1 Scope
1.1 CSA ANSI Z21.58 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). It does not apply to outdoor cooking gas appliances for installation in the interior living space of a recreational vehicle.
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, Definitions), provided 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 1.6c) or Clause 1.6d) 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:
i) outdoor cooking gas appliances with input ratings less than 80,000 Btu/h (23,446 W) shall be designed to accommodate a vertically mounted cylinder with a maximum size of 20 Ib (9.1 kg) of fuel.
ii) outdoor cooking gas appliances with input rating greater than or equal to 80,000 Btu/h (23,466 W) shall be designed to accommodate a vertically mounted cylinder with a maximum size of 30 Ib (13.6 kg) of fuel.
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 20 Ib (9.1 kg) of fuel for outdoor cooking gas appliances with input ratings greater than or equal to 80,000 Btu/hr (23,466 W).
1.12 This Standard contains SI (Metric) equivalents to the yard/pound quantities, the purpose being to allow the Standard to be used in SI (Metric) units. (EEE/ASTM SI 10, American National Standard for Metric Practice, or ISO 80000-1:2009, Quantities and units - Part 1: General (Standard for use of the International System of Units (SI): The Modern Metric System, IEEE/ASTM SI 10 or ISO 80000-1:2009 Quantities and units一Part 1: General are 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 shall are to be provided.CSA ANSI Z21.58 pdf download.
