PREFACE This publication represents a basic standard for safe operation, substantial and durable constru

22、ction, and acceptable performance of gas-fired toilets. It is the result of years of experience in the manufacture, testing, installation and mainte- nance of and research on toilets designed for the utilization of gas. Nothing in this standard is to be considered in any way as indicating a measure

23、of quality beyond compliance with the provisions it contains. It is designed to allow compliance of gas-fired toilets, the construction and performance of which may exceed the various provisions specified herein. In its preparation, full recognition has been given to possibilities of improvement thr

24、ough ingenuity of design. As progress takes place, revisions may become necessary. When they are believed desirable, recommendations should be forwarded to the Chairman of the American National Standards Committee 221, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131. Safe and satisfactory oper

25、ation of a gas-fired toilet depends to a great extent upon its proper installation, and it should be installed, as applicable, in accordance with the National Fuel Gas Code, ANSI 2223.1-1980; the Manufactured Home Con- struction and Safety Standard, Title 24 CFR, Part 32-80 formerly the Federal Stan

26、- dard for Mobile Home Construction and Safety, Title 24 (Part 280) ,19751; the Stan- dard for Recreational Vehicles, (Travel Trailers, Motor Homes, Truck Campers, Camping Trailers) ANSIlNFPA 5OlC-1977; manufacturers installation instruc- tions; and local municipal codes. CAUTION NOTICE: This Americ

27、an National Standard may be revised or with- drawn at any time. The procedures of the American National Standards Institute, Inc., require that action be taken to reaffirm, revise or withdraw this standard no later than five (5) years from the date of approval. Purchasers of American National Standa

28、rds may receive current information on all standards by calling or writing the American National Standards Institute, Inc., 1430 Broadway, New York, New York 10018, (212) 354-3300. HISTORY OF THE DEVELOPMENT OF STANDARD FOR GAS-FIRED TOILETS (This History is informative and is not part of the standa

29、rd.) American National Standards Committee 221, at its April 5, 1972 meeting, agreed that a standard for gas-fired toilets utilizing an incineration process should be developed and assigned the task to its Subcommittee on Standards for Domestic Gas-Fired Incinerators. Prior to this time, the constru

30、ction and performance of gas-fired toilets had been evaluated under the applicable provisions of the domestic gas-fired incinerator standard (221.6) and guidelines formulated by the 221 incinerator subcommit- tee. A draft of the standard for gas-fired toilets, patterned after the domestic incinerato

31、r standard, was reviewed and modified by the incinerator subcommittee at its June 12-13, 1973 meeting, by a working group of the subcommittee at its February 18-19,1974 meeting, and again by the subcom- mittee at its November 6-7, 1974 meeting. The resultant fourth draft standard, which covered both

32、 natural draft and forced draft appliances for indoor installation, includ- ing in mobile homes and recreational vehicles, was dis- tributed for review and comment during January 1975. The incinerator subcommittee, at its October 21,1975 meeting, following reconsideration of the draft standard in th

33、e light of comments received, recommended the draft standard to the 221 Committee. The 221 Committee subse- quently adopted the proposed stndard at its April 14,1976 meeting. The first edition of the gas-fired toilet standard was approved as American National Standard by the American National Standa

34、rds Institute, Inc., on January 5, 1977. Following the procedure outlined above, further revi- sions to this standard were developed in line with industry developments. This, the second edition of the gas-fired toilet standard, was approved as American National Stan- dard by the American National St

35、andards Institute, Inc., on February 15,1983. AMERICAN NATIONAL STANDARDS COMMITTEE 221 HOWARD I. FORMAN, Chairman W. L. WALLS, Vice Chairman F. G.
