CEN/TC 295/WG 3 - Open fires and inserts, with and without doors

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 European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) instructions and marking together with associated test methods and test fuels for type testing residential slow heat release appliances fired by solid fuel.
This European Standard is applicable to hand fuelled intermittent burning slow heat release appliances having thermal storage capacity such that they can provide heat for a declared period of time after the fire has gone out. This European Standard also specifies a minimum time period from the appliance achieving the maximum differential surface temperature and falling to 50 % of that maximum value. These appliances provide heat into the space where they are installed.
These slow heat release appliances 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 appliances may burn either solid mineral fuels, peat briquettes, natural or manufactured wood logs or be multi-fuel in accordance with the appliance manufacturer’s instructions. Wood pellets which are hand fuelled may also be burned either on the existing appliance bottomgrate 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, appliances having fan assisted combustion air or appliances with boiler.

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.

This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emissions) 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/or convection into the space where they are installed.  Additionally if fitted with a boiler or other heat exchanger 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 multi-fuel in accordance with the appliance manufacturer’s instructions. Wood pellets which are specifically intended to be hand fuelled only may also 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 the NOx, OGC/total hydrocarbons and particulate matter emission test methods; however it does not contain any limit values for these emissions.
