This European Standard is applicable to boilers used for central heating in accordance with EN 303-1:2017 up to a nominal heat output of 1000 kW and EN 303-4 up to a nominal heat output of 70 kW with forced draught burners in accordance with EN 267 that are designed for operating with liquid fuels. The performance requirements of this standard apply to type testing to heating boilers (standard, low temperature and condensing boilers) which are tested on a test rig in accordance with the test code given in EN 304. This standard applies also to room sealed boilers as defined in EN 15035 regarding efficiency and emissions. This standard can also be used as the basis for evaluation of boiler-/burner units.

This European Standard applies to boilers used for central heating (heating boilers) with forced draught burners with a nominal heat output not exceeding 1000 kW, which are operated either with negative pressure (natural draught boilers) or with positive pressure (pressurized boiler) in the combustion chamber, in accordance with the boiler manufacturers instruction. This standard specifies the necessary terminology, the requirements on the materials and testing of them, and marking requirements for heating boilers. Particular requirements for boilers that can be used with open vented systems are contained in EN 3034. The requirements of this standard apply to heating boilers that are tested on an authorized test rig. Boilers in accordance with this standard are designed for the heating of central heating installations in which the heat carrier is water, and the maximum allowable operating temperature of which is restricted to 100 °C. The maximum allowable operating pressure is 8 bar. For boilers (storage or continuous flow heater) this standard only applies to the parts of the water heater that are necessarily subject to the operating conditions of the heating boiler (heating part). This standard does not apply to gas boilers with atmospheric burners, boilers for solid fuels, boilers and boilers with oil vaporization burners. For these boilers there are further requirements.

This European Standard specifies, the requirements and test methods concerning, in particular, the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as "boilers". Where the word boiler is used, it needs to be read as the boiler including its connecting ducts, ducts and terminals, if any. This European Standard covers gas-fired central heating boilers from the types C1 up to C9 and the types B2, B3 and B5, according to the classification in CEN/TR 1749: a) that have a nominal heat input (on the basis of net calorific value) not exceeding 1000 kW; b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437; c) where the temperature of the heat transfer fluid does not exceed 105 °C during normal operation; d) where the maximum operating pressure in the water circuit does not exceed 6 bar; e) which may or may not give rise to condensation under certain circumstances; f) which are declared in the installation instructions to be either a "condensing" boiler or a "low temperature boiler" or a "standard boiler"; if no declaration is given the boiler is to be considered a "standard boiler"; g) which are intended to be installed either indoors or outdoors in a partially protected place; h) which may include the facility to produce hot water, either by the instantaneous or storage principle, the whole being marketed as a single unit; i) which are designed for either sealed water systems or for open water systems; j) which are either modular boilers, or non- modular boilers. This European Standard will be used in conjunction with the General Requirements Standard EN 15502-1. This European Standard provides requirements for boilers with known constructions. For boilers with any alternative constructions, which
