Installation Nozzle The burner complies with the emission requirements of the UL 296 If it proves necessary to change a nozzle with the burner already Standard. fitted to the boiler, proceed as outlined below: pull back the burner on its slide bars as shown in Fig. 14 at In order to guarantee that emissions do not vary, recommended page 17.
Installation 4.9.4 Adjusting the nozzle flow rate The nozzle flow rate varies according to the fuel pressure on the The values indicated in the right side of the diagram nozzle return. (Fig. 19), refer to the data printed on the nozzle. WARNING Diagram (Fig.
Installation 4.10 Combustion head setting The setting of the combustion head depends exclusively on the maximum delivery of the burner. Turn screw 4)(Fig. 21) until the notch shown in diagram (Fig. 22) is level with the front surface of flange 5)(Fig. 21). Example: RL 190/E, maximum light oil delivery = 48 GPH Diagram (Fig.
Installation 4.12 Light oil supply Explosion danger due to fuel leaks in the presence of a flammable source. Precautions: avoid knocking, attrition, sparks and heat. Make sure 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 4.12.1 Hydraulic connections The pumps are equipped with a by-pass that separates return line with suction line (Fig. 25). The pumps are installed on the burner with the by-pass closed by screw 6)(Fig. 27 at page 23). It is therefore necessary to connect both hoses to the pump. The pump seal will be damaged immediately if it is run with the return line closed and the by-pass screw inserted.
Installation 4.13 Pump 4.13.1 Pump priming Before starting the burner, make sure that the tank return line is not clogged. Obstructions in the line could cause the seal located WARNING on the pump shaft to break. The time required for this operation depends upon the diameter and length of the suction tubing.
Installation 4.14 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 4.14.1 Supply cables and external connections passage All the cables to be connected to the burner are fed through the grommets. See Fig. 28. The use of the cable grommets can take various forms. By way of example we indicate the following mode (according to UL795): 1 Three phase power supply with 3/4 inch cable grommet 2 Available: single phase power supply and other devices with 1/2 inch cable grommet...

Installation 4.16 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- ent connection than IE1 motors no more star/delta WARNING 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. 39) 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. 41. 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- Before carrying out any maintenance, cleaning or checking opera- ty, yield and duration of the burner. tions: It allows you to reduce consumption and polluting emissions and to keep the product in a reliable state over time.
Maintenance Pump The pump delivery pressure must be stable at 290 PSI. The suction must be less than 6.5 PSI. Unusual noise must not be evident dur- ing pump operation. If the pressure is found to be unstable or if the pump runs noisily, the flexible hose must be detached from the line filter and the fuel must be sucked from a tank located near the burner.
Maintenance 6.2.4 Safety components The safety components must be replaced at the end of their life cycle indicated in Tab. M. The specified life cycles do not refer to the warranty terms indicated in the delivery or payment conditions. Safety component Life cycle 10 years or 250,000 Flame control...
