Lochinvar of Lebanon, Tenn., is recalling about 38,000 Lochinvar condensing residential boilers sold in the U.S. and Canada.
The boiler’s flue grommet can deteriorate and dislodge during use and allow the boiler to emit carbon monoxide, posing a risk of carbon monoxide poisoning.
The firm has received seven reports of flue grommets deteriorating, including one report of two nonfatal injuries involving carbon monoxide poisoning, and two reports of carbon monoxide emission not involving an injury.
This recall includes residential condensing boilers, combi boilers and packaged systems sold after August 2016.
The following model numbers are included in the recall:
