ANSI Z21.69-2015 pdf free download.Connectors for moveable gas appliances.
1 Scope 1.1 This Standard applies to newly produced gas appliance connectors constructed entirely of new, unused parts and materials that are intended for use with gas utilization equipment that may be mounted on casters or otherwise be subject to movement. 1.2 Connectors complying with this Standard are considered suitable for use with natural, manufactured, mixed and propane gases, and LP gas-air mixtures. 1.3 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. 1.4 All references to psi throughout this Standard are to be considered gauge pressure unless otherwise specified. 1.5 Annex A contains provisions that are unique to Canada. 1.6 Clause 2 contains a list of standards specifically referenced in this Standard, and sources from which these reference standards may be obtained. 1.7 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user shall satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
3 Definitions The following definitions shall apply in this Standard: Adapter — as used in this Standard, a metal fitting designed to connect standard taper pipe threads to the connector nut. Appliance — all gas utilization equipment. Capacity — as used in this Standard, the amount of a specified gas that will flow through a connector at a specified pressure drop in a fixed period of time. Conduit, gas — the gas passageway of the connector. Connector, gas appliance — a factory-fabricated assembly of gas conduit and related fittings designed to convey gaseous fuel, and used for making connections between a gas supply piping outlet and the gas inlet to an appliance. It is equipped at each end for attachment to standard taper pipe threads. A gas appliance connector is not for vibration isolation. Connectors for Gas Appliances, Z21.24 • CSA 6.10, are not designed for repeated movement after being connected or for repeated disconnecting and connecting, and are not to be used with quick disconnect devices. For installation requiring movement of the appliance on a regular basis, refer to the Standard for Connectors for Moveable Gas Appliances, ANSI Z21.69 • CSA 6.16. Connector, moveable gas appliance — a connector for use with all castered appliances as well as Food Service appliances that may or may not utilize casters and, under conditions of normal use, are moved on a regular basis for service, positioning, or area cleanliness. A connector of this type is not designed for continuous movement and may be equipped with a quick disconnect device. Metal connector — a connector with a gas conduit made entirely of metal. It is not designed for repeated movement after being connected or for repeated disconnecting and connecting.
Corrugated connector — a metal connector having the gas conduit fabricated of metal tubing formed into helical or annular corrugations. Semi-rigid connector — a metal connector having the gas conduit fabricated of semi-rigid metal. Connector, gas hose — a connector designed for use only with portable gas-fired equipment. The gas conduit depends for gastightness on the wall structure of the hose material. The conduit may be supported with internal metal or other reinforcement. The design and application presuppose that the connector will not be pressurized when the appliance served by the connector is not in use. Gas hose connectors include: Gas hose connector for portable indoor gas-fired equipment — a gas hose connector for use only with laboratory, shop, or ironing equipment used indoors that requires mobility during operation.
