThe diagram illustrates the fuel feeding system of these types of burners, which incorpora-tes a by-pass nozzle with oil flow regulation on its return pipe. The oil supply isvaried by acting on the nozzle through the pressure in the return line. Max. oil supplyis therefore reached when the pressure in the pump line is about 22 bar and the returnline is fully closed; min. oil supply when the return line is fully open. Relevant pres-sure readings in the return line are as follows:

Pump pressure 22-25 bar.Max Burner output, return oil pressure:FLUIDICS nozzle : 16 ÷19 bar.BERGONZO nozzle : 20 ÷24 bar.

Min Burner output, return oil pressure:FLUIDICS nozzle : 6 ÷9 barBERGONZO nozzle : 4 ÷8 bar

OPERATION OF BURNER WITH LIGHT-OIL FUEL Once having 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, whichwill run a prepurging of the combustion chamber for about 20 sec.At the end of prepurging, the control box opens solenoid valves and the burner starts. After a safety interval of 5seconds and a correct ignition, the control box turns off the ignition transformer and, 10 seconds later, sets themotorised air damper to its maximum opening (High flame). In case of faulty ignition, the control box switches theburner into safety condition within 5 second. In such a case, the manual rearming of the burner shall not take placebefore 30 seconds have elapsed from the burner’s safety shutdown. In order to obtain an optimal combustion, it isnecessary adjust the LOW - HIGH flame air flow, according to the instruction given further on. During such aphase, it will be possible to manually switch between HIGH and LOW flame and viceversa, through the High/Lowflame switch. At the end of the adjusting phase, leave the switch in position AUTO.

VERIFY:- That piping system is perfectly sealed;- That the use of hoses is avoided whenever is possible (use copperpipes preferably);- That depression is not greater than 0,45 bar, to avoid pump’scavitation;- That check valve is suitably designed for the duty;

The pump pressure is set at a value of 22-25 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 pri-ming. Start the burner and check the pump feeding pressure. In case the pump priming does not takeplace during the first prepurging, with a consequent, subsequent lock-out of the burner, rearm the burner’slock-out to restart, by pushing the button on the control box. If, after a successful pump priming, the bur-ner locks-out after the prepurging, due to a fuel pressure drop in the pump, rearm the burner’s lock-out torestart the burner. Do never allow the pump working without oil for more than three minutes. Note: befo-re starting the burner, check that the return pipe is open. An eventual obstruction could damage the pumpsealing device.

- Situation - The number 1999 blinks in the display as the actual value, with the set point value displayed normally.

- Cause - The real value is not being measured. This means that the upper or lowerlimit of the measurement range on analog input 1 (real value) has been exceeded.

- Remedy - Check the electrical connections and the state of the probe. If the probeis faulty, the regulator will not indicate the real value of the physical quantity monitored. This will result in automatic shutdown (failsafe), deactivation of theself-adapt function and inhibition of manual operation. The response of the auxiliary contact will depend on the configuration of parameter C113.

- Situation - The number 1999 blinks in the display as the actual value, with tAshowing in the set point field.

- Cause - The external temperature is not being measured. This means that theupper or lower limit of the measurement range on analog input 3 (real value) hasbeen exceeded.

- Remedy - Check the electrical connections and the state of the probe. If the probeis faulty, the regulator will not indicate the real value.

- Situation - The number 1999 blinks in the display as the actual value, with SP .Eshowing in the set point field.

- Cause - The external set point value is not being measured. This means that theupper or lower limit of the measurement range on analog input 2 (real value) hasbeen exceeded.

- Remedy - Check the electrical connections and the external set point signal. If theprobe is faulty, the regulator will not indicate the real value of the physical quantitymonitored. This will result in automatic shutdown (failsafe), deactivation of the self-adapt function and inhibition of manual operation.
