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. Should, however, the return line
terminate over the fuel level, a non return
valve is essential. This solution, however, is
less safe than the previous one, due to the
possibility of leakage in the valve.
Priming the pump: start the burner and
await priming. Should lock-out prior to
arrival of the fuel, wait at least 20 seconds
before repeating the operation
