Start-up, calibration and operation of the burner
7.1 Notes on safety for the first start-up
7.2 Calibrations before firing
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. 24) in such way that its rear surface corre-
sponds to the notch number shown in diagram (Fig. 25).
Example:
The PRESS GBV Model with 5 GPH nozzle and 12 bar pump
pressure.
Find the delivery of the 5 GPH nozzle in (Tab. F on page 17) =
21.2 kg/h.
Diagram (Fig. 25) 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. 26).
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.
7.2.3 Fan gate adjustment
The fan gate is set using the indexed selector 1)(Fig. 27), after
having loosened the nut 2).
This setting must be adapted case by case to the burner's deliv-
ery and combustion chamber pressure.
The first time the burner is fired, this setting should be left as orig-
inally set by the manufacturer: notch 2.
In summary, the operations and settings that must be performed
prior to firing the burner for the first time are as follows:
• choice of the nozzle;
• setting of the combustion head;
The following require no adjustment operations and may remain
as they are provided:
• pump pressure;
• setting of the fan's air gate valve.
