CE CERTIFICATE AND SAFETY TEST
NATURE OF THE TEST
All DAN SKAN stoves including the new MODERN LINE range have CE conformance certificates having successfully passed all the requirements of the European test EN13240.
The test results are significantly lower in all areas than the European limit values as well as the certification programme DIN Plus and the Stage II of the strict German BImSchV. Other tests included the Austrian norm 15aB-VG with the demands of the FGV from the Steirmark, the norm concerning safety measurements for small burning sections (BMfWA), the demand of the BStV of the cities Munich and Regensburg and others as well as the Swiss norm of the Association of Cantonal Fire Insurance Companies.
- Particulate Matter
The fine particle emissions in the flue gases at nominal heat output (EN kW) are below 29 mg/Nm³ at 13 % O2
- Carbon Monoxide
The concentrations in the exhaust at nominal heat output are below Vol 0.10 % at 13 % O2
The efficiencies are well above the limit values specified in standards being >80 %
TEST CONDITIONS AND RESULTS
The test conditions and results are based on a standard sized chimney with a delivery pressure of 12 Pascal (Pa). The combustion air was regulated in the same way as a stove owner would by using the intelligent automatic bimetal system and the wood logs used had a residual moisture content of less than 15 %.
For DAN SKAN owners this means that the highest performance can easily be achieved outside the test laboratory!
TOP FIRE WITH WOOD
For the best results place your wood logs across each other in the fire chamber and ignite from the top of the stack = TOP FIRE! Gas and debris escape mainly from the cut ends of the logs so keep these away from the glass surface.
A quick starting fire is very important in eliminating smoke and emissions and starting the flue draught cycle. DAN SKAN stoves are started with the riddle grate closed and the pull control open. The starting fire is prepared by placing several logs side to side on top of each other and then placing a layer of kindling on top of these.
DAN SKAN stoves start with air (secondary and tertiary) delivered over the top of fire for clean and efficient combustion. After the first refuelling with logs (between 1 and 2 hours) the fire chamber and the flue system will now be hot enough to provide the correct negative pressure in the chimney stack for effective operation.
SAFETY AND CARE
Be sure to keep an eye on the stove during the start-up phase especially if you leave the stove door ajar to provide extra initial combustion air. We recommend good proprietary fire lighters to start the fire – never use methylated spirit, petrol or other inflammable liquids. Never leave matches on or near the stove. Do not leave it too late to refuel your stove. Always add wood to the fire when there are still enough small flames in the chamber to help ignite them quickly.
If you refill when there are only dying embers this will significantly slow the up-draught and the wood will also be slow to ignite. Remember it is flames that produce an effective up-draught and also ensure unproblematic opening of the stove door to minimise fly-ash and smoke entering the room. Opening the stove door very slowly also helps avoid these problems.
With the DAN SKAN automatic system closing the air supply as the fire burns down you may be left with some charcoal embers – this is a clear sign of a very economical and effective air supply. The charcoal embers will then provide a very good ‘foundation’ for the next firing.
AIR SUPPLY TO THE ROOM
There are strict legal requirements for maintaining a sufficient supply of air to the room to ensure the health and safety of the room‘s occupants. These will be laid out in local, national and European building regulations and should be adhered to at all costs.
As stoves will take some or all of their combustion air from the room they are located in and the stove owner must ensure that there is a safe uninterrupted supply of air for both the stove and anyone using the room. With modern day energy saving measures and well sealed floors, doors and windows some rooms can be virtually air-tight. To offset this and to conform with regulations a dedicated non-closable air vent or external air supply direct to the stove may need installing and you should consult your approved stove installer to advise you. Based on the nominal heat outputs of DAN SKAN stoves, we suggest the following guidelines regarding combustion air requirements:
< 4 kW burning = < 12 m³/hour
< 6 kW burning = < 15 m³/hour
< 8 kW burning = < 18 m³/hour
DAN SKAN stoves can be operated with an external or direct air supply to provide 100 % of the stove‘s combustion air requirements so that when burning they do not deplete the air in the room the stove is installed in.
The conventional EX-AIR-1 system with its connection from the external air and the air in the room enables a pressure balance in the room the stove is installed in. The EX-AIR-2 system enables pre-heated combustion air because of the DAN SKAN patented AIRBOX. With heat recovery systems (0kW houses or low-energy houses) the pressure in the room where the stove is to be installed should not be higher than 4 Pascal.
Most of the MODERN LINE stoves have passed a strict new test at the respected RFF-Test Institute in Germany for approval by the important German Institute for Construction (Deutsches Institut Fuer Bauchtechnik).
This tests the ‘stove burning independently with external air’ and examines the CO-concentration (ppm) in the smoke and the leak rates (m³/h) with 10 Pa and after the stove has been subjected to thermal and mechanical stress. For example the stove’s door seal must pass certain ‘air tightness’ requirement after the door has been opened and closed a minimum of 6,000 times.
Permitted fuels include wood logs with a residual moisture content of no more than 18 % which should be cut into appropriate lengths between approximately 250 and 330mm, depending on the fire chamber size. The wood should be air-dryed. Approved smokeless fuels and brown coal briquettes are also permitted.
The combustion of household waste, especially plastic, is not permissible as it could damage the stove or flue components and invalidate your warranties.
The burning of combustible materials releases energy which leads to intense heating of the external surfaces of the stove including the door handle. Care must be taken to avoid touching the stove without proper protection (for example heat resistant gloves or other protective aids). Never leave children unattended in the room where your stove is being operated. Ensure that children are aware of the potential danger and make sure that they keep clear of the stove when it is in operation. Where children, the elderly or the infirm are present always use an approved safety fireguard to prevent accidental contact with the stove. An approved carbon monoxide detector should be fitted in the same room as the stove. It should be powered by a battery designed for the working life of the alarm. Please note this is now a requirement under UK Building Regulations.
