Weil-McLain Recalls Ultra Series Boilers for Carbon Monoxide Hazard

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.
