Priming the pump: Start the burner and await priming.
Should lock-out occur prior to arrival of the fuel, wait at least 20 seconds
before repeating the operation.
This solution, however, is less safe than the previous one, due to
possibility of leakage of the valve.
Should, however, the return line terminate over the fuel level,
a non return valve is essential.
The return line should terminate within the oil tank at the same level
as the suction line; in this case a non return valve is not required.
The pump suction should not exceed a maximum of 4 metres.
Beyond this limit gas is released from the oil.

The pump suction must not exceed 4 metres;
beyond this value the pump becomes noisy.
The return valve must terminate at the same level
as the foot valve, otherwise the pump may
become air locked.
