13、quirements and associated methods of test for gas-fired convector heaters burning 1st, 2nd and 3rd family gases. Since 1974, discussions have been proceeding in the Technical Committee CEN/TC 62 of the European Committee for Standardization towards a harmonized European standard for gas-fired convec
14、tor heaters; however, it has not yet proved possible for this European standard to be agreed and it has therefore been decided that this Part of BS 5258 should be published. While the requirements and methods of test given in this Part of BS 5258 follow existing UK practice, they are in no way inten
15、ded to prejudice UK participation in European standardization or the implementation of any resultant European standard or Harmonization Document of which the UK approves. Requirements for the safety and performance of 1st family gas convector heaters were previously given in BS 1250-1 and BS 1250-4
16、while those for 3rd family appliances were given in BS 2773; these standards have now been withdrawn and the relevant safety requirements, revised where necessary, have been incorporated in this Part of BS 5258 together with requirements for 2nd family appliances. Where technically appropriate, the
17、requirements have been harmonized with other Parts of BS 5258. Thermal performance requirements for these appliances are the subject of BS 6332-4. In common with other Parts of BS 5258 currently being revised, this Part can be applied to all production appliances through a recognized scheme of quali
18、ty assurance, whereas earlier Parts were written with type approval in mind. The intention is that all appliances manufactured in accordance with this standard will be safe in normal use when installed and maintained in accordance with the relevant British Standard codes of practice and with the man
19、ufacturers instructions. Furthermore, such servicing as may be necessary to maintain the appliance in a safe condition should be able to be carried out by a competent fitter without difficulty. The codes of practice relevant to this Part of BS 5258 are BS 5440-1 and BS 5440-2, BS 5871 and BS 5482-1,
20、 BS 5482-2 and BS 5482-3. Attention is drawn to the requirements of the Gas Safety (Installation and Use) Regulations, Electrical Equipment Safety Regulations, Heating Appliances (Fireguards) Regulations and various Building Regulations. The following Parts of BS 5258 are already published or are, a
21、s indicated by an asterisk, in preparation. Part 1: Central heating boilers and circulators; Part 2: Cooking appliances; Part 4: Fanned-circulation ducted-air heaters; Part 5: Gas fires; Part 6: Refrigerators and food freezers; Part 7: Storage water heaters; Part 8: Combined appliances: gas fire/bac

General 1 Scope This Part of BS 5258 specifies safety requirements and describes associated methods of test for
27、domestic gas-fired convector heaters having an input rating not exceeding 25 kW and of the following flue types: a) open-flued (natural draught and fan-powered); b) balanced-flued (natural draught and fan-powered); c) Se-duct. In specifying requirements for appliances burning 2nd family gases it is
28、assumed that a meter governor will be fitted and for appliances burning 3rd family gases it is assumed that the gas supply from the container will be governed by a pressure regulator complying with BS 3016. The requirements for controls relate to controls fitted as part of, or supplied with, particu
29、lar appliances; they do not necessarily provide a complete specification for controls intended for general use. This Part of BS 5258 is not applicable to: 1) flueless appliances; 2) the special requirements for appliances with premixed gas and air burners; 3) type C2 appliances burning 3rd family ga
30、ses (these appliances are not manufactured at present); 4) appliances that incorporate their own butane container. NOTEThe titles of the publications referred to in this standard are listed on the page 30. 2 Definitions For the purposes of this Part of BS 5258, the definitions given in BS 1179:1967,
31、 BS 1179-6 and in the relevant British Standard codes of practice apply, together with the following. 2.1 adjustment pressure the pressure, measured at the test point, that is required to obtain the rated heat input using the reference test gas 2.2 rated heat input the manufacturers declared heat in
32、put for the appropriate reference test gas 2.3 setting pressure the pressure, measured at the test point, that is specified by the manufacturer for the purpose of adjusting the appliance heat input 2.4 cold condition a condition of the appliance required for some tests and obtained by allowing the u
33、nlit appliance to attain equilibrium at room temperature 2.5 hot condition a condition of the appliance required for some tests and obtained by heating to thermal equilibrium at the adjustment pressure, any thermostat remaining fully open 2.6 equivalent length the length of straight flue whose resis
34、tance to flow of products of combustion is equal to that of the actual flue 2.7 limits of tolerance of supply voltage 0.90 times the minimum rated voltage and 1.10 times the maximum rated voltage of the appliance 3 Classification of appliances 3.1 Classification by category The category system of ap
35、pliance classification is described in A.1.3 of BS 4947:1984 by which an appliance is denoted by a category number, I, II or III, according to the number of gas families that it is designed to burn and the families are identified by subscripts T, N and L for the 1st, 2nd and 3rd gas families respect
36、ively. For the purposes of this Part of BS 5258, the following categories of appliances are permitted. a) Categories IT, IN, IL, IL/B, and IL/P b) Categories IITN, IINL, IINL/B, and IINL/P c) Categories III, IIITNL/B, and IIITNL/P 3.2 Classification by flue type For the purposes of this Part of BS 5
37、258, appliances are also classified into the following types according to the flue system for which they are designed and the source of the combustion air. a) Type A: flueless appliances. b) Type B: open-flued appliances. These comprise the following. 1) Natural draught appliances. 2) Fan-powered ap
38、pliances with draught diverter. Licensed Copy: sheffieldun sheffieldun, na, Mon Dec 04 16:22:42 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5258-13:1986 2 BSI 03-1999 These appliances use a fan to move air for combustion and products of combustion through the combustion chamber and heat exchanger.
39、 The draught diverter is connected to a secondary flue in accordance with relevant codes of practice for construction and termination. Examples are shown in Figure 1(a) and Figure 1(b). 3) Fan-powered appliances without draught diverter. These appliances use a fan to move air for combustion and prod
40、ucts of combustion through the combustion chamber, heat exchanger and the flue system. Examples are shown in Figure 2(a) and Figure 2(b). 4) Fan-powered appliances with integral fan in the secondary flue. The flow of air for combustion and products of combustion through the appliance is produced by
41、natural convection. The appliance is fitted with a draught diverter or suitable flue break and a fan in the secondary flue is used to evacuate the products of combustion through the flue. Examples are shown in Figure 3(a) and Figure 3(b). c) Type C: room-sealed appliances. These comprise the followi
42、ng. 1) Type C1: balanced-flued appliances, which may be either natural draught or fan-powered. Fan-powered type C1 appliances will usually be as shown in Figure 4(a) and Figure 4(b). Alternative arrangements of air intake and products outlet ducts to those shown will occur in practice. 2) Type C2: S
43、e-duct appliances. NOTE 1The definitions of these types of appliances are given in BS l179-6. NOTE 2This Part of BS 5258 does not cover type A appliances or type C2 appliances burning 3rd family gases. 4 General requirements The appliance shall comply with this Part of BS 5258 when tested using the
44、specified test gases of the appropriate gas family. Full details of the test gases are given in BS 4947.
