-904 Federal Register / Vol. 57, No. a / Thursday, January 9. 1992 / Notices Energy Conservation Program for Consumer Products; Granting of the Application for Interim Waiver and Publishing of the Petition for Waiver of Furnace Test Procedures From The Trane Company ( Case No. F-040) AGENCY : Office of Conservation and Renewable Energy, Department of Energy. BUMMlARY : Today 's notice publishes a letter granting an Interim Waiver to The Trane Company (Trane) from the existing Department of Energy (DOE) test procedures for furnaces regarding blower time delay for the company's TUD-C. TUD-R. TDD-C and TDD-R central furnaces. 

### Today 's notice also publishes a "Petition for Waiver" from Trane. Trane's Petition for Waiver requests DOE test procedures relating to the blower time delay specification. Trane seeks to test using a blower delay time of 45 seconds for its TUD-C, TDD-R, TDD-C and TDD- R central furnaces instead of the specified 1.5-minute delaybetween burner on-time and blower ontime. DOE is soliciting comments, data, and information respecting the Petition for Waiver. DATE : DOE will accept comments, data, and information not later than February 10,1992. ADDRESSES: Written comments and statements shall be sent to: Department of Energy , Office of Conservation and Renewable Energy, Case No. F-040, Mail Stop CE- 90, room 6B-025 , Forrestal Building, 1000 Independence Avenue, SW., Washington.

. Trane is requesting the use of - i5 seconds instead of 1.5 minutes when testing our TUD-C, TDD-R. TDD-C and TDD-R central furnace families incorporating a timed fan control with a fixed timed on - adjustment of 45 seconds . The current procedure does not credit Trane for additional energy savings that are realized when a shorter blower on time is utilized. Test data for each model series indicates an average 1% AFUE increase when a 45 second timed on delay is used
. Copies of confidential test data confirming these energy savings will be forwarded to you upon request. Trane is confident that this petition for Waiver will be granted , and therefore,' requests an interim Waiver until the final ruling is made

. Similar waivers have been granted to Evcon , Rheem Manufacturing, Carrier, Inter-City Products, and Lennox Industries

. Also, the proposed ASHRAE 103- 8e currently under consideration by DOE contains the coverage requested in this Petition for Waiver. Manufacturers that domestically market similar products have been sent a copy of this Petition for Waiver and Application for Interim Waiver. •- • Sincerely, James T. VerShaw, Manager. F
