What are boiler air switches?
A boiler air switch is an air pressure switch that proves the burner fan is moving enough combustion air. If airflow fails, the switch opens and the burner control shuts the fuel off.
This is a key safety interlock. Therefore, the switch must suit the pressure range of the burner and be set correctly.
