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 provided to move the burner back.

When the burner operates with only one nozzle, the pressurization conditions are better and no problems
arise. Minimal flow rate with one only nozzle: 10 kg/h - 114 kW.

loosen the cap of the vacuometer fitting
(5, fig. 1) and wait for the fuel to flow out.

Not advised, to be used only in case of
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 light fuel oil with viscosity max. 7°E at 50°C.

1- Tank (properly heated for heavy oil) 5- Transfer pump
2- Filter (with resistor for oil > 7°E / 50°C) 6- Check Manometer
3- Burner 7- Burner pump
4- Air dampers to exclude the burner (coupled) 8- Pressure adjuster
For heavy oil with viscosity up to 20°E / 50°C.
Important note: to let the fuel flow properly all the pipes have to be properly sized, insulated and heated
(with elec. resistor or steam or hot water).
Warning: before to starting up the burner, make sure that there are obstructions in the pipes.
A
ny obstruction may damage the sealing of the pump.
