Notice of Petition for Waiver of Raypak Inc. From the Department of Energy Commercial Water Heater Test Procedure

This notice announces receipt of and publishes a petition for waiver from Raypak Inc. (Raypak) seeking an exemption from specified provisions applicable to standby loss of the U.S. Department of Energy (DOE) test procedure for commercial water heating equipment. The waiver request pertains to Raypak's specified models of commercial instantaneous water heaters containing 10 gallons or more of water. In its petition, Raypak contends that its specified water heater models that employ tube-type heat exchangers and are designed to be flow activated cannot be accurately tested using the currently applicable DOE test procedure. Consequently, Raypak seeks to use an alternate test procedure to address certain issues involved in testing the specific basic models identified in its petition. DOE solicits comments, data, and information concerning Raypak's petition and its suggested alternate test procedure.
