Page 5: General Features
PART I: INSTALLATION MANUAL GENERAL FEATURES This series of industrial burners is designed for all those applications that require big-sized air fans or air-flue heat exchangers to be installed in sound-proof areas to reduce noise. They can be provided with built-in or separately-mounted control panel (console or wall- mounted. -

Page 10: Fan Installation
Keys Burner Fixing nut Washer Ceramic fibre plait Stud bolt Blast tube Fig. 3 Fan installation Pay attention when designing the air duct: dimensioning must be performed according to the flow rate, the temperature, the distance between the fan and the burner and according to the fan features as well. ATTENTION! The bellows unit provided is made of canvas and is provided with blocking spacers to avoid breaking it during installation: first place the bellows unit between flanges, then remove the spacers. - Page 11 Matching the burner to the boiler The burners described in this manual have been tested with combustion chambers that comply with EN676 regulation and whose dimensions are described in the diagram . In case the burner must be coupled with boilers with a combustion chamber smaller in dia- meter or shorter than those described in the diagram, please contact the supplier, to verify that a correct matching is possible, with respect of the application involved.
- Page 12 Oil circuit The fuel is pushed into the pump 1 to the nozzle 3 at the delivery pressure set by the pressure governor. The solenoid valve 2 stops the fuel immission into the combustion chamber. The fuel flow rate that is not burnt goes back to the tank through the return circuit. The spill-back nozzle is feeded at constant pressure, while the return line pressure is adjusted by means of the pressure governor controlled by an actuator coupled to an adjusting cam.

Installation diagram of light oil pipes PLEASE READ CAREFULLY THE “WARNINGS” CHAPTER AT THE BEGINNING OF THIS MANUAL. From tank To tank Fig. 11 - Double-pipe system The burner is supplied with filter and flexible hoses, all the parts upstream the filter and downstream the return flexible hose, must be installed by the customer. - Page 15 Bleed Bleeding in two-pipe operation is automatic : it is assured by a bleed flat on the piston. In one-pipe operation, the plug of a pressure gauge port must be loosened until the air is evacuated from the system. Suntec T.. Viscosity 3 - 75 cSt Oil temperature...
- Page 16 Connecting the burner to the oil pumping unit Suntec T+TV Follow the scheme in the picture below to connect the burner to the oil pumping unit. The pump sends the oil coming from the tank to the burner. The pressure governor makes the oil reach the nozzle at the required pressure, while the excess of oil goes back to the tank.
- Page 17 Electrical connections RESPECT THE BASIC SAFETY RULES. MAKE SURE OF THE CONNECTION TO THE EARTHING SYSTEM. DO NOT REVERSE THE PHASE AND NEUTRAL CONNECTIONS. FIT A DIFFERENTIAL THERMAL MAGNET SWITCH ADE- QUATE FOR CONNECTION TO THE MAINS. STRICTLY OBSERVE THE DATA PLATE. As far as electrical connections, see the “ELECTRICAL WIRING DIAGRAMS”...
- Page 18 ADJUSTING AIR AND LIGHT OIL FLOW RATE The light oil flow rate can be adjusted choosing a by-pass nozzle that suits the boiler/utilisation output and setting the delivery and return pressure values according to the ones quoted on the chart below and the following diagrams (as far as reading the pressure values, see next paragraphs).

- Page 22 ADJUSTMENTS ATTENTION: before starting the burner up, be sure that the manual cutoff valves are open and check that the pres- sure upstream the gas train complies the value quoted on paragraph “Technical specifications”. Be sure that the mains switch is closed. Before starting up the burner, make sure that the return pipe to the tank is not obstructed.

Page 23: Adjustment Procedure
Adjustment procedure Check the fan motor rotation (see page 17). With the electrical panel open, prime the oil pump acting directly on the related CP contactor (see next picture): check the pump motor rotation and keep pressed for some seconds until the oil circuit is charged; bleed the air from the M pressure gauge port (Fig. - Page 24 (see Fig. 17 and page 15) as to get the nozzle pressure at 25bar (Fluidics/bergonzo nozzles - see diagram on page 22). Pressure gauge port Fig. 18 Fig. 19 In order to get the maximum oil flow rate, adjust the pressure (reading its value on the PG pressure gauge): always checking the combustion parameters, the adjustment is to be performed by means of the SV adjusting cam screw (see picture above) when the cam has reached the high flame position.
- Page 25 Calibration of air pressure switch To calibrate the air pressure switch, proceed as follows: Remove the transparent plastic cap. Once air and fuel setting have been accomplished, startup the burner. During the pre-purge phase o the operation, turn slowly the adjusting ring nut VR in the clockwise direction (to increase the adju- sting pressure) until the burner lockout, then read the value on the pressure switch scale and set it to a value reduced by 15%.
- Page 26 Fully modulating burners To adjust the fully-modulating burners, use the CMF switch on the burner control panel (see next picture), instead of the TAB thermo- stat as described on the previous paragraphs about the progressive burners. Go on adjusting the burner as described before, paying attention to use the CMF switch intead of TAB.

Page 27: Limitations Of Use
PART II: OPERATION LIMITATIONS OF USE THE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEING CORRECTLY CONNEC- TED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE, ETC.), ANY OTHER USE IS TO BE CONSIDE- RED IMPROPER AND THEREFORE DANGEROUS. -
Page 28: Routine Maintenance
PART III: MAINTENANCE At least once a year carry out the maintenance operations listed below. In the case of seasonal servicing, it is recommended to carry out the maintenance at the end of each heating season; in the case of continuous operation the maintenance is carried out every 6 months. - Page 29 Light oil filter maintenance For correct and proper servicing, proceed as follows: shut off fuel in the line section being serviced; unscrew the tray; remove the filter cartridge from its support and wash it with petrol or replace if necessary; check seal O-Ring, replace if necessary; reassemble the tray and restore fuel flow.
- Page 30 Electrode position setting ATTENTION: avoid the ignition electrode to contact metallic parts (blast tube, head, etc.), otherwise the boiler’s operation would be compromised. Check the electrode position after any intervention on the combustion head. To guarantee a good ignition, the masures below (in mm) must be observed (Fig. 24). A= 8 mm B= 3 mm C= 8 mm...
- Page 31 Checking the detection current To measure the detection signal follow the diagram in Fig. 25. If the signal is not in the advised range, check the electrical contacts, the cleaning of the combustion head, the position of the photore- sistor and if necessary replace it.
