PRIMING THE PUMP
In case of a gravity feed system, from the bottom of the oil-storage tank (see page 3), loosen the screw of the suc-
tion-gauge fixing point 3 (fig. 1), until the fuel flows out.
In the other two cases, remove the high voltage cable from the ignition transformer and release air from the pressure
gauge fixing point, by loosening the screw 4 (fig. 1) do not light on the photo-resistor, because lock-out immediately
will occur.
If, during these operations, the burner locks out, reset it and repeat the cycle as many times as necessary.
CAUTION!
Check, before starting the burner, that the return line to the oil-storage tank is not in any way obstructed.
Any obstruction would cause the breakage of the pump seals.
