recall signIn cooperation with the Consumer Product Safety Commission, Weil-McLain has announced a voluntary recall of about 1,800 Williamson-Thermoflo GWS and GWI gas boilers. If a leak occurs in the vent piping, the boilers can leak carbon monoxide into the building in which they are installed, posing a risk of CO poisoning. No injuries have been reported.

Manufactured in the United States and sold by plumbing and heating wholesale distributors to plumbers and contractors from October 2001 through December 2007 for between $1,500 and $2,700, this recall involves cast iron, gas fired boilers used for space heating. Please check the CPSC press release for more information.

Consumers are advised to contact their installers for a free safety inspection and repair. For more information, contact Williamson-Thermoflo at (866) 783-9516, or visit their website at
