This document is applicable to space heaters, inset appliances and cookers intended for mechanical fuelling with wood pellets and for manual fuelling with other solid fuel. They can be freestanding or inset appliances. The intended use of the appliances is space heating in residential buildings and can be cooking. They can be fitted with a boiler (integral part of the appliance containing water to be heated up) for the supply of hot water for central heating systems. These appliances typically use auxiliary energy which is measured in this standard as well. They are operated with natural draught and can be fan-assisted. NOTE 1 A fan-assisted appliance does still operate under negative pressure in the flue gas system. For inset appliances and especially their testing additional information can be necessary from EN 16510-2-2. These appliances burn wood pellets and wood logs only, in accordance with the appliance instructions. They only operate with the firedoors closed. NOTE 2 These appliances can have an integral fuel hopper or be combined with an external fuel hopper. These appliances can be fitted with a single or double combustion chamber having a single flue gas outlet. This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of combination appliances fired by wood logs and pellets. This document is not applicable to appliances – with boiler intended for water systems having water temperatures above 110°C and 3 bar and for sanitary hot water, – intended to be used with a pure horizontal exhaust (through the building wall), – with flue gas condensation in the appliance, – switching on / off for part load operation, – with simultaneous wood and pellet operation with a single flue gas outlet, – with non-automatic pellet loading, – with single combustion chamber and double flue gas outlet.
