— wood logs;
— compressed untreated wood;
— wood pellets;
— lignite briquettes;
— solid mineral fuels;
— peat briquettes.
This document is also applicable to Kachelofen/Putzofen inset appliances, having nominal heat outputs

1 Scope
This document is applicable to hand fed solid fuel fired inset appliances, with or without functional
modification, that operate without firedoors or operate with fire doors either as closed only or as closed
or open, and also includes open fires fired by solid fuel. The surround of these appliances are integrated
with the building with the exception of free-standing appliances and those inset appliances which are
installed into a fireplace recess or enclosure. These appliances provide heat into the space where they
are installed. Additionally, where fitted with a boiler, they also provide domestic hot water and/or central
heating.
These appliances can burn one or more types of the following solid fuels in accordance with the appliance
manufacturer’s instructions:
— wood logs;
— compressed untreated wood;
— wood pellets;
— lignite briquettes;
— solid mineral fuels;
— peat briquettes.
This document also covers ‘Kachelofen’ and ‘Putzofen’ inset appliances, having nominal heat outputs up
to 15 kW.
This document is not applicable to appliances with fan assisted combustion air or appliances that are
mechanically fed.
Open fireplace components such as a bottomgrate with associated firefront which the manufacturer
supplies for installation into an existing heat resistant, insulated firebox are not covered by this
document.
This document is used in conjunction with prEN 16510-1:2021 of which it is an integral part.
