ÖNORM EN 14785

This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emissions), instructions and marking together with associated test methods and test fuels for type-testing residential space heaters fired by wood pellets, and mechanically fed up to 50 kW nominal heat output. These appliances may be freestanding or inset appliances and provide heat into the space where they are installed and may be operated with either natural draught or fan-assisted combustion air. Additionally, where fitted with a boiler, they also provide domestic hot water and/or central heating. These appliances burn wood pellets only, in accordance with the appliance manufacturers instructions. They operate with firedoors closed only. Non mechanically fed appliances burning solid mineral fuels, peat briquettes and natural or manufactured wood logs are not included in this European Standard, but are covered by EN 13229 and EN 13240. NOTE These appliances may have an integral fuel hopper or be combined with an external fuel hopper.
