Full Description

Preface:

This is the third edition of CSA/ANSI Z21.90 CSA 6.24, Gas Convenience Outlets and Optional Enclosures. It supersedes the previous editions published in 2015 and 2001.

The third edition of this Standard has been updated to reflect current industry practice, and address CSA Group's guide on drafting Standards. Major changes to this edition include the following:
a) Clause 4.1.8 has been added for cleaner installation closer to a gas appliance so connections will not be a tripping hazard in patio applications;
b) a reference has been included to the International Fuel Gas Code (IFGC) where the National Fuel Gas Code is referenced within the Standard;
c) the Instructions section has been updated to remove the mandate of including the certification body in the instructions;
d) materials permitted within the Marking section have been clarified; and
e) a method of test has been included for impact strength, corrosion resistance, strength, and load.

Scope:

1.1
This Standard applies to gas convenience outlets, hereinafter referred to as gas outlets and optional enclosures, not to exceed 1-1/2 in (38.1 mm) and pressures not to exceed 5 psi (34.5 kPa), capable of operation at temperatures between 32 F and 200 F (0 C and 93.3 C) if intended for indoor use only, or between 20 F and 200 F (28.8 C and 93.3 C) if intended for indoor/outdoor use. Indoor/outdoor use is also to be capable of operation at 40 F (40 C) when so specified by the manufacturer.

1.2
This Standard sets forth the minimum capabilities, characteristics, and properties that a gas outlet and optional enclosure must possess, at the time of manufacture, in order to be considered suitable for use in a gas piping system. Details of design and manufacture not stated in these requirements, including such design and production tests that will produce gas outlets that meet these requirements, remain the responsibility of the manufacturer.

1.3
All references to pressure throughout this Standard are to be considered gauge pressure, unless otherwise specified.

1.4
This Standard contains SI (Metric) units corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (IEEE/ASTM SI 10 or ISO 80000-1 is used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both, are to be provided.

1.5
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to 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.
