Gas-fired central heating boilers - Type B boilers, fitted with atmospheric burners of nominal heat input not exceeding 70 kW (consolidated version)
This document specifies the requirements and test methods for the construction, safety, fitness for purpose, rational use of energy, classification and marking of gas-fired central heating boilers, hereafter referred to as "boilers".
This document applies to type B11, B11BS, B12, B12BS, B13, B13BS, B14, B22, B23, B32, B33, B44, B52 and B53 boilers
as listed in 4.2.21) :
that use gases corresponding to the three gas families and to the pressures stated in 7.1.4;
that have a nominal heat input not exceeding 70 kW (on net calorific value);
where the temperature of the water does not exceed 95 °C during normal operation;
where the maximum water-side operating pressure does not exceed 6 bar;
fitted with atmospheric burners, atmospheric burners assisted by a fan for the supply of combustion air or the evacuation of combustion products or premixed burners;
and that may be fitted with electrically operated mechanical flue dampers that are positioned downstream of the heat exchanger and tested as an integral part of the boiler.
This document does not contain all the necessary requirements for:
boilers:
intended to be installed in the open;
having multiple heating units with a single draught-diverter;
of the condensing type;
intended to be connected to a common flue having mechanical extraction;
fitted with manual means of adjusting the air supply and/or adjusting the evacuation of the combustion products;
of the combination type (central heating and domestic hot water production);
without a draught-diverter and not incorporating a fan;
specifically of the types B21, B31, B41, B42, B43 and B51;
nor for appliances:
combining the functions of an independent space heater and a hot water generator for central heating.
This document only covers appliances where the fan, if any, is an integral part of the appliance.
This document only covers appliances where the flue damper, if any, is an integral part of the appliance.
1) National installation regulations may limit the modes of installation permitted in the territory of a CEN member state.

Diese Europäische Norm legt die Anforderungen und Prüfungen für den Bau, die Sicherheit, die Gebrauchsgüte und den sparsamen Energieeinsatz, die Klasseneinteilung und die Kennzeichnung von Heizkesseln fest, die mit gasförmigen Brennstoffen betrieben werden (nachfolgend kurz "Kessel" genannt). Diese Norm gilt nur für Kessel, bei denen das eventuell vorhandene Gebläse ein fester Bestandteil des Kessels ist. Diese Norm gilt nur für Kessel, bei denen ein eventuell vorhandener Zugbegrenzer ein fester Bestandteil des Kessels ist. Diese Norm gilt nur für die Baumusterprüfung. Diese ÖNORM enthält die Europäische Berichtigung AC:2006 mit der Tabelle 19 und 20 geändert wurden. Die Änderungen A2 bis A6 wurden bereits 2005-07 aufgenommen.
