9 3.5 maximum oil flow position the maximum oil flow position is the control device setting with the maximum oil flow to the burner 3.6 heating gases heating gases are the combustion gases flowing inside the stove 3.7 minimum oil flow position the minimum oil flow position is the control device setting with the minimum oil flow to the burner 3.8 nominal heating capacity the nominal heating capacity is the heating capacity indicated on the rating plate 3.9 storage tank the storage tank is the part in the stove from which the burner is supplied with fuel 3.10 oil derivatives oil derivatives are the organic substances which are deposited onto the filter paper when determining the smoke number 3.11 oil regulator the oil regulator is a device which ensures an adjustable, constant flow of oil to the burner 3.12 smoke number smoke number (SN) is the degree of blackening which the soot causes on white filter paper under the conditions specified in this standard 3.13 combustion air limiter the combustion air limiter is a device for limiting the combustion air supply 3.14 combustion air conveyor the combustion air conveyor is a device for conveying the combustion air supply 3.15 combustion chamber the combustion chamber is the area in the stove where combustion takes place 3.16 vaporizing burner the vaporizing burner is a burner in which combustion of the fuel occurs under the effect of heat and, together with the combustion air, forms a combustible fuel vapour/air mixture 3.17 heat input the amount of heat supplied by the fuel on an hourly basis to the stove, calculated using the calorific value, H i of the fuel 3.18 heating capacity the heating capacity is the useful amount of heat given off hourly by the stove 7

10 3.19 Efficiency efficiency is the ratio of the actual heating capacity to the related heat input, expressed as a percentage 3.20 ignition device the ignition device is a built-in device for igniting the fuel vapour/air mixture 3.21 content of NO X content of NO X in the dry flue gases measured as volume in ppm, calculated as NO 2, expressed in mg/mj 3.22 content of unburnt Hydrocarbons content of unburnt hydrocarbons in the dry flue gases measured as volume in ppm, calculated as C 3 H 8, expressed in mg/mj 4 Constructional requirements 4.1 Heating capacity The nominal heating capacity, expressed in kilowatts, shall be: selected by the manufacturer; verified during the tests; indicated on the rating plate. The nominal heating capacity shall be rounded off to the nearest multiple of 500 W. 4.2 Materials The quality of the materials as well as the shape and dimensions of the components shall ensure that, provided the operational procedures are met and with the associated mechanical, chemical and thermal stresses which occur, the stoves will remain safe and operable over a given period. The stove shall be fire-resistant and safe to operate, and shall be designed such that no visible deformations following the performance tests according to Clause 6 occur; it can withstand the stresses arising during normal operation; the burner and the stove cannot become heated to create a hazard; dangerous accumulations of combustible gases (fuel mixed with air) in the combustion chamber and in the flues are prevented (for automatically operated burners only); gases cannot leak from the stove in dangerous quantities. The stove shall be made of non-combustible materials except that combustible materials shall be allowed for the following: components of accessories e.g. burner covers, if the parts are fitted outside of the boiler; internal components of controls and safety equipment; operating handles; 8

11 electrical equipment. Component parts of covers, operating, control and safety devices and electrical accessories shall be arranged in such a way that their surface temperatures, under steady state conditions, do not exceed those specified either by the manufacturer or in the component part standard. NOTE Because the entire heat dissipating surfaces of the appliance including the flue spigot/socket and the flue gas connector are working surfaces, there is no requirement for limiting the surface temperature of the appliance. 4.3 Combustion chamber The combustion chamber shall be properly sealed and fitted with a device (e.g. lid, door, etc.) which cannot be locked, and designed to compensate for any excess pressure. 4.4 Filter The stove shall include at least one filter situated either before or inside the oil regulator and a strainer in the filling orifice. The filter shall retain particles with a diameter of over 0,25 mm. The filter and strainer shall be easy to remove and clean. 4.5 Oil regulator Oil regulators, or equivalent devices, shall maintain the flow of oil reaching the burner at a constant value corresponding to the setting selected. The closed and maximum open positions shall each have a limiting stop. The minimum position shall be clearly marked and be sensed as a resistance that can be overcome mechanically. 4.6 Marking of operating settings The control device for the oil regulator shall have clearly visible and permanent markings. 4.7 Safety device The stove shall have a safety device to prevent overflowing of the oil from the burner. 4.8 Fan for the supply of combustion air Irrespective of the operating setting of the stove, the supply of combustion air from the fan shall not create excess pressure in the combustion chamber. The operation of the fan shall be trouble free. The function of the burner shall be linked with that of the fan. In the event of a failure of the fan, the flow of oil to the burner shall be either totally interrupted or reduced to a flow such that the smoke number does not exceed the maximum permissible value for the operation of the burner without the fan. If the fuel supply to the burner is completely cut off by an electric current failure, then for manually operated burners (without automatic ignition), when the current is restored, the fuel shall be readmitted to the burner manually. For automatically operated burners (automatic ignition), when the current is restored, the ignition without a blow-out shall be ensured. 4.9 Fuel lines The fuel lines shall not be load-bearing parts of the construction. The fuel lines shall be resistant to the fuel and shall not exceed the maximum permissible surface temperatures specified by the manufacturer. Removable fuel lines shall be connected by means of metal screw threads including at least four engaged threads. The sealing of the parts containing fuel shall be such 9

12 that there is no leakage or seepage. It shall not be possible to remove any component in the oil supply line to the burner without the use of a tool Storage tank When the stove includes a storage tank, its effective capacity shall enable operation of the stove for at least 10 h in the case of nominal heating capacity < 8 kw and at least 8 h in the case of a nominal heating capacity > 8 kw. The filling orifice of the storage tank shall have a cap. It shall be possible to cut off the supply of fuel from the storage tank to the burner be means of a shut-off device fitted before the oil regulator. If it is a rotary device, closing shall be by turning in a clockwise direction. To ensure that any fire external to the stove is not transmitted to the contents of the built-in storage tank or, if a fire does occur, its effects are limited by either the tank being made of non-combustible materials e.g. metal or be enclosed with non-combustible fire resisting materials or construction. Any fuel lines from the tank to the burner shall also be fire resistant. The filling orifice of the built-in storage tank shall have a cap and shall be easily accessible and it shall be so arranged that when filling the tank with fuel it is not possible to ignite the fuel from any hot components Oil-level indicator Built-in storage tanks shall have an oil-level indicator Drip tray Any stove incorporating a built-in storage tank shall incorporate a drip tray, below the parts of the stove containing fuel, for the collection of any spillage, having an edge height of a least 10 mm (inside depth) and capacity of a least 1 dm³ Flue outlet The flue outlet can be of the push-on or push-in type and shall have a circular cross-section at its end and permit the attachment of a flue gas pipe, the diameter of which compiles with the applicable standards of the country in which the stove is to be installed. It shall be possible to fit a flue pipe, having a diameter D in a length D/4, but at least 30 mm, onto or into the flue outlet Damper Dampers or other movable devices for restricting the flow of flue gases are not permitted Draught regulators and combustion air limiters Draught regulators shall be able to be set in a permanent manner at the maximum draught indicated by the manufacturer. This value shall be given in the installation instructions. Draught regulators and combustion air limiters built into the stove shall be fitted at the manufacturers' works and shall operate automatically. One of these two devices shall be fitted if the stove has no fan for the supply of combustion air. 10
