U.S. Boiler is recalling approximately 26,310 cast iron hot water boilers, including model series ESC, PVG, and SCG, manufactured between December 2005 and February 2013. These gas-fired units were sold for between $1,700 and $4,900 and are used for residential heating. The recall was issued because a internal switch can fail to shut down the burners if the vent system becomes blocked, causing the boiler to release dangerous levels of carbon monoxide. While no injuries have been reported, consumers are eligible for a free in-home safety inspection and repair.
A malfunctioning air pressure switch may allow the boiler to continue burning fuel even if the exhaust vent is blocked. This can lead to a buildup and emission of carbon monoxide, a colorless and odorless gas that can cause illness or death if inhaled.
Consumers with recalled boilers should immediately contact the installer or distributor from whom they purchased the boiler or U.S. Boiler to schedule a free in-home safety inspection and repair. Consumers who continue use of the boilers while awaiting repair, should have a working carbon monoxide alarm installed outside of sleeping areas in the home.
