SUPPLEMENTARY INFORMATION: In a
petition received July 21, 2015, Johnston
requested that the U.S. Department of
Energy (‘‘DOE’’) grant a waiver to
certain models of larger commercial
package boilers that cannot be tested
under the existing DOE test procedure.
The models of commercial packaged
boilers at issue are models with higher
input capacities that typically require
higher steam pressure and alternative
instrumentation due to the large
quantities of fluids being measured.
I. Background and Authority
Title III, Part C of the Energy Policy
and Conservation Act of 1975 (EPCA),
as amended (42 U.S.C. 6311 et seq.),
established the Energy Conservation
Program for certain industrial
equipment, which includes commercial
packaged boilers.1 Part C specifically
includes definitions (42 U.S.C. 6311),
energy conservation standards (42 U.S.C
6313), test procedures (42 U.S.C. 6314),
labeling provisions (42 U.S.C. 6315),
and the authority to require information
and reports from manufacturers (42
U.S.C. 6316). Part C authorizes the
Secretary of Energy (the Secretary) to
prescribe test procedures that are
reasonably designed to produce results
that measure energy efficiency, energy
use, and estimated annual operating
costs, and that are not unduly
burdensome to conduct. (42 U.S.C.
6314(a)(2)) With respect to commercial
packaged boilers, Part C requires DOE to
use industry test procedures developed
or recognized by the Air-Conditioning,
Heating, and Refrigeration Institute
(AHRI) or the American Society of
Heating, Refrigerating, and AirConditioning Engineers (ASHRAE), as
referenced in ASHRAE/IES 2 Standard
90.1, ‘‘Energy Standard for Buildings
Except Low-Rise Residential Buildings.’’
(42 U.S.C. 6314(a)(4)(A)) Further, if such
an industry test procedure is amended,
DOE is required to amend its test
procedure to be consistent with the
amended industry test procedure,
unless it determines, by rule published
1 For editorial reasons, upon codification in the
U.S. Code, Part C was re-designated Part A–1.

in the Federal Register and supported
by clear and convincing evidence, that
the amended test procedure would be
unduly burdensome to conduct or
would not produce test results that
reflect the energy efficiency, energy use,
and estimated operating costs of that
equipment during a representative
average use cycle. (42 U.S.C.
6314(a)(4)(B)). The test procedure for
commercial packaged boilers is
contained in 10 CFR part 431, subpart
E.
DOE’s regulations for covered
products and equipment permit a
person to seek a waiver from the test
procedure requirements for covered
commercial equipment if at least one of
the following conditions is met: (1) The
petitioner’s basic model contains one or
more design characteristics that prevent
testing according to the prescribed test
procedures; or (2) 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. 10 CFR 431.401(a)(1).
A petitioner must include in its petition
any alternate test procedures known to
the petitioner to evaluate the basic
model in a manner representative of its
energy consumption. 10 CFR
431.401(b)(1)(iii).
DOE may grant a waiver subject to
conditions, including adherence to
alternate test procedures. 10 CFR
431.401(f)(2). As soon as practicable
after the granting of any waiver, DOE
will publish in the Federal Register a
notice of proposed rulemaking to amend
its regulations so as to eliminate any
need for the continuation of such
waiver. As soon thereafter as
practicable, DOE will publish in the
Federal Register a final rule. 10 CFR
431.401(l).

II. Petition for Waiver of Test Procedure
On July 21, 2015, Johnston submitted
a petition for waiver from the DOE test
procedure for certain basic models of its
commercial packaged boilers. The DOE
test procedure for commercial packaged
boilers is set forth at 10 CFR 431.86 and
incorporates by reference Hydronics
Institute (HI) BTS–2000, ‘‘Method to
Determine Efficiency of Commercial
Space Heating Boilers’’ (BTS–2000).
According to Johnston, there are
several issues that make BTS–2000
incompatible with larger commercial
packaged boilers, including those
identified in its petition for waiver.
