M/577 AMD 1 - Space heating appliances_Amd1

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.
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 16510-2-2:2022.
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.
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,
-   continuous burning appliances.
For clarity, all test methods are addressed in Annex A.

This document is applicable to oil stoves. These appliances have one or more vaporizing burners and a nominal heating capacity of not more than 15 kW and are equipped either with a draught regulator or a combustion air limiter.
The intended use of the appliances is space heating in residential buildings.
This document is also applicable to appliances with fan assisted vaporizing burners.
According to the type of fuels used in the country of destination, the appliances are supplied for use with either:
-   fuel oil with a maximum kinematic viscosity of 6,0 mm²/s at 20 °C;
-   or kerosene with a flash point of not less than 40 °C.
This document is not applicable for:
-   built-in appliances;
-   appliances equipped with an atomizing burner;
-   appliances incorporating a boiler or connected to a water system.
This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of flued oil stoves with vaporizing burners.

This European
Standard is applicable to residential freestanding hand fuelled intermittent burning slow
heat release appliances having thermal storage capacity such that they can provide
heat for an extended period of time after the fire has gone out. Maximum firing time is 3
hours. These slow heat release appliances may be supplied either as an assembled
appliance or as a manufacturer’s predesigned
unit consisting of
prefabricated components designed to be built on site in accordance with the
manufacturer’s specified assembly instructions. One off installations are not included
as they are not covered by the scope of this standard. This European standard is also
applicable to appliances which are designed for operating under room
sealed conditions and which are intended to be installed into a chimney not serving any
other appliances. These appliances can contain also fluid heating device which can be
either a boiler or a heat exchanger that is not in contact with flames or flue gases. Note:
Appliances which receive their combustion air from outside by means of a pipe system
which is not air tight are not considered room sealed in accordance with this
standard. This European Standard specifies requirements relating to the design,
manufacture, construction, safety and performance (efficiency and emission) together
with associated test methods and test fuels for residential slow heat release appliances
fired by solid fuel (hereafter referred to as “appliances”), 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
appliances. These appliances provide heat by radiation and convection from the
surface and can also have channels for improved convection. They provide heat into
the space where they are installed. Additionally if fitted with a boiler or a heat
exchanger that is not in contact with flames or flue gases, these appliances may also
provide domestic hot water and/or central heating. These appliances may burn either
solid mineral fuels, peat briquettes, natural or manufactured wood logs or be multifuel
fired in accordance with the appliance manufacturer’s instructions. Wood pellets which are specifically intended to be hand fuelled can be burned either on the existing
appliance bottom grate or in a special basket arrangement which is placed by the user
into the existing firebox. This European Standard is not applicable to mechanically fed
appliances. This European standard is also not applicable to appliances which are
designed to be operated with ventilating systems which have pressure below (– 15 Pa)
in relation to the outside atmosphere as measured in the room where the appliance
is installed. This European Standard covers also CO, NOx, OGC (total hydrocarbons)
and particulate matter emission test methods; however it does not contain any values
for the limit on these emissions. This part 25
of a European Standard series is
applicable to slow heat release appliances. This part 25
is to be used in conjunction
with the latest edition of EN 165101
and its amendments. It is established on the basis
of EN 165101:
2015. When this standard states “addition”, “modification”
or “replacement”, the relevant text in part 1 is to be adapted accordingly.
