The gas pressure switch must react to excessive gas pressure in the
burner. Start can only be done by manual reset (gas burner control or
overpressure switch).
The switch blocks the burner if gas pressure between gas valve and
burner becomes too high. The overload protection switch can be
connected so that it provides automatic restart or that the burner is
blocked, see S10 or S16 in the wiring diagram. The system’s safety
regulations control connection options.
