Choose pipe diameter in table, according to length
between tank and pump.
If suction corrected H exceeds 4m, have transfer pump
available (max. pressure 2 bars).

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 of
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,
0
–
maximum boosting pressure.
0,5
Preference should be given to this
type of installation, in order to

obtain long spray pump life.

Important
In both cases, it is compulsory to
fit a 120µm² filter and quarter-turn
hand-operated valve on the suction
or booster (not supplied).
Important:
Suction:
· Totally fill suction pipe between
spray pump and tank down-pipe with
fuel oil.
Transfer loop:
14/16
· Fill, boost, drain and set pressure in
83
circuit at 2bar max. It is advisable to
83
install a pressure switch to limit
83
burner operation to boost pressure.
83
· Check for possible leaks.
