5.6 Fuel requirements

Wood quality
Chopping and storing wood
You can use any type of wood as fi rewood. However, harder
types such as beech and ash are generally better as they
burn more evenly and create less ash. Other wood types, like
maple, birch and spruce, also make excellent fi rewood.
Firewood is best if you fell the tree and saw and split the wood
before May 1st.
Remember to cut the logs to the size of your stove's combustion
chamber. We recommend a diameter of 6 to 10 cm and the
length should be about 10 - 20 mm shorter than the combustion
chamber, to leave enough space for air to circulate. Logs with
a larger diameter than this will need splitting before use. Split
wood dries faster.
Sawn and split logs should be stored in a dry place for 1 to 2
years before they are suffi ciently dry to use.
It's a good idea to bring logs in to stand at room temperature
for a few days before using them.
Moisture
To avoid environmental problems and to ensure optimum
burning effi ciency, the wood must be completely dry before it
is used as fi rewood:
• The moisture content should not be more than 20%.
• A moisture content of between 15% and 18% yields best
results. An easy way to check if wood is dry is to knock two
logs together. If the wood is damp, the logs will sound dull
when knocked together.
• If the wood used is too damp, most of the heat it produces
will be used to evaporate the water. The stove does not
heat up and does not heat the room. This is not economical.
It also causes soot to build up on the glass, in the burn
chamber and in the chimney. Burning damp wood also
causes pollution.
Be especially careful never to use the following
materials as fuel in your fi replace:
• Household rubbish, plastic bags, etc.
• Painted or impregnated timber (which is extremely toxic).
• Laminated wooden planks.
• Driftwood
These may harm the product and are also pollutants.
NB: Never use petrol, paraffi n, methylated spirit or similar
liquids to light the fi re. You may cause serious injury to yourself
and damage to the product.
5.7 Wood consumption
Wood consumption, at nominal heat output: Approx. 2,8 kg/h.
The size of the logs should be:
Kindling (fi nely split wood):
Length: 20 - 30 cm
Diameter: 6 - 10 cm
Quantity for kindling: 3 logs weighing 0.6-0.8 kg each and 10
to 12 sticks weighing about 1 kg in total.
Stoking the fi re:
Wood (split wood):
Length: 20 - 30 cm
Quantity required each time: 2 or 3 logs weighing 0.7 kg each,
i.e. 1.5-2.0 kg each time.
Stoking frequency: Approx. 45 minutes
Nominal heat output is achieved when the air vent is open
approximately 67,5 % and the ignition vent is open 25%.
When testing in accordance with the EN 13229 standard, the
amount used is 3 pieces of 1,5 - 2,0 kg.
Vent setting: 25 % opening of the ignition vent and 67,5 %
opening of the air vent.

6.0 Maintenance

6.1 Cleaning the glass

The product is equipped with an air wash for the glass. Air is
sucked in through the air vent on the top of the product and
down along the inside of the glass.
Good advice! For normal cleaning, moisten a paper towel or
a sponge with warm water. Rub it over the glass to remove
the soot and clean with clean water. For diffi cult stains use a
glass cleaner (follow the instructions on the bottle). Be careful
not to get water on the gaskets, paint or enamel. This could
cause damage.

6.2 Ash removal

Only remove ash when the fi replace is cold.
Use a scoop or similar to remove the ash through the door.
Always leave some ash as a protective layer on the bottom of
the fi replace.

6.3 Cleaning and soot removal

Soot deposits may build up on the internal surfaces of the
fi replace during use. Soot is a good insulator and will therefore
reduce the fi replace's heat output. If soot deposits accumulate
when using the product, they can easily be removed by using
a soot remover.
An annual internal cleaning is necessary to get the best
heating effect from your product. It is a good idea to do this
when cleaning the chimney and fl ue pipes.
