25、r and consumer interests,establish and improve the some 8500 national consensusstandards currently approved as American NationalStandards.ANSI provides that the interests of the public mayhave appropriate participation and representation instandardization activity, and cooperates withdepartments and

26、 agencies of U.S. Federal, state andlocal governments in achieving compatibility betweengovernment codes and standards and the voluntarystandards of industry and commerce.ANSI represents the interests of the United Statesin international nontreaty organizations such as theInternational Organization

27、for Standardization (ISO) andthe International Electrotechnical Commission (IEC).The Institute maintains close ties with regionalorganizations such as the Pacific Area StandardsCongress (PASC) and the Pan American StandardsCommission (COPANT). As such, ANSI coordinates theactivities involved in the

It is the result of years ofexperience in the manufacture, testing, installation, maintenanc

31、e, inspection and research on vented gasfireplace heaters designed for utilization of gas. There are risks of injury to persons inherent inappliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in thisstandard are intended to help reduce such risks while

32、 retaining the normal operation of the appliance.Nothing in this standard is to be considered in any way as indicating a measure ofquality beyond compliance with the provisions it contains. It is designed to allow compliance of ventedgas fireplace heaters, the safety construction and performance of

33、which may exceed the variousprovisions specified herein. In its preparation, recognition has been given to possibilities of improvementthrough ingenuity of design. As progress takes place, revisions may become necessary. When they arebelieved desirable, recommendations or suggestions should be forwa

35、place heaters depends to a greatextent upon its proper installation, use and maintenance. It should be installed, as applicable, inaccordance with the National Fuel Gas Code, ANSI Z223.1; the Natural Gas Installation Code, CAN/CGA-B149.1; the Propane Installation Code, CAN/CGA-B149.2.Users of this A

In Canada the Standards Committee and the Interpro

41、vincial GasAdvisory Council normally stipulate an effective date for the standard.HISTORY OF THE DEVELOPMENT OF THE STANDARDFOR DOMESTIC GAS CONVERSION BURNERS(This History is informative and is not part of the standard.)With the onset of the Free Trade Agreementbetween the United States and Canada

42、onJanuary 2, 1988, significant attention was givento the harmonization of the United States andCanadian safety standards addressing gas-firedequipment for residential, commercial andindustrial applications. It was believed that theelimination of the differences between thestandards would remove pote

43、ntial trade barriersand provide an atmosphere in which NorthAmerican manufacturers could market morefreely in the United States and Canada. Theharmonization of these standards was also seenas a step toward harmonization withinternational standards. Joint subcommitteeswere established to facilitate t

44、he standardsharmonization process between the United Statesand Canada.At its August 22, 1995 meeting, the Z21Subcommittee on Standards for Domestic GasConversion Burners reviewed a draft by-nationalstandard for gas conversion burners which wassubsequently distributed for review andcomment December 1

45、995.The first draft harmonized standard wasbased on current coverage form the AmericanNational Standard for Domestic Gas ConversionBurners, ANSI Z21.17-1991, Addenda ANSIZ21.17a-1993 and Addenda ANSI Z21.17b-1994,plus the National Standard of Canada forDomestic Gas Conversion Burners,CAN/CGA 2.7-M86

46、.Following reconsideration and modification ofthe proposed draft standard, in light ofcomments received, the domestic gas conversionburner subcommittee by letter ballot datedNovember 15, 1997 recommended the proposeddraft standard to Accredited StandardsCommittee Z21/83 and the (Interim CSA)Standard

47、s Steering Committee for approval.The proposed draft of the harmonizedstandard for gas conversion burners, as modifiedby the subcommittee, was approved by theZ21/83 Committee by letter ballot datedFebruary 26, 1998, and by the (Interim CSA)Standards Steering Committee by letter ballotdated August 6,
