Pump adjustment
fi
To adjust the fuel pressure, use the specific adjustment screw (E Fig. 5). Turning the screw clockwise
no
increases the pressure, turning it in the opposite direction decreases it.
Remember that information on adjusting the pump pressure can be found in the manual. To check if the pump
sv pressure is correct, connect the manometer to the pressure plug (D Fig. 5). The pressure must be adjusted by
qualified personnel. Incorrect adjustment may result in improper combustion.

The pump is connected to the motor shaft through a plastic pump joint, shown here on the side. This
component safeguards the motor operation if the pump were to seize. In this case, the stall torque would
lv
effectively increase along with the absorbed current and the pump joint, breaking, would avoid further
damage to the motor.

IMPORTANT: If the pump joint breaks, replace it
with an original spare part.
The solenoid valve is an electromagnetic device. It is integrated in the fuel
pump and its purpose is to intercept the flow of fuel going from the pump to
the nozzle. When the flame control appliance gives consent, the solenoid
valve is powered and therefore opens, allowing the fuel to reach the nozzle.
Otherwise, when the machine is turned off, the solenoid valve is no longer
powered and therefore closes, blocking the fuel flow and therefore
interrupting the flame. There are two solenoid valve models based on the
type of power supply.