Johnston stated that the requirements to
use test conditions specified in BTS–
2000 and the instrumentation
requirements are outdated. Specifically,
VerDate Sep<11>2014
20:48 Jun 10, 2016
Jkt 238001
Johnston indicated the following
regarding the test conditions:
• The 0 to 2 psig test pressure for
steam boilers may be adequate for
residential and small commercial (cast
iron) boilers sized [commercial
packaged] boilers, however such steam
pressures are not compatible with large
[commercial packaged] boilers as it will
cause water carryover in large
quantities, and an inability to meet
design water flow rates and firing rates;
• Typically test steam pressures in
the range of 10 to 12 psig are required;
and
• Test temperatures defined for hot
water [commercial packaged] boilers
cause thermal shock problems in large
[commercial packaged] boilers.
Johnston also indicated the following
regarding the instrumentation chart in
Table 1 of section 6.0, ‘‘Instruments,’’ of
BTS–2000:
• Steam pressure cannot be measured
by mercury manometer as the use of
mercury in instruments and controls is
banned; the correct instrument is a
Bourdon Tube Gauge for pressures of 0
to 30 psig;
• Large boilers typically fire into a
positive pressure combustion chamber,
thus gas pressure, firebox pressure and
vent/flue pressure instruments all need
to reflect this;
• The use of scales to measure water/
condensate/moisture flow rates is
incompatible with the volume of these
fluids being used or generated by large
[commercial packaged] boilers; water
flow meters should be used and in the
case of moisture content, current
practice is to use a throttling
calorimeter;
• The measurement of carbon dioxide
as a means of calculating excess air or
oxygen is considered obsolete in the
large [commercial packaged] boiler
industry; direct measurement of excess
oxygen is the preferred method as
modern oxygen meters can easily be
calibrated against the oxygen in the
ambient air;
• Carbon Monoxide levels are no
longer measured as a percentage; the
current preferred unit is parts per
million (ppm).
To address these concerns, Johnston
proposes to use the newly published
American National Standards Institute
(ANSI)/Air-Conditioning, Heating, and
Refrigeration Institute (AHRI) 1500–
2015, ‘‘Standard for Performance Rating
of Commercial Space Heating Boilers’’
(ANSI/AHRI Standard 1500–2015) in
place of BTS–2000. AHRI developed
ANSI/AHRI Standard 1500–2015 as a
replacement for BTS–2000 in order to
make the test procedure suitable for use
with larger commercial packaged
PO 00000

boilers, as well as improve and clarify
the test method. Johnston claims that
use of this ANSI/AHRI Standard 1500–
2015 is necessary as it is compatible
with the size of commercial packaged
boilers they manufacture.
Additionally, for the large commercial
packaged boilers capable of supplying
either steam or hot water identified in
this petition, Johnston requests that,
when determining the combustion
efficiency in hot water mode based on
testing in steam mode only, the
combustion efficiency rating be
determined based on an adjusted
combustion efficiency. Johnston
requests that an adjustment be made to
the measured stack temperature to be
used in calculating combustion
efficiency based on the relative
difference between the flue gas
temperature and the bulk fluid
temperature when operating in steam
mode as opposed to hot water using the
following relationship:
Tstack, hw = (Tstack, steam ¥ Tsat) + Tbulk, hw
where Tstack, hw is the stack temperature
to be used to determine the combustion
efficiency in hot water mode, Tstack, steam
is the measured stack temperature when
testing on steam, Tsat is the saturation
temperature of steam at the test
pressure, and Tbulk, hw is the temperature
of the outlet water when testing in hot
water mode and is equal to 180 °F.
According to Johnston, using this
adjusted stack temperature to calculate
combustion efficiency is a more
accurate representation of the actual
efficiency when operating as a hot water
commercial packaged boiler than simply
using combustion efficiency value for
steam mode.
Johnston also requests to use the
vertical stack arrangement shown on
their ‘‘Drawing #327A0040 Johnston
Boiler General Arrangement D.O.E.
Efficiency Test (attachment B).’’ DOE’s
existing test procedure incorporates
section 7.0 ‘‘Apparatus’’ of BTS–2000
with respect to test setup including flue
connection requirements. (DOE notes
that the term ‘‘flue,’’ not ‘‘stack,’’ is used
throughout its test procedure
regulations as well as BTS–2000). The
flue requirements differ depending on
the characteristics of the commercial
packaged boiler, including:
• Whether the unit is oil-fired or gasfired, and if gas-fired;
• Whether the unit is direct vent;
• Whether the unit has an input
rating of more than 400,000 Btu/h;
• Whether the unit is discharges vent
gases horizontally or vertically; and
• Whether the unit is condensing.
