Failures have been found in some components of "Kerosene-fired water heaters and Kerosene fired water heater fitted bath-tubs" manufactured by Noritz Corporation,TOTO Ltd. (manufactured by TOTO Yupro Ltd) and Choshu Industry. Continuous use of the relevant products has caused multiple accidents including fires and internal burnouts of the appliances. In response,three companies have placed company announcements in newspapers and offered inspection and repair services to prevent further accidents. However,similar accidents have continued to occur despite their efforts. NITE encourages consumers to check the manufacturer and model of the products in use. If the products you have are subject to recall,we ask you to discontinue using them and contact your manufacturer.
