The light oil recovery tanks
(diameter ~ 150, height ~ 400) should be installed
as near as possible to the burner and should be
about 0,5 m. higher with respect to the burner’s
pump.

DESCRIPTION OF TWO STAGE PROGRESSIVE OPERATIONS WITH LIGHT OIL
(See BT 8714/2)
This is referred to as a 2-stage progressive operation because the passage from the 1
st
fl ame to the 2
nd
fl ame
(from the minimum rate to the maximum pre-established rate) takes place gradually both as delivery of combu-
stion air and of fuel.
The burner’s control box (cyclic relay) is connected by operating panel switch ( I ).

The cyclic relay control box carries out the ignition programme by starting up the fan motor and thus the pump
in order to effect the pre-ventilation and light oil pre-circulation phases.
It is necessary that the air pressure supplied by the fan is suffi cient to cause the intervention of the relative
pressure switch, if not, the control box will go to “shut down”.
Oil from the pump reaches the atomizer unit and circulates within it because the passages leading to the outward
and return nozzles are closed.
This closure is carried out by “closing pins” applied to the ends of the rods.
