CSA International and Viessmann Manufacturing announce the voluntary exchange of Kromchröder O-RINGS in gas-fired Vitodens 200 boilers
In cooperation with CSA International, Viessmann Manufacturing Company Inc. of Waterloo, Ontario is announcing a voluntary exchange program for Kromschröder O-rings located in the gas valves of Vitodens 200 boilers manufactured during a specific time period. The O-rings may become brittle over time and may potentially cause a gas leak, which may lead to a fire hazard. No incidents have been reported.
Viessmann is asking consumers and contractors to schedule the 10 minute O-ring exchange with the regular annual boiler maintenance, but no later than July 2009.
Vitodens 200 boilers are used for space heating. They are white and wall-hung boilers, bearing the brands “Viessmann” and “Vitodens 200” in silver letters.
The O-ring Exchange Program applies to of natural gas and propane fired Vitodens 200 boilers manufactured between January 2002 and July 2006. To determine if a boiler is affected by this program, please check the 16 digit serial number on a white bar code label on the boiler. If you are unable to locate the serial number, call your certified contractor.
If the serial number starts with the following 7 digits, then please check the 8th digit.
If the 8th digit is 2, 3, 4, 5, or 6, call your certified contractor to perform the O-ring exchange.
Your certified contractor will be able to obtain O-ring Exchange Kits from Viessmann. The exchange itself will take about 10 minutes. If the annual maintenance for your boiler has been scheduled before July 2009, the O-ring exchange may be performed together with the maintenance.
Consumers may find additional information on the Viessmann website at www.viessmann.ca and consumers and contractors may contact the Viessmann O-ring Information Line toll-free at 1-888-414-9157 at any time 24/7 or write to [email protected].

The installation, adjustment, service and maintenance of this product must be performed by a certified professional contractor who is qualified and experienced in the installation, service and maintenance of hot water boilers.
