The blocked vent switch (BVS) can fail to shut down the burners if the boilers are installed at altitudes above 2,000 feet and the vent system becomes blocked. In such an event, the boiler can emit excessive amounts of carbon monoxide into the building, posing a carbon monoxide (CO) poisoning hazard to consumers.
Consumers with the recalled boilers should immediately contact Crown Boiler for a free repair that includes a free replacement main burner gas orifice, and a free replacement blocked vent switch if needed. Consumers who continue using the recalled boilers while awaiting repair should have working carbon monoxide alarms installed outside of sleeping areas and on each floor of the home. Consumers can review Protect Your Family from Carbon Monoxide Poisoning | CPSC.gov for more information about preventing carbon monoxide poisoning.
