Page 9: Burner Adjustment
BURNER ADJUSTMENT Establish, on the basis of the output desired, and in accordance with the table and the diagram underneath: - the type of nozzle; - the pump pressure; - the combustion head setting. EXAMPLE The burner has to be matched with a boiler of 210 kW. Assuming an efficiency of 90%, we need to develop approximately 233 kW i.e. - Page 10 (3) The indicated outputs are drawn from the average statistical data of our tests. Real output may well vary by ± 5%. (4) The rear level of the control-shaft (7) (fig. 1) must line-up with the set-point number, indicated by the diagram. In the sketch on the right, the shaft is shown, in the position required by the example on page 7.
- Page 11 All burner controls are clearly indicated into the instruction. Only the air damper adjustment for the second flame, is determined at the place of installation, depending on the boiler pressure. ATTENTION At the first ignition, passing from the first to the second flame, the oil pressure decrease noticeably because of the filling of the second nozzle line - this decreasing can cause the burner shutdown, sometimes with strong pulsations.

PRIMING THE PUMP In case of a gravity feed system, from the bottom of the oil-storage tank (see page 3), loosen the screw of the suc- tion-gauge fixing point 3 (fig. 1), until the fuel flows out. In the other two cases, remove the high voltage cable from the ignition transformer and release air from the pressure gauge fixing point, by loosening the screw 4 (fig. -

OPERATING FAULT DIAGNOSTICS The control box has a self-diagnostic system, which easily allows identifying the operating faults (RED LED signal). ITo use this function, wait at least ten seconds from the safety lock out, and then press the reset button for a minimum of 3 sec- onds. - Page 16 RIELLO S.p.A.
