WASHINGTON, D.C. - The U.S. Consumer Product Safety Commission (CPSC) is announcing a recall of about 30,000 furnaces sold in California. Seven firms are offering to repair or replace certain furnaces, which were sold under their own labels, but were manufactured by Consolidated Industries Inc. The units involved are gas-fired horizontal furnaces equipped with steel "NOx" rods installed above the burners and are commonly called NOx rod furnaces. These furnaces pose a substantial risk of fire.
