Preface

This is the thirteenth edition of CAN/CSA-B149.1, Natural gas and propane installation code. It supersedes the previous editions, published in 2000 by the Canadian Standards Association (CSA), in 1995, 1991, 1986, 1980, 1978, 1976, and 1974 by the Canadian Gas Association (CGA), and in 1971, 1966, 1962, and 1958 by the Canadian Standards Association.

1 Scope

1.1 This Code applies to the installation of

(a) appliances, equipment, components, and accessories where gas is to be used for fuel purposes;

(b) piping and tubing systems extending from the termination of the utility installation for natural gas or from the distributor.s propane tank; and

(c) vehicle-refuelling appliances and associated equipment meeting the requirements of a general-purpose appliance to fill a natural-gas-fuelled vehicle.

1.2 This Code does not apply to

(a) marine or pipeline terminals;

(b) petroleum refineries;

(c) gas where used as a feedstock in chemical plants;

(d) utility pipeline distribution and transmission pipelines;

(e) storage and handling of liquefied natural gas or underground reservoirs for natural gas;

(f) the installation of NGV fuel systems, containers, and refuelling stations;

(g) the storage and utilization of compressed natural gas on boats;

1.4 This Code and any Standards referenced in it do not make or imply any assurance or guarantee with respect to the life expectancy, durability, or operating performance of equipment and materials referenced in the Code.

1.5 The values given in yard/pound units are the standard. This Code contains SI (metric) equivalents to yard/pound units so that the Code can be used in SI (metric) units. SI (metric) equivalents may be approximate.

1.6 In this Code, unless approved otherwise by the authority having jurisdiction, "shall" indicates a mandatory requirement; "should" indicates a recommendation or that which is advised but not mandatory; "may" indicates an advisory or optional statement. Notes to the text do not include mandatory or alternative requirements.

1.1 This Code applies to

(a) the storage, handling, and transfer of propane;

(b) the installation of appliances, equipment, components, accessories, and containers on highway vehicles, recreational vehicles, mobile housing, outdoor food service units, and wash-mobiles when propane is to be used for fuel purposes; and

(c) the installation of containers and equipment to be used for propane in distribution locations and filling plants.

1.2 This Code does not apply to

(a) marine or pipeline terminals;

(b) petroleum refineries;

(c) propane when used as a feedstock in chemical plants;

(d) utility pipeline distribution and transmission pipelines;

(e) refrigerated storage or underground reservoirs for propane; (f) propane used on boats;

(g) propane used as a propellent in aerosol containers;

(h) butane fuel cylinders of 5.3 oz (150 g) capacity or less; and

(i) the installation of appliances, equipment, components, accessories, and containers other than those on highway vehicles, recreational vehicles, mobile housing, outdoor food service units, and wash-mobiles when propane is to be used for fuel purposes.

1.3 Where the term "propane" is used, the requirements of this Code include, and apply equally to, any material that is composed predominantly of any of the following hydrocarbons or mixtures of them: propane, propylene, butanes (normal butane or isobutane), and butylenes.

1.4 The values given in yard/pound units are the standard. This Code contains SI (metric) equivalents to yard/pound units so that the Code can be used in SI (metric) units. SI (metric) equivalents may be approximate.

1.5 In this Code, unless approved otherwise by the authority having jurisdiction, "shall" indicates a mandatory requirement; "should" indicates a recommendation or that which is advised but not mandatory; "may" indicates an advisory or optional statement.

B149HB-05

This is the fourth edition of CSA's B149HB, Natural Gas and Propane Code Handbook. It supersedes the previous editions, published in 2000 by CSA and in 1995 and 1991 by the Canadian Gas Association.

1. SCOPE

The scope of this handbook is limited to Clauses 1 through 8, inclusive, of the CSA-B149.1-05 Natural Gas and Propane Installation Code, and selected parts of the CSA-B149.2-05 Propane Storage and Handling Code. The handbook follows the sequence of the B149.1-05 Code from clauses 1. Scope to 8. Venting Systems and Air Supply for Appliances, inclusive. Corresponding requirements from the B149.2-05 Code have been included in this edition so that handbook users are provided with relevant information on requirements governing most typical natural gas and propane installations.

Due to the differences in the physical nature of natural gas and propane, separate requirements are denoted in the Code. These differences between requirements should not be confused in practice.
