Preface

This is the third edition of ANSI Z21.75 / CSA 6.27, Connectors for outdoor gas appliances and manufactured homes. It supersedes the previous editions published in 2007 and 2001.

Scope

1.1
This Standard applies to newly produced assembled connectors constructed entirely of new, unused parts and materials. Such connectors are intended for exterior use above ground for making the following non-rigid connections:

a) between the gas supply and the gas inlet of an appliance for outdoor installation that is not frequently moved after installation. These connectors are not intended for use with wheeled, caster mounted, or portable appliances;

b) between the permanent gas outlet of a manufactured home community (mobile home park) or individual site and the piping inlet on a park trailer or a manufactured (mobile) home; or

c) between sections of a multiple section manufactured (mobile) home.

1.2
Connectors covered by this Standard are considered suitable for use with natural, manufactured, mixed, and propane gases and LP gas-air mixtures.

1.3
Connectors covered by this Standard are for use on piping systems operating at fuel gas pressures not in excess of 1/2 lb/in2 (3.5 kPa).

1.4
Connectors covered by this Standard are to have a nominal length of not less than 1 ft (0.31 m) or more than 6 ft (1.83 m).

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.

1.6
All references to “psi” throughout this Standard are to be considered gauge pressure unless otherwise specified.

1.7
Annex A contains provisions that are unique to Canada.

1.8
Clause 2 contains a list of standards specifically referenced in this Standard and sources from which these reference standards may be obtained.

1.9
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.
