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 document is applicable to slow heat release appliances for solid fuel (freestanding manually fuelled intermittent burning slow heat release appliances (SHRA) having heat storage capacity such that they can provide heat and release it for an extended period after the fire has gone out).
The intended use of the appliances is space heating in residential buildings. They can be fitted with a boiler or heat exchanger (integral part of the appliance containing water to be heated up) for the supply of hot water for central heating systems.
These slow heat release appliances may be supplied either as an assembled appliance or as a pre-designed unit consisting of prefabricated components designed to be built on site in accordance with the-specified assembly instructions.
These appliances can burn one or more types of the following solid fuels as specified:
—   wood logs;
—   compressed untreated wood;
—   wood pellets;
—   lignite briquettes;
—   solid mineral fuels;
—   peat briquettes.
This document is not applicable to:
—   mechanically fed appliances
—   appliances with fan assisted combustion air
—   one off installations
This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of solid fuel burning slow heat release appliances.

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. 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 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.
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 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.
