WARNING:
It is necessary to install a filter on the fuel supply line.
The pump is designed to allow working with two pipes. In order to obtain one pipe working it
is necessary to unscrew the return plug (2), remove the by-pass screw (3) and then screw
again the plug (2), (see fig. 7).
Before starting the burner make sure that the return pipe-line is not clogged. An excessive
back pressure would cause the damage of the pump seal.
