IGNITION AND ADJUSTMENT

Loosen the fixing 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 deflector disk (adjustable
via screw 2, see 0002933230). 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 deflector disk
and head. It is normally necessary to reduce (undo screw 2) the air flow between deflector 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 deflector 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.

The DSV.2 pre-heater (fitted as standard on the "BTL OH
- 4H" versions) gives efficacious 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)
abatement during both ignition and burner shutdown.

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.
