    (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.

    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 pulsantions.
