CSA ANSI Z21.24-2015 Connectors for gas appliances

CSA ANSI Z21.24-2015 Connectors for gas appliances. Connector, moveable gas appliance (ANSI Z2.1.69 • CSA 6.16) — 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. Connector nut — a threaded nut permanently attached to a connector conduit which mates with an adapter or gas valve to form a union joint. Listed — equipment or materials included in a list published by a nationally recognized testing laboratory, inspection agency, or other organization concerned with product evaluation that maintains periodic inspection of production of listed equipment or materials, and whose listing states either that the equipment or material meets nationally recognized standards or has been tested and found suitable for use in a specified manner. Non-displaceable rotor member — a valve member that cannot be moved from its seat by a force applied to the valve handle, or force applied by a plane surface to any exterior portion of the valve. Propane — a liquefied petroleum gas that is classified as either “commercial propane” or Special-Duty” propane in accordance with ASTM 01835, Standard Specification for Liquefied Petroleum (LP) Gases. Special-Duty propane is equivalent to Propane HD-5. Propane HD-5 — propane that complies with the same requirements as “Special-Duty” propane, as defined in ASTM 01835, Standard Specification for Liquefied Petroleum (LP) Gases. Protective coating — as used in this Standard, material applied to the exterior surface of the connector to enhance resistance to corrosive materials. Tubing — as used in this Standard, the material from which the gas conduit of a connector is fabricated. Union — an assembly of parts to facilitate connection or disconnection between the connector and gas piping without rotation of the connector tubing. Union, ground joint — a union consisting of three parts (nut, swivel, and end piece) concentrically machined to provide alignment. Valve, appliance connector — a manually operated valve having a non-displaceable moveable valve member, a minimum specified capacity (code marked on the valve), a taper pipe thread inlet, and an outlet for flared tubing connection. An appliance connector valve is intended to be used between the gas supply piping and the appliance connector attached to...
