Decision and Order _

In the Matter of. Carrier Corporation. (Case

No. F-065)

Background

The Energy Conservation Program for

Consumer Products (other. than

automobiles) was established pursuant

to the Energy Policy and Conservation

Act (EPCA), Public Law 94-163, 89 Stat.

917, as amended by the National Energy

Conservation Policy Act (NECPA),

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

National Appliance•Energy

Conservation Act of 1987 (NAECA),

Public Law 100-12, the National

Appliance Energy Conservation

Amendments of 1988 (NAECA 1988),

Public Law 100-357, and the Energy

Policy Act of 1992 (EPAct), Public Law

102-486, 106 Stat. 2776, 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 10 CFR part

430, subpart B.

The Department 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

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. 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

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.

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

immediate 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.

Carrier filed a "Petition for Waiver,"

dated October 13, 1993, in accordance

with § 430.27 of 10 CFR part 430. The

Department published in the Federal

Register on December 27,1993; Carrier's

petition and solicited comments, data

and information respecting the petition.

58 FR 68400: Carrier also filed an

"Application for Interim Waiver" under

section 430.27(g) which DOE granted on

December 17, 1993. 58 FR 68400,

December 27, 1993.

No comments were received

concerning either the "Petition for

Waiver" or the "Interim Waiver." The

Department consulted with The Federal

Trade Commission (FTC) concerning the

Carrier Petition. The FTC did not have

any objections to the issuance of the

waiver to Carrier.

Assertions and Determinations

Carrier'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. Carrier

requests the allowance to test using a

45-second blower time delay when

testing its 48HJ, 48HM, 48TJ/580D,

48SS/588A, and 48SX/589A induced

draft roof-top furnaces. Carrier states

that since the 45-second delay is

indicative of how these models actually

operate and since such a delay results

in an improvement in efficiency of .

approximately 0.6 percent, the petition

should be granted.

Under specific circumstances, the,

DOE test procedure contains exceptions

which allow testing with blower delay

times of less than the prescribed 1.5

minute delay. Carrier indicates that it is

unable to take advantage of any of these

exceptions for its 48HJ, 48HM, 48TJ/

580D, 48SS/588A., and 48SX1589A

induced draft roof-top furnaces.

Since the blower controls

incorporated on the Carrier 48HJ, 48HM,

48TJ/580D, 48SS/588A, and 48SX/589A.

induced draft roof-top furnaces are

designed to impose a 45-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

g;anted to allow the 45-second blower

time delay when-testing the Carrier

48HJ, 48HM, 48TJ/580D, 48SS1588A,

and 48SX/589A induced draft roof-top

furnaces. Accordingly, with regard to

testing the above induced draft roof-top

furnaces, today's Decision and Order

exempts Carrier from the existing

provisions regarding blower controls

and allows testing with the 45-second

delay.

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

"Petition for Waiver" filed by Carrier

Corporation. (Case No. F-065) 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, Carrier Corporation,

shall be permitted to test its 48HJ,

48HM, 48TJ/580D, 48SS/588A, and '

48SX/589A induced draft roof-top

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 Standard

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

Standard 103-82. 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 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

CAS-RM-79-104 COMMENT 103
14396 Federal Register / Vol. 59, No. 59 / Monday, March 28, 1994 / Notices

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 10.01 inch of water column

of the manufacturer's recommended onperiod draft.

(iii) With the exception of the

modifications set forth above, Carrier

Corporation 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 48HJ,

48HM. 48TJ/580D, 48SS/588A, and

48SX1589A induced draft'roof-top

furnaces manufactured by Carrier

Corporation.

(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 21, 1994, this

Waiver supersedes the Interim Waiver

granted the Carrier Corporation on

December 17, 1993. 58 FR 68400,

December 27, 1993 (Case No. F-065).

Issued In Washington , DC, March 21. 1994.
