Duroflame Air pressure sensor

The Vacuum sensor is used to detect under- or over-pressure and close a contact that signals the stove controller, and at the same time physically cuts power to the Auger. In the Abel the Pressure sensor is connected as a protection against too much pressure in the chimney. That means if the chimney gets blocked, the pressure rise from the fan will cause an error. The contact will open and no power will travel to the Auger. Part number 10068
