NOTE
The weight of the rear part of the pumping assembly exerts flexure stress on the guides; you are advised
to hold the burner while it is being extracted so as not damage the flame disc and the said guides.
For long - head version.
Use the pin extensions supplied to move the burner back.

When the burner operates with only one nozzle, the pressurization conditions are improved and no prob-
lems arise. Minimal fuel capacity with one only nozzle: 25 kg/h - 285 kW.

LOOP SYSTEM (max loop system 3 bar)
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
For fuel oil with viscosity max. 7°E at 50°C.

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-
er level, the return pipe should arrive at the
same level as the suction pipe.
In this case the foot valve is not required.
For fuel oil with viscosity max. 7°E at 50°C.

3- Burner 7- Burner pump
4- Air damper for eliminating burner (coupled) 8- Pressure adjuster
For heavy oil with viscosity up to 50°E/50°C.
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.
