LIGHT OIL SUPPLY
The dimensions of the fuel lines (diameter/length) are related to the type of burner (with one or two lines, in
suction feed / gravity feed) and with the pump specifications.
The diagram indicates the maximum length L allowed in a suction feed line with regards to the difference in
height of the fuel tank and the internal diameter of the tube d, for an atmospheric pressure of 1013 mbar and
a vacuum of 0.45 bar, considering assembly with 4 elbows of a stop valve and a one-way valve.
SINGLE LINE FUEL SUPPLY
It is recommended whenever possible to avoid this option, which can create significant malfunctions in the
burner if the installation has not been performed in a perfect manner. However, if it is not possible to avoid this
choice, we advise: use a gravity feed burner only, modify the pump by removing the Allen-head screw inside,
discharge air from the upper parts of the fuel line and avoid air bubbles.
DOUBLE LINE FUEL SUPPLY
N.B.: if the tube length exceeds 60m., we advise the use of a fuel pump – d10/2, d12/2 for double flame
burners.
