Boilers Recalled for Carbon Monoxide Risk

Owners of the 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.

Viessmann Manufacturing Company (U.S.) Inc., of Warwick, R.I., has recalled about 4,300 units of the Viessmann Vitodens 200-W wall mount boiler because the boiler's heat exchanger back plate can corrode and leak flue gases, allowing the boiler to emit excessive amounts of carbon monoxide.

The recall was announced April 25 in the United States and Canada. About 2,900 of the recalled products were sold in the United States and about 1,400 were sold in Canada. They were sold by Viessmann authorized dealers from September 2014 through October 2018 for between $2,700 and $4,200.

Owners of the 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 CO alarm installed outside of sleeping areas in the home, according to the CPSC recall notice.

The owners can contact Viessmann at 800-288-0667 from 8:30 a.m. to 5 p.m. ET weekdays, by emailing recall@viessmann.com, or by visiting www.viessmann.com and clicking on "Important Notice" located in the middle of the homepage for more information.

The 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 that is 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.
