The setting of the combustion head depends exclusively on the
burner delivery in the 2nd stage - in other words, the combined
delivery of the two nozzles selected in table (Tab. A).
Turn screw 4) (Fig. 12) until the notch shown in diagram (Fig. 13)
is level with the front surface of flange 5) (Fig. 10, pag. 12).
Example:
The RL 190 Model with two 18 GPH nozzles and 12 bar pump
pressure.
Find the delivery of the two 18 GPH nozzles in (Tab. A, pag. 7):
76.4 + 76.4 = 152,8 kg/h.
Diagram (Fig. 13) indicates that for a delivery of 152,8 kg/h the
RL 190 Model requires the combustion head to be set to approx.
three notches, as shown in (Fig. 12).
