If the pump is operated with the return closed

and the bypass screw inserted, it will be damaged immediately.

The burner leaves the factory with the internal pump bypass
closed, that is, the burner is fitted for two-pipe connection.
Remove the caps and connect the two flexible pipes to the
pump inlet (1) and return (2), as shown in Figure 4, making
sure the flexible pipes are not twisted and that they are
positioned so that they will not be stepped on or come into
contact with the hot parts of the boiler.

If the internal pump bypass needs to be used for single-pipe
connections, remove the bypass screw (10) and cap the
return fitting (2) on the pump, connecting only the flexible 9
pipe to the inlet fitting (1).
