Congratulations on your new SCAN DSA fire cassette. We are confident that you will enjoy your new cassette,
especially if you follow the instructions and advice given below.
An original SCAN DSA cassette is delivered with a sign with the following information: Type of cassette,
output, approvals, and registration number .
INSTRUCTIONS FOR INSTALLATION
In the SCAN DSA cassette you will find the following:
1 oven mitten
1 handle to operate the shaking grate (SCAN DSA 3)
Fitting for the flue collar
1 set of screws and hexagon spanners
Firelighters for the first lighting
Before the Cassette is Connected to the Chimney:
Contact your local authorities to obtain the existing fire- and building regulations regarding the installation, or
ask your local experts in that field, e.g., the chimney sweep, to install your cassette. All SCAN DSA cassettes are
closed fireplaces.
Mounting of the connecting piece:
The connecting piece is fastened underneath the top plate.
CONNECTION TO THE CHIMNEY
We recommend that the cassette is installed by a professional stove/fireplace dealer. The cassette should not be
connected to a chimney of which the inside diameter is smaller than 175 cm
2
(ø 150 mm).
Regarding chimney draught: please see Instruction for Use.
Please note that the cassette, chimney and pipe should be installed in a way that they can be cleaned easily.

First Time of Use:
The paint will harden the first time the cassette is used. This will result in a burned smell, which, however,
disappears again when the room is thoroughly aired.
LIGHTING AND STOKING
Primary air for the lightning:
The handle for the primary air (see sketch, no. 7) is underneath the door at the left side of the cassette. By pulling
out the handle the primary air is opened. The primary air should be fully opened in approximately 2 minutes
during lightning and stoking.
Lightning:
For lighting use pieces of crumbled paper (newspaper) and/or firelighters, and about two kgs wood (small pieces)
on top of the paper. Do never use oil, gas or other flammable liquids!
The combustion air (see sketch, no. 6) should be fully opened. Paper and/or firelighters are lighted and the door
remains slightly open. When the fire has caught on well, after about 10-15 minutes, the cassette is ready for the
first portion of wood, and the combustion air and primary air are adjusted according to the following diagrams.
Depending on the chimney draught the position of the air valves can change.
Air Valve Position:
Type of Cassette SCAN DSA 3 SCAN DSA 4
Combustion air, open 60% 60%
Primary air during lightning 100% 100%
Stoking:
Use the amount of fuel previously specified and ensure that the wood has the prescribed size. Do not pack the
wood too closely - this is important in order to obtain an optimal airflow in the combustion material. Close the
door after approx. 2 min. To avoid overheating, close the ash pan (SCAN DSA 3) as soon as the fire has caught
on well. The ash pan must only be opened during lightning and stoking.
Please make sure that the right amount of fuel is used (according to the previous table). Otherwise the
temperature in the chimney can be too high and the efficiency too low and a damage of the chimney can occur.
Stoking During Spring Time and Autumn:
At outdoor temperatures of more than 15°C, the cassette may be under fired, and a so-called "cold" combustion
will build-up. The result will be an increasing formation of soot in the smoke ducts of the cassette, the chimney
connector, and in the chimney. To avoid the soot build-up, we recommend that you clean the smoke ducts more
frequently and increase the supply of combustion air. Small pieces of wood should be used, and fuel should be
added more frequently.
Chimney Draught:
The chimney draught depends on the weather conditions. In stormy weather, you may reduce the chimney
draught by closing the damper in the smoke pipe (if a damper has been installed). If the chimney draught is
strong, the combustion air supply must be reduced additionally.
Room Ventilation:
During the combustion, oxygen taken from the room air is used. In order to get sufficient air for the combustion,
leave the windows half open in well-insulated rooms or have a fresh-air intake installed.
Cleaning:
Be careful when you empty the cassette for ashes. There may be glows left as long as 24 hours after the cassette
was last used. The ash may, when it is cold, be placed in a garbage bag.

