Viessmann Recalls Boilers Due to Carbon Monoxide Hazard

Viessmann a manufacturer of residential and commercial boilers, in conjunction with the U.S. Consumer Product Safety Commission (CPSC), has announced a recall of certain boilers due to potential Carbon Monoxide hazard.

Boiler Safety Notice

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. This recall involves the Vitodens 200-W and Vitodens 222-F series boilers used for space or domestic water heating. There are five affected models in a specific serial number range. The Vitodens 200-W is a wall hung unit, housed in a white metal box about 38 inches high and 18 inches wide. The Vitodens 222-F is a floor mounted unit, housed in a white metal box about 68 inches tall and 24 inches wide. The name “Vitodens” is printed on the label on the outside of the boiler box. The product name and model number can be found on the left side of the boiler cover. The serial number can be found on the underside of the wall mounted boiler and on the center section on the floor mount model.

Consumers with recalled boilers should immediately contact the installer or distributor of the boiler to schedule a repair. Consumers who continue use of the boilers while awaiting repair, should have a working carbon monoxide alarm outside of sleeping areas and on every level of the home.
