DEPARTMENT OF ENERGY
Office of Energy Efficiency and Renewable Energy
Energy Conservation Program for Consumer Products: Granting of
the Application for Interim Waiver and Publishing of the Petition for
Waiver of Thermo Products Inc. From the DOE Furnace Test Procedure.
(Case No. F-083)
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: Today's notice grants an Interim Waiver to Thermo Products
Inc. (Thermo Products) from the existing Department of Energy (DOE or
Department) test procedure regarding blower time delay for the
company's CHA-upflow and CCA-downflow condensing gas furnaces.
Today's notice also publishes a ``Petition for Waiver'' from Thermo
Products. Thermo Products Petition for Waiver requests DOE to grant
relief from the DOE furnace test procedure relating to the blower time
delay specification. Thermo Products seeks to test using a blower delay
time of 45 seconds for its CHA-upflow and CCA-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
February 29, 1996.
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, as amended (EPCA), 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 Title 10 CFR Part 430,
Subpart B.
The Department amended the test procedure rules to provide for a
waiver process by adding Section 430.27 to Title 10 CFR Part 430. 45 FR
64108, September 26, 1980. Subsequently, DOE amended the 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. Title 10 CFR Part 430,
Section 430.27(a)(2).
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.
An Interim Waiver will be granted if 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. Title 10 CFR
Part 430, Section 430.27(g). An Interim Waiver remains in effect for a
period of 180 days or until DOE issues its determination on the
Petition for
[[Page 3024]]
Waiver, whichever is sooner, and may be extended for an additional 180
days, if necessary.
On November 29, 1995, Thermo Products filed an Application for
Interim Waiver and a Petition for Waiver regarding blower time delay.
Thermo Products 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, Thermo
Products requests the allowance to test using a 45-second blower time
delay when testing its CHA-upflow and CCA-downflow condensing gas
furnaces. Thermo Products states that the 45-second delay is indicative
of how these furnaces actually operate. Such a delay results in an
increase in AFUE improvement of up to 2.0 percent. Since current DOE
test procedures do not address this variable blower time delay, Thermo
Products 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 Petitions for Waiver for this type of time blower delay
control have been granted by DOE to Coleman Company, 50 FR 2710,

Thus, it appears likely that this Petition for Waiver for blower
time delay will be granted. 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 Thermo Products an
Interim Waiver for its CHA-upflow and CCA-downflow condensing gas
furnaces. Thermo Products shall be permitted to test its CHA-upflow and
CCA-downflow condensing gas furnaces on the basis of the test
procedures specified in Title 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
-
.
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.
Thermo Products's Petition for Waiver requests DOE to grant relief
from the DOE furnace test procedure relating to the blower time delay
specification. Thermo Products seeks to test using a blower delay time
of 45 seconds for its CHA-upflow and CCA-downflow condensing gas
furnaces instead of the specified 1.5-minute delay between burner on-
time and blower on-time. Pursuant to paragraph (b) of Title 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.

Subject: Petition for Waiver and Application for Interim Waiver
[[Page 3025]]
Gentlemen: This is a Petition for Waiver and Application for
Interim Waiver which are submitted pursuant to Title 10 CFR 430.27.
Waiver is requested from Test Procedures for Measuring the Energy
Consumption of Furnace found in Appendix N to Subpart B of Part 430.
The test procedure requires a 1.5 minute delay between burner
and blower start-up. Thermo Products requests a waiver from the
specified 1.5 minute delay and requests approval to use a 45-second
delay for our Series CHA- upflow and CCA- downflow condensing type
residential gas fired furnaces.
An electronic fan control is being used on these products that
incorporate a fixed timing.
Current test procedures do not credit Thermo Products for the
energy savings associated with the shorter blower timing. The
shorter timed on fan delay reduces flue losses therefor increasing
furnace efficiency. Test data for these furnaces utilizing a 45-
second timing indicates an increase in AFUE up to 2%. Confidential
supporting test data is available upon request.
Thermo Products is confident that this Waiver will be granted,
as several other manufacturers of gas furnaces received DOE granted
waivers such as Carrier, Lennox Industries, Inter-City Products,
Amana, Rheem Manufacturing and others based on timed blower
operation.
Manufacturers that domestically market similar products are
being sent a copy of this Petition for Waiver and Application for
Interim Waiver.
Sincerely,
Everett E. James,
Director of Engineering.
