Product Details
Preface
This is the harmonized CSA Group and UL standard for particular requirements for Automatic Electrical Burner Control Systems. It is the first edition ANSI Z21.20 - CAN/CSA-C22.2 No. 60730-2-5 and the third edition of UL 60730-2-5. This edition of ANSI Z21.20 - CAN/CSA-C22.2 No. 60730-2-5 replaces the previous edition published in 2007 as ANSI Z21.20 - CSA C22.2 No. 199, Automatic Electrical Controls for Household and Similar Use Part 2: Particular Requirements for Automatic Burner Ignition Systems and Components. This edition of ANSI Z21.20 - CAN/CSA- C22.2 No. 60730-2-5 also replaces CAN/CSA-E730-2-5-94, Automatic electrical controls for household and similar use - Part 2: Particular requirements for automatic electrical burner control systems (adopted IEC 730-2-5:1990). This edition of UL 60730-2-5 supersedes the sixth edition of UL 372, Automatic Electrical Controls for Household and Similar Use - Part 2-5: Particular Requirements for Burner Ignition Systems and Components, and the fifth edition of UL 372, Primary Safety Controls for Gas- and Oil-Fired Appliances. This Standard is based on the Standard for Automatic Electrical Controls for Household and Similar Use, Part 2-5: Particular Requirements for Automatic Electrical Burner Control Systems, IEC Publication 60730-2-5, edition 3.2: 2009. This harmonized standard has been jointly revised on September 30, 2019. For this purpose, CSA Group and UL are issuing revision pages dated September 30, 2019.
In Canada, for general information on the Standards of the Canadian Electrical Code, Part II, see the preface of CAN/CSA-C22.2 No. 0. In Canada, this Standard applies to equipment that is intended to be installed or used in accordance with CSA C22.1, the Canadian Electrical Code, Part I.
This standard has been approved by the Standards Council of Canada (SCC) as a National Standard of Canada.
This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.
Scope
This clause of part 1 is applicable except as follows:
1.1 Replacement:
This part of IEC 60730 applies to automatic electrical burner control systems for the automatic control of burners for oil, gas, coal or other combustibles for household and similar use including heating, air conditioning and similar use.
This part 2-5 is applicable to a complete burner control system and to a separate programming unit. This part 2-5 is also applicable to a separate electronic high-voltage ignition source and to a separate flame detector.
Separate ignition devices (electrodes, pilot burners, etc.) are not covered by this part 2-5 unless they are submitted as part of a burner control system.
Requirements for separate ignition transformers are contained in IEC 60989 .
1.1DV.1 D2 Modification of 1.1 by adding the following text to the note:
Separate ignition devices (electrodes, pilot burners, etc.) are covered by this part 2-5 (Refer to Annex DVKK).
Requirements for separate ignition transformers are covered in Standard for Specialty Transformers, UL 506, and CSA C22.2 No. 13, Standard for Luminous Tube Signs, Oil and Gas Burner Ignition Equipment, Cold-Cathode Interior Lighting.
Throughout this part 2-5, where it can be used unambiguously, the word system' means burner control system and systems means burner control systems.
Systems utilizing thermoelectric flame supervision are not covered by this part 2-5.
1.1DV.2 D2 Modification of 1.1 by adding the following text:
Devices such as thermoelectric flame supervision, pilot burners, oxygen depletion safety shut-off systems (ODS), thermoelectric safety shut-off devices, fast-acting thermocouples, and other components are covered in Annex DVKK.
1.1.1 This part 2-5 applies to the inherent safety, to the manufacturer's declared operating values, operating times and operating sequences where such are associated with burner safety and to the testing of automatic electrical burner control systems used in, on, or in association with, burners.
Requirements for specific operating values, operating times and operating sequences are given in the standards for appliances and equipment.
Systems for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this part 2-5.
This part 2-5 applies to systems using NTC or PTC thermistors, additional requirements for which are contained in Annex J.
This part 2-5 does not apply to systems designed exclusively for industrial applications.
1.1.1DV D2 Modification of 1.1.1 by adding the following text:
This part 2-5 does apply to systems designed exclusively for industrial applications.
1.1.2 This part 2-5 applies to manual controls when such are electrically and/or mechanically integral with automatic controls.
Requirements for manual switches not forming part of an automatic control are contained in IEC 61058-1.
Throughout this part 2-5, the word equipment means appliance and equipment.
1.2 Replacement:
This part 2-5 applies to systems with a rated voltage not exceeding 660 V and with a rated current not exceeding 63 A.
1.2DV DR Modification of 1.2 by adding the following text:
The maximum control output voltage is 600 V. The maximum current is unlimited.
The primary input circuit of a system shall be a two-wire, one-side-grounded system, having a voltage rating of not more than a nominal 120 volts. A switch or protective device shall be in the circuit electrically connected to the ungrounded supply conductor.
1.3 Replacement:
This part 2-5 does not take into account the response value of an automatic action of a control, if such a response value is dependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer applies.
This part 2-5 includes systems responsive to flame properties.
1.4 Replacement:
This part 2-5 applies also to systems incorporating electronic devices, requirements for which are contained in Annex H.
