Checking and setting the
combustion components
The nozzles are fitted on delivery.
· Withdraw cell from its seating.
· Disconnect the ignition cables from
the transformer and the oil tube.
· Unscrew (by two rotations) the three
screws from the cover.
· Turn (bayonet system) to withdraw
combustion components.
· Check the ignition electrode settings.
· Adjust and fit the nozzle in
accordance with the boiler power.
D E
· Reassemble.

· Check subsequently for leaks.

Secondary air
This is the flow of air admitted between
the turbulator diameter and the blast tube.
The position of the turbulator
(dimension Y) can be read from the
scale graduated from 0 to 35mm.
Maximum secondary air is indicated by
the 35 mark and minimum secondary
air by 0.
It can be adjusted according to:
ignition quality (shock, vibration,
–
chatter, delay),
combustion efficiency.

Should the blast tube be taken off:
· Upon reassembly, check that fuel
discharge hole is in the lower
vertical position during shut-down.
Setting
This is done without disassembling the
burner (while in operation or when
stopped), in accordance with the values
shown in the accompanying table.
If dimension Y is reduced, CO
increases, and conversely.
· Turn screw A in the direction desired.
