Use; Choice Of Fuel; Daily Use - Jøtul I 80 Mini Classic Installation And Operating Instructions Manual

5.0 Use

5.1 Choice of fuel

Always use quality firewood. This will give you optimal results,
and will not cause any damage to the product.
5.2 Jøtul's definition of quality firewood
With good quality firewood we mean logs of, for example: Birch,
beech and oak.
Good quality wood should be dried so that the water content is
approx. 20%.
To achieve that, the wood should be cut during late winter or early
spring, then cut and stacked to ensure proper airing and covered
to prevent it from absorbing rainwater. The logs should be taken
indoors in autumn for use during the winter season.
The amount of energy obtainable from 1 kg of wood varies very
little. On the other hand the specific weight of the different kinds
of wood varies considerably. As an example, a certain volume of
birch will provide less kWh than the same volume of oak, which
has a higher specific weight.
The amount of energy produced by 1 kg quality wood is about
3,8 kWh.1 kg of completely dry wood (0 % humidity) produces
approximately 5 kWh, while wood with a humidity level of 60%
produces only around 1,5 kWh/kg.
Consequences of using damp wood may include:
• Appearance of soot/tar on the glass, in the fireplace and in
the chimney.
• The fireplace emits little warmth.
• Risk of chimney fire as a consequence of accumulation of soot
in the fireplace, flue pipe and chimney.
• The fire may die out.
Be especially careful never to lay a fire using any of the following
materials:
• Household waste, plastic bags, etc.
• Painted or impregnated wood (highly toxic)
• Chipboard or laminated boards
• Driftwood
This may harm the product and pollute the atmosphere.
N.B. Never use combustible liquids such as petrol, kerosene, red
spirit or similar to start the fire. This may cause harm to both
yourself and the product.
5.3 Log length and amount
The maximum length of logs to be used is 40 cm.
Nominal heat emission from:
Jøtul I 80 Mini is: 6,0 kWh.
Jøtul I 80 Maxi is: 9,0 kWh.
The requirement for nominal heat emission is kg:
Jøtul I 80 Mini is: 1,9 kg
Jøtul I 80 Maxi is: 2,8 kg
of quality firewood per hour.
The Jøtul I 80 is a product that uses an extra air supply to enable
the afterburning of hazardous gases and particles. It is important
that the system is used correctly.
Another important factor for proper fuel consumption is that the
logs are the correct size. The size of the logs should be:
Kindling:
Length: Approx 35-40 cm
Diameter: 3-5 cm
Amount per fire: 8-10 pieces
Firewood (split logs):
Recommended length:
Diameter: Approx.
Intervals for adding wood:
Approximately every
Size of the fire:
Amount per load:
5.4 Initial lighting
• Light the fire as described under «5.5 Daily use».
• Light the fire for a couple of hours and ventilate any smoke
and smell from the product.
• Repeat this a couple of times.
Note! Odors when using the stove for the first time.
Painted products: The fireplace may emit an irritating gas when
used for the first time, and it may smell a little. The gas is not toxic,
but the room should be thoroughly ventilated. Let the fire burn
with a high draught until all traces of the gas have disappeared
and no smoke or smells can be detected.
Enamelled products: Condensation may form on the surface of
the fireplace the first few times it is used. This must be wiped off
to prevent permanent stains forming when the surface heats up.

5.5 Daily use

The product is intended for intermittent combustion. By
intermittent combustion one means normal use of a fireplace,
meaning that each fire should burn down to embers before new
firewood is added.
Open all vents fully. Remember: open the damper if such a
•
product is installed. (Use a glove, for example, as the handle
can become hot.)
• Place two medium sized logs in/out on each side of the base.
• Crumple some newspaper (or birch bark) between these and
add some kindling wood in a criss-cross pattern on top and
light the newspaper. Increase the size of the logs gradually.
• Leave the door slightly open until the logs catch fire.Close the
door and the ignition vent when the firewood has ignited and
the fire is burning briskly.
• Check that the afterburning (secondary combustion) starts.
This is best indicated by yellow, flickering flames at the air
chamber.
• Then regulate the rate of combustion to the desired level of
heating by adjusting the draught vent.
Nominal heat emission is achieved when the air vent is open
approximately 75%.
NB, When the product is used as an open fireplace, both doors
(Classic and Harmony) must be opened. If not, smoke gas could
escape into the room where the fireplace is installed.
5.6 Adding firewood
• Each load should burn down to embers before new firewood is
added. Open the door slightly and allow the negative pressure
to level out prior to opening the door completely.
