Installation Installation Notes on safety for the installation After carefully cleaning all around the area where the burner will The installation of the burner must be carried out by be installed, and arranging the correct lighting of the environ- qualified personnel, as indicated in this manual and ment, proceed with the installation operations.
Installation Burner raising In order to lift the burner, proceed as follows: The manufacturer declines any and every respon- screw the two extension bars 1) on the pins 2) (Fig. 10); sibility for any possible lifting movements, different place the two plates 3) fix them on the relevant ring nuts 4); from those indicated in this manual.
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 nozzles every year dur- ing regular maintenance operations.
Installation 4.8.3 Adjusting the nozzle flow rate The nozzle flow rate varies according to the fuel pressure on the nozzle return. Diagram (Fig. 16) indicates this relationship for type A4 return flow nozzles with pump delivery pressure of 290 PSI. See Fig. 16: Horizontal axis: PSI, nozzle return pressure Vertical axis:...

Start-up, calibration and operation of the burner Adjustments before first firing (gas operation) Ensure that the gas supply company has carried out the sup- ply line vent operations, eliminating air or inert gases from the piping. Slowly open the manual valves situated upstream of the gas train.
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 5.5.1 Air pressure switch The air pressure switch is connected in differential (Fig. 44) 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 5.5.3 Minimum gas pressure switch Adjust the minimum gas pressure switch (Fig. 46) after having per- formed all the other burner adjustments with the pressure switch set at the start of the scale. With the burner operating at MAX output, increase adjustment pressure by slowly turning the relative dial clockwise until the burn- er locks out.
Start-up, calibration and operation of the burner Burner starting (fuel oil adjustment Operating control closes, the motor starts. The pump 3)(Fig. 48) draws the fuel from the tank through the piping 1) and pumps it under pressure for delivery. The piston 4) rises and the fuel returns to the tank through the piping 5) - 7).
Start-up, calibration and operation of the burner Flame signal measurement Check the flame signal through the parameter 954, as indicated in Fig. 49. 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, Combustion head safety, yield and duration of the burner. Open the burner and make sure that all components of the com- It allows you to reduce consumption and polluting emissions and bustion head are in good condition, not deformed by the high tem- to keep the product in a reliable state over time.
