CPSC campaign 19111
Hazard
The boiler heat exchanger back plate can corrode and leak flue gases, allowing the boiler to emit excessive amounts of carbon monoxide, posing a CO poisoning hazard to consumers.
Remedy
Consumers with recalled boilers should immediately contact the installer or distributor from whom they purchased the boiler or Viessmann to schedule a free in-home safety inspection and repair. Consumers who continue the use of the boilers while awaiting repair, should have a working carbon monoxide alarm installed outside of sleeping areas in the home.
