Fuel oil connection
Enclosed diagrams provide required
pipe diameters.
There are two following possibilities:
Direct suction:
–
According to length L and suction or
load height H and chance mishaps ;
These lengths include the presence
of a quarter-turn hand-operated
valve, a check valve and four elbows.
Maximum negative pressure 0.4bar.
Transfer loop:
–
According to the type of facility,
booster pump characteristics will
have to meet several criteria, notably:
– hourly flow,
– fluid flow speed,
– maximum boosting pressure.
Preference should be given to this
type of installation, in order to obtain
long spray pump life.

In both cases, it is compulsory to fit a
0.5
120µm filter and quarter-turn
hand-operated valve on the suction or
1.0
booster (not supplied).

Important:
Suction:
· Totally fill suction pipe between
spray pump and tank down-pipe with
fuel oil.
Transfer loop:
· Fill, boost, drain and set pressure in
circuit at 2bar max. It is advisable to
install a pressure switch to limit
burner operation to boost pressure.
· Check for possible leaks.

Electrical connection
The electrical characteristics such as
voltage, frequency, power, are
mentioned on the identification plate.
Minimum conductor section: 1.5 mm²
Delayed-action minimum protection
device: 6.3 A
Refer to the wiring diagrams for the
electrical connections:
– diagram enclosed with the burner
– diagram screen printed on socket

It must be possible to isolate the
burner from the network using an
01/2005 - Art. Nr. 13 017 870A
isolator that connects all poles and
complies with the current applicable
standards. The burner and the heat
generator are interconnected by a
7-pole connector. The cables
connected to this connector must
have a diameter between 8.3 mm
and 11 mm.
Optional :
External connection :
of an alarm between S3 and N.
–
of one (or more) hour meter
–
between B4 and N to totals the
operating hours, and between B5
and N to count the operating hours
at nominal flow stage (for 2-stage
burners only).
