[Case No. F-080]
Energy Conservation Program for Consumer Products: Granting of
the Application for Interim Waiver and Publishing of the Petition for
Waiver of the Trane Company From the DOE Furnace Test Procedure
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: Today's notice publishes a letter granting an Interim Waiver
to The Trane Company (Trane) from the existing Department of Energy
(DOE or Department) test procedure regarding blower time delay for the
company's TUD-C/AUD-C, TDD-C/ADD-C, TUD-R/AUD-R, TDD-R/ADD-R, TUD-R-V/
AUD-R-V, TDD-R-V/ADD-R-V, TUY-R-V/AUY-R-V, and TDY-R-V/ADY-R-V central
furnaces.
Today's notice also publishes a ``Petition for Waiver'' from Trane.
Trane's Petition for Waiver requests DOE to grant relief from the DOE
furnace test procedure relating to the blower time delay specification.
Trane seeks to test using a blower delay time of 45 seconds for its
TUD-C/AUD-C, TDD-C/ADD-C, TUD-R/AUD-R, TDD-R-ADD-R, TUD-R-V/AUD-R-V,
TDD-R-V/ADD-R-V, TUY-R-V/AUY-R-V, and TDY-R-V/ADY-R-V central 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
November 13, 1995.

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
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 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 August 11, 1995, Trane filed an Application for Interim Waiver
and a Petition for Waiver regarding blower time delay. Trane'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, Trane requests the
allowance to test using a 45-second blower time delay when testing its
TUD-3C/AUD-C, TDD-C/ADD-C, TUD-R/AUD-R, TDD-R/ADD-R, TUD-R-V/AUD-R-V,
TDD-R-V/ADD-R-V, TUY-R-V/AUY-R-V, and TDY R-V/ADY-R-V central furnaces.
Trane states that the 45-second delay is indicative of how these
furnaces actually operate. Such a delay results in an overall furnace
AFUE of approximately 1.0 percent point improvement. Since current DOE
test procedures do not address this variable blower time delay, Trane
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,

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,

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, 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 59 FR 46968, September 13, 1994; Bard
Manufacturing Company, 57 FR 53733, November 12, 1992, and 59 FR 30578,
June 14, 1994; and York International Corporation, 59 FR 46969,
September 13, 1994, and 60 FR 100, January 3, 1995. 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 Trane an Interim
Waiver for its TUD-C/AUD-C, TDD-C/ADD-C, TUD-R/AUD-R, TDD-R/ADD-R, TUD-
R-V/AUD-R-V, TDD-R-V/ADD-R-V, TUY-R-V/AUY-R-V, TDY-R-V/ADY-R-V, and
TDY-R-V/ADY-R-V central furnaces. Pursuant to paragraph (e) of
[[Page 53356]]
Section 430.27 of the Code of Federal Regulations Part 430, the
following letter granting the Application for Interim Waiver to Trane
was issued.
Trane's Petition for Waiver requested DOE to grant relief from the
DOE furnace test procedure relating to the blower time delay
specification. Trane seeks to test using a blower delay time of 45
seconds for its TUD-C/AUD-C, TDD-C/ADD-C, TUD-R/AUD-R, TDD-R/ADD-R,
TUD-R-V/AUD-R-V, TDD-R-V/ADD-R-V, TUY-R-V/AUY-R-V, TDY-R-V/ADY-R-V, and
TDY-R-V/ADY-R-V central furnaces instead of the specified 1.5-minute
delay between burner on-time and blower on-time. Pursuant to paragraph
(b) of 10 CFR Part 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.

Dear Mr. Ahn: This is in response to your August 11, 1995,
Application for Interim Waiver and Petition for Waiver from the
Department of Energy (DOE or Department) test procedure regarding
blower time delay for The Trane Company (Trane) TUD-C/AUD-C, TDD-C/
ADD-C, TUD-R/AUD-R, TDD-R/ADD-R, TUD-R-V/AUD-R-V, TDD-R-V/ADD-R-V,
TUY-R-V/AUY-R-V, and TDY-R-V/ADY-R-V central furnaces.
Previous waivers for this type of timed blower delay control

November 12, 1992, and 59 FR 30578, June 14, 1994; and York
International Corporation, 59 FR 46969, September 13, 1994, and 60
FR 100, January 3, 1995. Thus, it appears likely that the Petition
for Waiver will be granted for blower time delay.
Trane's Application for Interim Waiver does not provide
sufficient information to evaluate what, if any, economic impact or
competitive disadvantage Trane 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, Trane's Application for an Interim Waiver from the
DOE test procedure for its TUD-C/AUD-C, TDD-C/ADD-C, TUD-R/AUD-R,
TDD-R/ADD-R, TUD-R-V/AUD-R-V, TDD-R-V/ADD-R-V, TUY-R-V/AUY-R-V, and
TDY-R-V/ADY-R-V central furnaces regarding blower time delay is
granted.
Trane shall be permitted to test its TUD-C/AUD-C, TDD-C/ADD-C,
TUD-R/AUD-R, TDD-R/ADD-R, TUD-R-V/AUD-R-V, TDD-R-V/ADD-R-V, TUY-R-V/
AUY-R-V, and TDY-R-V/ADY-R-V central 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 temperatures. 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.
The Department is publishing in the Federal Register the
Petition for Waiver in its entirely. The Petition contains no
confidential information. The Department is soliciting comments,
data, and information respecting the Petition.
Sincerely,
Christine A. Ervin,
Assistant Secretary, Energy Efficiency and Renewable Energy.

