Gas-fired central heating boilers - Part 2-2: Specific standard for type B1 appliances of a nominal heat input not exceeding 70 kW
EN 15502-2-2:2014

EN 15502-2-2 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 and are hereafter referred to as “boilers”. Where the word boiler is used, this is to be read as the boiler including its connecting ducts, ducts and terminals, if any. This European Standard covers gas-fired central heating boilers type B11, B11BS, B12, B12BS, B13, B13BS 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 70 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 are declared in the technical instructions to be either a “low temperature boiler” or a “standard boiler”. If no declaration is given the boiler is to be considered a “standard boiler”; f) which are intended to be installed either indoors or in a partially protected place; g) which are either not intended to produce hot water, or are intended to produce hot water either by the instantaneous or storage principle, the whole being marketed as a single unit. h) which are designed for either sealed water systems or for open water systems. This European Standard is to be used in conjunction with the General Requirements Standard EN 15502-1. For applications within the scope of the PED further requirements may be necessary (e.g. situations where the maximum allowable temperature exceeds 110 °C, or where volume times maximum allowable pressure is over 50 bar x litres). This 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 shall 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 standard does not cover all the requirements for: i) 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 of EN 15502-2-1:2012); j) appliances using flue dampers; k) appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW; l) appliances of the types A, B14, B2, B3, B4, B5 and C; m) appliances intended to be connected to a (common) flue having mechanical extraction; n) appliances with gas/air ratio control; o) modular boilers; p) boilers which can give rise to condensation under certain circumstances; q) boilers intended to be installed in a room with a foreseeable negative pressure relative to the pressure in the flue system.

3   where the maximum operating pressure in the water circuit does not exceed 6 bar;
3   that can give rise to condensation under certain circumstances;
3   of the standard and low-temperature types.
This European Standard applies to boilers designed for sealed water systems or for open water systems.
This European Standard does not contain all the requirements necessary for boilers:
3   intended to be installed in the open or in living rooms;
3   permanently fitted with more than one flue outlet;
3   where the combustion circuit is sealed with respect to the room where the boiler is installed;

Replace the 2nd dash of the third paragraph by the following text :
"- condensing boilers;"
Delete the last but one paragraph of EN 303-3 :
"This European Standard does not contain all the necessary requirements for low temperature boilers. Nevertheless, the testing methods defined by this European Standard for the determination of useful efficiencies can be used for low temperature boilers, after being adapted in accordance with annex H."

Gas-fired central heating boilers - Type B boilers of nominal heat input exceeding 70 kW but not exceeding 300 kW
EN 656:1999

This 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".  This standard applies to boilers of type B, as listed in 4.2:   ? that use one or more combustible gases of the three gas families at the pressures stated in Tables 14 and 15;  ? that have a nominal heat input (net CV basis) exceeding 70 kW, but not exceeding 300 kW, including modular boilers;  ? where the temperature of the heat transfer fluid does not exceed 105 oC during normal operation;  ? where the maximum operating pressure in the water circuit does not exceed 6 bar.  The standard applies to boilers designed for sealed water systems or for open water systems.  The standard does not contain all the requirements necessary for boilers:   ? intended to be installed in the open or in living rooms;  ? permanently fitted with more than one flue outlet;  ? where the combustion circuit is sealed with respect to the room where the boiler is installed;  ? of the condensing type;  ? of the low temperature type;  ? intended to be connected to a common flue having mechanical extraction;  ? fitted with a forced draught burner in accordance with EN 676;  ? producing hot water for domestic purposes.  This standard only covers type testing.

Heating boilers - Part 3: Gas-fired central heating boilers - Assembly comprising a boiler body and a forced draught burner
EN 303-3:1998

This European Standard specifies the requirements and test methods for the construction, the safety and the rational energy usage of an assembly made up of a boiler body complying with EN 303- 11) and a forced draught gas burner complying with EN 676, using combustible gases, hereafter referred to as a "boiler".  This European Standard applies to a boiler:  - with a nominal output not exceeding 1 000 kW.  This European Standard does not contain all the necessary requirements for:  - assemblies designed as units;  - condensing boilers and low temperature boilers;  - boilers intended to be installed in the open;  - boilers permanently fitted with more than one flue outlet;  - boilers fitted with a draught diverter;  -  boilers intended to be connected to a common flue having mechanical    extraction.  This European Standard does not apply to living-space dedicated boilers   If the boiler body has already been tested with a liquid fuel burner, in accordance with EN 303-1, EN 303-2 and EN 304, only the tests described in annex G need to be performed.  In the case of a range of boilers, see annex F.  This European Standard does not contain all the necessary requirements for low temperature boilers. Nevertheless, the testing methods defined by this European Standard for the determination of useful efficiencies can be used for low temperature boilers, after being adapted in accordance with annex H.  This European Standard only covers type testing.
