If suction corrected H exceeds 4m, have transfer
pump available (max. pressure 2 bars).

Fuel oil connection
Use the accompanying diagrams to
determine the inside diameter of the
pipes.
Two scenarios:
In direct suction:
–
in accordance with length (L), suction
or pressure head (H) and any
irregularities of the run;
Lengths take the presence of a ball
valve, a non-return valve and four
elbows into account.
Maximum pressure reduction: 0.4bar.
On 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.
This setup is preferable to ensure
that the atomization pump has a
long working life.
m
Important :
In both cases, a 120µm² filter and
= 3 m
ball valve (not supplied), suited to
= 1 m
use, are to be installed upstream of
the suction or boosting hose.
Important:
With suction:
· Completely fill suction hose with fuel
oil between atomization pump and
immersion pipe in tank.
On transfer loop:
14/16
· Fill, boost, vent and set pressure in
83
circuit at 2bar max.
83
You are advised to include a fuel oil
83
pressure switch so that burner
83
operation is controlled by the boost
83
pressure.

· Check for leaks.
