ACTION: Final rule; technical correction.
AGENCY:
On July 10, 2013 the U.S.
Department of Energy (DOE) published
a final rule in the Federal Register that
amended the test procedure for
residential furnaces and boilers (78 FR
41265). Due to drafting errors, that
document incorrectly redesignated
several subsections in section 10 of the
DOE test procedure regulation for those
products in the Code of Federal
Regulations (CFR). This final rule
corrects those errors and updates related
cross-references to reflect the revised
section numbers in section 10.
DATES: Effective Date: August 30, 2013.
The incorporation by reference of
certain publications listed in the
regulations was approved by the
Director of the Federal Register as of
November 10, 1997.

SUPPLEMENTARY INFORMATION:
I. Background
On July 10, 2013, DOE’s Office of
Energy Efficiency and Renewable
Energy published a test procedure final
rule in the Federal Register titled, ‘‘Test
Procedures for Residential Furnaces and
Boilers’’ (hereafter referred to as the
‘‘July 2013 final rule’’). 78 FR 41265.
Since the publication of that final rule,
it has come to DOE’s attention that, due
to a technical oversight, a certain part of
the July 2013 final rule incorrectly
redesignated the numbering of
subsections within section 10 of DOE’s
test procedure regulations for residential
furnaces and boilers found at 10 CFR,
part 430, subpart B, Appendix N,
‘‘Uniform Test Method for Measuring
the Energy Consumption of Furnaces
and Boilers.’’ In addition, the July 2013
final rule did not include instructions to
update the cross-references within
Appendix N to reflect the renumbered
subsections. During the development of
amended test procedure for residential
furnaces and boilers, DOE did not
intend to redesignate the sections as
indicated on page 41272 of the July
2013 final rule, and did intend to
update the cross-references within
Appendix N to reflect the appropriate
section renumbering. Instead, these
incorrect redesignations were the result
of drafting errors in the final rule.
Today’s final rule corrects these errors
by appropriately redesignating the
subsections within section 10 of
Appendix N and updating the internal
cross-references in Appendix N to
reflect the revised subsection
numbering.
II. Need for Correction
As published, the identified
provisions in section 10 of 10 CFR part
430, subpart B, Appendix N will
potentially result in confusion regarding
how to correctly conduct DOE’s
residential furnaces and boilers test
procedure. It was clearly not DOE’s
intention to change or eliminate
additional sections beyond those
explicitly cited for revision. At no place
in the July 2013 final rule (or in the
February 4, 2013 notice of proposed
rulemaking that preceded it (78 FR
7681)) did DOE discuss such
modifications. These were inadvertent
PO 00000
Frm 00001

changes. Because today’s final rule
would simply effectuate the intended
and proper renumbering of the relevant
regulatory provisions without making
substantive changes to those provisions,
the changes addressed in this document
are technical in nature. Accordingly,
DOE finds that there is good cause
under 5 U.S.C. 553(b)(B) to not issue a
separate notice to solicit public
comment on the changes contained in
this document. Issuing a separate notice
to solicit public comment would be
impractical, unnecessary, and contrary
to the public interest.
III. Procedural Requirements
DOE has concluded that the
determinations made pursuant to the
various procedural requirements
applicable to the July 10, 2013 test
procedure final rule remain unchanged
for this final rule technical correction.
These determinations are set forth in the
July 10, 2013 final rule. 78 FR 41265,

10.0 Calculation of derived results from
test measurements. Calculations shall be as
specified in section 11 of ANSI/ASHRAE
103–1993 (incorporated by reference, see
§ 430.3) and the October 24, 1996, Errata
Sheet for ASHRAE 103–1993, except for
sections 11.5.11.1, 11.5.11.2, and appendices
B and C; and as specified in sections 10.1
through 10.11 and Figure 1 of this appendix.
10.1 Annual fuel utilization efficiency.
The annual fuel utilization efficiency (AFUE)
is as defined in sections 11.2.12 (noncondensing systems), 11.3.12 (condensing
systems), 11.4.12 (non-condensing
modulating systems), and 11.5.12
(condensing modulating systems) of ANSI/
ASHRAE 103–1993 (incorporated by
reference, see § 430.3), except for the
definition for the term EffyHS in the defining
equation for AFUE. EffyHS is defined as:
EffyHS = heating seasonal efficiency as
defined in sections 11.2.11 (non-condensing
systems), 11.3.11 (condensing systems),
11.4.11 (non-condensing modulating
systems), and 11.5.11 (condensing
modulating systems) of ANSI/ASHRAE 103–
1993, except that for condensing modulating
systems sections 11.5.11.1 and 11.5.11.2 are
replaced by sections 10.2 and 10.3 of this
appendix. EffyHS is based on the assumptions
that all weatherized warm air furnaces or
boilers are located outdoors, that warm air
furnaces which are not weatherized are
installed as isolated combustion systems, and
that boilers which are not weatherized are
installed indoors.
10.2 Part-Load Efficiency at Reduced Fuel
Input Rate. Calculate the part-load efficiency
at the reduced fuel input rate, EffyU,R, for

Energy Conservation Program for Consumer Products: Test
Procedures for Residential Furnaces and Boilers; Correction
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of

ACTION: Final rule; technical correction.
-----------------------------------------------------------------------
SUMMARY: On July 10, 2013 the U.S. Department of Energy (DOE) published
a final rule in the Federal Register that amended the test procedure
for residential furnaces and boilers (78 FR 41265). Due to drafting
errors, that document incorrectly redesignated several subsections in
section 10 of the DOE test procedure regulation for those products in
the Code of Federal Regulations (CFR). This final rule corrects those
errors and updates related cross-references to reflect the revised
section numbers in section 10.
DATES: Effective Date: August 30, 2013. The incorporation by reference
of certain publications listed in the regulations was approved by the
Director of the Federal Register as of November 10, 1997.

