### Background
The Energy Conservation Program for Consumer Products (other than automobiles) was established pursuant 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. 3286, the National Appliance Energy Conservation Act of 1987 (NAECA), Public Law 100-12, and the National Appliance Energy Conservation Amendments of 1988 (NAECA 1988), Public Law 100-357, 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 has amended the prescribed test procedures by adding 10 CFR 430.27 on September 26, 1980, creating the waiver process. 45 FR 64108. DOE further amended the Department's 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 requirement 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 prescribed test procedures or when the prescribed test procedures may evaluate
the basic model in a manner so unrepresentative of its true energy consumption as to provide materially inaccurate comparative data. Waivers generally remain in effect until final test procedure amendments become effective, resolving the problem that is the subject of a waiver. The interim waiver provisions, added by the 1986 amendment, allow the - Assistant Secretary to grant an interim waiver when it is determined that the applicant will experience economic hardship if the Application for Interim Waiver is denied, if it appears likely that the petition for waiver will be granted, and/or the Assistant Secretary,

determined that it would be desirable for public policy reasons to grant immediate relief pending a determination on the petition for waiver.
On January 29,1990, Carrier filed an Application for an Interim Waiver regarding blower time delay. Carrier'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, Carrier's requests the allowance to test using a 66 second blower time delay when testing its'58SSC/395C, 58PAV/ 383K, 58DHC/376C, 58RAV/373L
induced draft furnaces and 60 second blower time delay when testing its 58SXA/398A, 58DX/399A induced draft condensing furnaces . Carrier states that the 66 second, and 60 second delay, respectively are indicative of how these furnaces actually operate. Such a delay results in an energy savings of approximately 0.4 and 0.7 percent, respectively. Since current DOE test procedures do not address this variable blower time delay, Carrier asks that the interim waiver be granted.
Previous waivers for this type of timed blower delay control have been granted by the Department to the Coleman Company, 50 FR 2710, January 18, 1985, the Magic Chef Company, 50 FR 41553, October 11, 1985 , the Rheem Manufacturing Company, 53 FR 48574, December 1. 1988, and the Trane Company, 54TR 19226, May 4, 1989. Thus, it appears likely that the Petition for Waiver will be granted for blower time delay.
The Department finds that it would be desirable for public policy reasons to grant Carrier's Application for Interim Waiver. Specifically, 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's interest to have the similar products tested and rated for energy consumption on a comparable basis.
Pursuant to paragraph (b) of 10 CFR 430.27, DOE is hereby publishing the "Petition for Waivers" in its entirety. The petition contains no confidential information. DOE solicits comments, data, and information respecting the petition.
In addition, pursuant to paragraph (e) of § 430.27 of the Code of Federal Regulations, the following letter granting the Application for Interim Waiver was issued to Carrier Corporation. Issued in Washington

AssistantSecretars: Conservation and Renewable Energy.

Department of Energy
March 29, 19W. Mr. Edward A Bally

, Vice President Carrier Corporation, P.O. Box 4808, Carrier Park, Syracuse. NY 13221.
Dear Mr

. Bally: This is in response to your January 29

, Application for Interim
Waiver and Petition for Waiver from the Department of Energy (DOE) test procedures for furnaces when testing Carrier Corporation
58SSC/395C , 58PAV/ 383K , 58DHC/376C,
58RAV/ 373Linduced draft furnaces and 58SY,A/398A, 58DX/399A induced draft condensing furnaces regarding blower time delay.
Pursuant to the Energy Policy and Conservation Act, as amended, the Department has prescribed test procedures to measure the energy consumption of certain major household appliances

, including furnaces

. The intent of the test procedures is to provide a comparable measure of energy consumption that will assist consumers in making purchase decisions

. These That procedures appear in the Code of Federal Regulations at 10 CFR part 430, subpart B. DOE amended the test procedure regulations on September 26, 19W [45 FR 64108] and November 26, 1986, (51 FR 42823) by adding paragraph 43027. These provisions allow the Assistant Secretary for Conservation and Renewable Energy 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 of the basic model according to the prescribed test procedures or when the prescribed test procedures may evaluate the basic model in a manner so unrepresentative of its true energy consumption characteristics as to provide materially inadequate comparative data

. The 1986 amendments added provisions allowing the Assistant Secretary to grant an interim waiver for a particular basic model when a petitioner
demonstrates the likely success of the petition

