SUPPLEMENTARY INFORMATION: In accordance with 10 CFR 430.27(g). notice is hereby given of the issuance of the
Decision and Order as set out below. In the Decision and Order, Goodman has been granted a waiver for its PG and PGX series rooftop furnaces, permitting the company to use an alternate test method in determining the Annual Fuel Utilization Efficiency (AFUE).

### Decision and Order

In the matter of GoodmanManufacturing Corporation (Case No. F030)

Background

The Energy Conservation Program for Consumer Products (other than automobiles) 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). 

### 61713

Public Law 100-12, and the National Appliance Energy Conservation Amendments of 1988 (NAECA 1988). Public Law 100-357, requires DOE to prescribe standardized test procedures to meaure 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 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 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 determinaton on the Petition for Waiver, whichever is sooner, and may be extended for an additional 180 days

, if necessary.
Goodman filed a "Petition for Wavier" dated January 16

, 1991

, in accordance with 1430.27 of 10 CFR part 430. DOE published in the Federal Register on May 3,1991

, Goodman's petition and solicited comments, data and

information respecting the petition. 56
FR 20421. Goodman also filed an "Application for Interim Waiver" under § 430.27(g) which DOE granted on April 26, 1991. 56. 20421, May 3, 1991. 

### No comments were received concerning either the "Petition for Waiver" or the "Interim Waiver." DOE consulted with Federal Trade Commission (FTC), concerning the Goodman Petition. The FTC did not have any objections to the issuance of the Waiver to Goodman.

Assertions and Determinations

Goodman'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. Goodman requests the allowance to test using a 30-second blower time delay when testing its PG and PGX series rooftop furnaces. Goodman 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 1.0 percent, the Waiver should be granted. Under specific circumstances, the DOE test procedures contain exceptions which allow testing with blower delay times of less than the prescribed 1.5- minute delay. Goodman indicates that it is unable to take advantage of any of these exceptions for its PG and PGX series rooftop furnaces.
Since the blower controls incorporated on the Goodman 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 Goodman PG, PSX series rooftop furnaces. Accordingly, with regard to testing the PG and PGX series rooftop furnaces, today's Decision and Order exempts Goodman 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 the Goodman Manufacturing Corporation (Case No. F-030) is hereby granted as set forth in paragraph (2) below, subject to the provisions of paragraphs (3), (4), and (5). (2) Not withstanding any contrary provisions of appendix N of 10 CFR part 430, subpart B. the Goodman Manufacturing Corporation shall be permitted to test its PG and PGX series 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 measurement 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) 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 activities 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 stop
watch. 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 modification set forth above, Goodman Manufacturing 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 PG and PGX series rooftop furnaces manufactured by Goodman Manufacturing 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 October 15, 1991, this Waiver supersedes the Interim Waiver Granted Goodman Manufacturing Corporation on April 26,1991. 56 FR 20421, May 3,1991, (Case No. F-030).

Issued in Washington. DC, October 3.1991.
