Viessmann Manufacturing Company (U.S.) of Warwick, R.I. , is recalling about 4,300 Vitodens boilers sold in the U.S., and Canada.
The boiler heat exchanger back plate can corrode and leak flue gases, allowing the boiler to emit excessive amounts of carbon monoxide, posing a poisoning hazard.
No incidents or injuries are reported.
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.
