Do not invert the neutral with the phase in the electrical supply line. Any inversion would cause a lockout due to firing failure. The RL 190 burners have been type-approved for intermittent operation. This means they should compulsorily be stopped at least once every 24 hours to enable the control box to perform checks of its own start-up effi- ciency.

Hydraulic system Hydraulic system Fuel supply The loop circuit A loop circuit consists of a loop of piping departing from and re- turning to the tank with an auxiliary pump that circulates the fuel under pressure. A branch connection from the loop goes to feed the burner.
Hydraulic system Hydraulic connections The pumps are equipped with a by-pass that connects return line with suction line. The pumps are installed on the burner with the by-pass closed by screw 6) (Fig. 23 pag. 19). It is therefore necessary to connect both hoses to the pump. The pump will break down immediately if it is run with the return line closed and the by-pass screw inserted.