According to Johnston, the large
volume of flue gas in relation to the flue

diameter results in relatively high
velocities and therefore creates
turbulence. Johnston indicates that this
straight stack arrangement is shown in
their operating manual and in the
American Boiler Manufacturer
Association’s (ABMA) ‘‘Packaged Boiler
Engineering Manual.’’ DOE requests
comment on how turbulence affects
measured efficiency under the current
test procedure, and how use of the
vertical stack arrangement shown in the
drawing provided by Johnston would
prevent turbulence.
In addition, Johnston stated that
ANSI/AHRI Standard 1500–2015 does
not clarify whether there is an upper
limit for fuel input rate to which the
standard applies. However, the scope of
ANSI/AHRI Standard 1500–2015 is
identified as ‘‘commercial space heating
boilers’’ in section 1.1. (Note: The term
‘‘commercial space heating boiler’’ is
not defined in ANSI/AHRI Standard
1500–2015.) Johnston suggested that the
upper fuel input rate limit be
established at 12,500,000 Btu/hr.
Johnston stated that the two major safety
standards for the industry are American
Society of Mechanical Engineers
(ASME) CSD–1 Controls and Safety
Devices for Automatically Fired Boilers
(ASME CSD–1) and National Fire
Protection Association (NFPA)–85–2015
Boiler and Combustion Systems Hazard
Code (NFPA–85). Johnston further
indicated that the scope of ASME CSD–
1 is for commercial boilers with inputs
from 400,000 to 12,500,000 Btu/hr and
the scope for NFPA–85 is for industrial
boilers over 12,500,000 Btu/hr. DOE
notes that neither the existing DOE test
procedure or energy standards establish
an upper limit in terms of fuel input rate
for which they apply. Consequently,
DOE is declining to consider Johnston’s
request for an upper limit for the fuel
input rate which would limit the scope
of applicability of the test procedure in
this proceeding.
DOE notes that it has published a
notice of proposed rulemaking (NOPR)
to amend its test procedure for
commercial packaged boilers prescribed
in 10 CFR part 431 subpart E (March
2016 CPB TP NOPR). 81 FR 14641 (Mar.
17, 2016). The proposed amended test
procedure addresses, among other
changes, most of the issues raised in this
waiver request by incorporating by
reference ANSI/AHRI Standard 1500–
2015 as a replacement for BTS–2000 in
the DOE test procedure for commercial
packaged boilers. In addition to
adopting ANSI/AHRI Standard 1500–
2015 as a replacement for BTS–2000,
DOE further proposes several
modifications to its test procedure that
are not captured in ANSI/AHRI
VerDate Sep<11>2014
20:48 Jun 10, 2016
Jkt 238001
Standard 1500–2015 in order to improve
repeatability, add clarification, and
accommodate testing of some
equipment that has experienced
difficulty in testing to the existing DOE
test procedure. Among these changes,
DOE proposes to adopt the stack
temperature adjustment described by
Johnston when using the tested
combustion efficiency of large steam
commercial packaged boilers to
represent the combustion efficiency of
large commercial packaged boilers in
hot water mode.

Application for Waiver for the Efficiency
Rating of Commercial Space Heating
Boilers
In accordance with the provisions of the
Code of Federal Regulations Part 431,
paragraph 431.401, Johnston Boiler Company
is hereby petitioning for a waiver from the
following test procedures specified for
Commercial Packaged Boilers:
1. Paragraph 431.86 Uniform test method
for the measurement of energy efficiency of
commercial packaged boilers. This section
requires the boilers be tested using the
provisions of HI BTS–2000. We propose to
use the newly published AHRI 1500, 2015
Standard for Performance Rating of
Commercial Space Heating Boilers. There are
several issues that make BTS 2000
incompatible with the larger boilers that were
identified in previous waiver requests. AHRI
has worked diligently over the past year to
revise BTS–2000 in order to address those
issues and make BTS–2000 suitable for use
with larger boilers. AHRI Standard 1500 is
the result of that work. Use of this new
standard is required as it is compatible with
the size boilers we manufacture.