Hon. Christine Ervin,
Assistant Secretary, Energy Efficiency and Renewable Energy of DOE,
1000 Independence Ave., S.W., Washington, DC 20585.
Dear Hon. Ervin: This is to submit an Application for Interim
Waiver and Petition for Waiver from the Department of Energy (DOE)
test procedure, prescribed in 10 CFR Part 430, Subpart B, Appendix N
for furnace products. The Waiver is regarding blower on-time delay
on behalf of The Trane Co./American Standard Inc., in accordance
with Title 10 CFR, Part 430.27. In addition to the central heating
furnace series, to which you have granted a waiver to use 45 seconds
blower on-time delay in lieu of 1.5 minute, as specified in the test
procedures, we now have new furnace series which also require the
use of 45 seconds time delay instead of 1.5 minutes. They are: TUD-
C/AUD-C, TDD-C/ADD-C, TUD-R/AUD-R, TDD-R/ADD-R, TUD-R-V/AUD-R-V,
TDD-R-V/ADD-R-V, TUY-R-Y/AUY-R-V, and TDY-R-V/ADY-R-V.
The above furnaces are equipped with a fan on-time control with
a fixed time of 45 seconds. The current DOE test procedures do not
credit Trane/American Standard for additional energy savings that
are realized
[[Page 53357]]
when the shorter blower on-time 45 second is utilized. Test data for
each model series indicates an average of 1% AFUE increase when the
45 second on-time delay is used. Copies of confidential test data
supporting these energy savings will be forwarded to you upon
request.
Trane/American Standard Inc. is confident that this petition for
Waiver will be granted, and therefore, requests an Interim Waiver
until the forthcoming final rule.
To this data, there are numerous central forced air furnace
manufacturers to which similar waivers have been granted. Also the
proposed ASHRAE 103.93 test standards under consideration by DOE
covers the test requirement for fan on-time delay related to the
Petition for Waiver.
Manufacturers that domestically market similar products have
been sent a copy of the Petition and Application for Interim Waiver.
For your reference, attached is a copy of the letter from James
T. VerShaw, dated August 27, 1993, and the letter from Mr. Frank M.
Stewart, Jr., with which the previous application for an Interim
Waiver was granted.
Sincerely,
Hongsik Ahn,
Sr. Principal Engineer HA/nh Enclosures.
August 27, 1993.
Assistant Secretary, Conservation and Renewable Resources,
United States Department of Energy, 1000 Independence Ave. SW.,
Washington, D.C. 20585.
Gentlemen: 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 found in
appendix N to Subpart B of Part 430.
The current procedure requires a 1.5 minute delay between burner
and supply air blower startup. Trane is requesting the use of 45
seconds instead of 1.5 minutes when testing the following central
furnace families incorporating a timed fan control with a fixed time
of 45 seconds: TUC-C/AUC-A, TDC-C/ADC-C, TUX-C/AUX-C, TDX-C/ADX-C,
TUE-A, TDE-A, FUA-A, and FCA-A. The current procedure does not
credit Trane for additional energy savings that are realized when a
shorter blower on time is utilized. Test data for each model series
indicates an average of 1% AFUE increase when a 45 second timed on
delay is used. Copies of confidential test data confirming these
energy savings will be forwarded to you upon request.
Trane is confident that this petition for Waiver will be
granted, and therefore, requests an Interim Waiver until the final
ruling is made. Similar waivers have been granted to Evcon, Rheem
Manufacturing, Carrier, Inter-City Products, and Lennox Industries.
Also, the proposed ASHRAE 103-88 currently under consideration by
DOE contains the coverage requested in the Petition for Waiver.
Manufacturers that domestically market similar products have
been sent a copy of the Petition for Waiver and Application for
Interim Waiver.
Sincerely,

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.
Trane's Application for Interim Waiver does not provide
sufficient information to evaluate what, if any, economic impact or
competitive disadvantage Trane 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, Trane's Application for an Interim Waiver from the
DOE test procedure for its TUC-C/AUC-A, TDC-C/ADC-C, TUX-C/AUX-C,
TDX-C/ADX-C, TUE-A, TDE-A, FUA-A, and FCA-A central furnaces
regarding blower time delay is granted.
Trane shall be permitted to test its TUC-C/AUC-A, TDC-C/ADC-C,
TUX-C/AUX-C, TDX-C/ADX-C, TUE-A, FUA-A, and FCA-A central 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 temperatures. 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,
Frank M. Stewart, Jr.,
Acting Assistant Secretary Energy Efficiency and Renewable Energy.
