About 1,100 Crown Aruba gas-fired hot water boilers are being recalled due to a dangerous defect that carries with it the risk of carbon monoxide poisoning.
At altitudes over 2,000 feet, the blocked vent switch can fail to shut down the boilers’ burner, according to the Consumer Product Safety Commission’s recall notice. This can lead to the vent system becoming blocked and emitting excessive amounts of carbon monoxide into the building. This poses a dangerous carbon monoxide poisoning hazard to building occupants. So far, there have been no reports of injuries.
The boilers were sold between July 2012 and December 2023 by heating and plumbing contractors nationwide and at wholesale distributors.
Facility managers who have installed the boilers in their facilities should immediately contact the manufacturer for a free repair. The repair includes a free replacement main burner gas orifice, and a free replacement blocked vent switch if needed.
