Council Decision of 26 June 2001.,Whereas:(1)Council Directive 78/548/EEC of 12 June 1978 on the approximation of the laws of the Member States relating to heating systems for the passenger compartment of motor vehiclesOJ L 168, 26.6.1978, p. 40. was adopted as 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 trailersOJ L 42, 23.2.1970, p. 1. Directive as last amended by Directive 98/91/EC of the European Parliament and of the Council (OJ L 11, 16.1.1999, p. 25).. 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.(2)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.(3)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. For reasons of safety, it is necessary to extend the scope to include requirements for combustion heaters, and for their installation. Such requirements should correspond to the highest standards consistent with current technology.(4)It is necessary to provide for type-approval for combustion heaters as components and for vehicles in which a combustion heater is installed.(5)It will be necessary to supplement this Directive with additional safety requirements for liquefied petroleum gas (LPG) combustion heaters by the addition of an Annex.(6)The measures necessary for the implementation of this Directive should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the CommissionOJ L 184, 17.7.1999, p. 23..(7)For reasons of clarity it is advisable to repeal Directive 78/548/EEC and replace it by this Directive,HAVE ADOPTED THIS DIRECTIVE:

If, however, having selected the maximum output the heater switches off automatically in less than an hour, the measurements may be made before switch-off.1.2.The proportion of CO in the ambient air shall be measured by taking samples from:(a)a point outside the vehicle as close as possible to the heating air inlet, and(b)a point inside the vehicle less than 1 m from the heated air outlet.1.3.Readings shall be taken for a representative time of 10 minutes.1.4.The reading from position (b) shall be less than 20 ppm CO higher than from position (a).2.In the case of combustion heaters as components the following test shall be carried out after the tests of Annexes V, VI and item 1.3 of Annex VII.2.1.The primary circuit of the heat exchanger shall be subjected to a leakage test to ensure that polluted air cannot enter the heated air intended for the passenger compartment.2.2.This requirement shall be considered to be fulfilled if, at a gauge pressure of 0,5 hPa, the leakage rate from the heat exchanger is ≤ 30 dm3/h.ANNEX VTEST PROCEDURE FOR TEMPERATURE1.Operate the heater for one hour at maximum output in conditions of still air (wind speed ≤ 2 m/s), with all windows closed. If, however, having selected the maximum output the heater switches off automatically in less than an hour, the measurements may be made earlier. If the heated air is drawn from outside the vehicle the test shall be carried out at an ambient temperature of not less than 15o C.2.The surface temperature of any part of the heating system likely to come into contact with the driver of the vehicle during normal road use shall be measured with a contact thermometer.

If a separate LPG container is used for heating, this container shall be provided with its own filling unit.2.LPG HEATING SYSTEMS FOR STATIONARY USE ONLY IN MOTOR VEHICLES AND THEIR TRAILERS2.1.The LPG-combustion heater and its supply system of an LPG heating system that is intended to be used only when the vehicle is not in motion, shall comply with the following requirements:2.1.1.Permanent labels shall be attached on the compartment where the portable LPG cylinders are stored and in close proximity to the control device for the heating system, giving instructions that the LPG heater shall not be in operation and that the valve of the portable LPG cylinder shall be closed when the vehicle is in motion.2.1.2.The LPG combustion heater shall comply with the requirements of section 1.1.1.2.1.3.The gaseous phase installation of the LPG heating system shall comply with the requirements of section 1.1.3.ANNEX IXADDITIONAL PROVISIONS APPLICABLE TO CERTAIN VEHICLES AS DEFINED IN DIRECTIVE 94/55/ECOJ L 319, 21.12.1994 p. 71.SCOPEThis annex applies to vehicles to which specific requirements concerning combustion heaters and their installation laid down in Directive 94/55/EC apply.2.DEFINITIONSFor the purpose of this Annex, the definitions of the vehicle designations EX/II, EX/III, AT, FL and OX set out in Chapter 9.1 of Annex B to Directive 94/55/EC apply.3.TECHNICAL PROVISIONS3.1.General (EX/II, EX/III, AT, FL and OX vehicles)3.1.1.The combustion heaters and their exhaust gas routing shall be designed, located, protected or covered so as to prevent any unacceptable risk of heating or ignition of the load. This requirement shall be considered as fulfilled if the fuel tank and the exhaust system of the appliance conform to the provisions set out in the points 3.1.1.1 and 3.1.1.2. Compliance with those provisions shall be verified on the completed vehicle.3.1.1.1.Any fuel tanks for supplying the appliance shall meet the following requirements:(a)in the event of any leakage, the fuel shall drain to the ground without coming into contact with hot parts of the vehicle or the load;(b)fuel tanks containing petrol shall be equipped with an effective flame trap at the filler opening or with a closure enabling the opening to be kept hermetically sealed.3.1.1.2.The exhaust system as well as the exhaust pipes shall be so directed or protected to avoid any danger to the load through heating or ignition. Parts of the exhaust system situated directly below the fuel tank (diesel) shall have a clearance of at least 100 mm or be protected by a thermal shield.3.1.2.The combustion heater shall be switched on manually. Programming devices shall be prohibited.3.2.EX/II and EX/III vehiclesCombustion heaters using gaseous fuels are not permitted.3.3.FL vehicles3.3.1.The combustion heaters shall be put out of operation by at least the following methods:(a)intentional manual switching off from the driver’s cab;(b)stopping of the vehicle engine; in this case the heating device may be restarted manually by the driver;(c)start-up of a feed pump on the motor vehicle for the dangerous goods carried.3.3.2.After running is permitted after the combustion heaters have been put out of operation. For the methods set out in points (b) and (c) of paragraph 3.3.1 the supply of combustion air shall be interrupted by suitable measures after an after-running cycle of not more than 40 seconds. Only heaters for which proof has been furnished that the heat exchanger is resistant to the reduced after-running cycle of 40 seconds for the time of their normal use shall be used.
