### Office of Conservation and Renewable Energy Energy Conservation Program for Consumer Products ; Granting of the Application for Interim Waiver and Publishing of the Petition for Waiver of Furnace Test Procedures From Carrier Corp. ( Case No. F-042) AGENCY : Office of Conservation and Renewable Energy, Department of Energy. SUMMARY : Today's notice publishes a letter granting an Interim Waiver to Carrier Corporation (Carrier) from the existing Department of Energy (DOE) test procedures for furnaces regarding blower time delay for the company's 58GFA/394HAD, 58PAP/383KAD, 58DFA/396HAD, 58RAP/373LAD, GAlA,'and GAZA induced draft furnaces. _ Today's notice also publishes a "Petition for Waiver" from Carrier. Carrier's Petition for Waiver requests DOE to grant relief from the DOE test procedures relating to the blower time delay specification. Carrier seeks to test using a blower delay time of 45 seconds for its 58GFA/394HAD, 58PAP/383KAD, 58DFA/396HAD, 58RAP/373LAD, GAZA, and GAZA induced draft furnaces instead of the specified 1.5- minute delay between burner on-time and blower on-time. DOE is soliciting comments, data, and information respecting the Petition for Waiver, DATES : DOE will accept comments, data, and information not later than February 24.1992. to the Energy Policy and Conservation Act (EPCA), Public Law 94-163, 89 Stat. 917, as amended by the National Energy Conservation Policy Act (NECPA), Public Law 95-619 , 92 Stat

-357, which requires DOE to prescribe standardized test procedures to measure the energy consumption of certain consumer products , including furnaces. The intent of the test procedures is to provide a comparable measure of energy consumption that will assist consumers in making purchasing decisions. These test procedures appear at 10 CFR part 430, Subpart B. DOE amended the prescribed test procedures by adding 10 CFR 430.27 on September 26,1980 , creating the waiver process. 45 FR 64108

. Thereafter DOE further amended the appliance test procedure waiver process to allow the Assistant Secretary for Conservation and Renewable Energy (Assistant Secretary ) to grant an Interim Waiver from test procedure requirements to manufacturers that have petitioned DOE for a waiver of such prescribed test procedures

. 51 FR 42823, November 26. 1986. 

### The waiver process allows the Assistant Secretary to waive temporarily test procedures for a particular basic model when a petitioner shows that the basic model contains one or more design characteristics which prevent testing according to the

Carrier's Application for Interim Waiver does not provide sufficient information to evaluate what , if any , economic impact or competitive disadvantage Carrier will likely experience absent a favorable determination on its application

. However , 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, Canter's Application for an Interim Waiver from the DOE test procedures for its 58GFA/394HAD, 58PAP/383KAD, 58DFA/396HAD, 58RAP/373LAD, GAZA, and GAZA induced draft furnaces regarding blower time delay is granted. Carrier shall be permitted to test its line of 58GFA/394HAD , 58PAP/383KAD , 58DFA/ 396HAD, 58RAP/373LAD, GALA, and GAZA induced draft furnaces on the basis of the test procedures specified in 10 CFR Part 430, Subpart B, Appendix N, with the modification set forth below. (i) Section 3.0 in Appendix N is deleted and replaced with the following paragraph: 3.0 Test Procedure

. Testing and measurements shall be as specified in section 9 in ANSI /AHRAE 103-82 with the exception of sections 9.2.2, 9

. 3.1, and 9.3.2, and the inclusion of the following additional procedures: - (ii) Add a new paragraph 3.10 in Appendix N as follows: 3.10 Gas - and Oil-Fueled Central Furnaces. After equilibrium conditions are achieved following the cool

. in which case the fan control shall be permitted to start the blower

This Interim Waiver may be revoked or modified at any time upon a determination that the factual basis underlying the application is incorrect. The Interim Waiver shall remain in effect for a period of 180 days or until DOE acts on the Petition for Waiver, whichever is sooner, and may be extended for an additional 180- day period , if necessary. Sincerely. J. Michael Davis, Assistant Secretary Conservation and Renewable Energy. October 21.1991. The Assistant Secretary for Conservation and Renewable Energy, United States Department of Energy, 1000 Independence Avenue SW., Washington. DC 20585. Subject : Petition For Waiver and Application for Interim Waiver. Gentlemen: This is a Petition for Waiver and Application for Interim Waiver which are submitted pursuant to title 10 CFR 430.27 as amended November 14, 1986

. Waiver is requested from Test Procedures for Measuring the Energy Consumption of Furnaces found in appendix N to subpart B of part430. Under the existing Test Procedure, a 1.5 minute time delay between burner and blower startup is required: Carrier requests a waiver from the specified 1.5 minute delay. In its place , we request the use of a 45-second delay on Carrier's line of 58GFA / 394HAD. 58PAP/383KAD, 58DFA/396HAD, 58RAP/ 373LAD , GAZA and GA2A induced draft furnaces. The time delay in all lines of equipment is fixed within the furnace control, and cannot be adjusted by the installer or servicer. The current test procedures do not credit Carrier for the energy savings associated with the shorter blower time delays. Test data on our mid-efficiency furnaces show a 7.9% decrease in the heat

- up cycle energy loss when using the 45

- second delay, resulting in an increase in AFUE of approximately 0.8 AFUE points

. Confidential supporting test data is available upon request. Carrier is confident that a waiver will be granted for public policy reasons in the light of previous rulings in which DOE granted waivers of this type to Lennox Industries, Inter-City Products, Amana, Rheem Manufacturing, and the Trane Company. In addition, an interim waiver of this type wasrecently granted to Goodman and SnyderGeneral. Lastly, the proposed ASHRAE 103-88 allows the use of non-adjustable bloweron-delays in place of the specified 90 seconds. Both DOE and NIST were instrumental in the development of Standard i03-89, and suggested it be included so as toaddress furnaces with fixed blower-ondalays. Respectfully, Edward A.
