In particular, with single-tube systems, if the fuel inlet pipe is initially empty, the air contained
in the pipe must be vented for the fuel pump to be primed. It is recommended, before igniting
the burner, to loosen the pressure gauge connection screw on the pump and then perform the
ignition cycle.
When the oil comes out of the screw, the pump is primed. Switch off the burner and tighten the
screw.
