ÖNORM EN 624

This European standard specifies the characteristics of safety, construction, performance and efficiency, the test methods and marking, of room sealed space heating equipment of type C (see CR 1749) with combustion air intake and outlet for the products of combustion in the wall, roof or floor, combined or not. These are referred to in the body of the text as "heaters", burning LPG, for road vehicles and boats. The European standard only covers type testing of room sealed heaters also including those which have a combustion air fan, an integral hot air fan or both, only for road vehicles and boats which are used for residential, recreational and commercial purposes. For private cars and vehicles or boats used for the transport of dangerous goods or for commercial personnel transport additional requirements may be necessary. This European standard applies to heaters which are installed either outside or inside the habitable volume but which have a combustion circuit sealed from the vehicle s interior, a nominal heat input which does not exceed 15 kW (H ) operated at supply pressures of 30 mbar, 28 mbar, 37 mbar and s 50 mbar, using, where appropriate, 12 V or 24 V DC electrical supply. NOTE If a LPG operated heater is installed in a motorized vehicle being subject to European road traffic legislation, the directives of the Council for the approximation of the laws, regulations and administrative provisions of the member states relating to the heating of the interior of motor vehicles should be applied. These heaters are also suitable for mobile homes and mobile units.
