This document specifies the requirements and test methods, 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".
This document is intended to be used in conjunction with EN 15502-1:2021.
This document covers gas-fired central heating boilers from the types C1 up to C(11) and the types B2, B3 and B5:
NOTE 1 For further background information on appliance types see EN 1749:2020.
a) that have a nominal heat input (on the basis of net calorific value) not exceeding 1 000 kW;
b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437:2021;
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 can give rise to condensation under certain circumstances;
f) which are declared in the instructions for installation 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 inside a building or in a partially protected place;
h) which are intended to produce also hot water either by the instantaneous or storage principle 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.
k) which are from the types C(10) that are equipped with a gas-air ratio control and that have a ?pmax, saf(min) of 25 Pa, and C(11) that have condensing boiler modules that are equipped with a gas-air ratio control and that have a ?pmax, saf(min) of 25 Pa.
NOTE 2 This document provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully ...
