Weil-McLain Recalls Ultra Series Boilers for Carbon Monoxide Hazard
What was recalled
The recall involves Weil-McLain Ultra 80, Ultra 105, Ultra 155, Ultra 230 and Ultra 310 condensing, high-efficient, gas-fired boilers for space heating. The user's manual and installation manual have "Ultra Gas-Fired Water Boiler" on the cover. The boilers are wrapped in a glossy silver/flat black jacket and either stand on the floor or are wall-mounted. The serial numbers range from CP5071716 through CP5327000. When the panel on the front of the boiler is removed, a bar-coded label with the serial number is located on the lower right hand side of the boiler itself. "Weil-McLain" is written on the front panel of the boilers.
Hazard
These boilers were manufactured for use with natural gas, but could have a blue tag incorrectly indicating to installers that they are intended for use with LP (propane) gas. If an installer connects one of the boilers to LP gas without installing a propane conversion kit, carbon monoxide (CO) can build up due to incomplete combustion, posing a risk of CO poisoning.
Injuries
Weil-McLain is aware of one incident where two consumers reported CO poisoning when the boiler installed in their home was connected to LP gas.
