14、REFACE This is the first edition of one of a series of Standards covering minimum requirements for safe operation, acceptable performance, design, construction, manufacture, marking, and testing of oil burning equipment. Xothing in these requirements is to be considered in any way as indicating a me

15、asure of quality beyond compliance with the provisions they contain. Safe and satisfactory operation of oil burning equipment depends to a great extent upon its proper installation. To assure satisfactory and safe operation, equipment complying with the requirements of this Standard should be instal

16、led in accordance with the latest issue of CS-4 Standard B 139, Installation Code for Oil Burning Equipment. Appendices and footnotes appearing in CSA Standards are not considered part of the requirements of the Standards but are included to facilitate their use. This Standard was prepared by the Co

17、mmittee on OiI Burning Equipment under the jurisdiction of the Sectional Committee on Oil Burning Equipment and was formally approved by these Committees and the CSA Technical Council. OTTAWA, MARCH, 1966 NOTE: In order to keep abreust of progress in the industries concerned, CSA fiubiications are s

18、ubjed to periodic review. Su gestians for improvement will be welcomed ut all times. They will be recorch and in due course brought to the attention of the appropriate Committee for consideradian. Also, requests for interpretdon wilE be accepted 6y the Committee. They should be worded in such a mnw

19、as to permit a simple “yes” or “no) answer based on the literal text of tbc requirement concerwd.

SCOPE 1 .l This Standard applies to oil burning assemblies comprising a vapouri

22、zing burner and such devices as may be required to control the supply of fuel to the burner. 1.2 This Standard applies only to oil burner assemblies intended for use with either kerosene, No. 1 or No. 2 fuel oil as classified in CSA Standard B 140.0. 1.3 This Standard applies to oil burner assemblie

23、s which may be installed in vented heating or cooking appliances. 1.4 This Standard applies to burner assemblies with a fuel input rate of one Canadian gallon per hour or less. 1.5 The requirements given herein apply to burner assemblies when installed in accordance with the instructions supplied by

24、 the manufacturer. 1.6 Burner assemblies having a burning rate greater than one Canadian gallon per hour, may be examined and tested in accordance with the intent of these requirements. 2. DEFINITIONS 2.1 The following definitions apply in this Standard: Burner means that portion of the oil burner a

25、ssembly within which the fuel is vapourized and mixed with the combustion air; Burner assembly means a unit comprising a vapourizing burner and such devices as may be required to control the supply of fuel to the burner; CG means cubic centimetre; Manufacturer means the manufacturer responsible for

26、the complete oil burner assembly but does not necessarily manufacture the components thereof; Operating level For a float operated antiflooding device means the level attained in the fuel chamber of the device under a fixed supply head and with the metering valve set to a flow rate of not less than

27、3, or more than 6 cc per minute; For a barometric tank and sump antiflooding device means the level attained in the sump with the fuel in barometric tank at room temperature and with the metering valve set to a flow rate of not less than 3, or more than 6 cc per minute; Vapourizing type oil burner m

28、eans an oil burner in which the fuel oil is vapourized from a film of fuel oil on a surface of the burner by the heat of the burner flame. 8 CSA STANDARD 3140.1 3. GENERAL REQUIREMENTS 3.6 General 3.1.1 The equipment shall meet the general provisions of CSA Standard B 140.0-1963, Definitions and Gen

29、eral Requirements for Oil Burning Equip- ment, applicable to all oil burning equipment. Other references herein t that Standard are abbreviated to CSA Standard B 140.0. 3.8.2 Where a definition or requirement as given in this Standard ap- pears to differ, from the definition or requirement as given

30、in any of the publications referred to in this Standard, the definitions or requirement as given in this Standard shall govern. 3.2 Threads 32.1 Pipe Threads. All pipe threads shall be in accordance with American Standard B2.l-1960, Pipe Threads (Except Dryseal), for tapered pipe threads. 3.2.2 Scre

31、w Threads.

Electrical. features, where incorporated as part of the oiI burner as

32、sembly, shall meet the applicable requirements of the CSA C22.2 Series of Standards (Canadian Electrical Code, Part 11) and in particular CSA Standard C22.2 No. 3-1961, Electrical Features of Fuel- Burning Equipment (Gas and Oil). 4.1 General 4.1.1 The design and construction of the assembly, parts

33、or components shall be in accordance with accepted concepts of safety, substantiality, durability, interchangeability, and workmanship. 4.9.2 Burner assemblies shall be designed to provide reasonable accessibility to components which require periodical servicing and/or adjustment. 4.1.3 Burner assem

34、blies, intended for field installation, shall include suitable means for the adjustment, support, and attachment of components in accordance with the instructions supplied by the manufacturer. 4.1.4 It shall be possible to restore a component which has been removed for servicing to its proper place

35、in relation to other components of the assembly without the necessity of realignment. 4.1.5 Burner assemblies designed for manual ignition shall be provided, where necessary, with a suitable torch. 4.2 Antiflooding Devices 4.2.1 General. Each oil burner assembly shall be equipped with an antifloodin

36、g device, which, when mounted in accordance. with the manu- facturers instructions, shall limit the level of the fuel in the burning unit to a safe maximum as determined by tests specified in Clauses 7 and 8.
