1.1 Scope
1.1.1 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. It applies to newly produced refrigerators constructed entirely of new, unused parts and materials:
(a) For use with natural gas;
(b) For use with manufactured gas;
(c) For use with mixed gas;
(d) For use with liquefied petroleum gases;
(e) For use with LP gas-air mixtures;
(f) For manufactured home (mobile home) installation for use with liquefied petroleum gases only (see 1.2.26);
(g) For manufactured (mobile home) installation convertible for use with natural gas and liquefied petroleum gases when provision is made for the simple conversion from one gas to the other (see 1.2.26);
(h) For recreational vehicle installation for use with liquefied petroleum gases only (see 1.2.17); and
(i) For recreational vehicle installation convertible for use with natural gas and liquefied petroleum gases when provision is made for the simple conversion from one gas to the other (see 1.2.17).
The construction of refrigerators for use with the above-mentioned gases is covered under Part I.
The performance of refrigerators for use with the above-mentioned gases is covered under Part II.
1.1.2 Refrigerators submitted for examination under this standard shall use Group 2 refrigerants in quantities not exceeding 6 pounds (2.7 kg). Group 2 refrigerants include, but are not limited to, the following:
(Refrigerant / ANSI/ASHRAE 34 Designation) Ammonia/717; 1,2-dichloroethylene(trans)/1130; Ethyl chloride/160; Methyl chloride/40; Methyl formate/611; Sulfur dioxide/764.
Refrigerant systems shall comply with the applicable provisions of the Standard Safety Code for Mechanical Refrigeration, ANSI/ASHRAE 15.
1.1.3 A refrigerator submitted for examination under this standard shall be provided with a direct, self-contained type of system employing the absorption or adsorption principle of refirgeration.
1.1.4 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.
1.1.5 This standard also covers all electrical equipment, wiring and accessories built in or supplied with gas-fired refrigerators for use with low-voltage direct current or alternating current. Refrigerators for use with alternating current shall be nominally rated 120 volts, 60 hertz.
1.1.6 Refrigerators for use with gas fuel that are also for use with electricity shall also comply with the applicable provisions of the Standard for Household Refrigerators and Freezers, ANSI/UL 250.
1.1.7 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.
1.1.8 If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.
1.1.9 Exhibit A contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.