2. Paragraph 431.86(c)(1)(iv) The
requirement to use test conditions specified
in BTS–2000 specifically the requirements
for the test pressure for steam boilers, the
required water temperatures for hot water
boilers and instrumentation requirements
seem to refer back to the middle of the last
century rather than the present day, for
example:
• The 0 to 2 psig test pressure for steam
boilers may be perfectly adequate for
residential and small commercial (cast iron)
boilers sized boilers, however is not
compatible with large boilers as it will cause
water carryover in large quantities, and an
inability to meet design water flow rates and
firing rates. Typically test pressures in range
10 to 12 psig are required.
• Test temperatures defined for hot water
boilers are guaranteed to cause thermal shock
problems in large boilers.
• The instrumentation chart, Table 1, has
several problem areas, as follows:
Æ Steam pressure cannot be measured by
mercury manometer as the use of mercury in
VerDate Sep<11>2014
20:48 Jun 10, 2016
Jkt 238001
instruments and controls is banned. The
correct instrument is a Bourdon Tube Gauge
0 to 30 psig
Æ Large boilers typically fire into a positive
pressure combustion chamber, thus gas
pressure, firebox pressure and vent/flue
pressure instruments all need to reflect this.
Æ The use of scales to measure water/
condensate/moisture flow rates is
incompatible with the sheer volume of these
fluids being used or generated by large
boilers. Water flow meters should be used
and in the case of moisture content, current
practice is to use a throttling calorimeter.
Æ The measurement of carbon dioxide as a
means of calculating excess air or oxygen is
considered obsolete in the large boiler
industry. Direct measurement of excess
oxygen is the preferred method as modern
oxygen meters can easily be calibrated
against the oxygen in the ambient air.
Æ Carbon Monoxide levels are no longer
measured as a percentage. The current
preferred unit is ppm.
AHRI 1500 has taken into account these
changes.
3. Paragraph 431.86(c)(2)(iii)(B) Rating.
This paragraph specifies that for boilers
capable of supplying either steam or hot
water, that they are tested on steam only, the
hot water efficiency shall be based on the
testing in the steam mode. We propose to use
an adjusted steam efficiency for hot water
when testing on steam only. The adjustment
is made to the measured stack temperature to
be used in calculating efficiency based on the
relative difference between the flue gas
temperature and the bulk fluid temperature
when operating on steam v hot water using
the following relationship:
Tstackhw = (Tstacksteam ¥ Tsat) + Tbulkhw
Where:
Tstackhw = Stack temperature to be used to
determine the efficiency on hot water
Tstacksteam = Measured stack temperature
when testing on steam
Tsat = Saturation temperature of steam at the
test pressure
Tbulkhw = 180 °F
The dominant heat transfer variable for
both steam and hot water boilers is the gas
side coefficient and there is very little
difference in the overall heat transfer
coefficient between steam and hot water
boilers. It is possible therefore to determine
what a hot water boiler stack temperature
will be, based on a steam test and the bulk
fluid temperature difference within the
boiler. We believe that using this adjusted
stack temperature to calculate efficiency is a
more accurate representation of the actual
efficiency when operating as a hot water
boiler than simply using the steam efficiency
value.
4. We will use the vertical stack
arrangement shown on our Drawing
#327A0040 Johnston Boiler General
Arrangement D.O.E. Efficiency Test
(attachment B). The large volume of our flue
gas in relation to the flue diameter results in
relatively high velocities with resulting
turbulence. This straight stack arrangement is
shown in our operating manual and ABMA’s
‘‘Packaged Boiler Engineering Manual’’.

is an upper limit for input rating. However,
the stated purpose of the AHRI standard 1500
is for Commercial Space Heating Boilers. We
suggest that the upper input limit be
established at 12,500,000 Btu/hr.
The two major safety standards for our
industry are American Society of Mechanical
Engineers (ASME CSD–1 Controls and Safety
Devices for Automatically Fired Boilers) and
National Fire Protection Association (2015

Commercial Boilers with inputs from 400,000
to 12,500,000 Btu/hr. The scope for NFPA–
85 is for Industrial Boilers over 12,500,000
Btu/hr.