SUPPLEMENTARY INFORMATION:
I. Background
On July 10, 2013, DOE's Office of Energy Efficiency and Renewable
Energy published a test procedure final rule in the Federal Register
titled, ``Test Procedures for Residential Furnaces and Boilers''
(hereafter referred to as the ``July 2013 final rule''). 78 FR 41265.
Since the publication of that final rule, it has come to DOE's
attention that, due to a technical oversight, a certain part of the
July 2013 final rule incorrectly redesignated the numbering of
subsections within section 10 of DOE's test procedure regulations for
residential furnaces and boilers found at 10 CFR, part 430, subpart B,
Appendix N, ``Uniform Test Method for Measuring the Energy Consumption
of Furnaces and Boilers.'' In addition, the July 2013 final rule did
not include instructions to update the cross-references within Appendix
N to reflect the renumbered subsections. During the development of
amended test procedure for residential furnaces and boilers, DOE did
not intend to redesignate the sections as indicated on page 41272 of
the July 2013 final rule, and did intend to update the cross-references
within Appendix N to reflect the appropriate section renumbering.
Instead, these incorrect redesignations were the result of drafting
errors in the final rule. Today's final rule corrects these errors by
appropriately redesignating the subsections within section 10 of
Appendix N and updating the internal cross-references in Appendix N to
reflect the revised subsection numbering.
II. Need for Correction
As published, the identified provisions in section 10 of 10 CFR
part 430, subpart B, Appendix N will potentially result in confusion
regarding how to correctly conduct DOE's residential furnaces and
boilers test procedure. It was clearly not DOE's intention to change or
eliminate additional sections beyond those explicitly cited for
revision. At no place in the July 2013 final rule (or in the February
4, 2013 notice of proposed rulemaking that preceded it (78 FR 7681))
did DOE discuss such modifications. These were inadvertent changes.
Because today's final rule would simply effectuate the intended and
proper renumbering of the relevant regulatory provisions without making
substantive changes to those provisions, the changes addressed in this
document are technical in nature. Accordingly, DOE finds that there is
good cause under 5 U.S.C. 553(b)(B) to not issue a separate notice to
solicit public comment on the changes contained in this document.
Issuing a separate notice to solicit public comment would be
impractical, unnecessary, and contrary to the public interest.
III. Procedural Requirements
DOE has concluded that the determinations made pursuant to the
various procedural requirements applicable to the July 10, 2013 test
procedure final rule remain unchanged for this final rule technical
correction. These determinations are set forth in the July 10, 2013
final rule. 78 FR 41265, 41269-41272.

2. Appendix N to subpart B of part 430 is amended by revising the
introductory text after the appendix heading and sections 10.0 through
10.11 to read as follows:
[[Page 53626]]
Appendix N to Subpart B of Part 430--Uniform Test Method for Measuring
the Energy Consumption of Furnaces and Boilers
Note: The procedures and calculations that refer to off mode
energy consumption (i.e., sections 8.6 and 10.11 of this appendix N)
need not be performed to determine compliance with energy
conservation standards for furnaces and boilers at this time.
However, any representation related to standby mode and off mode
energy consumption of these products made after July 1, 2013 must be
based upon results generated under this test procedure, consistent
with the requirements of 42 U.S.C. 6293(c)(2). For furnaces
manufactured on or after May 1, 2013, compliance with the applicable
provisions of this test procedure is required in order to determine
compliance with energy conservation standards. For boilers, the
statute requires that after July 1, 2010, any adopted energy
conservation standard shall address standby mode and off mode energy
consumption for these products, and upon the compliance date for
such standards, compliance with the applicable provisions of this
test procedure will be required.

10.0 Calculation of derived results from test measurements.
Calculations shall be as specified in section 11 of ANSI/ASHRAE 103-
1993 (incorporated by reference, see Sec. 430.3) and the October
24, 1996, Errata Sheet for ASHRAE 103-1993, except for sections
11.5.11.1, 11.5.11.2, and appendices B and C; and as specified in
sections 10.1 through 10.11 and Figure 1 of this appendix.
10.1 Annual fuel utilization efficiency. The annual fuel
utilization efficiency (AFUE) is as defined in sections 11.2.12
(non-condensing systems), 11.3.12 (condensing systems), 11.4.12
(non-condensing modulating systems), and 11.5.12 (condensing
modulating systems) of ANSI/ASHRAE 103-1993 (incorporated by
reference, see Sec. 430.3), except for the definition for the term
EffyHS in the defining equation for AFUE.
EffyHS is defined as:
EffyHS = heating seasonal efficiency as defined in
sections 11.2.11 (non-condensing systems), 11.3.11 (condensing
systems), 11.4.11 (non-condensing modulating systems), and 11.5.11
(condensing modulating systems) of ANSI/ASHRAE 103-1993, except that
for condensing modulating systems sections 11.5.11.1 and 11.5.11.2
are replaced by sections 10.2 and 10.3 of this appendix.
EffyHS is based on the assumptions that all weatherized
warm air furnaces or boilers are located outdoors, that warm air
furnaces which are not weatherized are installed as isolated
combustion systems, and that boilers which are not weatherized are
installed indoors.
10.2 Part-Load Efficiency at Reduced Fuel Input Rate. Calculate
the part-load efficiency at the reduced fuel input rate,
