ELECTRICAL CONNECTIONSAll 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 burneras in fig. Protect burner supply line with safety fuses and any other devices required by safety standards obtaining in thecountry in question.

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 thatthe 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 desiredtemperature. 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.

START UP OF THE BURNERPRELIMINARY CHECKSBefore starting up the boiler check the following:• gas type and feed pressure;• gas valves closed;• the seals in the pipe fittings;• gas pipe breather and input pressure;• that the cable complies with the diagram and the phase and neutral wires correspond;• that the burner shuts down when the boiler thermostat opens• the seal of the boiler furnace which prevents air from entering• the seal on the flue-boiler pipe fitting;• the condition of the flue (sealed, free from blockage, etc.).If all these conditions are present, start the burner. The control device starts the motor to carry out prewashing of thecombustion chamber. During this prewash period (about 30 seconds) the device checks that air pressure is correct viathe air pressure switch. At the end, it supplies power to the transformer and opens the gas valves. The flame must be litand stabilize within 3 seconds, which is the device's safety time limit. Check to ensure the flame is lit before placing anycontrol instrument in the flue. Adjust and check the gas flow necessary for the boiler at the meter. Adjust the air flowaccording to the gas flow to obtain correct combustion.

IMPORTANT ADVICEAll adjustable parts must be fixed by the installer after making adjustments. Check flue combustion after each adjust-ment. The CO2 values must be approx. 9.7 (G20) 9.6 (G25 11.7 (l3B) 11.7 (l3P) and the CO must be less than 75ppm.

ADJUSTING THE COMBUSTION

L.P.G.

CO2 11,7 %CO < 50 ppm

Nat. gas

CO2 9,6 %CO < 50 ppm

WARNING: in order to adjust combustion and thermal capacity correctly, the fumes must be analyzed using specific instruments.Combustion and thermal capacity must be adjusted simultaneously, making sure that the values read are correct and in anycase, that they comply with the safety regulations in force.THIS OPERATION MUST BE PERFORMED BY PERSONNEL WHO ARE PROFESSIONALLY QUALIFIEDAND AUTHORIZED BY ECOFLAM SPA.

”PAB” VERSION GAS BURNERS GAS TRAIN INSTALLATION AND SETTING INSTRUCTIONSFix the gas train to burner body by means of the 4 screws of the flange, pay attention to set correctly the gasket ( O-ring ).Connect electrically the gas train with the 6 pole plug.Switch on the burner (it has already been tested in the factory, so it is pre set on average values) and verify the tightnessof gas train connections made during installation.Act as follows to adapt the burner output to the boiler.

HIGH FLAME1. Bring the burner in high flame , air inlet must be set at 75 ° (maximum opening position).To adjust air capacity operate on the combustion head position.Just in peculiar case it is necessary to reduce the air flow in high flame closing air intake damper.2. The position of gas butterfly valve must be lower then 90° ( typically 85°. It is important not get over 90° to obtaina perfect combustion during passage from high to low flame). Eventually adjust this position acting on the screw “1 “,after loosening nut “ 2 “.3. Regulate gas capacity in high flame through the gas governor, or operate on the adjustable gas valve.

LOW FLAME4. Choose the first stage position on the servocontrol ( normally between 10° - 30°) on the basis of the reduced chargeoutput required and switch the burner to low flame.5. Regulate gas capacity, to obtain optimal combustion, changing the position of the gas valve disc, act on screw “ 3 “,after loosen nut “ 4 “.

To calculate the burner’s working output, in kW, proceed as follows:

- Check at the meter the quantity of supplied litres and the duration, in seconds, of the reading, then calculate the burner’s output through the following formula:

CALCULATION OF WORKING OUTPUT OF THE BURNER

e x f = kWs

e = Litres of gass = Time in seconds

G20 = 34,02G25 = 29,25G30 = 116G31 = 88

MAINTENANCEYEARLY CHECKS:

The periodical checks of the burner (combustion head, electrodes etc.) must be carried out by authorised techni-cians once or twice in a year, according to burner’s duty conditions. Before going on with maintenance operations, it is advisable to proceed through a control of the burner’s generalstate as follows:- Unplug the burner from supply mains. - Close the gas cock. - Remove burner’s cover and clean fan and air intake’s duct. - Clean the combustion head and check electrodes position. - Reassemble the whole. - Check fittings seal.- Check the chimney. - Restart the burner and check combustion values (CO2 = 9,7% (G 20); 11,7% (G 30); 11,7% (G 31); CO lower than 75 ppm).

BEFORE ANY INTERVENTION VERIFY THAT:

- The system is supplied with power and the burner is plugged in. - Gas pressure is the correct one and the gas cock is open. - The control devices are suitably connected. - If all such a conditions are satisfied, start the burner by pressing the lockout rearm button and check its ignitionsequence.

SHORT TROUBLESHOOTING:

- The burner does not start: check power switch, thermostats, motor, gas pressure, leakage control device (if any).- The burner runs the pre-purging but switches to lockout at the end of cycle: check air pressure, fan and air

pressure switch.- The burner runs the pre-purging but does not ignite: check electrodes installation and position, ignition cable,

ignition transformer, control box and gas solenoid valves.- The burner ignites but switches to lockout at the expiring of safety time: check that phase and neutral are

properly connected; check ionization probe’s position and connection; check control box.- The burner ignites properly but switches to lockout after few minutes of working: check gas pressure governor

and filter, gas pressure, detection value ( 3 µA min.) and combustion values.