SUPPLEMENTARY INFORMATION: In a petition received July 21, 2015,
Johnston requested that the U.S. Department of Energy (``DOE'') grant a
waiver to certain models of larger commercial package boilers that
cannot be tested under the existing DOE test procedure. The models of
commercial packaged boilers at issue are models with higher input
capacities that typically require higher steam pressure and alternative
instrumentation due to the large quantities of fluids being measured.
I. Background and Authority
Title III, Part C of the Energy Policy and Conservation Act of 1975
(EPCA), as amended (42 U.S.C. 6311 et seq.), established the Energy
Conservation Program for certain industrial equipment, which includes
commercial packaged boilers.\1\ Part C specifically includes
definitions (42 U.S.C. 6311), energy conservation standards (42 U.S.C
6313), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C.
6315), and the authority to require information and reports from
manufacturers (42 U.S.C. 6316). Part C authorizes the Secretary of
Energy (the Secretary) to prescribe test procedures that are reasonably
designed to produce results that measure energy efficiency, energy use,
and estimated annual operating costs, and that are not unduly
burdensome to conduct. (42 U.S.C. 6314(a)(2)) With respect to
commercial packaged boilers, Part C requires DOE to use industry test
procedures developed or recognized by the Air-Conditioning, Heating,
and Refrigeration Institute (AHRI) or the American Society of Heating,
Refrigerating, and Air-Conditioning Engineers (ASHRAE), as referenced
in ASHRAE/IES \2\ Standard 90.1, ``Energy Standard for Buildings Except
Low-Rise Residential Buildings.'' (42 U.S.C. 6314(a)(4)(A)) Further, if
such an industry test procedure is amended, DOE is required to amend
its test procedure to be consistent with the amended industry test
procedure, unless it determines, by rule published
[[Page 38162]]
in the Federal Register and supported by clear and convincing evidence,
that the amended test procedure would be unduly burdensome to conduct
or would not produce test results that reflect the energy efficiency,
energy use, and estimated operating costs of that equipment during a
representative average use cycle. (42 U.S.C. 6314(a)(4)(B)). The test
procedure for commercial packaged boilers is contained in 10 CFR part
431, subpart E.
---------------------------------------------------------------------------
\1\ For editorial reasons, upon codification in the U.S. Code,
Part C was re-designated Part A-1.
\2\ Illuminating Engineering Society.
---------------------------------------------------------------------------
DOE's regulations for covered products and equipment permit a
person to seek a waiver from the test procedure requirements for
covered commercial equipment if at least one of the following
conditions is met: (1) The petitioner's basic model contains one or
more design characteristics that prevent testing according to the
prescribed test procedures; or (2) 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. 10 CFR 431.401(a)(1). A petitioner must include in its petition
any alternate test procedures known to the petitioner to evaluate the
basic model in a manner representative of its energy consumption. 10
CFR 431.401(b)(1)(iii).
DOE may grant a waiver subject to conditions, including adherence
to alternate test procedures. 10 CFR 431.401(f)(2). As soon as
practicable after the granting of any waiver, DOE will publish in the
Federal Register a notice of proposed rulemaking to amend its
regulations so as to eliminate any need for the continuation of such
waiver. As soon thereafter as practicable, DOE will publish in the
Federal Register a final rule. 10 CFR 431.401(l).
II. Petition for Waiver of Test Procedure
On July 21, 2015, Johnston submitted a petition for waiver from the
DOE test procedure for certain basic models of its commercial packaged
boilers. The DOE test procedure for commercial packaged boilers is set
forth at 10 CFR 431.86 and incorporates by reference Hydronics
Institute (HI) BTS-2000, ``Method to Determine Efficiency of Commercial
Space Heating Boilers'' (BTS-2000).
