DEPARTMENT OF ENERGY Office of Conservation and Renewable Energy Energy Conservation Program for Consumer Products ; Petition for Waiver of Furnaces Test Procedures From Lennox Industries, Inc.
No. F-OWI - AGENCY : Office of Conservation and Renewable Energy, DOE 

### ACTIWt Petition for waiver of test procedures. Consumer Products (other than - automobiles ) was established pursuant to the Energy Policy and Conservation Act (SPCA ), Pub. L, 94-10& 89 Stat 917, as amended by the National Energy Conservation Policy Act (NECPA), Pub. L 95-819, 92 Stat

. 3288, 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. DOE has amended the prescribed test procedures by adding 1o CFR 430.27, Petitions for Waiver , to allow the Assistant Secretary for Conservation and Renewable Energy temporarily to waive test procedures for a particular basic model

. 45 FR 84108 ( September 20, 1980). Waivers may be granted when one or more design characteristics of a basic model either prevent testing of the basic model according to the prescribed test procedures or lead to results so unrepresentative of the model's true

DOE solicits comments, data, and information respecting the petition, particularly the request to.permit in-house testing. 22, issued in Washington, D.C., February 1982.' Joseph 1. Tribble, Assistant cue ary, Conservation and Renewable Energy. October 9, 1981. 1. Petition for Waiver Gentlemen: In accordance with 10 CFR 430.27, this is a petition for waiver from the test procedure specified in 10 CFR Part 430, Subpart B, Appendix N, as amended August 12, 1980. Lennox Industries Inc. has developed and is planning to market a line of pulse combustion, condensing, gas-fired, warm air furnaces that fall within the scope. of 10 CFR Part 430, Subpart B. Appendix N. Inasmuch as a furnaces manufacturer may not make any energy efficiency representations on furnaces unless they are based on the results of the Appendix N tests, and the Appendix N tests do not give full ' credit for the efficiency increase due to latent beat recovery, we submit this petition. 2. General Description of Petitioner's Business Lennox industries Inc., a U.S. corporation. has been a major manufacturer of both residential and commercial heating applicances for more than 85 years and hasnow developed a line of high efficiency, gasfired warm air furnaces which operate on the principle of pulse combustion that will condense a portion of the water vapor in the flue products. These furnaces will be manufactured in five input sizes, from 40.000 British thermal units per hour (Btuh) to 130,000 Btuh, and will be marketed in the U.S. beginning in November 1981, under the model designation "G14" and the Lennox brand

name. A Lennox Model G14 Pulse Combustion Furnace Principles of Operations The model G14 furnace uses a pulse combustion burner coupled with a heat exchanger that allows the flue gas to be cooled below its dew point. thus recovering a portion of the latent beat of the water vapor in the flue products. This enables the furnace to operate at steady state efficiency levels in excess of 90% as determined by the existing Appendix N tests performed at the Lennox laboratory. The principles of operation of the Lennox' C14 pulse combustion furnace are very . similar to the Hydrothenn. Inc. Hydro-Pulse Tr boiler, which was granted a similar waiver of test procedure by the DOE on July 2, 1901. 4. DOE Test Dos Net Adequately Measure
