EN TESTING
CE CERTIFICATE AND SAFETY TESTS
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.
PRIORITY RESULTS
1. Particulate Matter
The fine particle emissions in the flue gases at nominal heat output
(En kW) are below 29 mg/Nm³ at 13 % O 2
2. Carbon Monoxide
The concentrations in the exhaust at nominal heat output are below
Vol 0.10 % at 13 % O 2
3. Efficiency
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.
as a guideline the combustion air needed for a Dan SKan
stove is:
< 4 kW burning = < 12 m³/hour
< 6 kW burning = < 15 m³/hour
< 8 kW burning = < 18 m³/hour
EX-AIR OPERATION
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.
DIBt TESTING
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
Permitted fuels include wood logs with a residual moisture content
of no more than 18 % which should be cut into lengths between
approximately 250 to 330 mm. 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.
SAFETY INSTRUCTIONS
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.
