Smith 100109973 Blocked Inlet Switch is a critical safety component designed for high efficiency condensing boilers and water heaters. As a normally closed air pressure switch, its primary function is to monitor the intake system for airflow restrictions. If the intake air connection screen becomes clogged or the vent piping is obstructed, the switch detects a fall in pressure and opens the electrical circuit, instantly shutting
