No. F-035).

Background

The Energy Conservation Program for

Consumer Products (other than

automobiles) was established pursuant

to the Energy Policy and Conservation

Act (SPCA), Public Law 94-163.89 stat.

917, as amended by the National Energt

Conservation Policy Act (NECPA),

Public Law 95--619, 92 stat. 3266, the

National Appliance Energy

Conservation Act of 1987 (NAECA),

Public Law 100-12, and the National

Appliance Energy Conservation

Amendments of 1988 (NAECA 1988),

Public Law 100-357, which requires DO'-:

10168 Federal Register / Vol. 57, No. 57 / Tuesday, March 24, 1992 / Notices

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.

DOE 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 Conservation

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 provided 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 immee^diate

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.

Trane filed a "Petition for Waiver,"

dated October 11, 1991, in accordance

with section 430.27 of 10 CFR part 430,

DOE published in the Federal Register

on December 11, 1991, Trane's petition

and solicited comments, data and

information respecting the petition. 56

FR 64609. Trane also filed an

"Application for Interim Waiver" under

section 430.27(g) which DOE granted on

December 5, 1991.56 FR 64609,

December 11, 1991.

No comments were received

concerning either the "Petition for

Waiver" or the "Interim Waiver." DOE

consulted with the Federal Trade

Commission (FTC) concerning the Trane

Petition. The FTC did not have any

objections to the issuance of the Waiver

to Trane.

Assertion and Determinations

Trane'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. Trane

requests the allowance to test using a

30-second blower time delay when

testing its YC(D,H) 036-060 rooftop

furnaces. Trane states that since the 30-

second delay is indicative of how these

models actually operate and since such

a delay results in an improvement in

efficiency of approximately 0.7 percent,

the petition should be granted.

Under specific circumstances, the

DOE test procedure contain exceptions

which allow testing with blower delay

times of less than the prescribed 1.5-

minute delay. Trane indicates that it is

unable to take advantage of any of these

exceptions for its YC(D,H) 036-060

rooftop furnaces.

Since the blower controls

incorporated on the Trane furnaces are

designed to impose a 30-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 30-second blower

time delay when testing the Trane

YC(D,H) 036-060 rooftop furnaces.

Accordingly, with regard to testing the

YC(D,H) 036-060 rooftop furnaces,

today's Decision and Order exempts

Trane from the existing provisions

regarding blower controls and allows

testing with the 30-second delay.

It is, therefore, ordered that. (1) The

"Petition for Waiver" filed by Trane

Company (Case No. F-035), 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, Trane Company, shall be

permitted to test its YC(D,H) 036-060

rooftop 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 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 103-82.

After equilibrium conditions are

achieved following the cool-down test

and the required measurements

performed, turn on the furnaces and

measure the flue gas temperature, using

the thermocouple grid described above,

at 0.5 and 2.5 minutes after the main

burner(s) cones 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, Trane

Company 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 YC(D,H)

036-060 rooftop furnaces manufactured

by Trane Company.

(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 24, 1992. This

Waiver supersedes the Interim Waiver

granted Trane Company on December 5,

1991. 56 FR 64609, December 11, 1991
