Description
The Burnham Boiler 105549-01 Air Proving Switch is a genuine OEM replacement safety component engineered to verify adequate combustion airflow before permitting burner ignition in Burnham boiler systems. By confirming that the draft inducer blower is operating correctly, this switch plays a critical role in safe boiler startup and ongoing system operation — protecting both the equipment and its occupants from unsafe ignition conditions caused by insufficient or blocked airflow.
How It Works
The air proving switch continuously monitors the pressure differential produced by the draft inducer blower. When the correct airflow is established, the switch closes its circuit and signals the control board to proceed with the ignition sequence. If airflow is absent or inadequate, the switch remains open, locking out the burner and preventing a potentially hazardous condition.
