The static suction head will be the distance between the non-return valve and the burner s pump axle. The depression must not be greater than 0.5 bar; should it be higher, some damages could occur to the pump, with consequent increase in mechanical noises and,eventually, a failure. pag.9

A - INLET - RETURN - LEED AND PRESSURE GAUGE PORT - VAUUM GAUGE PORT 5 - PRESSURE ADJUSTMT 6 - TO NOZZLE 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 0,5 bar, to avoid pump s cavitation; - That check valve is suitably designed for the duty; The pump pressure is set at a value of bar during the testing of burners. efore 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 feeding 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. URNER START-UP AND ADJUSTMT 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, which will run a prepurging of the combustion chamber for about 6 sec. At the end of prepurging, the control box opens the fuel pump and the st stage (Low flame) solenoid valves, the ignition transformer produces a spark and the burner ignites. After a safety interval of 5 seconds and a correct ignition, the control box turns off the ignition transformer and, 5 seconds later, sets the motorised air damper to its maximum opening and opens the nd stage solenoid valve (High flame). In case of faulty ignition, the control box switches the burner into safety condition. In order to obtain an optimal combustion, it is necessary adjust the LOW - HIGH flame air flow, according to the instruction given further on. During such a phase, it will be possible to manually switch between HIGH ( II ) and LOW ( I ) flame and viceversa, through the High/Low flame switch. At the end of the adjusting phase, leave the switch in position II (HIGH flame). The fuel pump feeding pressure, must remain around bar. II I - st Stage. II - nd Stage (with an eventual Low/High automatic switching through a further thermostat connected to the terminal board, as shown by the scheme). I pag.

Proceed as follows: with the burner in lockout mode (red LED switched on) keep pressed the lockout button for more than sec. then release it. The red LED will blink according to the following error code list: Error ode Possible cause blinks No establishment of flame at the end of «TSA» - Faulty or soiled fuel valves - Faulty or soiled flame detector - Poor adjustment of burner, no fuel - Faulty ignition blinks Free blinks Extraneous light on burner start-up 5 blinks Free 6 blinks Free 7 blinks Too many losses of flame during operation (limitation of the number of repetitions) - Faulty or soiled fuel valves - Faulty or soiled flame detector - Poor adjustment of burner 8 blinks Time supervision oil pre-heater 9 blinks Free 0 blinks Wiring error or internal error, output contacts FIRING HEAD SETTING OMUSTION AIR FLOW ADJUSTMT (HIGH-LOW FLAME) + Air flow rate adjustment in Low flame running: ) - Start the burner (checking that the air damper is partially open). ) - Loosen clamping screw D. ) - Turn air damper until obtaining a correct combustion (checked with a combustion gas analysis set). ) - Tighten clamping screw D. Air flow rate adjustment in High flame running: WARNING: due to the presence of oil under pressure in the hydraulic jack when the burner is working in High flame condition, the air flow rate adjustment is to be made with the use of an adjusting ring nut with the burner running in Low flame condition. The combustion checks are to be done once the burner is turned to High flame condition D again. ) - Loosen clamping ring nut ) - Increase or decrease the air flow rate through the adjusting ring nut (lockwise to increase, counterclockwise to decrease). ) - Tighten clamping ring nut. ) - Switch manually from Low flame to High flame and check the combustion values. pag.

7 ELETRIAL ONNETIONS Maior P 50./00. A All burners are factory tested at 00V - 50Hz -phase for motors, and 0V - 50Hz single phase with neutral for auxiliary equipments. Should it be necessary to power the burner with 0V - 50Hz, modify the connections on motor and the terminal board as shown in the picture. Protect the burner supply line with suitable fuses and/or other safety devices as required by the local regulations on the matter. TROULESHOOTING The burner does not start. - Main switch in 0. - Fuses are blown. - oiler thermostats are in open position. - ontrol box is defective. The burner runs the prepurging but does not ignite and then switches into safety condition. - ontrol box is defective. - Ignition transformer is defective. - Electrodes are dirty. - Electrodes are defective. - Electrodes are in wrong position. - Nozzles are clogged. - Nozzles are too worn. - Filters are clogged. - Oil pressure too low. - ombustion air flow rate excessively high related to nozzle s flow rate. The burner ignites but then switches into safety condition. - ontrol box is defective. - Nozzles are clogged. - Nozzles are too worn. - The photocell does not detect the flame. - Filters are clogged. - Oil pressure too low. - ombustion air flow rate excessively high related to nozzle s flow rate. The burner does not switch to High flame. - st(low flame) and nd (High flame) stage manual switch on control board is in wrong position. - ontrol box is defective. - nd stage solenoid valve coil is defective. - Oil pressure too low. - Filters are clogged. - nd stage nozzle is too worn. - nd stage nozzle is clogged. - Air damper s hydraulic jack not properly adjusted or defective. pag.
