Energy Conservation Program for Consumer Products: Test Procedures for Furnaces and Boilers

The Department of Energy (the Department or DOE) adopts as a Final Rule an Interim Final rule, published on October 14, 1997, in which DOE amended a provision of its recently promulgated final rule that prescribed revised test procedures to determine the energy efficiency of furnaces and boilers. Under the amendment, the test procedures will provide that the flue collector box on a furnace or boiler with a power burner or draft inducer need not be insulated before the start of the cool-down test.
