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.
    The following basic models are included in Johnston's petition:

III. Summary and Request for Comments

    Through this notice, DOE is publishing Johnston's petition for 
waiver pursuant to 10 CFR 431.401(b)(1)(iv). The petition contains no 
confidential information. The petition includes a suggested alternate 
test procedure applicable to measurement of energy efficiency of 
certain models of commercial packaged boilers manufactured by Johnston.
    DOE solicits comments from interested parties on all aspects of the

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:
