SETTINGS
G18 SP - PG25 SP
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..
PG30 TN
Before carry out the settings, start-up the light oil pump proceeding as follows:
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.
start up the burner, light the photoresistor after the solenoid valve opening and leak the air from the manometer gauge.\
Light oil 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
G18 SP - PG25 SP
