4 Requirements
4.1 General
The fireplaces shall be manufactured so that they:
— withstand loads occurring in operation;
— ensure safe use.
Electrically powered fireplaces shall meet the requirements of EN 60335-1 and EN 60335-2-102.
4.2 Design
4.2.1 Extinguishing system
The fireplace shall be equipped with a system that shuts down the fireplace.
The extinguishing system shall:
— ensure that the flame on the burner is effectively extinguished within the time specified in the
instruction for use but no longer than 2 min from the moment the stop command is issued
— provide visual and/or audible signals to inform the user of the start of the flame extinguishing
process
— prevent interruption the extinguishing sequence by any other action, e.g. re-starting, refueling; if
this could lead to danger.
4.2.2 The safety circuit
The safety circuit shall provide hazard detection for:
1. the temperature of critical components (e.g. fuel tank, burner);
2. fuel system leakage;
3. spillage of fuel during tank refilling;
4. attempts to access elements not intended for user operation (e.g. fuel filler);
Depending on the construction of the fireplace the safety circuit can optionally provide hazard detection
for:
5. concentration of combustion by-products, e.g. carbon dioxide;
6. motion detection, e.g. impact, movement, seismic shock;
7. other relevant hazards.
Any abnormal situation shall lead to a safety shut down, regardless of the operating status of the device
(e.g. standby mode, heating mode, cooling mode). The user shall be informed either by a visual or acoustic
signal. After a safety shut down it shall only be possible to re-lit the fireplace by user intervention.
The safety shut down shall extinguish the fire in 10 s or less.
4.2.3 Flame supervision device (FSD)
The fireplace shall have a flame supervision device. The FSD shall control the presence of fire in the
furnace during the combustion process. In case that the flame vanishes, the fireplace shall switch off
within 1 min and gives a signal that it is shutting down and an error occurred.
4.2.4 Ignition device
Ignition shall be carried out automatically using an ignition device built into the appliance.
If the appliance is fitted with a remote control system, the following requirements shall be met: The
remote control shall be designed and/or programmed to minimize the risk of its signals operating
another appliance.
The appliance signal receiver shall be designed and/or programmed to minimize the risk of the appliance
being operated by the remote controls for other appliances.
The remote control shall be so designed that operation of the appliance by means of this control is only
possible when the appliance is directly visible to an operator of the control who is present in the same
room as the appliance.
The remote control shall be so designed that:
— at least two distinct manual actions are required to start the operation of the fireplace (e.g.
activation of two different buttons) and
— the fireplace can be shut off quickly by means of a single action if necessary.
The user manual shall provide information for the safe use of the remote control.
4.2.5 Fuel tank
The fuel tank shall be constructed to prevent any leakage. This is checked according to 5.5.1.
The appliance shall be designed to ensure safety even in the event of fuel spillage (e.g. during filling or
refilling). The fireplace shall be equipped with a protection device that prevents ignition when fuel has
been spilled. At least one spill detector shall be installed where spilled fuel is likely to accumulate. If there
is a fuel system leak or the customer spills fuel, the safety circuit should trigger a shutdown. This is
checked according to 5.3, 5.4, and 5.5.2
NOTE Protection using electronic spill detectors is acceptable
Fireplace instructions for use shall include information on automatic stopping of the fireplace in case of
spillage, leakage or fuel tank overfill.
A safe fuel tank filling method shall be described in the instruction for use and maintenance.
Provisions shall be taken that the fuel tank cannot be refilled when the fireplace is in operation.
As part of the safety circuit, the fuel tank shall be fitted with a sensor monitoring its temperature in
operation and in standby. The safety circuit shall initiate a safety shut down if the fuel tank temperature
exceeds 60°C. This is checked according to 5.5.3
4.2.6 Mechanical construction
The appliance's structural design shall ensure that welds are tight and continuous for all parts that come
into contact with liquid fuel.
All parts accessible to the user under standard operating conditions of the appliance shall be designed in
such a way that any cuts or injury are prevented, e.g. due sharp edges.
4.2.7 Materials
The parts which are in contact with the fuel shall be constructed with chrome-nickel steel X5CrNi18-10
according to EN 10088-3.
NOTE This is equivalent to chrome-nickel steel 1.4301.
If different materials are used, their suitability for intended operation 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 5.7.
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.
4.3 Fireplace structure
For freestanding appliances as well as built-in appliances with opening from at least two opposing sides
(with respect to the longer dimension of the fireplace), access to fire shall be secured from both sides if
the distance from a setting edge to the appliance is less than 100 mm.
EXAMPLE A glass shield with 150 mm height from combustion chamber surface is a sufficient safeguard.
A service gap between glass
