Energy Conservation Program for Consumer Products: Granting of 
the Application for Interim Waiver and Publishing of the Petition for 
Waiver of DOE Furnace Test Procedures From Rheem Manufacturing Company

AGENCY: Office of Energy Efficiency and Renewable Energy.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: Today's notice publishes a letter granting an Interim Waiver 
to Rheem Manufacturing Company (Rheem) from the existing Department of 
Energy (DOE) test procedure regarding blower time delay for the 
company's GRA upflow, and GSA downflow condensing gas furnaces.

    Today's notice also publishes a ``Petition for Waiver'' from Rheem. 
Rheem's Petition for Waiver requests DOE to grant relief from the DOE 
furnace test procedure relating to the blower time delay specification. 
Rheem seeks to test using a blower delay time of 20 seconds for its GRA 
upflow, and GSA downflow condensing gas furnaces instead of the 
specified 1.5-minute delay between burner on-time and blower on-time. 
The Department is soliciting comments, data, and information respecting 
the Petition for Waiver.

DATES: DOE will accept comments, data, and information not later than 
October 17, 1994.

ADDRESSES: Written comments and statements shall be sent to: Department 
of Energy, Office of Energy Efficiency and Renewable Energy, Case No.

SUPPLEMENTARY Information: 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. 3266, the National Appliance Energy 
Conservation Act of 1987 (NAECA), Public Law 100-12, the National 
Appliance Energy Conservation Amendments of 1988 (NAECA 1988), Public 
Law 100-357, and the Energy Policy Act of 1992 (EPAct), Public Law 102-
486, 106 Stat. 2776, 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.
    The Department 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 Energy Efficiency 
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 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 the waiver.
    The Interim Waiver provisions added by the 1986 amendment allow the 
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 determines that 
it would be desirable for public policy reasons to grant immediate 
relief pending a determination on the Petition for Waiver. An Interim 
Waiver remains in effect for a period of 180 days or until DOE issues 
its determination on the Petition for Waiver, whichever is sooner, and 
may be extended for an additional 180 days, if necessary.
    On July 15, 1994, Rheem filed an Application for Interim Waiver and 
a Petition for 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 GRA upflow, and GSA downflow condensing gas furnaces. Rheem 
states that the 20-second delay is indicative of how these furnaces 
actually operate. Such a delay results in an average of approximately 
3.0 percent improvement in energy efficiency. Since current DOE test 
procedures do not address this variable blower time delay, Rheem asks 
that the Interim Waiver be granted.
    Rheem's Petition for Waiver also requests DOE to grant relief from 
the DOE furnace test procedure relating to the above specification.
    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

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, 57 FR 54230, November 17, 1992, and 59 FR 
30575, June 14, 1994; 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, and 59 FR 30578, 
June 14, 1994. 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 GRA upflow, and GSA downflow condensing gas furnaces. 
Pursuant to paragraph (e) of Sec. 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 Sec. 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.

Mr. Daniel J. Canclini,
Vice President-Product Development and Research Engineering, Rheem 
Manufacturing Company, P.O. Box 17010, Fort Smith, AR 72917-7010.

    Dear Mr. Canclini: This is in response to your July 15, 1994, 
Application for Interim Waiver and Petition for Waiver from the 
Department of Energy (DOE) test procedure regarding blower time 
delay for Rheem Manufacturing Company (Rheem) GRA upflow, and GSA 
downflow condensing gas furnaces.
    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, 57 FR 53733, November 12, 1992, and 59 FR 
30578, June 14, 1994. Thus, it appears likely that the Petition for 
Waiver will be granted for blower time delay.
    Rheem's Application for Interim Waiver does not provide 
sufficient information to evaluate what, if any, economic impact or 
competitive disadvantage Rheem 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, Rheem's Application for an Interim Waiver from the 
DOE test procedure for its GRA upflow, and GSA downflow condensing 
gas furnaces regarding blower time delay is granted.
    Rheem shall be permitted to test its GRA upflow, and GSA 
downflow condensing gas 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/ASHRAE 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-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; or (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 temperature. During the heat-up test for oil-
fueled furnaces, maintain the draft in the flue pipe within 
 0.01 inch of water column 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 removed 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,
Christine A. Ervin,
Assistant Secretary, Energy Efficiency and Renewable Energy.

July 15, 1994.
Mr. Cyrus Nasseri,
Assistant Secretary, Conservation and Renewable Energy, United 
States Department of Energy, 1000 Independence Avenue SW., 
Washington, DC 20585.

    Dear Mr. Nasseri: This is a petition for waiver and application 
for interim waiver submitted pursuant to title 10 CFR Part 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. Rheem is 
requesting authorization to use a 20 second delay instead of 1.5 
minutes for our Series (-)GRA upflow and (-)GSA downflow condensing 
type 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 3%. Rheem is of the 
opinion that this reduction in energy is a worthwhile savings.
    Rheem has most recently been granted previous waivers regarding 
blower on time to be used in the efficiency calculations for our (-
)GED and (-)GKC series condensing furnaces and (-)GDG, (-)GVH, (-
)GPH, (-)GLH 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 9.51.2.2 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.
