This Standard applies to newly produced outdoor cooking gas appliances (see Clause 3) constructed entirely of new, unused parts and materials. Outdoor cooking gas appliances submitted for examination under this Standard are classified as portable, stationary, or built-in.

1.2

This Standard applies to outdoor cooking gas appliances mounted to the exterior of a recreational vehicle (RV grills) (see Clause 3) for connection to the recreational vehicle’s low pressure LP gas supply system (see Clause 1.8).

1.3

This Standard does not apply to outdoor cooking gas appliances for installation in or on boats. It does not apply to outdoor cooking gas appliances for installation in the interior living space of a recreational vehicle

1.4

An outdoor cooking gas appliance may be a

a) broiler unit;

b) top or surface unit;

c) oven of the non self-cleaning type;

d) combination of a), b), or c) above, or any other outdoor cooking gas appliance; or

e) RV grill.

 

Rationale: Editorial to remove requirement from Definitions section and relocate to Scope.

1.5

This Standard does not apply to ovens of the self-cleaning type (see Clause 3).

1.6

Outdoor cooking gas appliances may be for connection to

a) a fixed fuel piping system;

b) a remote self-contained liquefied petroleum gas supply system (see Clause 3), provided that the appliance is supplied with remote mounting and retention means for the attachment of a single cylinder with a maximum size in accordance with Clause 1.6 c) or d) and instructions for installing the mounting and retention means within the built-in enclosure;

c) a self-contained liquefied petroleum gas supply system with an integral cylinder mounting means, for attachment to a single cylinder with the following specifications

i) outdoor cooking gas appliances with input ratings less than 23 446 W (80 000 Btu/h) that are designed to accommodate a vertically mounted cylinder with a maximum size of 9.1 kg (20 lb) of fuel; or

ii) outdoor cooking gas appliances with input ratings greater than or equal to 23 466 W (80 000 Btu/h) that are designed to accommodate a vertically mounted cylinder with a maximum size of 13.6 kg (30 lb) of fuel; or

 

d) a self-contained liquefied petroleum gas supply system with an integral cylinder mounting means for the attachment of not more than two vertically mounted vapor withdrawal cylinders, each with a maximum size of 9.1 kg (20 lb) of fuel for outdoor cooking gas appliances with input ratings greater than or equal to 23 466 W (80 000 Btu/h).

1.7

This Standard applies to outdoor cooking gas appliances operating at inlet gas pressures not exceeding 3.4 kPa (1/2 psi4) for connection to a fixed fuel piping system for use with

a) natural gas;

b) manufactured gas;

c) mixed gas;

d) liquefied petroleum gases; and

e) LP gas-air mixtures.

This Standard also applies to outdoor cooking gas appliances designed for connection to self-contained LP gas supply systems (see Clause 4.5) operating at regulated outlet pressures

a) not exceeding 2.74 kPa (11 in wc); and

b) in excess of 2.74 kPa (11 in wc) but not greater than 34.5 kPa (5 psi).

The construction of outdoor cooking gas appliances for use with the above-mentioned gases is covered under Clause 4.

The performance of outdoor cooking gas appliances for use with the above-mentioned gases is covered under Clause 5.

1.8

Built-in outdoor cooking gas appliances may be for connection to

a) a fixed fuel piping system; or

b) a remote self-contained liquefied petroleum gas supply system (see Clause 3), provided that the appliance is supplied with remote mounting and retention means for the attachment of a single cylinder with a maximum size in accordance with Clause 1.6 b) and instructions for installing the mounting and retention means within the built-in enclosure.

1.9

An outdoor cooking gas appliance conforming to Clause 1.6 c) ii), and that is capable of accepting either a 9.1 kg (20 lb) or a 13.6 kg (30 lb) LP gas cylinder, should have all applicable tests in Clauses 4 and 5 conducted with both size cylinders.

1.10

An outdoor cooking gas appliance having integral mounting and retention means should be designed so a spare 9.1 kg (20 lb) or 13.6 kg (30 lb) LP gas cylinder cannot be stored within any enclosure, or under the firebox of the appliance.

1.11

Throughout this Standard, gauge pressures are designated in pounds per square inch (psi) and kilopascals (kPa). Use of the terminology “psig” is not used. Where “psi” is used, it is understood to be pound per square inch gauge. Absolute pressures are not used in this Standard.

1.12

Clause 7 contains provisions that are unique to the United States.

1.13

Clause 8 contains provisions that are unique to Canada.

1.14

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

1.15

An outdoor cooking gas appliance covered by this Standard need not comply with the provisions of CAN1-2.21.

1.16

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.
