In the case of waste heat heating systems using the cooling air of the engine for heating purposes, the conditions of paragraph 6.2 of this Regulation are considered satisfied without the use of a heat exchanger provided that the following conditions are satisfied: 6.1. the cooling air which is used for heating purposes comes into contact only with surfaces of the engine which do not include any detachable part, and 6.2. the connections between the walls of this cooling air circuit and the surfaces used for the transfer of heat are gastight and oil-resistant. These conditions are considered satisfied if, for example: — a sheath around each sparking plug draws off any gas leaks outside the heating air circuit; — the joint between the cylinder head and the exhaust manifold is situated outside the heating air circuit; — there is double leak protection between the cylinder head and the cylinder and any leaks from the first joint are drawn off outside the heating air circuit, or the leak protection between the cylinder head and the cylinder still holds when the cylinder head nuts are cold-tightened at one-third of the nominal torque prescribed by the manufacturer, or — the area where the cylinder head is joined to the cylinder is situated outside the heating air circuit.

ANNEX 4 TEST PROCEDURE FOR AIR QUALITY 1. In the case of vehicle type-approval the following test shall be carried out: 1.1. Operate the heater for one hour at maximum output in conditions of still air (wind speed ≤ 2 m/s), with all windows closed and, in the case of a combustion heater, the propulsion engine switched off. 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: 1.2.1. a point outside the vehicle as close as possible to the heating air inlet, and 1.2.2. 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 described in paragraph 1.2.2 shall be less than 20 ppm CO higher than from position described in paragraph 1.2.1. 2. In the case of type-approval of heaters as components the following test shall be carried out after the tests of Annexes 5, 6 and paragraph 1.3 of Annex 7. 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 less than or equal to 30 dm3/h.

ANNEX 5 TEST PROCEDURE FOR TEMPERATURE 1. 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 15 °C. 2.

In the case of exposed parts of the heating system outside the passenger compartment, and in the case of overheating, the temperature shall not exceed 110 °C. The temperature of the heated air entering the passenger compartment shall not exceed 150 °C to be measured at the centre of the outlet.

ANNEX 6 TEST PROCEDURE FOR EXHAUST EMISSION OF COMBUSTION HEATERS 1. Operate heater for one hour at maximum output in conditions of still air (wind speed ≤ 2 m/s) and an ambient temperature of 20 ± 10 °C. 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. 2. The dry and undiluted exhaust emissions, measured using an appropriate meter, shall not exceed the values indicated in the following table: Parameter Heaters using gaseous fuels Heaters using liquid fuel CO 0,1 % vol. 0,1 % vol. NOx 200 ppm 200 ppm HC 100 ppm 100 ppm Bacharach reference unit (1) 1 4 3. The test shall be repeated in conditions equivalent to a vehicle speed of 100 km/h (or maximum design speed of the vehicle in cases where the maximum speed is less than 100 km/h). Under these conditions the CO value must not exceed 0,2 % vol. If the test has been carried out on the heater as a component, then it need not be repeated in the case of the vehicle type in which the heater is installed.

If an LPG heating system in a motor vehicle can also be used when the vehicle is in motion, the LPG combustion heater and its supply system shall comply with the following requirements: 1.1.1. The LPG combustion heater shall comply with the requirements of the harmonized standard EN 624:2000 (Specifications for dedicated LPG appliances. Room sealed LPG space heating equipment for installation in vehicles and boats). 1.1.2. In cases of a permanently installed LPG container all components of the system that are in contact with LPG in the liquid phase (all components from the filling unit to the vaporiser/pressure regulator) and the associated liquid phase installation shall comply with the technical requirements of Regulation No 67, Parts I and II and Annexes 3 to 10, 13 and 15 to 17. 1.1.3. The gaseous phase installation of the LPG heating system in a vehicle shall comply with the requirements of the harmonized standard EN 1949:2002. (1) (Specifications for the installation of LPG systems for habitation purposes in leisure accommodation vehicles and in other road vehicles). 1.1.4. The LPG supply system shall be so designed that the LPG is supplied with the required pressure and in the correct phase for the installed LPG combustion heater. It is permitted to withdraw LPG from the permanently installed LPG container in either gaseous or liquid phase. 1.1.5. The liquid outlet of the permanently installed LPG container to supply LPG to the heater shall be provided with a remotely controlled service valve with excess flow valve as required in paragraph 17.6.1.1 of Regulation No 67. The remotely controlled service valve with excess flow valve shall be controlled such that it is automatically closed within five seconds of the vehicle engine stopping, irrespective of the position of the ignition switch. If within these five seconds the on-switch of the heater or LPG supply system is activated, the heating system may stay in operation. The heating can always be restarted. 1.1.6. If the LPG is supplied in the gaseous phase from the permanently installed LPG container or separate portable LPG cylinder(s), appropriate provisions shall be taken to ensure that: 1.1.6.1. no liquid LPG can enter the pressure regulator or LPG combustion heater. A separator may be used, and 1.1.6.2. no uncontrolled release due to an accidental disconnection can occur. Means shall be provided to stop the flow of LPG by installing a device directly after or in a cylinder or container mounted regulator or if the regulator is mounted remote from the cylinder or container, a device shall be installed directly before the hose or pipe from the cylinder or container and an additional device shall be installed in, or after the regulator. 1.1.7. If the LPG is supplied in liquid phase, the vaporiser and pressure-regulator unit shall be heated as appropriate by a suitable heat source. 1.1.8. In motor vehicles that use LPG in their propulsion system, the LPG combustion heater may be connected to the same permanently installed LPG container that supplies LPG to the engine, provided that the safety requirements of the propulsion system are met. 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 TRAILERS 2.1. 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 paragraph 1.1.1 above. 2.1.3. The gaseous phase installation of the LPG heating system shall comply with the requirements of paragraph 1.1.3 above. (1) Prepared by the European Committee for Standardisation (CEN).
