This European Standard applies to appliances having flue gas systems of type B and type C (according to CEN/TR 1749) and to appliances designed for outdoor installations. EN 12309 does not apply to air conditioners, it only applies to appliances having:
-   integral burners under the control of fully automatic burner control systems,
-   closed system refrigerant circuits in which the refrigerant does not come into direct contact with the water or air to be cooled or heated,
-   mechanical means to assist transportation of the combustion air and/or the flue gas.
The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see definitions in EN 12309 1:2014).
In the case of packaged units (consisting of several parts), this European Standard applies only to those designed and supplied as a complete package.
The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by EN 12309.
Installations used for heating and/or cooling of industrial processes are not within the scope of EN 12309.
All the symbols given in this text should be used regardless of the language used.
1.2   Scope of this Part 6 to EN 12309
This part of EN 12309 specifies the calculation methods of seasonal performances for gas-fired sorption appliances for heating and/or cooling with a net heat input not exceeding 70 kW. It deals in particular with the calculation methods of reference seasonal performances in cooling and heating mode for monovalent and bivalent appliances.
NOTE   This European Standard serves as an input for the calculation of the system energy efficiency in heating mode of specific heat pump systems in buildings, as stipulated in EN 15316-4-2.

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.

EN 16340 specifies the safety, construction and performance requirements for combustion product sensing devices intended to be used in combustion control systems, hereinafter referred to as CPSD. This European Standard applies to sensing devices for the measurement of combustion products from burners and appliances for domestic, commercial and industrial use burning: - gaseous fuels according to EN 437; or - liquid fuels having a viscosity at the burner inlet of 1,6 mm2/s (cSt) up to 6 mm2/s (cSt) at 20 °C, higher boiling petroleum based first raffinates (viscosity greater than 6 mm2/s), that require preheating for proper atomisation. This European Standard applies to all types of stationary sensing devices measuring flue gas components O2, CO, CO2, H2, CxHy, NOX, SO2 or for a combination of them (multiple gasses). This European Standard applies also to sensing devices for extractive systems. This European Standard does not cover sensor requirements for combustible gas, combustible gas mixture and oil quality.
