DIN EN 15502-2-2:2014-10EN 15502-2-2:2014 (E) 6 Introduction A gas-fired heating boiler is an appliance using gaseous fuel designed
43、 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 instantan
44、eous heat exchanger or 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 gases to the water. The boiler may include in one design more than one function. It may include for example:
45、a) a sanitary hot water function; b) 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 t
46、o the technical instructions. Boilers may be designed to be connected to specific parts of a building. Especially connection to a chimney may be relevant. This European standard was established to deal with aspects related to: c) safety; d) rational use of energy; e) fitness for purpose. Matters rel
47、ated to quality assurance systems, tests during production, and certificates of conformity of auxiliary devices are not dealt with in this series of European Standards Relation between this standard and EN 15502-1: This European Standard will be used in conjunction with EN 15502-1:2012 and follows t
48、he 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
49、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 an addition. Clauses, subclauses and annexes which are additional to those in EN 15502-1:2012 are numbered starting from
