5.3 Pressure switch for min. oil

pressure

The burner control unit has a connection for a pressure switch for min. oil
pressure. If the facility regulations do not require this switch, a jumper should
be fitted between terminals 12 and 13 of the terminal block to close the
circuit and enable the burner to be started.

5.4 Pressure switch for max. oil

pressure

The burner control unit has a connection for a pressure switch for max. oil
pressure. If the facility regulations do not require this switch, a jumper should
be fitted between terminals 2 and 3 of terminal block X5-02 in the automatic
control unit to close the circuit and enable the burner to be started.

5.5 Calculate prepurge time,
