    Manually Operated Piezo-Electric Spark Gas Ignition Systems and Components

    SKU: 2417578 Published by CSA Group Publication Year 2005 46 pages

    Product Details

    • Preface/Scope

    Preface


    This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of manually operated piezo-electric spark gas ignition systems and components for gas appliances. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on manually operated piezo-electric spark gas ignition systems and components for gas appliances designed for 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 operation 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 manually operated piezo-electric spark gas ignition systems and components for gas appliances, the safety construction and performance of which may exceed the various provisions specified herein. In its preparation, full recognition has been given to possibilities of improvement through ingenuity of design. As progress takes place, revisions may become necessary. When they are believed desirable, recommendations or suggestions should be forwarded to the Chairman of Accredited Standards Committee Z21/83, 8501 East Pleasant Valley Road, Cleveland, Ohio 44131, or the Chairman of the CSA Technical Committee on Gas Appliances and Related Accessories, 5060 Spectrum Way, Mississauga, Ontario, Canada, L4W 5N6.


    Safe and satisfactory operation of a pilot gas filter for gas appliances depends to a great extent upon its proper installation, use and maintenance. It should be installed, as applicable, in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54; the Natural Gas and Propane Installation Code, CSA-B149.1.


    Users of this American National Standard/Canadian Standards Association Standard are advised that the devices, products and activities within its scope may be subject to regulation at the Federal, Territorial, Provincial, 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, Territorial, Provincial, state or local regulation should be followed.


    Scope


    1.1.1

    This standard applies to newly produced manually-operated piezo-electric spark gas ignition systems (see Part IV, Definitions), hereinafter referred to as piezo ignition systems, and components constructed entirely of new, unused parts and materials, which are intended to form an integral part of a gas appliance. A piezo ignition system shall perform the following

    functions:


    a. Generate piezo-electric energy (spark generator);


    b. Transmit the energy (high voltage leads); and


    c. Utilize the energy to produce arcs (spark electrode).


    Components submitted for examination under this standard shall perform one or more of the above functions; however, a component performing only b is not covered under the scope of this standard.


    1.1.2

    This standard applies to piezo ignition systems and components for use with one or more of the following gases:


    a. Natural;


    b. Manufactured;


    c. Mixed;


    d. Liquefied Petroleum; and


    e. LP gas-air mixtures.


    1.1.3

    Compliance of a piezo ignition system or component with this standard does not imply that either is acceptable for use on gas appliances without supplemental tests with the device(s) applied to the particular appliance design.


    1.1.4

    Each component of a piezo ignition system shall be capable of operation throughout a temperature range of 32°F to 125°F (0°C to 51.5°C). A higher, lower, or both higher and lower temperature may be specified by the manufacturer.


    1.1.5

    If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.


    1.1.6

    All references to psi throughout this standard are to be considered gage pressures unless otherwise specified.


    1.1.7

    Exhibit A contains provisions that are unique to Canada.


    1.1.8

    Exhibit B contains provisions that are unique to the United States.


    1.1.9

    Exhibit C contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.
