Oilbuner
Type Gulliver RG0.R
Warning:
In the event of maintenance made to the
nozzle-holder assembly, screw the nut (C)
as shown in the figure to the right.
Pump pressure:
The pump leaves the factory set at 12 bar.
To change it act on pump pressure adjust
screw (4, page 3).
Air damper adjustment:
Use the knob (7) to make adjustments after
slightly loosening the screw (8) and
swinging out the protective covering (9).
Once adjustments have been made, place
the protective covering (9) in its correct po-
sition and tighten the screw (8).
The figure shows adjustment of the air dam-
per to a flow rate of 2.1 kg/h (notch 2.6).
When burner shuts down the air damper
automatically closes to a max flue draw of
0.5 mbar. The burner is also fitted with an
electromagnedtic device (10) which pre-
vents any slamming of the air damper on
burner starting, even in the presence of
high boiler counter-pressure.

Adjustment
Note:
In the event that the electromagnetic dam-
per anti-slamming device (10) fails, the bur-
ner will not start as the device is connected
to the motor in series (see diagram page 8),
and as such takes on a role of safety device.
In the event of an anomaly, the burner may
even be started without the device as it is
connected to the circuit via special connec-
tors which allow it to be cut out. The male
and female connectors on the device wire
must be disconnected and the motor con-
nectors must beconnected between them.
When resorting to this temporary solution, it
is fundamental that an alternative adjust-
ment og the air damper is carried out.
