Installation Use the 4 screws provided after having protected the thread 4.6.1 Combustion head pre-setting (RL 130/E) with an anti-seize product. At this point check, whether the maximum delivery of the burner is contained in area B or in area C of the firing rate. See Fig. 5. If it is in area B then no operation is required.
Installation 4.7.3 Choice of nozzle slightly decrease the pressure in the return line until they are com- pletely eliminated. In case an intermediate delivery between the two values indicated in the diagrams (Fig. 17) is required, a nozzle with higher delivery must be chosen.
Installation Electrode adjustment Make sure that the electrodes are positioned as shown in Fig. 19. WARNING D2528 Fig. 19 Combustion head setting The setting of the combustion head depends exclusively on the maximum burner delivery at which it will be operating. Turn screw 4)(Fig.
Installation 4.10 Hydraulic system Explosion danger due to fuel leaks in the presence of a flammable source. Precautions: avoid knocking, attrition, sparks and heat. Make sure that the fuel interception tap is closed before performing any operation on the burner. The fuel supply line must be installed by qualified personnel, in compliance with current standards and laws.
Installation 4.10.2 Hydraulic connections The pumps are equipped with a by-pass that connects the return line and suction line. The pumps are installed on the burner with the by-pass closed by screw 6)(Fig. 24). It is therefore necessary to connect both hoses to the pump. The pump seal will be dammaged immediately if it is run with the return line closed and the by- pass screw inserted.
Installation 4.10.4 Pump Pump priming Before starting the burner, make sure that the tank Pump model SUNTEC J7 C return line is not clogged. Min. delivery rate at 290 PSI pressure 60.8 Obstructions in the line could cause the seal located Delivery pressure range 145 - 304.5 WARNING...
Installation 4.12 Electrical wiring Notes on safety for the electrical wiring The electrical wiring must be carried out with the electrical supply disconnected. Electrical wiring must be carried out by qualified personnel and in compliance with the regulations currently in force in the country of destination.

Installation 4.14 Motor connection at 208-230 or 460V Please, pay attention to the indications in case of modification of the motors, manufactured for 208-230/460 IE3 voltage, maintenance, or substitution. NEMA Premium Efficiency voltage, have the same connection than IE2/Epact motors, but differ- WARNING ent connection than IE1 motors no more star/delta but star/double star.
Start-up, calibration and operation of the burner Start-up, calibration and operation of the burner Notes on safety for the first start-up The first start-up of the burner must be carried out Check the correct working of the adjustment, com- by qualified personnel, as indicated in this manual mand and safety devices.
Start-up, calibration and operation of the burner Final calibration of the pressure switch 5.4.1 Air pressure switch The air pressure switch is connected in differential (Fig. 37) and is activated by both the negative pressure of the air intake and the air pressure from the fan.
Start-up, calibration and operation of the burner Flame signal measurement Check the flame signal through the parameter 954, as indicated in Fig. 39. The displayed value is expressed in percentage. The value during the operation must be higher than 24%. If at the burner start-up the value is higher or equal of 18%, the burner locks out due to the extraneous light.
Maintenance Maintenance Notes on safety for the maintenance The periodic maintenance is essential for the good operation, safe- ty, yield and duration of the burner. Disconnect the electrical supply from the burner by It allows you to reduce consumption and polluting emissions and to means of the main system switch.
6.2.3 Fuel pump and/or couplings replacement As per Fig. 43, dimension A should be set: Model A (inch) RL 70/E 2” RL 100/E (230/460V) 64” (575V) 32” RL 130/E 16” Tab. O D2854 Fig.
Maintenance Opening the burner Loosen screws 1)(Fig. 44) and withdraw the cover 2); unscrew screws 3); Disconnect the electrical supply from the burner by fit the two extensions 4) supplied with a kit on request onto the means of the main system switch.
