Preface
This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of outdoor decorative gas appliances. 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.
Scope
1.1
This standard applies to newly produced gas hose connectors for portable and moveable gas appliances constructed entirely of new, unused parts and materials, consisting of flexible tubing for gas leak resistance that:
(a) Shall be equipped with a male plug fitting which connects to an ANSI Z21.90/CSA 6.24, Gas Convenience Outlets and Optional Enclosures.
(b) Are for use with indoor gas-fired appliances that are portable or frequently moved after installation.
(c) Are for use on piping systems having fuel gas pressure not in excess of 5 psi (34.5 kPa).
(d) Are capable of operation at temperatures between 32?F (0?C) and 200?F (93?C).
(e) Are of 1/4 in to 1-1/2 in nominal internal diameters.
(f) Are of not more than 6 ft (1.83 m) nominal length.
(g) Are equipped with standard taper pipe threads (conforming to the Standard for Pipe Threads, General Purpose (Inch), ANSI/ASME B1.20.1 or the Standard for Dryseal Pipe Threads (Inch) ANSI/ASME B1.20.3) on the end fittings attaching to the appliance and to the gas supply piping.
1.2
Connectors complying with this standard are considered suitable for use with natural, manufactured, mixed 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
Section 7, Items Unique to Canada, contains provisions that are unique to Canada.
1.6
Section 2, List of Reference Standards, contains a list of standards specifically referenced in this standard and sources from which these reference standards may be obtained.
