4.1 General
The fireplace shall be produced in such a way as to:
— rule out any type of permanent deformations or other damages on the fireplace after testing;
— withstand any tensions occurring during normal use;
— facilitate being operated safely.
The use of decorative elements, e.g. imitation wood, pebbles in the area of flame impingement are not
permitted.
4.2 Fuel volume
The maximum burner volume shall not exceed 3 litres. The total fuel capacity of the fireplace shall not
exceed 10 litres
NOTE National or regional legislation might impose lower limits.
4.3 Design
The fireplace shall be fitted with a feature with an easy-to-use closing mechanism (in order to extinguish
the flames). This mechanism shall work reliably and safely whilst the fireplace is in use. If required by
means of auxiliary tools, these shall be provided with the fireplace.
Furthermore, the design of the construction shall ensure:
— any welding seams of the fuel storage tank shall be continuously welded;
— that replaceable parts or parts necessary for assembly on site shall not be fitted incorrectly;
— that all parts used for operation and/or maintenance of the fireplace shall be free from sharp edges
which could constitute a safety hazard for the user;
— an extinguishing device fulfilling 5.3.5.
4.4 Fuel storage container
4.4.1 General
The way of safe refilling of the fireplace shall be specified in the instruction for use and maintenance.
If symbols on the burner are not coloured, coloured stickers shown in Figure 1 shall be added to the
burner, in order to force the removing before the first use of the fireplace.
The fuel storage container shall be leak proof. This is checked by the test under 5.2.1.
The fireplace shall be constructed in such a way that any fuel leakage is avoided. In order to prevent
leakage, an additional containment chamber shall be provided which has a minimum volume of 110 % of
the actual filling volume and that prevents the accumulation of explosive gases. This is checked by the
test under 5.2.2.
NOTE This can be achieved for example by sufficient ventilation.
An additional containment chamber that does not allow the checking and removal of any excess fuel is
prohibited.
The product documentation shall contain safety advice regarding the danger of ignition of fuel overspill.
Furthermore, the user shall be instructed to check and remove any excess fuel in the secondary
containment chamber before lighting the fireplace.
The fireplace shall be equipped with a durable and clearly visible device which helps preventing
overfilling and subsequent overrun of fuel during filling when carried out in accordance with the intended
terms of use. A level indicator or a fill level mark are regarded as suitable devices.
4.4.2 Container marking
Clearly visible and durable warning sign shall be shown around the filling opening of the fireplace
indicating that filling when warm or in operation is not allowed (Figure 1). This shall be according to
ISO/TS 20559:2020, 6.6.2.
Figure 1 — Graphical symbols “Do not fill fuel into the open flame. Do not fill fuel into the hot
burner” (ISO 7010 - W021)
The height of the symbol shall be at least 25 mm. If the symbol is engraved or laser etched into the metal,
it does not have to be coloured. Marking of components of the fireplace which are removed during
operation or a marking of accessories (funnel, lighter, fuel refill container) are not considered as
sufficient.
The durability of the marking shall be checked according to 5.2.4.
4.5 Materials
The parts which are in contact with the fuel shall be constructed with chrome-nickel steel X5CrNi18-10
according to EN 10088-3:2023.
NOTE 1 This is equivalent to chrome-nickel steel 1.4301.
If different materials are used, their suitability in terms of thermal, chemical, mechanical properties and
corrosion resistance shall be proven by specification or by test; special consideration shall be given to
materials used in areas touching the flame.
Soldering flux containing Asbestos and Cadmium shall not be used in any components of the fireplace.
Any insulation material shall be non-combustible (A2s1d0 class according to EN 13501-1:2018) and its
application shall not pose any threat to health and safety.
Filling materials used in the burners shall be durable and specifically suited for the thermal strain under
contact with fuel and its combustion and shall not alter their properties. Proof shall be presented in order
to make sure the suitability of the material. This shall be tested according to 5.2.3.
NOTE 2 Certificates issued by a test institute are acceptable proof.
The burner, and all components which can reach a temperature over 65 K above room temperature, shall
be constructed of non-combustible materials.
4.6 Stability
If fittings for the mounting or fixing of the fireplaces are provided with the fireplace, they shall be durable
for the whole life of the fireplace.
If unintentionally moved or tilted during operation the fireplace shall be stable according to the tests in
5.1.
Fireplaces provided with wheels, or any other device helping their movement, shall be naturally blocked
and it shall be impossible to move them without extinguishing the flame.
The freestanding fireplaces shall pass the stability test (tilting and sliding, impact, movement test), as
stated in 5.1.
For all the tests the fuel tank shall be filled with fuel to the maximum level according to the user
instruction.
For wall-mounted fireplaces, unintentional movement or release shall be prevented. Especially it shall
not be possible to unintentionally unlatch or lift off the fireplace from its fittings. This should be checked
during the test in 5.1.5.
Damage to the fireplace which is caused by impact stress (e.g. crack in a glass screen) are acceptable as
long as the requirements towards mechanical stability and fuel spillage are met.
4.7 Ignition device
The fireplace shall be safe to ignite.
It shall be possible to light the fireplace with commonly available lighters, if the fireplace is not equipped
with an integrated ignition device, a suitable lighter shall either be provided with the fireplace or the
instruction for use shall give information on suitable lighters. The user shall be able to ignite the fire from
a horizontal minimum distance of 140 mm (shortest distance between the handle of the lighter or ignition
device and the burner opening).
Devices which would enable the user to light the fire without visual contact with the flames are not
allowed.
If a remote-control device is provided, an accidental ignition shall not be possible, and a child safety
device shall be provided.
EXAMPLE Pressing two buttons is considered enough for chid safety.
4.8 Operation of the fireplace
4.8.1 Fuel consumption and thermal output
The fireplace shall be constructed in such a way that over the whole burning period, there shall be no
increase of fuel consumption, that can cause a burner runaway. The verified thermal output shall
be ≤ 4,5 kW. This shall be checked by the test described in 5.3.2.
4.8.2 Flame accessibility
The access to the fire shall be obstructed at least from one side. If areas of the fireplace could be used as
a repository, the access to the fire shall be blocked from two sides. The housing of tabletop fireplaces shall
restrict access to the flames from at least two sides. The majority of flames in fireplaces which are open
at the top shall be shielded by the screens.
Where glass screens are used, their construction and attachment to the fireplace shall be such that they
are made of either glass-ceramic, borosilicate or tempered glass, but in any case, that the screen:
— is of at least 4 mm thickness;
— is able to withstand maximum temperatures of the fireplace (of a minimum temperature of at least
250 °C). This requirement is considered to be fulfilled by using the mentioned materials;
— has appropriate thermal expansion properties that enable it to expand and contract without cracking
during use, this requirement is considered to be fulfilled, if after the tests performed in Clause 5 there
is no visible damage;
— has appropriate thermal shock ratings such as it can tolerate sudden temperature changes without
cracking;
— has no sharp edges along any of its surfaces.
4.8.3 Draught protection
The fireplace shall be constructed in such a way to prevent flaring out of the flames under normal air
draft conditions by more than the safety distance as indicated in the instructions and shall not exceed in
any case 50 cm.

