Description
The recall involves the Buderus GB312 gas-fired, floor standing condensing boilers. Model numbers included in this recall are: 312/90, 312/120, 312/160, 312/200, 312/240 and 312/280. "BUDERUS GB312" is printed on the front of the boiler. The boilers are blue, approximately 60 inches high and between 39 and 55 inches wide.
Hazard
A problem with the boiler's ignition due to insufficient output voltage from the boiler's transformer can damage the boiler's venting. This can result in leaking flue gases, posing a risk of carbon monoxide poisoning to consumers.
Remedy
Bosch has directly contacted consumers who purchased the recalled boilers, inspected and, if necessary, repaired the boilers.
Incidents and injuries
No incidents or injuries reported in the United States. Two incidents were reported in Germany, neither of which resulted in injury.
