This document is applicable to residential solid fuel burning appliances of which the nominal space heat output is more than 6 % of the combined nominal space heat output and nominal water heat output (total heat output). This document specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) of appliances fired by solid fuel (hereafter referred to as “appliance(s)”) and provides instructions for them. Furthermore, it also gives provisions for the evaluation of conformity, i.e. initial type testing (ITT) and factory production control (FPC) and marking of these appliances. This document specifies CO, NOx, OGC and particulate matter (PM) emission test methods. This document is as well applicable to appliances intended to carry the load of a chimney. Appliances receiving combustion air through ductwork from outside the external envelope, which is not air tight, are not considered roomsealed. This document is not applicable to appliances with boiler parts in contact with fire or flue gases other than when the boiler parts are manufactured from steel or cast iron. This document is not applicable to appliances with a boiler intended for water systems having: - water temperatures above 110 °C and/or an operating pressure of more than 300 kPa (3 bar); - direct contact with sanitary hot water. This document is not applicable to appliances to be operated with ventilating systems which are intended to operate with pressure below -15 Pa in the room of installation of the appliance in relation to the outside atmosphere.
