Warning against overheating
The fi replace must never be overheated
The fi replace has been developed and tested for use at a
nominal power of 14 kW. This corresponds to a combustion
of about 4.3 kg at per hour. Maximum at pr. load is about 6
kg (3-4 cubes at a time).
Important!
• Never fi re with a fully open ignition valve over time. A sure
sign of overheating is that the product gets glowing points.
Then reduce the air valve settings immediately!
• If there is a suspicion of excessive / poor draft in the
chimney, professional help must be sought for repair.
Odor during fi ring
During the fi rst heating, the fi replace can emit an annoying
gas that can smell something. This is because the paint
dries. The gas is not toxic, but the room should be properly
ventilated. Fire with good draft until all gases have burned out
- until neither smoke nor smell is felt anymore.
5.5 Requirements for fuel
Wood Quality
Storage
• All types of wood can be used as fuel. In general, the
hard woods are best to fi re with, e.g. beech or ash, which
burns evenly and gives little ash. Other types of wood
such as maple, birch and spruce are also excellent
alternatives.
• The best wood is obtained when the tree is felled, sawn
and split before 1 May.
• The length of the wood should be adapted to the
combustion chamber. It is recommended to make logs
with a diameter of 6–10 cm and 10-20 mm shorter than
the combustion chamber, so that there is room for air
circulation. If the logs are larger in diameter, the wood
should be split before use. Cleaved by dries fastest.
• The cut and split wood should be stored dry for 1 to 2
years before it is suffi ciently dry.
• It is a good idea to store the wood at room temperature
for a few days before using it.
Moisture
To avoid environmental problems and to get the best
possible fuel economy, the wood must be dry before it is
used as fuel:
• The wood can contain a maximum of 20% moisture.
• The best effi ciency is achieved at a humidity of 15–18%.
An easy way to control the moisture of the wood is to beat
the logs against each other. If the wood is damp, a blunt
sound is heard.
• A large part of the heat is used to evaporate the water if
the wood used is too moist. The wood stove therefore
does not rise in temperature and therefore does not emit
heat to the room. This is uneconomical, in addition to soot
settling on the glass, in the combustion chamber and in
the chimney. In addition, the environment is polluted by
burning with moist wood.

Be especially careful never to fi re with the
following materials:
• Household waste, plastic bags, etc.
• Painted or impregnated wood (which is very toxic).
• Chipboard and laminated boards.
• Driftwood (seawater).
This can damage the product and is contaminating.
NB! Never use liquids such as petrol, parafi n, rubbing
alcohol or similar for ignition. You can harm both yourself
and the product.
5.6 Consumption of fi rewood
Consumption of wood, at nominal heat output: Approx..4,3 kg/h.
The size of the wood should be:
Ignition wood (unleavened wood):
Length: 30-50 cm
Diameter: 6 - 10 cm
Quantity pr. ignition: 6 pcs. of 0,6-0,8 kg per piece and 10-12
sticks with a total weight of about ca 4 kg.
Wood to normal heating:
Wood (split wood):
Length: 30-50 cm
Quantity per. load: 1,4 kg per log and 3 logs per load, ie approx
4,2 kg / load
Filling interval: Approx. 60 minutes
Nominal heat dissipation is achieved by 60 % opening of the
air valve and 30 % of the ignition valve.
During test according to EN 13229 of inserts are used in 3
pieces (á 35 cm laid parallel to the door. kt 5 %.).
