Consolidated Industries asks that the Interim Waiver be granted.
Previous waivers for this type of timed 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, 1988.55 FR 3253, January 31, 1990. and 55 FR 37521.

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 Consolidated Industries an Interim Waiver for its MAA series of gas furnaces. Pursuant to paragraph (e) of section 430.27 of the Code of Federal Regulations, the following letter granting the Application for Interim Waiver to Consolidated Industries 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. DOE solicits comments, data, and information respecting the petition.

Gentlemen: This letter is in reference to my letter of September 18, IM, to Petition for Waiver and Application for Interim Waiver as submitted in compliance with title 10 CFR 430.27. - By this letter Consolidated Industries is amending our September 18, 1991 request such that our MAA series furnaces will be tested with a 30 second time delay used in place of the current test procedure's 1.5 minute time delay . Thirty seconds is the maximum time delay, including manufacturing tolerance

, of the nonadjustable time delay relay used in the MAA Series furnaces. Test results show an average of 0.8% improvement in AFUE using th4 30 seconds fixed time delay in place of the present standards 1.5 minute time delay

-Federal Register / Vol. 57, No. 8 I Thursday, January 9, 1992 / Notices

U.S. Department of Energy, 1000 Independence Avenue SW Washington, DC20585 Gentlemen:: This Petition for Waiver and Application for Interim Waiver is submitted in compliance with title 10 CFR 430.27. This request is for a modification to the Test Procedures for Measuring the Energy Consumption of Furnaces found in appendix N to subpart B of Part 430. The current test procedure uses a 1.5minute time delay between the burner startup and the blower start-up. Consolidated Industries' MAA series of furnaces utilizes a 25 second non-adjustable fixed time delay between the burner ignition and blower startup. This timer has a manufacturer's tolerance of ±5 seconds. For the MAA series of furnaces, Consolidated industries is requesting that the fixed time delay be substituted for the current test procedure's 1.5 minute time delay. We submit that the current test procedure using the 1.5 minute blower start-up time delay requires a bypass of the furnace safety limit switch and does not represent the true product performance and efficiency. The MAA furnace series has a light weight, compact heat exchanger that was designed to heat up very quickly with an ensuing blower start-up time optimized at 25 seconds. The advanced beat exchanger design along with improved operating controls has improved the efficiency of this furnace in such a way that the current standard does not credit Consolidated Industries for the true efficiency improvements of this furnace. The product performance will be more accurately depicted using the proposed ASHRAE Standard 103-1988 which accounts for the design flexibility and improvement without the penalty incurred by using the current test procedure. The test results show an average of 0.9% improvement in AFUE using the 25 second fixed time delay. Other manufacturers have submitted similar waiver requests for similar reasons. Data and documentation can be supplied at your request This waiver request letter has been sent to GAMA and gas furnace manufactures that market similar products. Sincerely. Richard H. Weber, President Consolidated Industries Corp. [FR Doc. 92-530 Filed 1-8-92; 8:45 am]
