Gas-fired heating boilers - Part 1: General requirements and tests
This document specifies the common requirements and test methods, as well as the classification,
marking and energy labelling 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 to be used in conjunction with the specific Parts 2 (Part 2-1, Part 2-2 and following
ones).
This document applies to boilers of types B and C:
NOTE For further background information on appliance types see EN 1749:2020.
a) that use one or more combustible gases of the three gas families at the pressures stated in EN
437:2021;
b) where the temperature of the water does not exceed 105 °C during normal operation;
c) where the maximum operating pressure in the water circuit does not exceed 6 bar;
d) which can give rise to condensation under certain circumstances;
e) which are declared in the instructions for installation to be either a "condensing" boiler or a "low
temperature boiler" or a "standard boiler" or an "other boiler". If no declaration is given the boiler is
to be considered both a "standard boiler" and an "other boiler";f) which are intended to be installed inside a building or in a partially protected place;
g) which are intended to produce also hot water either by the instantaneous or storage principle as a
single unit.
This document applies to boilers designed for sealed water systems or for open water systems.
NOTE This general standard and the specific standards (see Part 2) provide requirements for boilers with known
constructions. For boilers with any alternative constructions, which might not fully be covered by this standard or a specific
standard, the risk associated with this alternative construction will need to be assessed.
An example of an assessment methodology, based upon risk assessment, is given in Clause 11.
This document is not intended to cover appliances intended for connection to gas grids where the quality
of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex AB).
This document does not cover all the requirements for :
aa) appliances above 1000 kW;
ab) appliances designed and constructed to burn gas containing carbon monoxide or other toxic
components;
