5.0 Use

5.1 Choice of fuel
Always use quality wood. This will give you optimal results, any
other fuel may damage the fireplace.
5.2 Jøtul's definition of quality firewood
By good quality firewood we mean logs of, for example, birch,
beech, and pine.
Good quality firewood should be dried so that the water content
is maximum 20%.
To achieve this the wood should be chopped at the latest in late
winter or early spring. It should be cut and stacked so that air
circulates around it. The stacks should be covered on top so as
to avoid absorbing excessive rainwater. The logs should be taken
indoors in autumn for use during the winter season.
The amount of energy obtainable from of 1 kg of firewood 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 energy (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 firewood (0% humidity) produces
about 5 kWh, while firewood 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. Jøtul I 150 FL
has a nominal heat output of 6,0 kW. This is equivalent to a
consumption of approximately 2,1 kg of quality firewood per
hour.
Jøtul I 150 FL 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: 20 - 40 cm
Diameter: 2 - 5 cm
Amount per fire: 6 - 8 pieces
Firewood (split logs):
Length: 30 cm
Diameter: Approx. 8 cm
Intervals for adding wood: Approximately every 45 minutes
Size of the fire: 1,7 kg
Amount per load: 2 pieces
5.4 First time use
• 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.
N.B. Odours when using the fireplace 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 both vents fully (fig. 5A-B). (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. Gradually increase the size of the fire.
• Leave the door slightly open until the logs catch fire.Close 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 under the
baffle.
• Then regulate the rate of combustion to the desired level of
heating by adjusting the air wash vent (Fig. 5A).
Nominal heat emission is achieved when the air wash vent is
open approximately 50%.
5.6 Adding firewood
1. Each fire should burn down to embers before new firewood
is reloaded. Open the door slightly and allow the negative
pressure to level out prior to opening the door completely.
2. Add the wood and make sure that the air wash vent is fully
open for a few minutes until the wood has caught fire.
3. The air wash vent (fig. 5A) can be turned down once the
wood has properly ignited and is burning well. Check that
the afterburning (secondary combustion) starts.
