Proposal for a European Parliament and Council Directive amending Council Directive 78/548/EEC on the approximation of the laws of the Member States relating to heating systems for the passenger compartment of motor vehicles (98/C 326/04) (Text with EEA relevance) COM(1998) 526 final - 98/0277(COD)

(Submitted by the Commission on 28 September 1998)

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 100a thereof,

Having regard to the proposal from the Commission,

Having regard to the opinion of the Economic and Social Committee,

Acting in accordance with the procedure laid down in Article 189b of the Treaty,

Whereas Directive 78/548/EEC (1) is one of the separate directives of the EC type-approval procedure which has been established by Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers (2), as last amended by Commission Directive 98/14/EC (3); whereas, consequently, the provisions laid down in Directive 70/156/EEC relating to vehicle systems, components and separate technical units apply to Directive 78/548/EEC;

Whereas, in particular, under Article 3(4) and Article 4(3) of Directive 70/156/EEC each separate directive is to be accompanied by an information document incorporating the relevant items of Annex I to Directive 70/156/EEC and also a type-approval certificate based on Annex VI thereto in order that type-approval may be computerised;

Whereas, in the light of technical progress, combustion heaters, usually fuelled by diesel, petrol or liquefied petroleum gas, are now fitted to many types of vehicle in order to provide heat for the passenger compartment (e.g. of buses), the load area (e.g. of trucks and trailers) or the sleeping compartment (e.g. of trucks and motor caravans) so that heat can be provided efficiently and without the noise and gaseous emissions associated with running the propulsion engine when the vehicle is parked; whereas, for reasons of safety, it is necessary to extend the scope of Directive 78/548/EEC to include requirements for combustion heaters, and for their installation; whereas such requirements should be representative of the highest standards consistent with current technology;

Whereas it is necessary to provide for type-approval for combustion heaters as components and for vehicles in which a combustion heater is installed;

Whereas in this Directive account should be taken of the other provisions which exist or are in preparation with respect to the safety and installation of gas and liquid fuel combustion heaters, and in particular Council Directive 90/396/EEC (4), as amended by Directive 93/68/EEC (5), with regard to the safety of gas appliances, European Norm prEN 1949 (November 1995) on a specification for the installation of LPG systems for habitation purposes in leisure accommodation vehicles and other vehicles and European Norm prEN 722-1 (November 1995) on liquid fuel heating systems for caravans and mobile homes,

2.2.3. In the case of M2 and M3 vehicles, the heater must not be positioned in the passenger compartment. However an installation in an effectively sealed envelope which also complies with the conditions in 2.2.2 may be used.

2.2.4. The label referred to in 1.4, or a duplicate, must be positioned so that it can be easily read when the heater is installed in the vehicle.

2.2.5. Every reasonable precaution should be taken in positioning the heater to minimise the risk of injury and damage to personal property.

2.3. Fuel supply

2.3.1. The fuel filter must not be situated in the passenger compartment and must be provided with an effective cap to prevent fuel spillage.

2.3.2. In the case of liquid fuel heaters, where a supply separate to that of the vehicle is provided, the type of fuel and its filler point must be clearly labelled.

2.3.3. A notice, indicating that the heater must be shut down before refuelling, shall be affixed if possible to the fuelling point or a suitable instruction included in the manufacturer's operating manual.

2.4. Exhaust system

2.4.1. The exhaust outlet shall be located to prevent emissions from entering the vehicle through ventilators, heated air inlets or opening windows.

2.5. Combustion air inlet

2.5.1. The air for the combustion chamber of the heater must not be drawn from the passenger compartment of the vehicle.

2.5.2. The air inlet must be so positioned or guarded that blocking by rubbish or luggage is unlikely.

2.6. Heating air inlet

2.6.1. The heating air supply may be fresh or recirculated air and must be drawn from a clean area not likely to be contaminated by exhaust fumes emitted either by the propulsion engine, the combustion heater or any other vehicle source.

2.6.2. The inlet duct must be protected by mesh or other suitable means.

2.7. Heating air outlet

2.7.1. Any ducting used to route the hot air through the vehicle must be so positioned or protected that no injury or damage could be caused if it were to be touched.

2.7.2. The air outlet must be so positioned or guarded that blocking by rubbish or luggage is unlikely.`
