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.

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.

 

Any obstruction may damage the sealing of the pump.
