Pump

 The pump (Fig. 11) is suitable for two-pipe operation. For
single pipe operation it is necessary to loosen the return line
nut 2), remove the by-pass screw 3), then retighten the nut
2) (Fig. 11).
The closure plug of the oil supply (Suction line 1)
(Fig. 11) is plastic. Once removed, you must throw
it away and not re-use it under any circumstances.
WARNING
In one-pipe systems, the plug supplied on the re-
turn line 2) of the pump is steel.
IT IS VERY IMPORTANT that the steel plug
is used EXCLUSIVELY for this purpose.
 Before starting up the burner, make sure that the return
pipeline is not clogged.
An excessive back pressure ( 1 bar) would cause the dam-
age of the pump seal, with subsequent fuel leaks inside the
burner.
