Viessmann has recently issued a recall for its Vitodens 200-W and Vitodens 222-F series boilers, because, according to the CPSC, 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.
The recalled products can be identified by the model numbers B2HB 19, B2HB 26, B2HB 35, B2TB 19, and B2TB 35. They were sold at Viessmann Authorized Dealers.
