7.2.1
Combustion head setting
The setting of the combustion head depends exclusively on the
delivery of the burner - in other words, the delivery of the nozzle
selected on Tab. F at page 17.
Set the screw 1)(Fig. 30) in such way that its rear surface corre-
sponds to the notch number shown in diagram (Fig. 31).
Example:
The PRESS 1G Model with 3.00 GPH nozzle and 12 bar pump
pressure.
Find the delivery of the two 3.00 GPH nozzles in (Tab. F on
page 17):
12.7 + 12.7 = 25.4 kg/h.
Diagram (Fig. 31) indicates that for a delivery of 25.4 kg/h the
burner requires the combustion head to be set to approx. three
notches, as shown in (Fig. 32).
7.2.2
Pump adjustment
No presetting are required for the pump, which is set to 12 bar by
the manufacturer. This pressure must be checked and adjusted
(if required) after the burner has been ignited.
The only operation required in this phase is the application of a
pressure gauge on the apposite pump attachment indicated in
Tab. F at page 17.
