Lochinvar has recalled almost 38,000 Lochinvar, A.O. Smith, and State ProLine residential condensing boilers, combination boilers, and packaged systems sold between August 2016 and June 2020.

The boiler’s flue grommet can deteriorate and dislodge during use, allowing the boiler to emit carbon monoxide, posing a risk of CO poisoning, according to the recall notice from the Consumer Product Safety Commission.

Lochinvar has received seven reports of the boiler’s flue grommets deteriorating, including one report of two nonfatal injuries involving CO poisoning and two reports of CO emission not involving an injury, according to the CPSC.

If you have one of these boilers, schedule a repair as soon as possible. In the meantime, make sure you have a working CO alarm outside every bedroom and on every level of your home.

The recall includes dozens of models. To find the model information and serial number on your boiler, look for the brand name on the front of the unit, and the model and serial number on the data plate located on the boiler’s rating plate, which appears on the outer jacket of the boiler or on the underside of the removable front jacket plate. 

In our member survey of 16 brands of boilers, Lochinvar earns a middle-of-the-pack rating for predicted reliability but high marks for owner satisfaction. Consumer Reports does not test boilers at this time.
