M/577 - Space heating appliances REV

This European Standard covers multi-firing sauna stoves in which the heating stones are separated from and indirectly heated by the fire and the flue gases and which may be re-fuelled with several fuel loads.
This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) of multi-firing sauna stoves fired by wood logs and provides instructions for them. Furthermore, it also gives provisions for evaluation of conformity (i.e. initial type testing (ITT) and factory production control (FPC) and marking of these products.
This standard is applicable to hand-fuelled intermittent burning multi-firing sauna stoves, which provide heat into the space where they are installed.
These multi-firing sauna stoves may be supplied either as an assembled appliance or as a manufacturer’s pre-designed unit consisting of pre-fabricated components designed to be built on site in accordance with the manufacturer’s specified assembly instructions. One-off installations are not included.
These multi-firing sauna stoves may burn only natural wood logs in accordance with the appliance operating instructions.
Single-firing heat storage sauna stoves, in which the stones are directly heated by the fire and the flue gases, which pass through them, are not covered by this European Standard. This standard is also not applicable to mechanically fed sauna stoves, sauna stoves having fan assisted combustion air, sauna stoves fitted with a boiler, sauna stoves with incorporated flue or sauna stoves having any electrical connection.

This document is applicable to space heaters, inset appliances and cookers intended for mechanical fuelling with wood pellets and for manual fuelling with wood logs. They can be freestanding or inset appliances.

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 16510-2-2:2022.
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.