According to Johnston, there are several issues that make BTS-2000
incompatible with larger commercial packaged boilers, including those
identified in its petition for waiver. Johnston stated that the
requirements to use test conditions specified in BTS-2000 and the
instrumentation requirements are outdated. Specifically, Johnston
indicated the following regarding the test conditions:
The 0 to 2 psig test pressure for steam boilers may be
adequate for residential and small commercial (cast iron) boilers sized
[commercial packaged] boilers, however such steam pressures are not
compatible with large [commercial packaged] boilers as it will cause
water carryover in large quantities, and an inability to meet design
water flow rates and firing rates;
Typically test steam pressures in the range of 10 to 12
psig are required; and
Test temperatures defined for hot water [commercial
packaged] boilers cause thermal shock problems in large [commercial
packaged] boilers.
Johnston also indicated the following regarding the instrumentation
chart in Table 1 of section 6.0, ``Instruments,'' of BTS-2000:
Steam pressure cannot be measured by mercury manometer as
the use of mercury in instruments and controls is banned; the correct
instrument is a Bourdon Tube Gauge for pressures of 0 to 30 psig;
Large boilers typically fire into a positive pressure
combustion chamber, thus gas pressure, firebox pressure and vent/flue
pressure instruments all need to reflect this;
The use of scales to measure water/condensate/moisture
flow rates is incompatible with the volume of these fluids being used
or generated by large [commercial packaged] boilers; water flow meters
should be used and in the case of moisture content, current practice is
to use a throttling calorimeter;
The measurement of carbon dioxide as a means of
calculating excess air or oxygen is considered obsolete in the large
[commercial packaged] boiler industry; direct measurement of excess
oxygen is the preferred method as modern oxygen meters can easily be
calibrated against the oxygen in the ambient air;
Carbon Monoxide levels are no longer measured as a
percentage; the current preferred unit is parts per million (ppm).
To address these concerns, Johnston proposes to use the newly
published American National Standards Institute (ANSI)/Air-
Conditioning, Heating, and Refrigeration Institute (AHRI) 1500-2015,
``Standard for Performance Rating of Commercial Space Heating Boilers''
(ANSI/AHRI Standard 1500-2015) in place of BTS-2000. AHRI developed
ANSI/AHRI Standard 1500-2015 as a replacement for BTS-2000 in order to
make the test procedure suitable for use with larger commercial
packaged boilers, as well as improve and clarify the test method.
Johnston claims that use of this ANSI/AHRI Standard 1500-2015 is
necessary as it is compatible with the size of commercial packaged
boilers they manufacture.
Additionally, for the large commercial packaged boilers capable of
supplying either steam or hot water identified in this petition,
Johnston requests that, when determining the combustion efficiency in
hot water mode based on testing in steam mode only, the combustion
efficiency rating be determined based on an adjusted combustion
efficiency. Johnston requests that an adjustment be made to the
measured stack temperature to be used in calculating combustion
efficiency based on the relative difference between the flue gas
temperature and the bulk fluid temperature when operating in steam mode
as opposed to hot water using the following relationship:
Tstack, hw = (Tstack, steam - Tsat) +
Tbulk, hw
where Tstack, hw is the stack temperature to be used to
determine the combustion efficiency in hot water mode,
Tstack, steam is the measured stack temperature when testing
on steam, Tsat is the saturation temperature of steam at the
test pressure, and Tbulk, hw is the temperature of the
outlet water when testing in hot water mode and is equal to 180 [deg]F.
According to Johnston, using this adjusted stack temperature to
calculate combustion efficiency is a more accurate representation of
the actual efficiency when operating as a hot water commercial packaged
boiler than simply using combustion efficiency value for steam mode.
Johnston also requests to use the vertical stack arrangement shown
on their ``Drawing #327A0040 Johnston Boiler General Arrangement D.O.E.
Efficiency Test (attachment B).'' DOE's existing test procedure
incorporates section 7.0 ``Apparatus'' of BTS-2000 with respect to test
setup including flue connection requirements. (DOE notes that the term
``flue,'' not ``stack,'' is used throughout its test procedure
regulations as well as BTS-2000). The flue requirements differ
depending on the characteristics of the commercial packaged boiler,
including:
Whether the unit is oil-fired or gas-fired, and if gas-
fired;
Whether the unit is direct vent;
Whether the unit has an input rating of more than 400,000
Btu/h;
Whether the unit is discharges vent gases horizontally or
vertically; and
Whether the unit is condensing.
