SUPPLEMENTARY INFORMATION: In accordance with 10 CFR 430.27(g), notice
is hereby given of the issuance of the Decision and Order as set out
below. In the Decision and Order, Carrier has been granted a Waiver for
its 48HJ, 48HM, 48TJ/580D, 48SS/588A, and 48SX/589A induced draft roof-
top furnaces, permitting the company to use an alternate test method in
determining AFUE.

Decision and Order
In the Matter of: Carrier Corporation. (Case No. F-065)
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. 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 to create a waiver process. 45 FR 64108, September 26, 1980.
Thereafter, DOE further amended its 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.
Carrier filed a ``Petition for Waiver,'' dated October 13, 1993, in
accordance with Sec. 430.27 of 10 CFR part 430. The Department
published in the Federal Register on December 27, 1993, Carrier's
petition and solicited comments, data and information respecting the
petition. 58 FR 68400. Carrier also filed an ``Application for Interim
Waiver'' under section 430.27(g) which DOE granted on December 17,
1993. 58 FR 68400, December 27, 1993.
No comments were received concerning either the ``Petition for
Waiver'' or the ``Interim Waiver.'' The Department consulted with The
Federal Trade Commission (FTC) concerning the Carrier Petition. The FTC
did not have any objections to the issuance of the waiver to Carrier.
Assertions and Determinations
Carrier's Petition seeks a waiver from the DOE test provisions that
require a 1.5-minute time delay between the ignition of the burner and
the starting of the circulating air blower. Carrier requests the
allowance to test using a 45-second blower time delay when testing its
48HJ, 48HM, 48TJ/580D, 48SS/588A, and 48SX/589A induced draft roof-top
furnaces. Carrier states that since the 45-second delay is indicative
of how these models actually operate and since such a delay results in
an improvement in efficiency of approximately 0.6 percent, the petition
should be granted.
Under specific circumstances, the DOE test procedure contains
exceptions which allow testing with blower delay times of less than the
prescribed 1.5 minute delay. Carrier indicates that it is unable to
take advantage of any of these exceptions for its 48HJ, 48HM, 48TJ/
580D, 48SS/588A, and 48SX/589A induced draft roof-top furnaces.
Since the blower controls incorporated on the Carrier 48HJ, 48HM,
48TJ/580D, 48SS/588A, and 48SX/589A induced draft roof-top furnaces are
designed to impose a 45-second blower delay in every instance of start
up, and since the current provisions do not specifically address this
type of control, DOE agrees that a waiver should be granted to allow
the 45-second blower time delay when testing the Carrier 48HJ, 48HM,
48TJ/580D, 48SS/588A, and 48SX/589A induced draft roof-top furnaces.
Accordingly, with regard to testing the above induced draft roof-top
furnaces, today's Decision and Order exempts Carrier from the existing
provisions regarding blower controls and allows testing with the 45-
second delay.
It is, therefore, ordered that: (1) The ``Petition for Waiver''
filed by Carrier Corporation. (Case No. F-065) is hereby granted as set
forth in paragraph (2) below, subject to the provisions of paragraphs
(3), (4), and (5).
(2) Notwithstanding any contrary provisions of Appendix N of 10 CFR
part 430, Subpart B, Carrier Corporation, shall be permitted to test
its 48HJ, 48HM, 48TJ/580D, 48SS/588A, and 48SX/589A induced draft roof-
top furnaces on the basis of the test procedure specified in 10 CFR
part 430, with modifications set forth below:
(i) Section 3.0 of 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 Standard 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 to Appendix N as follows:
3.10 Gas- and Oil-Fueled Central Furnaces. The following paragraph
is in lieu of the requirement specified in section 9.3.1 of ANSI/ASHRAE
Standard 103-82. 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 circulating 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 stopwatch. 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.
(iii) With the exception of the modifications set forth above,
Carrier Corporation shall comply in all respects with the test
procedures specified in Appendix N of 10 CFR Part 430, Subpart B.
(3) The Waiver shall remain in effect from the date of issuance of
this Order until DOE prescribes final test procedures appropriate to
the 48HJ, 48HM, 48TJ/580D, 48SS/588A, and 48SX/589A induced draft roof-
top furnaces manufactured by Carrier Corporation.
(4) This Waiver is based upon the presumed validity of statements,
allegations, and documentary materials submitted by the petitioner.
This Waiver may be revoked or modified at any time upon a determination
that the factual basis underlying the petition is incorrect.
(5) Effective March 21, 1994, this Waiver supersedes the Interim
Waiver granted the Carrier Corporation on December 17, 1993. 58 FR
68400, December 27, 1993 (Case No. F-065).
Issued In Washington, DC, March 21, 1994.
