After having installed the nozzle, check the correct
position of the electrodes and disk according to the
following levels. It’s adviseable 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.

IGNITION AND ADJUSTMENT
Loosen the xing screw “6” (see 0002933240) 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 deector disk (adjustable
via screw 2, see 0002933230). The burner is, in fact, tted with a special screw to adjust the position of the deector
disk; this device allows for optimisation of combustion by reducing or increasing the air ow between deector disk
and head. It is normally necessary to reduce (undo screw 2) the air ow between deector disk and 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 deector disk it is, usually, necessary to
correct the air damper positions and afterwards check for proper ignition. BTL 0H-4H-6H-10H burners are equipped
with an on-nozzle light oil heater. This device provides better atomisation and thus better combustion.

N.B. Ignition can be improved under certain working conditions
by slightly adjusting the position of the electrodes.
