Gas-fired central heating boilers - Part 2-1: Specific standard for type C appliances and type B2, B3 and B5 appliances of a nominal heat input not exceeding 1 000 kW
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 1749:2009: 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; 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 provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard, the risk associated with this alternative construction needs to be assessed. An example of an assessment methodology, based upon risk assessment and which covers the essential requirements of the Gas Appliance Directive, is given in Clause 11. This European Standard does not cover all the requirements for: k) Appliances that are intended to be connected 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 DD); l) Appliances using flue dampers; m) Appliances of the types B21, B31, B51, C21, C41, C51, C61, C71 and C81; n) C7 appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW; o) Appliances incorporating flexible plastic flue liners; p) Appliances designed to become connected to a combined flue duct system that is designed to operate under overpressure (for example Ca)); q) Appliances incorporating a combined combustion products circuit that is designed to operate under overpressure (for example Cb)); r) Appliances intended to be connected to a (common) flue having mechanical extraction.

SIST EN 15502-2-1:2013
EN 15502-2-1:2012 (E) 6 Introduction A gas-fired heating boiler is an appliance using gas as fuel designed to heat water with the purpose of providing heat to a building (or portion of a building) from one point to multiple rooms using heat emitters such as radiators and convectors to transmit the heat from the water to the room. The boiler may also be used to provide domestic hot water via an indirect hot water storage tank. The basic function of gas-fired heating boiler is to generate heat by direct heat transfer in a heat exchanger, from the combustion gasses to the water. The boiler may include in one design more than one function. It may include for example: a) a sanitary hot water function; b) a function to supply the combustion air from the outside of the building; c) a function to dispose the combustion products to the outside of the building. The boiler design may be supplied to the market in more than one part. If the boiler is supplied to the market in multiple parts, the boiler is the assembly of various parts according to the installation instructions. Boilers may be designed to be connected to specific parts of a building. Especially, connection to a chimney and the means of combustion air supply are relevant. This European Standard was established to deal with aspects related to: d) safety; e) rational use of energy; f) fitness for purpose.
Matters related to quality assurance systems, tests during production, and certificates of conformity of auxiliary devices are not dealt with in this series of European Standards. Relationship between this document and EN 15502-1, Gas-fired heating boilers Part 1: General requirements and tests: This European Standard is to be used in conjunction with EN 15502-1:2012 and follows the numbering structure of EN 15502-1:2012. This European Standard refers to clauses of EN 15502-1:2012 or adapts clauses by stating in the corresponding clause: shall be according to EN 15502-1:2012, (clause number) with the following modification shall be according to EN 15502-1:2012, (clause number) with the following addition EN 15502-1:2012, (clause number) is replaced by the following; EN 15502-1:2012, (clause number) is not applicable. This European Standard adds clauses or subclauses to the structure of EN 15502-1:2012 which are particular to this standard. It should be noted that these clauses and subclauses are not indicated as SIST EN 15502-2-1:2013
EN 15502-2-1:2012 (E) 7 an addition. Clauses, subclauses and annexes which are additional to those in
EN 15502-1:2012 are numbered starting from 101, or designated as Annex AA, BB, CC, etc. Annex AA lists those existing standards which are replaced by this standard in combination with EN 15502-1. After the DOW (3 years after publication of both EN 15502-1 and EN 15502-2-1 in the OJEU) the standards specified in Annex AA, for the appliance types covered in EN 15502-2-1, are withdrawn. Annex AA lists those existing appliance types for which CEN/TC109 standards are intended to be replaced by EN 15502-2-2. The standards listed in Annex AA are to be used until EN 15502-2-2 specifies that the standards are withdrawn for the appliance types indicated.

EN 15502-2-1:2012 (E) 8 1 Scope 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 1749:2009: 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; 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 provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard, the risk associated with this alternative construction needs to be assessed. An example of an assessment methodology, based upon risk assessment and which covers the essential requirements of the Gas Appliance Directive, is given in Clause 11. This European Standard does not cover all the requirements for: k) Appliances that are intended to be connected 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 DD); l) Appliances using flue dampers;
m) Appliances of the types B21, B31, B51, C21, C41, C51, C61, C71 and C81; n) C7 appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW; o) Appliances incorporating flexible plastic flue liners; p) Appliances designed to become connected to a combined flue duct system that is designed to operate under overpressure (for example Ca)); SIST EN 15502-2-1:2013
