This document gives details for the classification of gas appliances according to the method of supplying combustion air and of evacuating the products of combustion (types). This classification refers to gas appliances that are intended to be installed within buildings and/or outside of the building . The European Standard classifies appliances as type A, B or C according to the basic principle for the evacuation of the products of combustion and air inlet. In references to a gas appliance/gas appliances connected via lits or their duct or ducts, it is intended that the air inlet duct and/or the discharge duct for carrying any products of combustion are part of the gas appliance. This means that such ducts are certified together with the gas appliance. In terms of this standard a "single duct" is a flue duct designed and capable to discharging the products of combustion and/or air inlet duct for the air supply for only one appliance. In terms of this standard a "common duct" is a flue duct designed and capable to discharging the products of combustion and/or air inlet duct for the air supply for more than one appliance. This European Standard is a guide for the harmonization of product standards, for the preparation of installation standards and for the common understanding of the types of gas appliances. This European Standard is neither an installation standard nor a product standard.

This document is applicable to gas-fired mCHP appliances producing domestic hot water and electricity. The electricity is generated in a process linked to the production of useful heat. It applies to a mCHP appliances marketed as single unit or as a package fully specified by a manufacturer that have: - a gas heat input not exceeding 400 kW, - an electrical output not exceeding 50 kW, and - a hot water storage capacity (if any) not exceeding 2 000 l. EN 13203 1:2015 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a variety of uses. It also gives a system for presenting the information to the user. The present document sets out a method for assessing the energy performance of gas fired mCHP appliances. It defines a number of daily tapping cycles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user. When the mCHP generator does not supply domestic hot water in the summer period, the present standard is not applicable. FprEN 13203 2:2018 is used for performance assessment of these generators.
