SETTINGS
Burners G18SP - PG25SP
These burners are fitted with a double-regulation pump. The flame control device, a twin-stage one, after the pre-purgue stage,
energized the valve EV1 and the burner starts up.
After few seconds, the intervention of the second stage caused the energizing of the valve EV2, so the burner is feeded with a
maximum pressure of about 18 bar.
Burner PG30TN
Before carry out the settings, start-up the light oil pump proceeding as follows:
- start up the burner, light the photoresistor after the solenoid valve opening and leak the air from the manometer gauge.
Before starting up the burner, be sure that the return pipe to the tank is not obstructed; any obstruction would cause the pump
seal to break.
Light oil flow rate setting
The light oil rate is adjusted by chosing a nozzle with appropriate dimensions and setting the inlet pump pressure; to chose the
nozzle, refer to the tables below.
LIGHT OIL PUMP SETTINGS
Burners G18SP - PG25SP
Adjust the pump for the ingnition, to a pressure value of about 8-10 bar (see fig. 7).
After 10”, the safety device drives the second stage; set the pump to a pressure value of 18 bar, by means of the regulation screw.
Burner PG30TN
Set the pump to a pressure value from 10 to 14 bar, depending by the nozzle fitted (see table 2).
