5.3 Checking the functions (fi g. 4)
Once the product has been assembled, always check the control
handles. These must move easily, and work in a satisfactory
manner.
Jøtul I 400 is equipped with the following operating options:
Air vent fi g. 4 A
Left position closed
Right position fully open
Lighting vent fi g. 4 B
Left position Closed
Right position Fully open
5.4 Stoking the fi re
To be able to control the heat output, it is important to
have a thick layer of embers and a high temperature in the
burn chamber. Stoke the fi re with more wood when it has
burned down to embers. NB: Use a glove or something
similar to protect your hand in case the handles are hot.
• Open the door slightly and allow the pressure in the burn
chamber to even out for a few seconds before opening the
door fully. This prevents smoke and ash from spilling out.
Never put on more wood while the fi re is burning well.
• Stoke with 2 logs that together weigh about 1,6 kg. To
ensure optimal combustion, logs must NOT be higher than
the upper holes in the rear plate.
• Close the door.
• Leave the ignition vent and the air vent open for 2 or 3
minutes until the logs have turned black and are burning
well. Then adjust the ignition to 35-60% and air vents to
40% to 70%.
• The conditions for controlling combustion vary depending
on the temperature in the burn chamber and the draught
in the chimney.
• The door must be closed when the fi replace is not in use.
Important! It is important to get the wood burning quickly
and we therefore recommend that you open up the air supply.
Burning at too low a temperature and with too little air can in
some cases cause gas ignition which may damage the stove.
Warning against overheating
Never overheat the fi replace
The fi replace has been designed and tested for use at a
nominal output of 6 kW. This corresponds to a combustion rate
of about 1,7 kg of wood per hour.
The maximum amount each time is about 2 kg (2-3 logs at a
time).

Important!

Never have a fi re burning with the ignition vent fully open for
any length of time. A sure sign of overheating is when parts of
the stove glow red. If this happens, reduce the air vent opening
immediately.
Seek professional advice if you suspect that the chimney is not
drawing properly (too much/too little draught).

Odours when using the fi replace for the
fi rst time
When the fi replace is used for the fi rst time, it may emit an
irritating gas which may smell slightly. This is because the
paint on the outside is drying. The gas is not toxic but you
should open some windows to ensure the room is thoroughly
ventilated. Let the fi re burn with a high draught until all traces
of the gas have disappeared and no smoke or odours can be
detected.

5.5 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.
