1 Scope This European standard specifies the design, safety and marking requirements and test methods for flueless patio heaters for outdoor or amply ventilated area use only. Although they are not covered by this standard, the requirements of this standard are applicable to appliances that may be used inside habitations which, in addition, shall have a heat input not exceeding 4,2 kW and comply with EN 449. These appliances are for use exclusively with gases of the third family as defined in Clause 4. This European standard applies to appliances that have a nominal heat input not exceeding 17 kW (based on the gross calorific value);  fixed or,  movable, including those which comprise a housing for a transportable and rechargeable liquefied petroleum gas cylinder. This European standard does not apply to appliances equipped with a fan for either combustion or circulation of the convection air. This European standard does not cover LPG containers for liquefied petroleum gas, neither their associated regulator nor tubing and flexible hoses which shall comply with national requirements in force. This European standard does not lay down any specific requirements for the thermal efficiency of this type of appliances, but the requirements relating to combustion, which is a safety matter, ensure that the gas fuel will burn efficiently. However a method to measure the performance is described in informative Annex C. This standard does not apply to appliances covered by EN 416-1, EN 419-1, EN 449, EN 461 and EN 521. This European standard only covers type testing. Items relating to quality assurance systems, production testing and particularly certificates of conformity of auxiliary equipment are not covered by this European standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

9 4 Classification and designation The appliances covered by this European Standard belong to 3rd family gas categories defined in 6.1.2.3 of EN 437:2003. For national situations see Annex A. 5 Design requirements 5.1 General Unless otherwise specified, the design requirements shall be verified by examining the appliance and its operating instructions. Depending on their operating height, and according to table 1 the patio heaters: - shall not exceed the nominal heat input stated; - shall be fitted with one or two grids to protect against accidental contact respectively with working surface and/or reflector. For adjustable appliances the minimum operating position shall be considered. Table 1 – Nominal heat input and protection grids relating to the height of the appliance Minimum operating height : h m Maximal nominal heat input kW (Hs) a Grid required to prevent from contact with the working surface a (see 5.7.6) Grid required to prevent from contact with the reflector b (see 5.10) h ≤ 1,3 6 YES YES 1,3
< h ≤ 1,6 10 YES YES 1,6
< h ≤ 2,0 15 YES NO h > 2,0 17 NO NO a
The height h to be considered is the height of the lower rim of the working surface from the ground. b The height h to be considered is the height of the lower rim of the reflector from the ground. NOTE: For appliances to be fixed on a table the height h is the sum of the heights of the table and the appliance.
5.2 Suitability for various gases The appliance shall be delivered for operation with only one category of gas and for only one operating pressure or pressure combination. Operation with another category of gas or pressure or pressure combination shall not be allowed. No provision shall be made for adjusting any part of an appliance which has been pre-set by the manufacturer. 5.3 Materials The quality and thickness of the materials used for the construction of an appliance shall be such that the performances are not impaired during use. In particular, all components of the appliance shall be capable of withstanding any mechanical, chemical and thermal effects to which they may be subjected during use. Under normal operating, cleaning and adjustment conditions, the materials shall not suffer any permanent distortion which could impair proper operation. Metal parts shall be effectively protected against corrosion.

11 Soundness of shut-off devices or threaded elements of the gas circuit shall be ensured by mechanical means (for example, metal seals, O-rings, etc.), i.e. excluding the use of sealing materials in the thread. However, for those parts which do not require dismantling during normal maintenance, for example valves, injectors, the use of suitable sealing materials in the thread conforming with EN 751 serial standards shall be acceptable. Sealing materials according to EN 549 shall not be subject to ageing, nor to any deformation (reduction or increase in volume) likely to impair safety under normal operating conditions. None of the sealing joints in the gas circuit shall be made by soft soldering or any other process in which the lowest temperature of the melting range is below 450 °C. Parts which can be dismantled shall remain leakproof after dismantling and reassembly, and after possible replacement of the seal if specified in the operating instructions. Sealing washers, according to EN 549, and hoses, made of non metallic materials, shall be suitable for their intended use, specially concerning their resistance to LPG and the temperatures encountered during the use of the appliance. Any tube or flexible hose complying with a recognised standard, used under its approved service conditions and according to the national regulations in force may be used. Depending on the various national situations (see Annex A) the end of the supply pipework shall be fitted either with: - a nozzle allowing the connection of a tubing; the nozzle may be fixed or removable; - a fixed or removable cylindrical, smooth and clean part, at least 30 mm long allowing connection by means of a gastight compression fitting; - a thread in accordance with EN ISO 228-1:2003 or ISO 7-1:1994. During normal conditions of use connections shall not come loose unintentionally. Tubing or flexible hose of the length recommended by the manufacturer and connected in accordance with the instructions, shall not come into contact with a part of the appliance whose temperature is higher than that guaranteed by the tubing or flexible hose manufacturer. Disconnection of the internal piping is acceptable for the purpose of assembling or installing the appliance, provided the installation instructions mention the precautions to be taken when performing this operation in particular to ensure that the gas circuit remains leak-proof. 5.7 Burner 5.7.1 Burner design The burner position shall be fixed in relation to the body of the appliance; it shall not be possible to reassemble it in a position other than that intended by the manufacturer. The component materials of the burner shall be such that the burner is not liable to melting, deformation or damage which could impair its normal operation, even after the induced internal combustion test defined in 7.3.3.1. 5.7.2 Injector The injector shall be non adjustable and, if it can be disassembled, shall be marked. 5.7.3 Primary air admission No adjustment of the primary air by the user shall be possible. The primary air admission ports shall be arranged in such a manner that they cannot be accidentally obstructed. 5.7.4 Ignition device The burner or, if fitted, the pilot burner, shall be readily accessible at all times so that it can be safely ignited with a match, even if the appliance is equipped with an automatic ignition device.

13 In the case where a single knob operates a safety device controlling both the burner and the pilot burner, no marking shall be required if improper operation is impossible. In all other cases, the OFF position shall be indicated by a full disc or circle having a minimum diameter of 3 mm. If the controls are actuated by rotation, the OFF position shall be obtained by clockwise rotation when observing the control frontally. 5.8.2 Flame failure device Each appliance shall be fitted with a flame monitoring device complying with EN 125 which controls the supply or interruption thereof to the burner and pilot burner, where fitted. The device shall be designed to ensure that in the event of malfunction of any component essential to its operation, the gas supply to the burner is automatically shut off. The appliance shall not be fitted with any device for permanently overriding, without sustained manual operation, the operation of the flame monitoring device. During ignition, however, temporary supply of gas without the presence of a flame is permitted under the conditions specified in 7.3.3.9. The relative positions of the pilot burner, where fitted, the flame monitoring device and the burner shall be fixed. 5.8.3 Atmosphere sensing device If an atmosphere sensing device, or equivalent, intended to prevent the release of combustion products in a dangerous quantity is fitted on the appliance, it shall comply with 6.3.9. 5.8.4 Electrical equipment The electrical equipment of the appliance shall be so designed and constructed as to obviate hazards of an electrical origin.
