Certain Lochinvar condensing gas boilers and condensing gas combi boilers have been recalled in Canada due to the risk of carbon monoxide poisoning. The boiler’s flue grommet can deteriorate and dislodge during use and allows the boiler to emit carbon monoxide. The recall was announced on June 18.
The units contain a silicone flue grommet that is fitted through a small hole in the flue pipe and seals and holds a temperature sensor to the flue pipe. Over time, it may be possible for the silicone material to break down and fall from the mounting hole in the flue pipe. If this occurs, the vacant mounting hole allows flue gases to escape, posing a risk of exposure to carbon monoxide.
Consumers should contact the installer or technician to schedule a free repair of the unit. The recall was made by Health Canada, the United States Consumer Product Safety Commission, and Lochinvar.
This recall involves certain condensing gas boilers and condensing gas combi boilers manufactured between Aug. 16, 2016, and May 28, 2019. All units sold by Lochinvar to Canadian customers were Lochinvar branded. The brand, model number, and serial number can be found on the data plate on the unit located either on the exterior left side of the jacket or the inside of the removable front jacket panel.
Products with the following model numbers are affected by the recall – EPB080N, KHB155N, WHB199L, EPB110N, KHB199L, WHB199N, EPB150N, KHB199N, WHB285N, EPB199N, KHB285N, WHB399N, EPC110N, NKC110N, WHN056, EPC110N-CAN, NKC150N, WHN086, EPC150N, NKC199N, WHN111, EPC199N, WHB055N, WHN156, KHB055N, WHB085N, WHN200, KHB085N, WHB110N, WHN286, KHB110N, WHB155N, and WHN286-8647.
No reports of incidents or injuries have been recorded in Canada. In the United States, the company has received seven reports of boiler’s flue grommets deteriorating, including one report of two non-fatal injuries involving carbon monoxide poisoning, and two reports of carbon monoxide emissions not involving an injury.
Around 3,642 units of the affected products were sold in Canada between August 2016 and June 2020.
