Hazard
The boiler's flue collector can crack if exposed to a high impact event in the burner chamber, which can allow the boiler to emit carbon monoxide, posing a risk of carbon monoxide poisoning.
Remedy
Consumers with the recalled boilers should immediately contact the installer or a qualified technician to schedule a free repair. The repair will consist of installing a steel plate, which will be affixed to the base of the flue collector to act as a reinforcement. Consumers who continue use of the boilers while awaiting repair should have working carbon monoxide alarms outside of sleeping areas and on each floor of the home.
Incidents and injuries
Lochinvar has received nine reports of broken flue collectors. Lochinvar has received no reports of injury.
