Americans Nationwide Get Sudden Warning About Carbon Monoxide in Their Home

A variety of gas-fired hot water boilers have been recalled due to the potential for "excessive amounts" of carbon monoxide to leak into your home.

The following boiler brands manufactured by U.S. Boiler Company LLC, of Lancaster, Pennsylvania, recalled a number of their products on Thursday: U.S. Boiler, New Yorker Boiler, Advantage, FORCE and Archer.

The recall announcement shared on the United States Consumer Product Safety Commission (CPSC) website said, "The blocked vent switch (BVS) can fail to shut down the burners if the boilers are installed at altitudes above 5,400 feet and the vent system becomes blocked.

"In such an event, the boiler can emit excessive amounts of carbon monoxide into the home, posing a carbon monoxide (CO) poisoning hazard to consumers."

There have been no reported incidents or injuries related to the recall as of Thursday.

About 2,5000 units of the recalled boilers were sold nationwide from February 2009 to November 2023 by independent heating and plumbing contractors and wholesale distributors for between $2,000 and $4,000.

Here are the boiler models that have been recalled:

• U.S. Boiler ES2 models ES23, ES24, ES25, ES26, ES27, ES28, ES29 (with or without "-N" or "-P" suffix)
• U.S. Boiler Series 3 models 303, 304, 305, 306, 307, 308, 309 (with or without "-N" or "-P" suffix)
• U.S. Boiler X-2 models X-202, X-203, X-204, X-205, X-206, X-207, X-208, X-209
• New Yorker CG-E models CG30E, CG40E, CG50E, CG60E, CG70E, CG80E, CG90E
• New Yorker CG-F models CG20F, CG30F, CG40F, CG50F, CG60F, CG70F, CG80F, CG90F
• Advantage AG models AG3, AG4, AG5, AG6

• Archer Boilers Lancer models LCR-2-038, LCR-3-068, LCR-4-102, LCR-5-136, LCR-6-170

If you have a recalled boiler, the recall notice advises you to immediately contact U.S. Boiler to get a free repair. The repair includes a replacement main burner gas orifice and a replacement blocked vent switch "if needed."

If you do continue to use a recalled boiler while waiting for it to be repaired, you should have working CO alarms outside of sleeping areas and on each floor of your home.

Since CO is an odorless and colorless gas, it is important to know the symptoms of exposure.

The CPSC lists the following initial symptoms of low to moderate CO poisoning:

• Headache
• Fatigue
• Shortness of breath
• Nausea
• Dizziness

Here is the list of more severe symptoms from high-level CO poisoning:

• Mental confusion
• Vomiting
• Loss of muscular coordination
• Loss of consciousness
• Ultimately death