COMBUSTION CHARACTERISTICS OF DIFFERENT WOOD TYPES:
Type of Tree Combustion value per m3
(in kWh) Combustion value per kg
(in kWh) Notes
Beech 2.100 4.0 long, continuous fire
Oak 2.100 4.2 long , continuous fire
Birch 1.900 4.3 nice flame image
Pine and Douglas Larch 1.700 4.4 fast, crackling heat
Spruce 1.500 4.5 fast, crackling heat
Storage of the Wood:
The correct storage of the wood is one of the main conditions of an environment-conscious combustion. Only
hereby are you guaranteed optimal combustion values, and that the nature is not unnecessarily polluted.
* The wood should be stored in an airy, sunny, and dry place (ideal: South side)
* There should be about a hand's breadth distance between each layer
* Poplar and spruce should be stored at least one year before being used as fuel
* Lime, alder, and birch should be stored at least one and a half year before being used as fuel
* Beech, ash, and fruit tree should be stored at least two years before being used as fuel
Soot Free Glasses:
The cassette is constructed to keep the glasses clean when the combustion air intake is fully opened. The more
you close the combustion air, the greater is the risk for sooty glasses. Whenever a new portion of wood is placed
in the cassette, it is necessary to open the combustion air completely, and the air intake must not be reduced until
there are clear flames all around the wood. Max. humidity of the wood: 20%.
Fire Bricks:
Little cracks may arise in the firebricks because of a minor content of water, especially if the cassette is
overheated during the first firing. These cracks do not influence the efficiency of the cassette and are not covered
by the guarantee.
If a spare part is needed, please state the number of the firebrick (no 1-4). The number shows also the way of
mounting the firebricks.
MAINTENANCE INSTRUCTIONS
The cassette is cleaned with a moist cloth. Spray lacquer is available for repair of possible damages/scratches.
Your dealer has the right spray in the right colour. As there may be minor colour differences, it is recommended
to repair larger areas with natural borders. You will get the best result if the cassette is repaired while it is warm
(remember a good airing during the repair). A possible change of colour to grey is caused by over-firing, i.e. you
have used more wood than recommended.
Cleaning of Glass:
By burning wet wood or lighting with closed dampers, the doors may become sooty. The glasses are however
easily cleaned by use of a special cleaning fluid, which is available at your dealer. Or as follows: Dip a moist
cloth or an old newspaper in the ashes and use this to clean the glass. Attention! The ashes should not get into
contact with your skin! Wipe with a dry cloth. The ceramic door joint must not get wet.
Ceramic Packing Cord:
All SCAN DSA cassettes are equipped with ceramic packing cord to ensure the tightness of the doors and the
glasses. This packing cord is a wearing part and must be changed from time to time. Please consult your
authorized dealer in this case.

MOUNTING/DISMOUNTING OF DOORS
In general, we recommend that you leave the dismounting of the door to the authorized dealer.
1. Close the door.
2. Loosen the screws
3. Remove the door.
Mounting is made in reverse order.
REPLACEMENT OF GLASS:
Dismount the door and place it on a plane surface with its back upwards. Remove all the screws of the inner
frame. Remove the inner door and replace the glass. Change the ceramic packing cord if necessary. Remount the
inner frame and remount the door on the cassette. Please note that the glass must not be firmly fixed.
MOUNTING OF THE CERAMIC SMOKE DEFLECTOR
A ceramic smoke deflector is delivered with all SCAN DSA cassettes. Place the smoke deflector plate according
to sketch 5; make sure that it is placed symmetrically in the cassette, i.e., with even amounts of free airspace on
each side.
By cleaning the chimney and pipe soot can fall down on the plate. Remove the soot by tipping the plate. The soot
will fall into the combustion chamber.
Note: Skamol is a porous material, and can break easily. The plate is a wearing part, and can/must be replaced
after some time. (The Skamol plate is not covered by the guarantee).
TROUBLE SHOOTING
