FUEL OIL SUPPLY SYSTEMS
GRAVITY SYSTEM
For fuel oil with viscosity max. 7°E at 50°C.
SUCTION SYSTEM
For fuel oil with viscosity max. 7°E at 50°C.
LOOP SYSTEM (max loop system 3 bar)
For heavy oil with viscosity up to 50°E/50°C.
1 - Tank (properly heated for heavy oil)
2 - Filter (with resistor for oil > 7°E / 50°C)
3 - Burner
4 - Air damper for eliminating burner (coupled)
Important note: to let the fuel flow properly all the pipes have to be properly sized, insulated and heated
(elec. resistor or steam or hot water).
Warning: before starting up the burner verify that there is no obstruction in the pipes.
any obstruction may damage the sealing of the pump.

Pump priming:
loosen the cap of the vacuometer fitting
(5, fig. 1) and wait for the fuel flow.
H: Difference in height
L: Length of the suction tube
D2727
Not advised, to be used only when
there is a previously existing system.
Never exceed the max. vacuum of 0.5 bar
(38 cm Hg) measured at the vacuometer
fitting (5, fig. 1 ).
The pipes should be perfectly airtight.
When the tank is placed below of the burn-
D2728
er level, the return pipe should arrive at the
same level as the suction pipe.
In this case the foot valve is not required.
5 - Transfer pump
6 - Manometer
7 - Burner pump
8 - Pressure adjuster
