IGNITION AND ADJUSTMENT
Loosen the fixing screw “6” and bring the air damper into the position thought to be necessary as a function of the
quantity of fuel to be burnt. Turn the main switch to ON to power the burner and thus ignite it. Correct, if necessary,
combustion air delivery by acting on the intake damper and the position of the deflector disk (adjustable via screw 2).
The burner is, in fact, fitted with a special screw to adjust the position of the deflector disk; this device allows for
optimisation of combustion by reducing or increasing the air flow between the deflector disk and the head. It is
normally necessary to reduce (undo screw 2) the air flow between the deflector disk and the head when there is
reduced fuel delivery: this passage must be proportionately more open (screw in screw 2) when the burner is
working with a higher fuel delivery rate. After modifying the position of the deflector disk it is, usually, necessary to
correct the air damper positions and afterwards check for proper ignition. The burner is equipped with an on-nozzle
light oil heater. This device provides better atomisation and thus better combustion.
After having installed the nozzle, check the
correct position of the electrodes and disk
according to the following levels. It's
advisable to check levels after every
intervention on head.
N.B. To prevent damage to the support or
the pre-heater effect nozzle assembly/
disassembly tasks with the aid of a wrench
and counter-wrench.

The DSV.2 pre-heater gives efficient pre-heating of the light
oil and therefore ensures good ignition and stable, safe
operation even at low ambient temperatures. It is provided
with an incorporated solenoid cut-off valve and an anti-
dripping device which is used for hydrocarbon (CxHy)
during both ignition and burner shutdown.
