Installation Installation Notes on safety for the installation After carefully cleaning all around the area where the burner will be The installation of the burner must be carried out by installed, and arranging the correct lighting of the environment, pro- qualified personnel, as indicated in this manual and ceed with the installation operations.
Installation Securing the burner to the boiler Detach the combustion head from the burner, (Fig. 11): install the extension bars 31)(Fig. 3, page 10) and re-screw disconnect the oil pipes by unscrewing the two connectors 6); the screws 2) including the safety plate 15); ...
The burner complies with the emission requirements of the UL 296 standard. In order to guarantee that emissions do not vary, recommended and/or alternative nozzles specified by Riello in the Instruction and warning booklet should be used. It is advisable to replace the nozzle once a year dur- ing periodical maintenance.
Installation 4.8.2 Adjusting the nozzle flow rate The nozzle flow rate varies according to the fuel pressure on the nozzle return. Diagram (Fig. 17) indicates this relationship for type A4 return flow nozzles with pump delivery pressure of 290 PSI. See Fig. 17: Horizontal axis: PSI, nozzle return pressure Vertical axis:...
Installation Combustion head setting The setting of the combustion head depends exclusively on the maximum delivery of the burner. Turn screw 6)(Fig. 18) until the notch shown in diagram (Fig. 19) is level with the front surface of flange 5)(Fig. 18). Example RLS 100/EV: maximum burner delivery = 23.1 GPH.
Installation 4.11 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 Insert the hose connections with the supplied seals into the con- 4.11.1 Hydraulic connections nections and screw them down. The pumps are equipped with a by-pass that separates return line Take care that the hoses are not stretched or twisted during instal- and suction line.
Installation 4.12 Gas feeding 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 4.12.2 Gas pressure RLS 70/EV D11955 The adjacent diagram is used to calculate manifold pressure taking into account combustion chamber pressure. Gas manifold pressure measured at test point 1)(Fig. 27), with: • combustion chamber at 0 ” WC •...
Installation 4.13 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 The connection from the Inverter to LMV36..must be done as It is very importatnt to shield the motor cable 1) as shown in Fig. 29. shown in Fig. 29. Key (Fig. 29) It is very importatnt to fix the cable shielding as Motor supply cable WARNING shown in Fig.
Installation 4.13.3 Inverter connection Treatment of cables Countermeasures against cable noise Following, it is reported an example how to con- nect the Inverter. The treatment of cables is the most important countermeasure. For further information, please refer to the relevant The machinery manufacturers are requested Inverter instruction manual.

Start-up, calibration and operation of the burner Burner start-up Feed electricity to the burner via the disconnecting switch on the boiler panel. Close the thermostats/pressure switches, set the parameters on the RWF 40 regulator. Please refer to the specific manual for this operation. Turn the switch to position “ON”...
Start-up, calibration and operation of the burner Final calibration of the pressure switches 5.7.1 Air pressure switch The air pressure switch (Fig. 47) is connected in differential 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 5.7.4 Low oil pressure switch The low oil pressure switch is factory set to 261 PSI (18 bar). If the oil pressure goes down this value in the delivery piping, the pres- sure switch stops the burner. Burner starts again automatically if the pressure goes above 261 PSI (18 bar) after burner start up.
Start-up, calibration and operation of the burner Flame signal measurement Check the flame signal through the parameter 954, as indicated in Fig. 52. 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.

Maintenance GAS OPERATION Check to make sure that no dust has accumulated inside the fan or on its blades, as this condition will cause a reduction in the air flow Gas leaks rate and provoke polluting combustion. Make sure that there are no gas leaks on the pipework between the gas meter and the burner.
Maintenance Opening the burner To open the burner proceed sa follows: loosen screws 1) and withdraw the cover 2); Disconnect the electrical supply from the burner by disengage the swivel coupling 7) from the graduated sector; means of the main system switch. ...
