37、EN 15502-1:2012 (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 hea
38、t 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 incl
39、ude in one design more than one function. It may include for example: a sanitary hot water function; a function to supply the combustion air from the outside of the building; a function to dispose the combustion products to the outside of the building. The boiler design may be supplied to the market
40、 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. Connection to a chimney and the means of combustion air
41、supply is particularly relevant. This European Standard was established to deal with aspects related to: a) safety; b) rational use of energy; c) fitness for purpose. This European Standard is a first part of a series of standards that will describe the special requirements for specific boiler types
42、. This European Standard contains the common requirements that are applicable for the majority of the specific boiler types. This European Standard is to be used in conjunction with the specific Part 2. Matters related to quality assurance systems, tests during production, and certificates of confor
43、mity of auxiliary devices are not dealt with in this series of European Standards.

44、 This European Standard specifies the common 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
45、 assisted atmospheric burners or fully premixed burners, and are hereafter referred to as “boilers”. This European Standard is to be used in conjunction with the specific Parts 2 (Part 2-1 and following ones). This European Standard applies to boilers of types B and C, according to CEN/TR 1749:2009:
46、 a) that use one or more combustible gases of the three gas families at the pressures stated in EN 437; b) where the temperature of the heat transfer fluid 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
47、give rise to condensation under certain circumstances; e) 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” f) which are intended to be installed inside a building or in a partially protected place; g) which are intended to produce hot water either by the instantaneous or storage principle, the whole being marketed as a single unit. This European Standard applies to boilers designed for sealed w
