Preface
This is the sixth edition of ANSI Z21.58 • CSA 1.6, Outdoor cooking gas appliances. It supersedes the previous editions published in 2018, 2015, 2007, 2005, and 1995.
The sixth 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) zinc coated steel not exposed to temperatures exceeding 500 °F (260 °C).
b) prohibition of ventilation openings on the front of portable grills;
c) increased ventilation size requirements for built-in grill enclosures;
d) existing coverage of CSA C22.2 No. 60335-2-102 added as alternative to CSA C22.2 No. 3;
e) coverage for low temperature operation of outdoor cooking appliances added;
f) appliances are to be tested at an altitude of less than 2000 ft (600 m) above sea level;
g) calculations updated to more accurately reflect appliance inputs and efficiencies;
h) testing in winds of up to 10 mph extended to operation of burners on low setting; and
i) new Annex B, which permits manufacturers to offer smart enabled appliances.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
This Standard was prepared by the Z21/CSA Joint Technical Subcommittee on Standards for Outdoor Cooking and Illuminating Gas Appliances, under the jurisdiction of the Z21/83 Technical Committee on Performance and Installation of Gas Burning Appliances and Related Accessories, the Technical Committee on Gas Appliances and Related Accessories, and the Strategic Steering Committee on Standards for Fuels and Appliances, and had been formally approved by the Technical Committees and the Interprovincial/Territorial Gas Advisory Council.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.

1.1 Applicable equipment
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 Applicable equipment for recreational vehicle
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 liquefied petroleum (LP) gas supply system (see Clause 1.9).
1.3 Non-applicable equipment
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 Outdoor cooking gas appliance
An outdoor cooking gas appliance might be a
a) broiler unit;
b) top or surface unit;
c) oven of the non-self-cleaning type;
d) combination of Item a), b), or c), or any other outdoor cooking gas appliance; or
e) RV grill.
1.5 Self-cleaning ovens
This Standard does not apply to ovens of the self-cleaning type.
1.6 Fuel systems for non-built in type
Outdoor cooking gas appliances may be for connection to
a) a fixed fuel piping system;
b) a remote self-contained LP 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 Item c) or d) and instructions for installing the mounting and retention means within the built-in enclosure;
c) a self-contained LP 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 80 000 Btu/h (23 446 W) that are designed to accommodate a vertically mounted cylinder with a maximum size of 20 lb (9.1 kg) of fuel; or
ii) outdoor cooking gas appliances with input ratings greater than or equal to 80 000 Btu/h (23 466 W) that are designed to accommodate a vertically mounted cylinder with a maximum size of 30 lb (13.6 kg) of fuel; or
d) a self-contained LP gas supply system with an integral cylinder mounting means for the attachment of not more than two vertically mounted vapour withdrawal cylinders, each with a maximum size of 20 lb (9.1 kg) of fuel for outdoor cooking gas appliances with input ratings greater than or equal to 80 000 Btu/h (23 466 W).

a) natural gas;
b) manufactured gas;
c) mixed gas;
d) LP 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 not exceeding 11 in wc (2.74 kPa) and in excess of 11 in wc (2.74 kPa) but not greater than 5 psi (34.5 kPa).
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.
