4.1 Heat output
The nominal heat output, expressed in kilowatts, shall be:
— specified;
— verified during the tests;
— indicated on the rating plate.
The nominal heat output shall be rounded off to the nearest multiple of 500 W.
4.2 Construction and materials
The quality of the materials as well as the shape and dimensions of the components shall ensure that,
provided the operational procedures are met and with the associated mechanical, chemical and thermal
stresses which occur, the stoves will remain safe and operable over a given period.
The stove shall be fire-resistant and safe to operate, and shall be designed such that:
— no visible deformations following the performance tests according to A.5 occur;
— it can withstand the stresses arising during normal operation;
— the burner and the stove cannot become heated to create a hazard;
— dangerous accumulations of combustible gases (fuel mixed with air) in the combustion chamber and
in the flues are prevented (for automatically operated burners only);
— gases cannot leak from the stove in dangerous quantities.
Non-combustible materials (materials according to the annex of Commission Decision (96/603/EU) or
A1 materials according to EN 13501-1:2018) shall be used, except that it shall be permissible to use
combustible materials for the following applications:
— components of accessories e.g. burner covers, if the parts are fitted outside of the burner;
— internal components of controls and safety equipment;

— operating handles;
— electrical equipment.
Components for covering, operation, control and safety devices and electrical accessories shall be
arranged in such a way that their surface temperatures, under steady state conditions, do not exceed
those specified either by the component manufacturer or in the component part standard.
NOTE Since the entire heat dissipating surfaces of the appliance including the flue spigot/socket and the flue
gas connector are working surfaces there are no limits for their surface temperature.
4.3 Combustion chamber
The combustion chamber shall be properly sealed and fitted with a device (e.g. lid, door, etc.) which
cannot be locked, and designed to compensate for any excess pressure.
4.4 Filter
The stove shall include at least one filter situated either before or inside the fuel regulator and a strainer
in the filling orifice. The filter shall retain particles with a diameter of over 0,25 mm. The filter and
strainer shall be easy to remove and clean.
4.5 Fuel regulator
Fuel regulators, or equivalent devices, shall maintain the flow of fuel reaching the burner at a constant
value corresponding to the setting selected.
The closed and maximum open positions shall each have a limiting stop.
The minimum position shall be clearly marked and be sensed as a resistance that can be overcome
mechanically.
4.6 Marking of operating settings
The control device for the fuel regulator shall have clearly visible and permanent markings.
4.7 Safety device
The stove shall have a safety device to prevent overflowing of the fuel from the burner.
4.8 Fan for the supply of combustion air
Irrespective of the operating setting of the stove, the supply of combustion air from the fan shall not
create excess pressure in the combustion chamber. The operation of the fan shall be trouble free.
The function of the burner shall be linked with that of the fan. In the event of a failure of the fan, the flow
of fuel to the burner shall be either totally interrupted or reduced to a flow such that the smoke number
does not exceed the maximum permissible value for the operation of the burner without the fan.
If the fuel supply to the burner is completely cut off by an electric current failure, then for manually
operated burners (without automatic ignition), when th
