Combustion head adjustment
The setting of the combustion head depends exclusively on the
delivery of the burner - in other words, the combined delivery of
the two nozzles selected on page 14.
Set the screw 1)(Fig. 15) in such way that its rear surface corre-
sponds to the notch number shown in diagram (Fig. 14).
Example:
The burner with two 5.00 GPH nozzles and 12 bar pump pres-
sure.
Find the delivery of the 5.00 GPH nozzle in Tab. I on page 15 =
21.2 kg/h.
Diagram (Fig. 14) indicates that for a delivery of 21.2 kg/h the
burner requires the combustion head to be set to approx.
3.1 notches, as shown in Fig. 16.

ery and combustion chamber pressure.

inally set by the manufacturer: notch 2.
