Reason for Recall

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.
