CONNECTION TO THE GAS PIPELINEOnce 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 BURNEROnce connected the burner to the gas pipe make sure that there are no leakages. Air bleed the pipe through the pressuregauge fixing point and check the pressure with a pressure gauge . Turn the thermostats to the desired temperature. PRELIMINARY CHECKS - Before 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 thephase and neutral wires correspond; - that the burner shuts down when the boiler thermostat opens;- the seal of theboiler furnace which prevents air from entering; - the seal on the flue-boiler pipe fitting; - the condition of the flue (sea-led, free from blockage, etc ).If all these conditions are present, start the burner. The control device starts the motor tocarry out prewashing of the combustion chamber. During this prewash period (about 30 seconds) the device checksthat air pressure is correct via the air pressure switch. At the end, it supplies power to the transformer and opens the gasvalves. The flame must be lit and stabilize within 3 seconds, which is the device's safety time limit. Check to ensure theflame is lit before placing any control instrument in the flue. Adjust and check the gas flow necessary for the boiler atthe meter. Adjust the air flow according to the gas flow to obtain correct combustion.

ADJUSTING THE COMBUSTION PROCESSIMPORTANT: to obtain the right adjustment of the combustion and thermal capacity it is important to analyze thereducts of combustion with the aid of suitable instruments. The combustion and thermal capacity adjustment is donesimultaneously, together with the analysis of the products of combustion, making sure that the measured values are sui-table 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.

LANDIS LGB 22 UP-CYCLE

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

CALCULATING THE BURNER CAPACITYTo calculate the burner's capacity in kW, proceed as follows: Check the gas flow rate (in liters) onthe counter and the time of the reading in seconds.

Proceed with the calculation using the following : e x f = kWsec

e = Litres gassec = Time in secondG20 = 34,02G30 = 116G31 = 88

SELECTOR

ADJUSTING THE MINIMUM CAPACITY OF THE BURNER – AIR and GASPosition the selector placed on the control panel on position 2 and proceed as follows: Adjust the minimum gas flow rate using a suitable wrench, turn the butterfly valve until you reach the correct gas flow,as established by analyzing the combustion process.

ADJUSTING THE MAXIMUM CAPACITY OF THE GASPosition the selector, situated on the control panel, on position 1 and proceed as follows: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 ismade 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 ofthe 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 SWITCHUnscrew off and remove cover M. - Set regulator N to a value equal to 60% of gas nominal feedpressure (i.e. for nat. gas nom. pressure = 20 mbar, set regulator to a value of 12 mbar; forL.P.G. nom. pressure of G30/G31- 30/37 mbar, set regulator to a value of 18 mbar).Screwup cover M

DJUSTMENT OF THE AIR PRESSURE SWITCHUnscrew screws A and B and remove cover C.- Set the pressure switch to the minimum byturning regulator D to position 1. - Start the burner and keep in low flame running, while checking that combustion is correct.Through a small cardboard, progressively obstruct the air intake until to obtain a CO2 increaseof 0,5÷0,8% or else, if a pressure gauge is available, connected to pressure port E, until rea-ching a pressure drop of 1 mbar (10 mm of W.G.). - Slowly increase the adjustment valueof the air pressure switch until to have the burner lockout. Remove the obstruction fromthe air intake, screw on the cover C and start the burner by pressing the control box rearmbutton.

COMBUSTION ADJUSTMENT WARNING: In order to have a correct combustion and thermal output adjustments, these must be carried out togetherwith a combustion analysis, to be executed through suitable devices, taking care that the values are the correct ones andare in accordance with the local safety regulations. The adjustments must be carried out by qualified and skilled techni-cians authorised by Ecoflam Bruciatori S.p.A..

SETTING THE FIRING HEADThe firing head position adjustment is made in order to obtain the best combustion efficiency. When used with mini-mum outputs the firing head is adjusted in rear position. With high output, the firing head is adjusted in forward posi-tion. Adjustment: - Loosen screw A through a suitable Allen key.- By a screwdriver act on the hex. head screw B until isreached the desired position. - Tighten screw A

MAINTENANCEYEARLY INSPECTION Periodic inspection of the burner (combustion head, electrodes, etc.) must be carried out by authorised personnel onceor twice a year, depending of use. Before carrying out maintenance inspection on the burner, it is advisable to check its general condition and carry outthe following operations:- Disconnect the burner from the power supply (remove the plug). - Close the gas cock.- Remove the burner cover, clean the fan and air intake.- Clean the combustion head and check the position of the electrodes.- Re-assemble the parts.- Check the seal on the gas pipe fittings.- Check the flue.- Restart the burner.- Check the combustion parameters (CO2 = 9.5 to 9.8),(O = less than 75 ppm).

BEFORE EACH INTERVENTION CHECK:- That the system is supplied with power and the burner connected.- That the gas pressure is correct and the gas cock open. - That the control systems are correctly connected.If all these conditions are present, start the burner by pressing the release button. Check the burner cycle.

THE BURNER WILL NOT START:- Check the switch, thermostats, motor, gas pressure.

THE BURNER PREVENTILATES AND LOCKS AT THE END OF THE CYCLE:- Check the air pressure and fan.- Check the air pressure switch.

THE BURNER PREVENTILATES AND WILL NOT IGNITE:- Check the assembly and position of electrodes.- Check the ignition cable.- Check the ignition transformer.- Check the safety devices.

THE BURNER STARTS UP AND LOCKS AFTER THE SAFETY TIME LIMIT: - Check that the phase and neutral wires are correctly connected.- Check the gas electrovalves. - Check the position of the detection electrode and its connection.- Check the detection electrode.- Check the safety devices.

THE BURNER STARTS UP AND LOCKS AFTER RUNNING FOR A FEW MINUTES:- Check the pressure regulator and the gas filter.- Check the gas pressure with an ammeter.- Check the detection value (min 3 µA LGB22).

The minimum current necessary to operate the control-box is 3µA (Landis LGB22). When the measurement of the current isrequired it is necessary to disconnect the lead to the probe andinsert in its place a microammeter for direct current (see fig.under).
