Air Damper Servomotor Adjustment; Positioning The Probe - Electrode - Riello RS5D Instrucciones De Instalación, Uso Y Mantenimiento

In (Fig. 12) the head is adjusted to an output of about 230 kW.
The notch 4 of the regulating rod lines up with the outer surface
of the head assembly as shown in the diagram.
Example:
The burner is installed in a 210 kW boiler.
Considering an efficiency of 90% the burner should deliver about
230 kW.
The diagram shows that for this output the adjustment must be
made on notch 4.
NOTE:
The diagram is for indication purposes; to ensure the burner works
at peak performance we suggest adjusting the combustion head
according to the requirements requested by the type of boiler.

Positioning the probe - electrode

 Make sure that the plate 3)(Fig. 14) is always inserted in the
flattening of the electrode 1)(Fig. 14).
 Rest the probe insulator 4)(Fig. 14) against the air diffuser
2)(Fig. 14).

Air damper servomotor adjustment

First stage - CAM I
Cam I (Fig. 13) adjusts, using the micrometric screw, the position
of the 1st stage damper (factory calibration reference value 25°).
Second stage - CAM II and CAM III
Cam II (Fig. 13) adjusts the position of the 2nd stage damper (fac-
tory calibration reference value 50°, do not exceed 65°).
Cam III (Fig. 13) commands the opening of the 2nd stage valve
(factory calibration reference value 35°).
Cam II should always be anticipated by at least 15°.
CAM V
Cam V (Fig. 13) is positioned in the factory (factory calibration ref-
erence value 90°).
Do not tamper with this adjustment for any reason.