- for waiver

. It is determined that the applicant will experience economic hardship if the Application for Interim Waiver is denied and/or the Assistant Secretary
determines that it would be desirable for public policy reasons to grant immediate relief pending a determination on the petition
for waiver. Previous waivers for timed blower delay control have been granted to the Coleman Company

, 50 FR 2710

, January 18

, 1985, Magic Chef Company

, 50 FR 41553

, and the Trane Company, 54 FR 19226, May 4, 1989. Carrier's Application for Interim Waiver does not provide sufficient information for the Department of evaluate what

, if any, economic impact or competitive disadvantage Carrier will likely experience absent a favorable determination on the application for interim waiver. Carrier feels that its competitive position in the marketplace would be compromised if this Application for

Interim Waiver is not granted. However, the Department finds that it would be desirable for public policy reasons to grant Carrier's Application for Interim Waiver. Specifically,
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's interest to have the similar products tested and rated for energy consumption on a comparable basis.
Therefore, Carrier's Application for an Interim Waiver requesting a change from the DOE test procedures for its 58SSC/395C, 58PAV/383K, 58DHC/376C, 58R.AV/373L
induced draft furnaces and 58SXA/398A, 58DX/399A induced draft condensing furnaces regarding blower time delay is granted. Carrier shall be permitted to test its line of 58SSC/395C, 58PAV/383K, 58DHC/376C,
58RAV/373L induced draft furnaces and 58SXA/398A, 58DX/399A induced draft condensing furnaces on the basis of the test procedures specified in 10 CFR part 430, with
the modification set forth below. (i) Section 9.3.1 of ANSI/ASHRAE Standard 103-1982 is deleted and replaced with the following paragraph:

Gas- and Oil-Fueled Central Furnaces. After equilibrium conditions are achieved following the cool-down test and the required

measurements performed, turn on the furnace
and measure the flue gas temperature, using the thermocouple grid described above, at 0.5
and 2. 5 minutes after the main burner(s)

comes on . After the burner start -up, delay the blower start-up by 1.5 minutes (t-), unless: (1) The furnace employs a single motor to drive the power burner and the indoor air
circulation blower, in which case the burner and blower shall be started together; (2) the furnace is designed to operate using an unvarying delay time that is other than 1.5 minutes, in which case the fan control shall be permitted to start the blower, or (3) the delay time results in the activation of a temperature safety device which shuts off the burner, in which case the fan control shall be permitted to start the blower. In the latter

case , if the fan control is adjustable, set it to start the blower at the highest temperature. If the fan control is permitted to start the blower, measure time delay, ( t-), using a stop watch. Record the measured temperatures. During the heat-up test for oil-fueled furnaces, maintain the draft in the flue pipe with .- 0.01 inch of water gauge of the manufacturer's recommended on-period
draft. This interim waiver is based upon the presumed validity of statements and all allegations submitted by the company. 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 until the Department of Energy issues a
determination on Carrier's Petition for
Waiver.

Sincerely,
1. Michael Davis, P.E. Assistant Secretary. Conservation and Renewable Energy.
January 29,1990. The Assistant Secretary for Conservation and Renewable Energy, United States Department of Energy, 10170 Independence Avenue, SW., Washington,
DC 20585. Gentlemen: Subject: Petition for Waiver And Application For Interim Waiver
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 part 430. 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 86 second delay on Carrier's line of 58SSC/395C, 58PAV/383K, 58DHC1376C, and 5BRAV/373L induced draft mid-efficiency furnaces. We are also requesting the use of a 60 second delay on our line of 58SXA/398A and 58DX/399A induced draft condensing furnaces. The time delays in both lines of equipment are 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 5% decrease in the heat-up cycle energy loss when using the 66 second delay, resulting in an increase in AFUE of approximately 0.4 AFUE points. Test data on our condensing furnaces show a similar decrease in the heat-up cycle energy loss. When you include the increased amount of condensate formed during the condensate cyclic test, the AFUE increases by approximately 0.7 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 the Coleman Company, Magic Chef Company, Rheem Manufacturing, and the Trane Company. In addition, an interim waiver of this type was recently granted to Lennox Industries. Lastly, the proposed ASHRAE Standard 103-88allows the use of non-adjustable blower ondelays in place of the specified 9o seconds.
Both DOE and NIST were instrumental in the development of Standard 103-88, and suggested it be included so as to address furnaces with fixed blower on-delays. Respectfully, Edward A. Baily,
Vice President, Government &Industry Relations, North American Operations.
