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 for Gas Food Service Equipment, under the jurisdiction of the Technical Committee on Bi-National Gas Appliances and Related Accessories and the Strategic Steering Committee on Standards for Gas Appliances and Related Accessories, and has been formally approved by the Technical Committee. 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 General This Standard applies to newly produced gas food service equipment providing coverage for ranges and unit broilers, baking and roasting ovens, counter appliances, deep fat fryers, kettles, steam cookers, steam generators, tableside cooking appliances (see Clause 3), hereinafter referred to as either "appliances" constructed entirely of new, unused parts and materials for use in food service centres of commercial, industrial, institutional, and public assembly buildings, or "outdoor appliances" constructed entirely of new, unused parts and materials for outdoor use and/or for installation in either carts or trailers. Appliances covered under this Standard are for use with a) natural gas; b) propane gas; c) liquefied petroleum (LP) gases [see Clause 5.2 e)]; d) butane gas (tableside cooking appliance only); e) LP gas-air mixtures; and f) natural gas convertible to either propane gas or LP-gases. Notes: 1) The construction of gas food service equipment for use with the above-mentioned gases is covered under Clause 4. 2) The performance of gas food service equipment for use with the above-mentioned gases is covered under Clause 5. 1.2 Gas inlet pressures The maximum allowable gas inlet pressures for the allowable fuels are as follows: a) natural gas: 10.5 in wc (2.61 kPa); b) propane gas: 13.0 in wc (3.23 kPa); c) LP-gases: 13.0 in wc (3.23 kPa); d) butane gas (tableside cooking appliance only): 13.0 in wc (3.23 kPa); and e) LP gas-air mixtures: 9.0 in wc (2.24 kPa). 1.3 Gas manifold pressures The maximum allowable gas manifold pressures for the allowable fuels are as follows: a) natural gas: 10.5 in wc (2.61 kPa); b) propane gas: 13.0 in wc (3.23 kPa); c) LP-gases: 13.0 in wc (3.23 kPa); d) butane gas (tableside cooking appliance only): 13.0 in wc (3.23 kPa); and e) LP gas-air mixtures: 9.0 in wc (2.24 kPa). 1.4 Conformity of food service appliances to applicable requirements All food service appliances (see Clause 3) conform to the applicable requirements under Clauses 4 and 5. In addition, for requirements specific to the product type, see Clauses 6 to 19. 1.5 Outdoor appliance towing regulations An outdoor appliance includes an appliance that is intended to be towed behind a vehicle. This Standard does not address the issues of road performance or Department of Transportation (DOT) (federal, state, Canadian, or provincial) rules and regulations concerning trailers. 1.6 Permanent gas distribution system in carts and trailers This Standard covers the permanent gas distribution system used in any cart or trailer that is being submitted for evaluation under this Standard. 1.7 LP-gas supply systems This Standard also covers appliances that have an LP supply system including fixed piping systems, self-contained supply systems, and remote cylinders with flexible hose connections. 1.8 Electrical equipment, wiring, and accessories in appliances This Standard also covers all electrical equipment, wiring, and accessories built in or supplied for use with an appliance. It covers only such appliances with electrical equipment, wiring, and accessories that are installed in accordance with NFPA 70 or CSA C22.1, as applicable. 1.9 Electrical appliance sections This Standard also covers appliances with incorporated dedicated electrical cooking sections that are evaluated in accordance with CSA-C22.2 No. 3 or CAN/CSA-C22.2 No. 60335-2-102. 1.10 Portable tableside cooking appliance with a self-contained butane gas fuel supply This Standard also covers a portable tableside cooking appliance equipped with a self-contained butane gas fuel supply with inputs not greater than 15 000 Btu/h (4396 W). Note: A portable tableside cooking appliance is for use by commercial restaurants and may be used indoors, outdoors, or both. The portable tableside cooking appliance covered under this Standard is not for household use. 1.11 Exclusions for mobile structures and appliances This Standard is not intended for appliances that are a) for use in mobile structures with walls on all four sides and a permanent roof; b) separate for mounting on a trailer or cart; or c) carts or trailers that are without appliances. 1.12 Operational voltage This Standard does not limit the voltages allowable for the proper operation of the appliance. 1.13 Items unique to the United States Annex A contains items that are unique to the United States. 1.14 Items unique to Canada Annex B contains items that are unique to Canada. 1.15 List of specifically referenced standards and their sources Clause 2 contains a list of standards specifically referenced in this Standard, and sources from which these reference standards may be obtained. 1.16 Special construction provisions for convertible appliances Special construction provisions applicable to an appliance convertible for use with natural gas and LP-gases are outlined under Clauses 4.9.3, 4.14.1, and 4.39.2 h) ii) and iii). 1.17 Special construction provisions for appliances with an optional conversion kit Special construction provisions applicable to an appliance designed for use with an optional conversion kit are outlined under Annex C 1.18 Terminology In this Standard, "shall" is used to express a requirement, i.e., a provision that the user shall 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. 1.19 Units of measurement 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. Note: IEEE/ASTM SI 10 or ISO 80000-1 can be used as a guide when converting imperial units to metric units. 1.20 Reference to psi in this Standard All references to psi through this Standard are considered gauge pressure unless otherwise specified.
