25、) 3.2 warm air chamber chamber in which the heating inset is installed 4 Classification of appliances Clause 4 of EN 613:2000 applies. 5 Constructional requirements The constructional requirements given in Clause 5 of EN 613:2000 apply with the following modifications: 5.1 General 5.1.6.3 Built-in i

26、nsets Heating insets shall be delivered fully assembled for installation. 5.1.7 Supply of combustion air and evacuation of combustion products 5.1.7.1 General The inset shall be of the type B11BS. It shall include the whole of the combustion circuit, from the entry of the combustion air to the inset

27、 to the combustion products outlet of the inset. 5.1.7.2 Supply of combustion air Combustion air inlets shall have fixed openings and shall be designed such that the requirements concerning combustion and flame stability are met. 5.1.7.3 Draught diverter Heating insets shall have a draught diverter,

28、 which is integral part of the inset. The draught diverter shall be constructed such that in case of spillage the combustion gases shall go directly into the room and not into the warm air chamber. The openings of the draught diverter shall not be adjustable. 5.1.8 Electrical equipment The inset sha

29、ll be so designed and constructed as to obviate hazards of an electrical origin. The inset shall comply with the requirements of EN 50165 which cover such hazards.

30、th electronic components or electronic systems providing a safety function, these shall comply with the relevant requirements of EN 298 with regard to electromagnetic compatibility immunity levels. If the manufacturer specifies the nature of the electrical protection of the inset on the data plate,

31、this specification shall comply with EN 60529 to give the degree of personal protection against contact with dangerous electrical components. 5.2.5 Flame supervision systems 5.2.5.1 General An inset shall have a flame supervision device. It shall control the gas supply to the main burner and to any

32、ignition burner, if fitted. A flame supervision device shall be securely located in relation to every component with which it is designed to operate. In the event of failure of the means of sensing, the inset shall be safe. 5.2.5.2 Insets with thermoelectric safety devices Heat sensitive flame super

33、vision devices of the thermoelectric type shall comply with EN 125. 5.2.5.3 Insets with automatic burner systems If an inset is fitted with an automatic burner control system, it shall comply with EN 298. The manufacturer shall specify the safety time (see 6.10.2.2 of EN 613:2000). For insets above

34、10 kW, the safety time shall not be more than 5 s, and for those up to and including 10 kW, the safety time shall not be more than 10 s. NOTE The safety times have been limited because this inset is installed within a secondary enclosure. Upon flame failure during the running condition the flame sup

35、ervision device shall cause non-volatile lock-out, except in the case of insets with direct ignition of the main burner, in which case: a) spark restoration within 1 s is allowable, or b) a single restart attempt is allowed within 10 s. In the event that re-ignition is unsuccessful during either of

36、these periods non-volatile lock-out shall occur. The operation of push buttons, switches etc., incorrectly or out of sequence shall not adversely affect the safety of an automatic burner control system. 5.2.7 Automatic burner control system This subclause is covered by the final paragraph of 5.2.5.3

37、 above. 5.2.10 Manually operated devices This subclause is covered by 5.2.5.3 above.

38、perational requirements given in Clause 6 of EN 613:2000 apply with the following modifications: 6.4.3 Temperature of floor The inset manufacturer shall provide in his installation instructions the necessary information for either insulating the walls and/or floors or indicating the required clearan

39、ce distances to ensure that the temperature of any adjacent walls and/or floors constructed of non-combustible or combustible materials comply with the following requirements. 6.4.3.1 Insets to be installed on/against non-combustible surfaces For insets intended to be installed in accordance with th

40、e inset manufacturers installation instructions on, or against, non-combustible surfaces, when tested as described in 7.4.3, the temperature at any user touchable point of the floor on which an inset is to be placed shall not exceed the ambient temperature by more than 80 K. 6.4.3.2 Insets to be ins

41、talled on/against combustible surfaces For insets intended to be installed in accordance with the inset manufacturers installation instructions on, or against, combustible surfaces, when tested as described in 7.4.3, the temperature at any point of any floor on which an inset is to be placed, shall

42、not exceed the ambient temperature by more than 60 K. 6.9 Spillage monitoring system Only 6.9.2 of EN 613:2000 applies. 6.11 Efficiency When the inset is tested as described in 7.11, the minimum net efficiency obtained (see 7.11.2 of EN 613:2000) with the inset operating at its nominal heat input sh

43、all be 89 %. 7 Test methods The test methods given in Clause 7 of EN 613:2000 apply with the following modifications: 7.1.5.3 Test installation The appliance shall be installed in accordance with the manufacturers instructions without installing it into the warm air chamber (the requirements of 8.2.

44、2.2 have not to be taken into account). 7.4 Temperature of various parts of the inset For the tests according to 7.4.1 to 7.4.3 the inset is installed according to the manufacturers instructions onto a test rig including all convection air ducts; the heat-resistant casing is replaced by a suitable h

45、eat insulation (see Figures 2 to 6). If the manufacturer requires a certain heat insulation or safety distances to combustible parts of floors or walls, these specifications shall be respected.

46、E) 8 The test rig consists of a plywood board with a thermal conductivity of 0,15 W/mK and their internal surfaces coated with matt black paint (see Figures 2 to 6). Thermocouples are incorporated into each panel (sides and hearth) at the centre of squares of side 100 mm (see Figure 5); these thermo

47、couples are situated in the test panels according to Figure 6. The distance between the back and side surfaces and test panels are the minimum distances specified by the manufacturer or, where appropriate, that distance created by fixing to the wall. The side panel is placed at the side of the inset

48、 where the temperatures are the highest. All measurements are taken when the difference between the surface temperature and the ambient temperature is constant. 7.4.3 Temperature of floor and walls For an inset which is intended to be installed on a combustible surface, the manufacturer should indic

49、ate in the installation instructions the nature of the effective protection to be applied between the inset and the floor, shelf or walls. This protection shall be supplied to the test laboratory by the manufacturer. The inset is adjusted to nominal heat input according to 7.1.3.2 of EN 613:2000 using a reference gas and is operated until thermal equilibrium is achieved. The test is repeated with the inset fan, if any, inoperative. 7.9 Spillage monitoring system The test is carried out according to 7.9.1 and 7.9.3 of EN 613:2000. 7.11 Efficiency The test