According to Johnston, the large volume of flue gas in relation to
the flue
[[Page 38163]]
diameter results in relatively high velocities and therefore creates
turbulence. Johnston indicates that this straight stack arrangement is
shown in their operating manual and in the American Boiler Manufacturer
Association's (ABMA) ``Packaged Boiler Engineering Manual.'' DOE
requests comment on how turbulence affects measured efficiency under
the current test procedure, and how use of the vertical stack
arrangement shown in the drawing provided by Johnston would prevent
turbulence.
In addition, Johnston stated that ANSI/AHRI Standard 1500-2015 does
not clarify whether there is an upper limit for fuel input rate to
which the standard applies. However, the scope of ANSI/AHRI Standard
1500-2015 is identified as ``commercial space heating boilers'' in
section 1.1. (Note: The term ``commercial space heating boiler'' is not
defined in ANSI/AHRI Standard 1500-2015.) Johnston suggested that the
upper fuel input rate limit be established at 12,500,000 Btu/hr.
Johnston stated that the two major safety standards for the industry
are American Society of Mechanical Engineers (ASME) CSD-1 Controls and
Safety Devices for Automatically Fired Boilers (ASME CSD-1) and
National Fire Protection Association (NFPA)-85-2015 Boiler and
Combustion Systems Hazard Code (NFPA-85). Johnston further indicated
that the scope of ASME CSD-1 is for commercial boilers with inputs from
400,000 to 12,500,000 Btu/hr and the scope for NFPA-85 is for
industrial boilers over 12,500,000 Btu/hr. DOE notes that neither the
existing DOE test procedure or energy standards establish an upper
limit in terms of fuel input rate for which they apply. Consequently,
DOE is declining to consider Johnston's request for an upper limit for
the fuel input rate which would limit the scope of applicability of the
test procedure in this proceeding.
DOE notes that it has published a notice of proposed rulemaking
(NOPR) to amend its test procedure for commercial packaged boilers
prescribed in 10 CFR part 431 subpart E (March 2016 CPB TP NOPR). 81 FR
14641 (Mar. 17, 2016). The proposed amended test procedure addresses,
among other changes, most of the issues raised in this waiver request
by incorporating by reference ANSI/AHRI Standard 1500-2015 as a
replacement for BTS-2000 in the DOE test procedure for commercial
packaged boilers. In addition to adopting ANSI/AHRI Standard 1500-2015
as a replacement for BTS-2000, DOE further proposes several
modifications to its test procedure that are not captured in ANSI/AHRI
Standard 1500-2015 in order to improve repeatability, add
clarification, and accommodate testing of some equipment that has
experienced difficulty in testing to the existing DOE test procedure.
Among these changes, DOE proposes to adopt the stack temperature
adjustment described by Johnston when using the tested combustion
efficiency of large steam commercial packaged boilers to represent the
combustion efficiency of large commercial packaged boilers in hot water
mode.

Application for Waiver for the Efficiency Rating of Commercial Space
Heating Boilers
In accordance with the provisions of the Code of Federal
Regulations Part 431, paragraph 431.401, Johnston Boiler Company is
hereby petitioning for a waiver from the following test procedures
specified for Commercial Packaged Boilers:
1. Paragraph 431.86 Uniform test method for the measurement of
energy efficiency of commercial packaged boilers. This section
requires the boilers be tested using the provisions of HI BTS-2000.
We propose to use the newly published AHRI 1500, 2015 Standard for
Performance Rating of Commercial Space Heating Boilers. There are
several issues that make BTS 2000 incompatible with the larger
boilers that were identified in previous waiver requests. AHRI has
worked diligently over the past year to revise BTS-2000 in order to
address those issues and make BTS-2000 suitable for use with larger
boilers. AHRI Standard 1500 is the result of that work. Use of this
new standard is required as it is compatible with the size boilers
we manufacture.