5.2.2 Test on overfilling
The burner shall be overfilled with 10 % of the container capacity but with a maximum of 100 ml and lit.
The test is considered as passed if extra flames are safe and do not lead to explosions.
NOTE The capacity given in the instructions is not considered.
5.2.3 Filling material
The change of the weight and the dimensions of the dry filling material shall not exceed 5 % after the
following test. A representative piece of filling material shall be kept at operating temperature (or 60 °C)
for 42 d. The weight and the dimensions of the dry filling material shall be determined before and after
the test.
Furthermore, a visual check shall be done to ascertain whether there are flaws in the structure of the
filling material (local damage).
After the storage test, the ignition tests according to 5.3.7.6 shall be performed and passed.
5.2.4 Container marking test
The durability of the safety mark/symbol is not only to be tested and confirmed during operation in
accordance with the intended terms of use, but shall additionally be confirmed in the following test
procedure: For the duration of 15 s the symbol shall be firstly rubbed with a cotton cloth soaked in water.
Subsequently, it shall be again rubbed for 15 s with a cotton cloth soaked in fuel.
If symbols on the burner are not coloured, coloured stickers shown in Figure 1 shall be added to the
burner. These stickers may be removed before the first use of the fireplace. Stickers alone are not
acceptable.
The test shall show whether the mark/symbol remains clearly legible following the specified treatment.
The method of safe refilling of the fireplace shall be specified in the user instruction.
5.3 Operating tests
5.3.1 Test conditions
All tests shall be carried out with one of the fuels specified in the list of recommended fuels given in the
instructions for use and maintenance. Uncertainty of measurement shall be in accordance with Table 3.
Testing room:
— temperature 20°C ± 5°C;
— relative humidity between 30 % and 90 %.

5.3.2 Fuel consumption
Over the whole burning period, there shall be no increase of fuel consumption, that can cause a burner
runaway.
The verified thermal output shall be ≤ 4,5 kW.
The whole fireplace shall be placed on a scale, and fuel consumption determined at the maximum setting.
Since the construction of the fireplace can greatly influence the fuel consumption it is not allowed to
perform these measurements on the burner alone.
The test period shall begin with the ignition and shall last at least until 30 min after the fireplace has
reached thermal stability or at least until a full fuel tank has been consumed. The reading of weight change
shall be made every 5 min. Thermal stability is considered as reached when three consecutive readings
do not deviate more than 5 % from each other.
It is not acceptable over the whole burning period, that there is an increasingly larger increase of fuel
consumption from reading to reading.
The fuel consumption B (kg/h) shall be determined from the weight change readings.
The thermal output is calculated as follows:
P BH⋅ (1)
i
where
P thermal output, kW;
B fuel consumption, kg/h;
=
H calorific value of the fuel, kWh/kg.
i
The given calorific value of the used fuel is used in the calculation.
NOTE For fuel with ethanol concentration of at least 95 %, H = 7,4 kWh/kg can be used.

5.3.3 Operating safety
5.3.3.1 Draught protection
The fireplace shall be constructed in such a way to prevent flaring out of the flames under normal air
draft conditions by more than the safety distance as indicated in the instructions and shall not exceed in
any case 50 cm. The following test is failed, if the given safety dista
