Maintenance - SCAN 4-2 Instructions For Use Manual

Storing
You need to store the sawn and split firewood in a dry place for 1-2
years before burning. Wood dries faster if you stack it in an airy place.
Before use, store the firewood for a few days at room temperature.
Note that wood absorbs moisture during the autumn and winter
seasons.
Moisture
To avoid environmental issues, and for optimum burning, wood
has to be perfectly dry to be suitable for use as firewood. The max.
residual moisture in the wood should not exceed 21%. A moisture
content of 15-18% yields best results. As an easy way of checking
if wood is dry, just knock two pieces of wood together. If the wood is
moist, the sound will be dull.
If you use damp wood, most of the heat it produces will be used
to evaporate the water. The temperature in the wood stove does
not rise, and the room is not sufficiently heated. Of course, this is
not economical, and it will cause soot build up on the glass pane,
in the stove, and in the chimney. Burning moist wood also causes
pollution.
Understanding units for measuring wood
Various units of measurement are used for wood. Before you buy
wood, it makes sense to familiarise yourself with the terms. There are
various brochures, in public libraries for example, that cover this topic.
Use of the following as fuel is illegal
Painted, pressure impregnated, or glued wood, driftwood from the
sea. Never burn chipboard, plastics, or chemically treated paper.
These materials are dangerous to humans, to the environment, your
wood stove, and your chimney. To keep a long story short – make
sure you burn only quality firewood.
Firewood fuel value
The fuel value is different for different types of wood. In other words,
you need to use more wood of certain types to achieve the same
heating performance. This Instruction Manual assumes that you will
be using beech, which has a very high fuel value, and is also a wood
that is easy to procure. If you use oak or beech wood fuel, note that
these wood types have a greater fuel value than, say, birch. Make
sure you use less fuel to avoid damage to the wood-burning stove.

Maintaining your wood-burning stove
Apart from regular chimney sweeping, your wood stove does not
require any regular maintenance.
Coated surfaces
Clean your wood-burning stove by dusting with a dry, lint-free cloth.
If the topcoat is damaged, you can purchase a repair spray from your
authorised Scan dealer. As slight differences in colour are possible,
spray a larger area to achieve a natural transition for best results. For
best results, apply repair spray when the wood stove is hand-hot.
Cleaning the glass
Our wood-burning stoves are designed to prevent serious soot build
up on the glass. The best way to achieve this is to make sure you
have a sufficient secondary air supply. It is also important to use dry
wood, and have a correctly dimensioned chimney.
Even if you follow all of our instructions, a slight film of soot can build
up on the glass. You can easily remove this build up by cleaning with
a dry cloth and glass cleaner. Your authorised Scan dealer stocks a
special glass cleaner for this purpose.
Combustion chamber lining
Slight cracks can appear in the combustion chamber lining due
to moisture, or to the heating/cooling process. These cracks have
no influence on the heating performance or lifetime of your stove.
However, if the lining starts to crumble, you must replace it. The
combustion chamber lining is not covered by the warranty.
Seals
All wood-burning stoves have seals made of ceramic material fitted to
the stove, the doors, and/or the glass. These seals are subject to wear
and tear, and must be replaced when necessary.
Chimney sweeping and cleaning your wood-bur-
ning stove
Follow national and local chimney sweeping regulations. We
recommend having the wood-burning stove cleaned regularly by the
chimney sweep.
Before starting to clean your wood-burning stove, and sweep the flue
pipe, we recommend first removing the smoke deflector platens.
Use only original replacement parts for maintenance and
repairs of your wood-burning stove.
Note! Make sure the stove is cold before starting maintenance
or repair work.
Removing the smoke deflector plates
Lift the lower smoke deflector platen, remove the pins at the sides,
and then remove the platen. Remove the upper smoke deflector
platen in the same way.
