scope:

This Standard covers gas-fired refrigerators having refrigerated spaces for

(1) storage of foods, or

(2) storage of foods and making ice, or

(3) storage of frozen foods and making ice, or (4) storage of foods and the storage of frozen foods and making ice, hereinafter referred to as refrigerators or appliances. The Standard applies to newly produced refrigerators constructed entirely of new, unused parts and materials:

a) for use with natural gas;

b) for use with liquefied petroleum (propane) gases;

c) convertible for use with natural gas and liquefied petroleum (propane) gases for residential use;

d) for manufactured home (mobile home) installation for use with liquefied petroleum (propane) gases only (see Clause 4.1.18);

e) for manufactured (mobile home) installation convertible for use with natural gas and liquefied petroleum (propane) gases when provision is made for the simple conversion from one gas to the other (see Clause 4.1.18);

f) for recreational vehicle installation for use with liquefied petroleum (propane) gases only (see Clause 4.1.19); and

g) for recreational vehicle installation convertible for use with natural gas and liquefied petroleum (propane) gases when provision is made for the simple conversion from one gas to the other (see Clause 4.1.19).

The construction of refrigerators for use with the above-mentioned gases is covered under Clause 4, Construction.

The performance of refrigerators for use with the above-mentioned gases is covered under Clause 5, Performance. Definitions are covered in Clause 3.

This Standard also covers all electrical equipment, wiring and accessories built in or supplied with gasfired refrigerators for use with low-voltage direct current or alternating current. Appliances for use with alternating current shall be nominally rated 120 V, 60 Hz. 1.3

Refrigerators for use with gas fuel that are also for use with electricity shall also comply with the applicable provisions of the Canadian Electrical Code, Part II, CSA C22.2 and the Standard for Household Refrigerators and Freezers, CSA C22.2 No.63/UL 250.

This Standard applies to those refrigerators provided with a direct, self-contained type of system employing the absorption or adsorption principle of refrigeration.

This Standard applies to those refrigerators that are designed to use Group 2 refrigerants in quantities not exceeding 6 lb (2.72 kg). Group 2 refrigerants include, but are not limited.

Note: Refrigerant systems shall comply with the applicable provisions of the Mechanical Refrigeration Code CSA B52, and the Safety Standard for Mechanical Refrigeration, ASHRAE 15. 

A direct vent refrigerator anticipated by this standard is a design option of the manufacturer and is an essentially balanced flue appliance, with the air intake and vent outlet in proximity. Other direct vent designs shall be subjected to such additional tests as believed necessary at the discretion of the testing agency. 

Unless otherwise indicated on its rating plate, a refrigerator is for installation indoors in accordance with its marking and the manufacturer's installation instructions. When specified additional or alternate provisions are met, a refrigerator may be installed in a manufactured home (mobile home) or recreational vehicle. 

This Standard contains SI (Metric) units corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (IEEE/ASTM SI 10, American National Standard for Metric Practice, or ISO 80000-1:2009, Quantities and units - Part 1: General, 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, are to be provided. 

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.

All references to psi throughout this standard are to be considered gauge pressure unless otherwise specified. 

Annex A contains provisions that are unique to Canada. 1.12 Annex B contains provisions that are unique to the United States.
