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.
