Plain-English summary

Bosch Thermotechnology is recalling approximately 170 Buderus GB125-35 oil-condensing boilers. The recall is due to a hazard where the siphon can become blocked, leading to delayed ignition that may damage the boiler's exhaust system and create a carbon monoxide hazard. The affected boilers have a blue enclosure with the Buderus brand name printed on the outside and the GB125-35 model number on a data plate near the top right side.

These boilers were distributed by Bosch Thermotechnology Corp. and installed by independent contractors nationwide from June 2008 through September 2012. The units were sold for about $6,000. No injuries have been reported in the United States.

Consumers should immediately contact Bosch for a free repair. Those who continue to use the boilers while awaiting repair should install a working carbon monoxide alarm outside of sleeping areas in the home. Consumers can contact Bosch Thermotechnology at 800-323-1943 or via email at [email protected] for more information.
