      Preface


      This is the harmonized CSA Group and UL standard for Automatic electrical controls – Part 2-5: Particular requirements for automatic electrical burner control systems. It is the second edition of CSA/ANSI Z21.20 • CSA C22.2 No. 60730-2-5 and the fourth edition of UL 60730-2-5. This edition of CSA/ANSI Z21.20 • CSA C22.2 No. 60730-2-5 supersedes the previous edition published in 2014 as ANSI Z21.20 • CAN/CSAC22.2 No. 60730-2-5 and replaces ANSI Z21.20-2005, Automatic Gas Ignition Systems and Component, ANSI Z21.20a-2008, Automatic Gas Ignition Systems and Components – Addenda A, CAN/CSA-C22.2 No. 199-89, Combustion safety controls and solid-state igniters for gas-and oil-burning equipment and CAN1-6.4-M79, Automatic Gas Ignition Systems and Components. This edition of UL 60730-2-5 supersedes the previous edition published in 2014 and replaces 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 IEC Publication 60730-2-5, edition 4.2, Automatic electrical controls – Part 2- 5: Particular requirements for automatic electrical burner control systems, issued January 2021. IEC publication 60730-2-5 is copyrighted by the IEC.


      This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of Industry Associations are gratefully acknowledged.


      This standard is considered suitable for use for conformity assessment within the stated scope of the standard.


      This Standard was reviewed by the Z21/CSA Joint Subcommittee on

      Standards for Automatic Gas Controls, under the jurisdiction of the CSA Z21/83 Technical Committee on Performance and Installation of Gas-Burning Appliances and Related Accessories, the CSA Technical Committee on Gas Appliances and Related Accessories, and the CSA Strategic Steering Committee on Fuels and Appliances. It was also reviewed by the CSA Subcommittee on Automatic Controls for Household Use, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety. It has been formally approved by the CSA Technical Committees and the Interprovincial/Territorial Gas Advisory Council. This standard has been developed in compliance with the 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 and normative references


      This clause of Part 1 is applicable except as follows:


      1.1 Scope


      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 intended to be used


      • for household and similar use,


      • in shops, offices, hospitals, farms and commercial and industrial applications.


      This International Standard is applicable


      • to a complete BURNER CONTROL SYSTEM,


      • to a separate PROGRAMMING UNIT,


      • to a separate electronic high-voltage IGNITION SOURCE,


      • to a separate FLAME DETECTOR and


      • to a separate HIGH-TEMPERATURE OPERATION (HTO) DETECTOR.


      • to a BURNER CONTROL SYSTEM intended to be used in warm air heating appliances (furnaces) where the appliance is equipped with an electromechanical differential pressure control to monitor the difference of the combustion air pressure (Type 2.AL). This pressure control provides a switch as an alternative to one of the two switching elements to directly de-energize the safety relevant terminals.


      NOTE 1 Throughout this document, where it can be used unambiguously, the word system means burner control system and systems means burner control systems.


      NOTE 2 Throughout this document, the word equipment means appliance and equipment.


      This standard does not apply to thermoelectric flame supervision controls; thermoelectric flame supervision controls are covered by ISO 23551-6.


      This document also applies to electrical BURNER CONTROL SYSTEMS intended exclusively for industrial process applications e.g. those applications covered by ISO TC 244 (ISO 13577).


      This document applies to controls powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.


      1.1DV.1 D2 Modification of 1.1 of the Part 2 by adding the following:


      Components of burner control systems such as electrodes, flame supervision, oxygen depletion safety shut-off systems (ODS), thermoelectric safety shut-off devices, pilot burners, thermocouples, fast-acting thermocouples, and other components are covered by this Part 2-5. (Refer to Annex DVKK.)


      1.1DV.2 D2 Modification of 1.1 of the Part 2 by adding the following note:


      NOTE 3DV Requirements for separate ignition transformers are covered in UL 506 and CSA C22.2 No. 13.


      1.1DV.3 DE Modification of 1.1 of the Part 2 by adding the following:


      In Canada, this Standard applies to equipment that is intended to be installed or used in accordance with CSA C22.1, Canadian Electrical Code, Part I. In Canada, general requirements applicable to these products are provided in CSA C22.2 No. 0.


      1.1.1 This document applies to the inherent safety, to the 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.


      NOTE Requirements for specific OPERATING VALUES, OPERATING TIMES and OPERATING SEQUENCES are given in the standards for appliances and equipment.


      1.1.2 This document applies to AC or DC powered systems with a rated voltage not exceeding 660 V AC or 600 V DC.


      1.1.3 This document 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 equipment standard or as determined by the manufacturer applies.


      1.1.4 This document applies also to systems incorporating ELECTRONIC DEVICES, requirements for which are contained in Annex H.


      1.1.4DV D2 Modification of 1.1.4 of the Part 2 by adding the following:


      This Standard also applies to manufacturing and production testing (see Annex DVLL) and solid-state oil igniters (see Annex DVMM).


      1.1.5 This document applies to systems using NTC or PTC thermistors, additional requirements for which are contained in Annex J.


      1.1.6 This document includes systems responsive to flame properties and temperature for HTO.


      1.1.7 This document applies to the electrical and functional safety of controls capable of receiving and responding to communications signals. The signals may be transmitted to or received from external units, connected wired or wireless, that may or may not be part of the burner control system.


      1.1.8 This document does not address the integrity of the output signal to the network devices, such as interoperability with other devices, unless it has been evaluated as part of the control system.