2. Paragraph 431.86(c)(1)(iv) The requirement to use test
conditions specified in BTS-2000 specifically the requirements for
the test pressure for steam boilers, the required water temperatures
for hot water boilers and instrumentation requirements seem to refer
back to the middle of the last century rather than the present day,
for example:
The 0 to 2 psig test pressure for steam boilers may be
perfectly adequate for residential and small commercial (cast iron)
boilers sized boilers, however is not compatible with large boilers
as it will cause water carryover in large quantities, and an
inability to meet design water flow rates and firing rates.
Typically test pressures in range 10 to 12 psig are required.
Test temperatures defined for hot water boilers are
guaranteed to cause thermal shock problems in large boilers.
The instrumentation chart, Table 1, has several problem
areas, as follows:
[cir] Steam pressure cannot be measured by mercury manometer as
the use of mercury in instruments and controls is banned. The
correct instrument is a Bourdon Tube Gauge 0 to 30 psig
[cir] Large boilers typically fire into a positive pressure
combustion chamber, thus gas pressure, firebox pressure and vent/
flue pressure instruments all need to reflect this.
[cir] The use of scales to measure water/condensate/moisture
flow rates is incompatible with the sheer volume of these fluids
being used or generated by large boilers. Water flow meters should
be used and in the case of moisture content, current practice is to
use a throttling calorimeter.
[cir] The measurement of carbon dioxide as a means of
calculating excess air or oxygen is considered obsolete in the large
boiler industry. Direct measurement of excess oxygen is the
preferred method as modern oxygen meters can easily be calibrated
against the oxygen in the ambient air.
[cir] Carbon Monoxide levels are no longer measured as a
percentage. The current preferred unit is ppm.
AHRI 1500 has taken into account these changes.
3. Paragraph 431.86(c)(2)(iii)(B) Rating. This paragraph
specifies that for boilers capable of supplying either steam or hot
water, that they are tested on steam only, the hot water efficiency
shall be based on the testing in the steam mode. We propose to use
an adjusted steam efficiency for hot water when testing on steam
only. The adjustment is made to the measured stack temperature to be
used in calculating efficiency based on the relative difference
between the flue gas temperature and the bulk fluid temperature when
operating on steam v hot water using the following relationship:
Tstackhw = (Tstacksteam - Tsat) +
Tbulkhw
Where:
Tstackhw = Stack temperature to be used to determine the
efficiency on hot water
Tstacksteam = Measured stack temperature when testing on
steam
Tsat = Saturation temperature of steam at the test
pressure
Tbulkhw = 180 [deg]F
The dominant heat transfer variable for both steam and hot water
boilers is the gas side coefficient and there is very little
difference in the overall heat transfer coefficient between steam
and hot water boilers. It is possible therefore to determine what a
hot water boiler stack temperature will be, based on a steam test
and the bulk fluid temperature difference within the boiler. We
believe that using this adjusted stack temperature to calculate
efficiency is a more accurate representation of the actual
efficiency when operating as a hot water boiler than simply using
the steam efficiency value.
4. We will use the vertical stack arrangement shown on our
Drawing #327A0040 Johnston Boiler General Arrangement D.O.E.
Efficiency Test (attachment B). The large volume of our flue gas in
relation to the flue diameter results in relatively high velocities
with resulting turbulence. This straight stack arrangement is shown
in our operating manual and ABMA's ``Packaged Boiler Engineering
Manual''.
5. AHRI Standard 1500, Page 1, Section 2, Paragraph 1.1 and 2.2.
It is not clear if there is an upper limit for input rating.
However, the stated purpose of the AHRI standard 1500 is for
Commercial Space Heating Boilers. We suggest that the upper input
limit be established at 12,500,000 Btu/hr.
The two major safety standards for our industry are American
Society of Mechanical Engineers (ASME CSD-1 Controls and Safety
Devices for Automatically Fired Boilers) and National Fire
Protection Association (2015 NFPA-85 Boiler and Combustion Systems
Hazard Code). The scope of CSD-1 is for Commercial Boilers with
inputs from 400,000 to 12,500,000 Btu/hr. The scope for NFPA-85 is
for Industrial Boilers over 12,500,000 Btu/hr.
The basic models that this request is applicable to are as
follows:

These manufacturers will be notified by Johnston Boiler Company of
this waiver, if and when the deviation is granted, in accordance
with paragraph 431.401(c).
