4 Constructional requirements
4.1 Heating capacity
The nominal heating capacity, expressed in kilowatts, shall be:
 selected by the manufacturer;
 verified during the tests;
 indicated on the rating plate.
The nominal heating capacity shall be rounded off to the nearest multiple of 500 W.
4.2 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 Clause 6 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.
The stove shall be made of non-combustible materials except that combustible materials shall be allowed for
the following:
 components of accessories e.g. burner covers, if the parts are fitted outside of the boiler;
 internal components of controls and safety equipment;
 operating handles;

oSIST prEN 1:2013

 electrical equipment.
Component parts of covers, operating, 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 manufacturer or in the component part standard.
NOTE Because the entire heat dissipating surfaces of the appliance including the flue spigot/socket and the flue gas
connector are working surfaces, there is no requirement for limiting the surface temperature of the appliance.
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 oil 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 Oil regulator
Oil regulators, or equivalent devices, shall maintain the flow of oil 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 oil regulator shall have clearly visible and permanent markings.
4.7 Safety device
The stove shall have a safety device to prevent overflowing of the oil 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 oil
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 the current is restored, the fuel shall be readmitted to the burner
manually. For automatically operated burners (automatic ignition), when the current is restored, the ignition
without a blow-out shall be ensured.
4.9 Fuel lines
The fuel lines shall not be load-bearing parts of the construction.
The fuel lines shall be resistant to the fuel and shall not exceed the maximum permissible surface
temperatures specified by the ma
