Preface  

This is the sixth edition of CSA/ANSI Z21.89 • CSA 1.18, Outdoor cooking specialty gas appliances . It supersedes the previous editions published in 2017, 2013, 2007, 2004, and 2002. 

The major changes to this edition include the following: a) Altitude testing requirements have been updated.  b) Battery temperature limits have been revised.  c) Additional requirements for manufacturing and production have been added.  d) Coverage for low temperature operation has been added.  e) Combustible material temperature tolerances have been standardized.  f) Wind testing requirements have been revised.  g) Annex D, on smart enabled appliances, has been added.  h) Annex E, on input calculations, has been added.  i) References to manufactured and mixed gases have been removed.  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 Subcommittee on Standards on Outdoor Cooking and Illuminating 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 Fuel Burning Equipment, 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. 

Scope  

1.1 Applicable equipment  

This Standard applies to newly produced, outdoor cooking specialty gas appliances, hereinafter referred to as “appliances”, constructed entirely of new, unused parts and materials.  Note: Appliances submitted for examination under this Standard are classified as portable or stationary. These products are not intended for commercial use.  

1.2 Applicable equipment for recreational vehicle  

This Standard applies to recreational vehicle gas outdoor cooking appliances.  

1.3 Non-applicable equipment  

This Standard does not apply to  a) appliances for installation in or on a boat;  b) appliances for installation in the interior living space of a recreational vehicle; and  c) fryers/smokers for installation on a recreational vehicle.  

1.4 Outdoor cooking specialty gas appliance  

An appliance can be a  a) fryer;  b) boiler;  c) smoker;  d) tabletop gas grill incorporating an open top broiler, top burner(s), griddle, or any combination;  e) combination of any of the above; or  f) recreational vehicle outdoor cooking specialty gas appliance.  Note: A tabletop gas grill is not a built-in type.  

1.5 Fuel systems  

Appliances can be for connection to  a) a fixed fuel piping system, including a recreational vehicle’s low-pressure liquefied petroleum (LP) gas system; or  b) a self-contained LP gas or propane gas supply system of a single cylinder with a maximum size of 20 lb (9.1 kg) of fuel.  

1.6 Fuel types  

This Standard applies to appliances operating at inlet gas pressures not to exceed 1/2 psi (3.5 kPa) for connection to a fixed fuel piping system for use with  a) natural gas;  b) LP gases; and  c) LP gas-air mixtures. 

1.7 Self-contained systems  

This Standard also applies to appliances designed for connection to a self-contained LP gas and propane gas supply systems (see Clause 4.4)  a) operating at regulated outlet pressures not to exceed 1 psi (6.9 kPa); or  b) operating at regulated outlet pressures in excess of 1 psi (6.9 kPa) but not greater than 10 psi (69 kPa).  Notes:  1) The construction of appliances for use with the above-mentioned gases is covered under Clause 4.  2) The performance of appliances for use with the above-mentioned gases is covered under Clause 5.  

1.8 Pressure references  

Throughout this Standard, gauge pressures are designated in pounds per square inch (psi) and kilopascals (kPa). 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.  

1.9 Measurement units  

The values given in US customary units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only (see Clause 8).  

1.10 LP gas cylinder label  

Annex A contains the LP gas cylinder label.  

1.11 Conversion kits  

Annex B contains provisions for outdoor cooking specialty gas appliance conversion kits.  

1.12 Smart-enabled appliances  

Annex D contains provisions that are applicable to a smart-enabled appliance.  

1.13 Items unique to the United States  

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

1.14 Items unique to Canada  

Clause 8 contains provisions that are unique to Canada.  

1.15 Non-applicable standard  

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

1.16 Terminology  

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.  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.
