sooner, and may be extended for an additional 180 days, if necessary. On March 23, 1994, Rheem filed an Application for Interim Waiver regarding blower time delay. Rheem's Application seeks an Interim Waiver from the DOE test provisions that require a 1.5-minute time delay between the ignition of the burner and starting of the circulating air blower. Instead, Rheem requests the allowance to test using a 20-second blower time delay when testing its GDG upflow, GLH downflow, GVH horizontal, and GPH upflow/horizontal gas furnaces. Rheem states that the 20-second delay is indicative of how these furnaces actually operate. Such a delay results in an average increase in AFUE of 2.0 percentage points. Since current DOE test procedures do not address this variable blower time delay, Rheem asks that the Interim Waiver be granted. The Department has published a Notice of Proposed Rulemaking on August 23, 1993, (58 FR 44583) to amend the furnace test procedure, which addresses the above issue. Previous waivers for this type of time blower delay control have been granted by DOE to Coleman Company, 50 FR 2710, January 18, 1985; Magic Chef Company. 50 FR 41553, October 11, 1985; Rheem Manufacturing Company, 53 FR 48574, December 1, 1988, 56 FR 2920, January 25, 1991, 57 FR 10166, March 24, 1992, and 57 FR 34560, August 5,1992; Trane Company, 54 FR 19226, May 4, 1989, 56 FR 6021, February 14, 1991 . 57 FR 10167, March . 24, 1992, 57 FR 22222, May 27, 1992, and 58 FR 68138, December 23; 1993; Lennox Industries, 55 FR 50224, December 5, 1990, 57 FR 49700, November 3, 1992, 58 FR 68136, December 23, 1993, and 58 FR 68137, December 23, 1993; Inter-City Products Corporation, 55 FR 51487, December 14, 1990, and 56 FR 63945, December 6, 1991; DMO Industries, 56 FR 4622, February 5, 1991; Heil-Quaker Corporation, 56 FR 6019, February 14, 1991; Carrier Corporation, 56 FR 6018, February 14, 1991, 57 FR 38830, August 27, 1992, 58 FR 68131, December 23, 1993, 58 FR 68133, December 23, 1993 and 59.FR 14394, March 28, 1994; Amana Refrigeration Inc., 56 FR 27958, June 18, 1991, 56 FR 63940, December 6, 1991, 57 FR 23392, June 3, 1992, and 58 FR 68130, December 23,1993; Snyder General Corporation, 56 FR 54960, September 9; 1991; Goodman Manufacturing Corporation, 56 FR 51713, October 15, 1991, 57 FR 27970, June 23,1992 and 59 FR 12586, March 17, 1994; The Ducane Company Inc.. 56 FR 63943, December 6, 1991, 57 FR 10163, March 24,1992, and 58 FR 68134, December 23, 1993; Armstrong Air Conditioning, Inc., 57 FR 899, January 9, 1992, 57 FR 10160, March 24, 1992, 57 FR 10161, March 24, 1992, 57 FR 39193, August 28,1992, and 57 FR 54230, November 17, 1992; Thermo Products, Inc., 57 FR 903, January 9, 1992; Consolidated Industries Corporation, 57 FR 22220, May 27, 1992; Evcon Industries, Inc., 57 FR 47847, October 20,1992; and Bard Manufacturing Company, 57 FR 53733, November 12, 1992. Thus, it appears likely that the Petition for Waiver will be granted for blower time delay. 

### In those instances where the likely success of the Petition for Waiver has been demonstrated based upon DOE having granted a waiver for a similar product design, it is in the public interest to have similar products tested and rated for energy consumption on a comparable basis. Therefore, based on the above, DOE is granting Rheem an Interim Waiver for its GDG upflow, GLH downflow, GVH horizontal, and GPH upflow/horizontal gas furnaces. Pursuant to paragraph (e) of § 430.27 of the Code of Federal Regulations part 430, the following letter granting the Application for Interim Waiver to Rheem was issued. Pursuant to paragraph (b) of 10 CFR 430.27, DOE is hereby publishing the "Petition for Waiver" in its entirety. The petition contains no confidential information. The Department solicits comments, data, and information respecting the petition.

March 23.1994. Mr. Cyrus Nasseri, Assistant Secretary

, Conservation, and Renewable Energy. United States Department of Energy, 1000 Independence Avenue, SW., Washington, DC 20565. Dear Mr. Nasseri: This is

. a petition for waiver and application for interim waiver submitted pursuant to title 10 CFR 430.27. Waiver is requested from the furnace test procedure as prescribed in appendix N to Subpart B of Part 430. The test procedure requires a 1.5 minute delay between burner and blower start

-up. Rheern is requesting authorization to use a 20 second delay instead of 1.5 minutes for our series (-)GDG upflow, (-)GLH'downflow, (- )GVH horizontal, and (- )GPH upflow/horizontal residential gas-fired furnaces. Rheem will be manufacturing these appliances with an electronic device that controls the blower operation on a timing sequence as opposed to temperature. Improved energy efficiency is achieved by reducing on cycle losses. Under the Appendix N procedures, the stack temperature is allowed to climb at a faster rate than it would with a 20 second blower on time, allowing energy to be lost out of the vent system. This waste of energy would not occur in actual operation. If this petition is granted, the true blower on time delay would be used in the calculations. The current test procedures do not give Rheem credit for the energy savings which averages approximately 2%. This improvement is an average reduction of 20% of the normal on cycle energy losses. Rheem Is of the opinion that a 20% reduction is a worthwhile energy savings. Rheem has been granted previous waivers regarding blower on time to be used in the efficiency calculations for our (-)GEB and (- )GKA series condensing furnaces and/or (- )GDE, (- )GLE, (- )GDG, (- )GLG and (- )GVG series furnaces. Several other manufacturers of gas furnaces have also been granted a waiver to permit calculations based on timed blower operation. Also. ASHRAE Standard 103-1993, paragraph 9.5.1.2.2 specifically addresses the use of timed blower operation. Confidential and comparative test data is available to you upon your request. confirming the above energy savings. Manufacturers that domestically market similar products are being sent a copy of this petition for waiver and petition for interim waiver. Sincerely, Daniel J. Canclini, Vice-President, Product Development and Research Engineering. 1FR Doc. 94-10579 Filed 5-2-94; 8:45 aml
