Preface

This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of gas-fired unvented room heaters. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on appliances designed for the utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this Standard are intended to help reduce such risks while retaining the normal function of the appliance.

Nothing in this standard is to be considered in any way as indicating a measure of quality beyond compliance with the provisions it contains. It is designed to allow compliance of unvented room heaters, the safety, construction and performance of which may exceed the various provisions specified herein. In its preparation, recognition has been given to possibilities of improvement through ingenuity of design. As technical advances take place, revisions may become necessary. When they are believed desirable, recommendations or suggestions should be forwarded to the Chairman of Z21/83 Committee, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131. A proposal form is provided in the back of this document.

Safe and satisfactory operation of a gas-fired unvented room heater depends to a great extent upon its proper installation, use and maintenance. It should be installed in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54; manufacturers’ installation instructions and local municipal codes.

Users of this American National Standard are advised that the devices, products and activities within its scope may be subject to regulation at the Federal, state or local level. Users are strongly urged to investigate this possibility through appropriate channels. In the event of a conflict with this standard, the Federal, state or local regulations should be followed.

This standard is intended to be used by the manufacturing sector and by those applying the equipment by those responsible for its proper installation. It is the responsibility of these users to determine that in each case this standard is suitable for and applicable to the specific use they intend.
