46、14EN 15502-2-2:2014 (E) 6 Introduction A gas-fired heating boiler is an appliance using gaseous 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 th
47、e heat from the water to the room. The boiler may also be used to provide domestic hot water via an instantaneous 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
48、gases 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 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 th
49、e boiler is supplied to the Market in multiple parts, the boiler is the assembly of various parts according to 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 related to quality assurance systems, tests during production, and certificates of conformity of auxiliary devices are not dealt with in this series of European Stan
