Daily Use - Jøtul F 371 ADVANCE Installation And Operation Manual

4.7 Danger of overheating
The fi replace must never be used in a manner that causes
overheating.
Overheating occurs when there is too much fuel and/or too
much air so that too much heat develops. A sure sign of
overheating is when parts of the fireplace 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). For further
information, see «4.0 Installation» (Chimney and fl ue pipe).
4.8 Ash removal
Jøtul F 370 Advance has an ash pan which makes it easy to remove
the ashes.
• Only remove ashes when the fi replace is cold.
• Push/pull the handle for the ash grate/ignition vent out and
in several times so that the ashes fall down into the ash
pan. Use something like a glove to grab the handle on the
ash pan.
• Make sure that the ash pan doesn't fi ll up so high that it
keeps ash from coming through the grate into the pan.

5.0 Daily use

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 happens because
the paint dries.The gas is not toxic but the room should be
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.
Heating advice
NB: Logs that have been stored outdoors or in a cold room
should be brought indoors 24 hours before use to bring them
up to room temperature.
There are various ways of heating the stove but it is always
important to be careful about what you put in the stove. See
the section on "Wood quality".
Wood quality
By quality wood we mean most well-known types of wood such
as birch, spruce and pine.
The logs should be dried so that the moisture content is no
more than 20%.
To achieve this, the logs should be cut during the late winter.
They should be split and stacked in a way that ensures good
ventilation. The wood stacks should be covered to protect the
logs from rain. The logs should be brought indoors during early
autumn and stacked/stored for use in the coming winter.
18
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.
Wood consumption
Jøtul F 370 Advance has a nominal heat output of ca. 6 kW.
Use of wood, with nominal heat emission: Approx. 2,1 kg/h.
Another important factor for proper fuel consumption is that
the logs are the correct size. The size of the logs should be:
Kindling:
Length: 27-30 cm
Diameter: 2-5 cm
Amount per fi re: 6-8 pieces
Firewood (split logs):
Length: Ca 27 - 30 cm
Diameter: Approx. 8 cm
Intervals for adding wood: Approximately every 45 minutes
Size of the fi re: 1.6 kg
Amount per load: 2 pieces
Nominal heat output is achieved when the ignition and air vent
is open approximately 22% (fi g. 30 A), pulled out about 12,5
mm.
5.1 How wind and weather affect the
stove
The performance of the stove can be affected considerably by
the wind acting on the chimney at different strengths. It may
therefore be necessary to adjust the air supply to ensure good
combustion performance. It might also be a good idea to install
a damper in the fl ue pipe so that the chimney draught can be
regulated according to the strength of the wind.
Fog and mist can have a signifi cant impact on the chimney
draught and it might be necessary to use other combustion air
settings to ensure good performance.
5.2 The importance of the chimney
The chimney is the engine that drives the fi replace and it's
essential to have a good chimney in order for the fi replace
to function properly.
The draught in the chimney creates a vacuum in the stove.
The combustion air is also used for the airwash system that
keeps the window clear of soot.
The draught in the chimney is caused by the difference in
temperatures inside and outside the chimney. The greater
the temperature difference, the better the draught in the
chimney. It is therefore important to allow the chimney to reach
operating temperature before adjusting the air vents to restrict
combustion in the stove (a brickwork chimney takes longer to
reach operating temperature than a steel chimney).
