Viessmann Manufacturing Co., based in Waterloo, Ont., is recalling its Vitodens 200 boilers because the boiler can leak gas and pose a fire hazard to consumers.

The U.S. Consumer Product Safety Commission advises people to stop using the boilers immediately, weather permitting, and contact Viessman or their certified heating contractor for a free replacement of the boiler’s O-ring.

About 4,600 units were sold in the U.S. between January 2002 and December 2007 for between $4,000 and $7,500 US.

Viessmann advises customers to contact their certified HVAC contractor to open the boiler and locate the serial number on a white label on the side of the boiler, or under the bottom support panel.

Vitodens 100 boilers are not included in this recall.
